13 Surprising Causes of Constipation

By Amanda Gardner

What causes constipation? Well, the obvious culprits include a low fiber diet, repeatedly ignoring the urge to go, not drinking enough water, or a lack of exercise. But constipation also has other, less-well-known causes, including certain medications and supplements, as well as potentially serious medical conditions. What’s causing your gut trouble?

Here are 13 possible causes of constipation you may not have considered.

Possible Cause No. 01 : Hypothyroidism Hypothyroidism, or an underactive thyroid gland, slows the body’s metabolic processes—even the gut. Not everyone with an underactive thyroid has constipation, nor do all cases of constipation mean that the butterfly-shaped gland in your neck is underperforming. Still, "when I see a young person who’s constipated more than normal and really complaining, I do tend to get a thyroid level," says Carla H. Ginsburg, MD, assistant professor of medicine at Harvard Medical School in Boston.

Possible Cause No. 02 : Painkillers

Painkillers, specifically narcotics, can cause constipation. "A lot of receptors for the narcotic class of drugs are in the digestive tract, so it tends to bring everything to a halt," says Thomas Park, MD, a gastroenterologist with the University of Rochester Medical Center Park in New York. "In general, it?s a good idea for everyone who?s placed on one of these drugs to also place them on a gentle laxative like a stool softener." Some studies (but not all) have suggested that there might be a higher risk of constipation for people who are chronic users of pain relievers like aspirin and ibuprofen.

Possible Cause No. 03 : Chocolate

There’s some evidence that chocolate can cause constipation, though other studies show chocolate may actually help some people, Dr. Park says. In one 2005 study, people with chronic constipation or irritable bowel syndrome were more likely than people without those problems to say that chocolate caused constipation (as did bananas and black tea). Eliminate or cut back on chocolate if you think it could be causing your constipation.

Possible Cause No. 04 : Vitamins

Vitamins in general won’t cause constipation, but certain components, such as calcium and iron, can be a problem. "I would tell a patient to stop taking the iron [or calcium] unless they really need it and, if they do need it, I would put them on a stool softener to counteract that," says Dr. Ginsburg, who is a spokesperson for the American Gastroenterological Association.

Possible Cause No. 05 : Laxative Overuse

Some laxatives work by stimulating bowel activity. Such stimulant laxatives should be taken only as directed. If used for long periods of time, stimulant laxatives can lead to dependence, meaning your body simply won’t function properly without them. Stimulant laxatives include Dulcolax, Ex-Lax, Senna, and others. Don’t take any medication—including laxatives—for longer than instructed by either the product’s label or your doctor.

Possible Cause No. 06 : Too Much Dairy

A diet high in cheese and other low-fiber/high-fat foods such as eggs and meat can slow down your digestion. The obvious solution? Cut down on your intake of such foods, and increase fiber intake to 20 to 35 grams a day. "If you?re going to have cheeses and red meat and eggs, mix in some salads or other foods that have fiber," Dr. Park advises. And avoid fast foods and processed foods, which are generally low in fiber.

Possible Cause No. 07 : Antidepressants

Constipation can be associated with selective serotonin reuptake inhibitor (SSRI) antidepressants such as Prozac (fluoxetine). However, constipation is more of a problem with older tricyclic antidepressants such as Elavil (amitriptyline), says Dr. Park. Why any of these drugs have this effect isn’t clear, though. If you’re taking an antidepressant and have this side effect, think about using a gentle stool softener.

Possible Cause No. 08 : Depression

Ironically, the very condition that antidepressants are meant to treat—depression—can also cause constipation. Like hypothyroidism, depression causes a general slowdown of the body’s normal processes, which can also affect the bowel. People with irritable bowel syndrome, which can be closely linked to depression, are also prone to constipation, Dr. Park says.

Possible Cause No. 09 : Antacids

Antacids are great for fighting heartburn, but some can cause constipation, particularly those containing calcium or aluminum, Dr. Park says. Fortunately, the drugstore aisles are crammed with options, so if one medication is a problem you can try something else. You can also cut down on your risk of heartburn by not overstuffing at meals. And consuming fewer fatty foods and more fiber will help prevent both problems.

Possible Cause No. 10 : Blood Pressure and Allergy Medicines

Constipation can be a side effect of some common drugs used to treat high blood pressure, such as calcium channel blockers and diuretics. Diuretics, for instance, lower blood pressure by increasing urine output, which flushes water from your system. However, water is needed to keep stools soft and get them out of the body. Antihistamines used to treat allergy symptoms can be a problem too.

Possible Cause No. 11 : Inflammatory Bowel Disease (IBD)

Inflammatory bowel disease (IBD) includes two chronic conditions—Crohn's disease and ulcerative colitis. Both can cause cramping, weight loss, bloody stools, and other health problems. Chronic diarrhea is a common symptom of both. However constipation can be a problem too. In ulcerative colitis, constipation can be a sign of inflammation in the rectum and in Crohn's disease it can be a sign of an obstruction in the small intestine. However if you have constipation alone, without other symptoms, it's unlikely to be due to IBD.

Possible Cause No. 12 : Childbirth

Constipation is common during pregnancy, but childbirth itself can be a problem, possibly due to sluggish abdominal muscles or perhaps the use of pain relievers or an anesthetic during the delivery. Also, "there may be some perineal soreness right after the delivery, so the fear of causing more discomfort may be an important factor in the constipation," says Dr. Park. Although stretch injuries during childbirth can sometimes cause nerve damage that leads to constipation, this is less common.

Possible Cause No. 13 : Diabetes and Neurological Conditions

Diabetes can cause nerve damage that can affect a person’s ability to digest food, says Dr. Park. Most people with advanced diabetes know they have it. Still, it’s reasonable to do a blood sugar test on someone who is regularly constipated, says Dr. Ginsburg. Neurological conditions such as multiple sclerosis or Parkinson’s disease can cause constipation. Usually, though, "this goes with another symptom such as trouble urinating, double vision, or a gait problem," Dr. Ginsburg says.

Aging and the pH Miracle Diet

When many people hear the word “diet” they immediately think of weight loss. The focus on thinness in our society has equated this word with shedding a few pounds. However, diet really means any food or drinks you put into your body. The diet that you consume has a profound impact on your overall health. The pH miracle diet is not just a diet for weight loss. In fact, the first volume of this popular series was dedicated to health in general. The original pH miracle diet book focuses on many issues, including aging.

What does aging have to do with pH and acid/alkaline foods? Some experts contend that the reason we age has to do entirely with the amount of acidic foods that we eat. The theory is that we get older because we do not effectively get rid of the wastes and toxins that accumulated through our bodies.

We burn nutrients within our cells to get energy, maintain our body temperatures and get our bodies to function correctly. No matter what type of food you eat, vegetable or meat, acid or alkaline, gourmet food or junk food, they are composed of the same elements: carbon, nitrogen, hydrogen and oxygen.

In order to function correctly, the cells use these nutrients. They “oxidize” them or burn them up into natural acids: carbonic acids, uric acids, lactic acids and fatty acids. The cells expel these acids as waste into urine and sweat. When the body is functioning properly and in a balanced manner, these waste acids are no problem. The body can get rid of them quickly and easily, and you can maintain a normal pH of around 7.4.

However, the modern way of living has resulted in our bodies not being able to rid themselves of the acids correctly. Lack of sleep, lack of exercise, overwork, stress, smoking, pollution and high acid diets (heavy in meat and dairy products) all prevent our bodies from properly expelling these acids. There is too much acidic production from these lifestyle and diet factors, and the body simply cannot get rid of it.

Even worse, modern farming and food production practices are making foods more acidic than they used to be. Inorganic acid minerals like chlorine, phosphor and sulfur seep into meats, grains and root crops through soil, air quality and farming practices. We are consuming more inorganic acid minerals than ever before. All of this contributes to our bodies’ inability to rid themselves of acid.

The pH miracle diet is a perfect balance to our over-acidified lives that cause premature aging. Aging occurs because of the build up of acidic elements in the body. Healthy cells naturally have a slightly alkaline pH level, and since acid and alkaline are chemical opposites, high acid levels destroy cells.

In order to stop aging and reverse the affects of acidic damage on the cells, you must start alkalizing your diet according to the principles set out in the pH miracle diet. You must help you body develop a better system to rid itself of the acid wastes. Then you must facilitate it in pulling old wastes out of your body.

The first step requires that you drink plenty of water, especially acid free alkaline water. Just 4 glasses of alkaline water is more effective than 8 glasses of regular water. Water ionizers are available to help you create alkaline water in the comfort of your home. This water will help flush out your system and get rid of the build up acidity within it.

The pH miracle diet also encourages people to eat a higher percentage of alkaline foods in their diet. The alkalizing foods will help restore balance to the body and push the remaining acid waste build up out of the body. According to pH miracle diet fans, the results are a more youthful glow, more energy and a relief from some of the symptoms of aging, like arthritis.

Five Important Things To Know About Vitamins

(from Black Health Magazine)

There’s an abundance of vitamins to choose from when you’re deciding which kind of is good for you. Making the choice of which multivitamin or which ever vitamin will help aid or strength is a task within itself. Its important to know and understand the benefits, cons and value. Below are five interesting items that will hopefully help you understand more about vitamins.

1. They Matter

Vitamins and minerals are substances your body sometimes needs for normal growth and functioning. Some facilitate crucial chemical reactions, while others act as building blocks for the body.

Nutritionists call vitamins and minerals “micronutrients” to distinguish them from the macronutrients such as proteins, carbohydrates, and fats that make up the bulk of our food. While micronutrients are vital for the proper processing of macronutrients, they’re needed in smaller quantities. Think of it this way: If macronutrients are the gas in your engine, then micronutrients are like the motor oil, coolant, and battery fluid.

Micronutrient deficiency can lead to acute diseases with exotic names like scurvy, pellagra, and beriberi. Deficiency diseases were common in the U.S. until the 1940s, when the FDA-mandated fortification of common foods like bread and milk. These diseases are still common in many poorer countries.

2. Maintaining a Healthy Diet

It’s easy to get enough micronutrients from your food if you maintain a healthy diet, Audrey Cross, PhD, associate clinical professor of nutrition at Columbia’s School of Public Health, tells WebMD. But most people fail that test; they’ll eat two or three servings of fruits and veggies per day rather than the recommended five. That’s why Cross (and many other nutritionists) suggest a multivitamin as a sort of nutritional safety net for many of their patients.

But it’s just a safety net. So-called “whole foods” like veggies and whole grains contain fiber and a host of other important nutrients that can’t be adequately delivered through pills. In fact, scientists are still finding new “trace elements” in whole foods that may someday be labeled essential to health — but aren’t found in any pill.

“There are literally thousands of these compounds, and we’re just scratching the surface on knowing what their role is,” says David Grotto, a registered dietitian and spokesman for the American Dietetic Association. “We’re sending the wrong message if people believe they’ve got everything under control and if they’re taking vitamins while eating a horrible diet.”

3. Choosing a Supplement

It’s easy to become overwhelmed when looking at the dietary supplement shelves of a health food store or even your local supermarket. While many of the health claims are unproven or downright bogus, some supplements may be useful for some groups.

Major multivitamin makers typically produce different varieties for men, women, children and older folks. Picking a pill that fits your group makes sense, says dietitian Grotto, as the optimal level of various nutrients varies by age and sex. For example, premenopausal women need more iron than children or the elderly, he says.

But the elderly have a harder time obtaining adequate amounts of vitamin B-12 from natural sources, so the need for supplementation may increase with age, says Lynn Bailey, a University of Florida nutritionist who teaches courses on vitamins.

Folate, or folic acid, is key to preventing birth defects (such as spina bifida), Bailey says. Bailey says all women of childbearing age should ensure they get 100% of the RDA of folic acid through fortified food or a multivitamin.

4. Calcium and Vitamin D

Calcium supplements are also important for certain age groups, Bailey says. The Institute of Medicine, part of the National Academy of Sciences, recommends that adolescents get 1,300 milligrams of calcium a day. One cup of milk or calcium-fortified orange juice contains about 300 milligrams of calcium.

Other sources of calcium include cheese, tofu, yogurt, vegetables, and beans. A typical calcium supplement may contain 500 milligrams or 600 milligrams of calcium. Bailey gives her 15-year-old son a daily calcium supplement at dinnertime. People over 50 should get 1,200 milligrams a day of calcium to ward off osteoporosis (thinning of the bones), Bailey says.

Federal dietary guidelines recommend that the elderly, the homebound, and people with dark skin boost their vitamin D intake with both fortified foods and supplements to reduce the risk of bone loss. Vitamin D helps with absorption of calcium; often calcium supplements will also contain vitamin D. (The full federal guidelines, updated in 2005, are available at www.health.gov/dietaryguidelines.)

Special groups such as smokers, pregnant women, or people recovering from traumatic injury may need additional supplements, Cross says. Decisions to take supplements beyond a multivitamin are best made with your doctor or registered dietitian, she says.

The evidence is strong that a healthy diet can ward off chronic diseases like cancer and heart disease. What’s less clear is if big intakes of particular micronutrients can boost that preventive effect further.

There is promising evidence that the mineral selenium could prevent a variety of cancers, says Alan Kristal, DrPh, associate chief of cancer prevention at the Fred Hutchinson Cancer Research Center in Seattle. But beyond selenium, the data aren’t promising, Kristal says. For example, there’s no solid evidence that taking large doses of antioxidants like vitamins B or C have any beneficial effect.

5.Controversial Health Claims

As you seek the proper multivitamin or dietary supplement, it’s best to keep your guard up. The supplement industry is relatively unregulated, and you can injure or even kill yourself with “natural” products bought at your neighborhood supplement store.

Many health claims attached to multivitamin formulations are doubtful, but harmless. Some men’s multivitamins contain extra lycopene, a substance once thought to prevent prostate cancer. But Kristal, the cancer specialist, says support for that claim is waning. “If indeed lycopene did anything, [supplements] don’t have enough to make a difference,” he says. Multivitamins aimed at women are often spiked with green tea or ginseng extract; the effect of these on weight control is yet unproven.

More dangerous are recommendations of vitamin megadoses to treat obesity, depression, carpal tunnel syndrome or other problems. At best, megadoses are a distraction from real treatments for these problems, experts say. At worst, they can cause injury or death.

So-called fat-soluble vitamins — that is, vitamins A, D, E, and K — accumulate in the body, making overdosing a real threat. Vitamin overdoses have been associated with liver problems, weakened bones, cancers, and premature mortality.

Until recently, water-soluble vitamins such as B and C were considered nontoxic, even at high doses. But now evidence is emerging that B-6 megadoses can cause serious nerve damage, Bailey tells WebMD.

Despite the warnings, the quest for a magic pill plunges ahead. Cross chuckles when patients show her weight loss supplements that claim wondrous effects “when taken in combination with a sensible diet and exercise.” Her response: Wouldn’t a sensible diet and exercise do the trick even without the supplement?

Benefit of Using Liquid Vitamins

Should you take Liquid vitamin supplements?

Nowadays, it is hard to escape hearing about so called liquid vitamins, as they are advertised everywhere on the internet it seems.

Liquid vitamin supplements have an almost total absorption rate, often quoted as high as 98%.

Accompanying this claim is another one: 90% of the nutrients taken in a tablet or pill form are going straight down your toilet.

But are these claims true? Are there any real benefits to liquid vitamins? Are there drawbacks?

At Liquid-Vitamins.org we will present the facts, and let each of you make up your own minds.

The facts on Liquid Vitamins: Liquid Vitamin Supplements

First, let's begin with the claim that supplements taken in tablet or pill form are 90% excreted and wasted.

This is a very (intentionally!) misleading statement.

Here's why: there is a huge variation in supplement quality.

On one end of the spectrum, you have cheap vitamins mass produced and sold in supermarket chains. These supplements are made using the cheapest ingredients possible, as well as the cheapest excipients (excipients are what bind the ingredients together).

Because of the excipients used, the nutrients are mostly released in the stomach, and, therefore, destroyed by the stomach acids.

In the case of these supplements, 90% of the vitamins can indeed end up wasted in the toilet.

+++++++++++++++++++++++++++++++++++++++++++++++++++

Absorption of Liquid Vitamins

"Liquids, aside from offering the obvious benefit of being easy to swallow, have another very important trait. According to the Physicians Desk Reference,

Liquid is absorbed at a 98% rate, versus

Only 10 – 20% in hard capsules or tablet forms.

This very important distinction is extraordinarily important. It is not uncommon to have [hard] capsules pass right through the body in a way that the product name is still visible after the pill has left the body completely. This does not happen with liquids, as they are absorbed completely and are not wasted."

+++++++++++++++++++++++++++++++++++++++++++++++++++

On the other end of the spectrum, though, there are companies that manufacture highly sophisticated supplements, often referred to as nutraceuticals. These companies can use extremely expensive all natural, potent ingredients and excipients.

Some of these supplements, due to these differences, have highly sophisticated delivery systems. For example, the best of them have excipients that ensure the nutrients are absorbed via the lining of the walls of the upper intestine, allowing them to enter the bloodstream where they go to work.

In short, it is dishonest for these purveyors of liquid vitamins to try and claim all tablet or pill form supplements have poor absorption. Comparing supermarket variety vitamins to sophisticated nutraceuticals is like comparing apples to oranges.


Absorption of Liquid Vitamins

Now, let's discuss the alleged 98% (or greater) absorption claimed by some of these liquid vitamin supplements.

Sadly, this is also misleading.

There are only a few different ways in which nutrients can get into your bloodstream:

1) By injection...must be performed by a clinic or physician. For example, vitamin B12 or Human Growth Hormones can be introduced into the body using this route.

2) Through the mucous membranes of the mouth via a sublingual tablet or liquid. This can be highly effective for certain nutrients, but does not work for many others simply because many nutrients possess molecules that are too large to be absorbed via the mucous membranes.

3) Via the lining of the walls of the upper intestines. (Discussed above, this is how many of the best nutraceuticals work).

4) Via the lining of the colon walls using suppositories (which are prescription items and are not applicable to supplements).

5) No specific delivery system.

It is the last category that cheap vitamins you buy in the supermarket fall into, as well as so called liquid multi vitamins.

In short, these cheap supplemements and liquid vitamin supplements are simply drank as is, or mixed with water or juice before imbibing. They then enter the stomach where the vast majority of the active nutrients are destroyed.

The bottomline is that these companies that market liquid vitamin supplements are taking advantage of the fact that most people are not equipped with an understanding of the principles behind absorption and bio-availability, and can present their liquid vitamins as having greater efficacy than they truly do, while at the same time "knocking down" supplements that come in tablet or pill form.


Other facts that manufacturers of Liquid Vitamins don't want you to know

If you follow the latest breaking health trends as we do, you may be aware of the many benefits of enzymes, which have been revealed to possibly help disorders ranging from the caridovascular to the circulatory to the health of the lungs, kidneys, liver, and even brain. A good amount of this research is being conducted by Medical Scientists at the prestigious Harvard Medical School.

Many sellers of liquid vitamins will often extol the virtues of enzymes and claim their products harbor all of the beneficial enzymes that you need.

Don't buy the hype.

The fact of the matter is that the enzyme component in these products are negligible because the enzymes are not added, and therefore only contain trace amounts, which were present in the food matrix.

What's worse, enzymes cannot be added to liquid vitamins because enzymes are highly sensitive and can only survive in a liquid form for approxiately 2 to 3 hours.

Enzymes, however, can be a viable component in complex tablet form nutraceuticals and not suffer destruction like they do in liquid vitamin supplements.


Liquid-Vitamins.org's Verdict on Liquid Vitamins

In our opinion, liquid vitamins are on a par with respect to efficacy as cheap supplements you can buy in any supermarket. Unfortunately, most of these liquid vitamin supplements are not cheap (especially for what you are getting) at all.

Indeed, many of them command prices of 40 dollars and upwards -- this is primarily due to the way these liquid vitamins are marketed, which is MLM (Multi-level-marketing). Multi-level-marketing schemes have a strong tendency to inflate the retail prices of the products because there are many levels of payment made to those marketing them.

In the final analysis, the only real benefit we can ascertain of taking liquid vitamin supplements is that some people have difficulty swallowing any tablets.

If you are one of these people, then taking a liquid multi vitamin will probably be better than taking nothing at all.

However, liquid vitamin supplements cannot compare to sophisticated nutraceuticals for the reasons cited above -- and many more.

Those interested may read up on the line of nutraceuticals we here at Liquid-Vitamins.org personally take ourselves. We hope you have found our liquid vitamins review helpful.

We believe, in the end, people should be allowed to make up their own minds what they want to take or not.

+++++++++++++++++++++++++++++++++++++++++++++++++++++

The National Advisory Board states that:

'100 mg consumed in tablet form translates to a minute stabilized 8.3 mg or 8.3% concentrated in the blood.'

This is simply not the case with liquids!"

"Pills and capsules may cost less, but in reality you get far less absorption for your money. No wonder they cost less!

Liquids are fast--you do not even have to wait for them to dissolve. They start working as soon as you swallow and

Many have very pleasant flavors."

What is Vitamin B1?

Vitamin B1, also known as thiamin, helps fuel your body by converting blood sugar into energy. It keeps your mucous membranes healthy and is essential for nervous system, cardiovascular and muscular function.
Nutritionists categorize vitamins by the materials that a vitamin will dissolve in. There are two categories: water-soluble and fat-soluble vitamins. Water-soluble vitamins, which include the B-complex group and vitamin C, travel through the bloodstream. Whatever water-soluble vitamins are not used by the body are eliminated in urine, which means you need a continuous supply of them in your food. Vitamin B1 is a water-soluble vitamin.

How Much Vitamin B1 Is Enough?

Women should have 1.1 milligrams every day, and men should have 1.5 milligrams every day.

Sources of Vitamin B1
The best sources of Vitamin B1 are yeasts and liver. The following foods are good sources of Vitamin B1:

Pork
Whole-grain cereals
Rye and whole-wheat flour
Wheat germ
Navy beans and kidney beans
Can You Have Too Much or Too Little?
It's pretty rare in the United States for a person to be deficient in this vitamin. A lack of it can cause beriberi, a condition that involves confusion, muscle wasting, nerve problems and a rapid heartbeat. It's usually only seen in the United States in babies who are fed formula that isn't supplemented with Vitamin B1 or in people who drink large amounts of alcohol. People who drink heavily should talk to their doctors about how to quit drinking and whether they need vitamin B1 supplements.

Vitamin Storage
If you want to get the most vitamins possible from your food, refrigerate fresh produce and keep milk and grains away from strong light. Vitamins are easily destroyed and washed out during food preparation and storage. If you take vitamin supplements, store them at room temperature in a dry place that's free of moisture.

Benefits of Vitamin A

Vitamin A, also called retinol, helps your eyes adjust to light changes when you come in from outside and also helps keep your eyes, skin and mucous membranes moist. Vitamin A mostly comes from animal foods, but some plant-based foods supply beta-carotene, which your body then converts into Vitamin A. It also has antioxidant properties that neutralize free radicals in the body that cause tissue and cellular damage.
Early information from scientific studies suggests that beta-carotene might help people who already have Coronary Artery Disease (CAD). The American Heart Association doesn't recommend taking supplements of beta-carotene until more is known, however.

Nutritionists categorize vitamins by the materials that a vitamin will dissolve in. There are two categories: water-soluble and fat-soluble vitamins. Fat-soluble vitamins ”vitamins A, D, E and K”are stored in the fat tissues of the body for a few days to up to six months. If you get too much of a fat-soluble vitamin, it can be stored in your liver and may sometimes cause health problems. Vitamin A is a fat-soluble vitamin.

Some people take mega-doses of fat-soluble vitamins, which can lead to toxicity. Eating a normal diet of foods rich in these vitamins won't cause a problem. Remember, you only need small amounts of any vitamin. In the case of vitamin A, overconsumption has been linked with an increased risk of fractures in postmenopausal women.

Some health problems can make it hard for a person's body to absorb these vitamins. If you have a chronic health condition, ask your doctor about whether your vitamin absorption will be affected.

How Much Vitamin A Is Enough?

It's recommended that women consume 800 mcg and men consume 1000 mcg of vitamin A daily.

Sources of Vitamin A

Top sources of vitamin A include:
Beef liver
Egg yolk
Cheddar cheese
Fortified milk

Top sources of beta-carotene include:

Sweet potato
Carrots
Pumpkin
Cantaloupe
Broccoli
Apricots
Spinach and collard greens

Can You Have Too Much or Too Little?

Vitamin A deficiency is rare in the United States, but it can cause night blindness, eye inflammation, diarrhea and other problems. Overconsumption of vitamin A can cause nausea, irritability and blurred vision in its mild form. In addition, the palms of the hands and the bottoms of the feet can turn orange if a person has a high intake of Vitamin A. Vitamin A toxicity can cause growth retardation, hair loss and enlarged spleen and liver in its more severe form. Vitamin A overdose can also cause birth defects and has been linked to increased risk of bone fractures in some people.

Vitamin Storage

If you want to get the most vitamins possible from your food, refrigerate fresh produce, and keep milk and grains away from strong light. Vitamins are easily destroyed and washed out during food preparation and storage. If you take vitamin supplements, store them at room temperature in a dry place that's free of moisture.

Do you know that too much vitamin A is not good?

Too Much Vitamin A May Put Some Women at Risk for Hip Fractures

For women who consume large amounts of vitamin A, also known as retinol, lowered bone mass and an increased risk of hip fractures may result, say researchers from the Harvard School of Public Health in a recent issue of the Journal of the American Medical Association.

Previous research has shown that too much vitamin A in the diet can suppress the body's ability to make new bone and may actually reduce a person's existing bone mass, thereby increasing the risk of fractures. Researchers studied over 72,000 postmenopausal women for 18 years to assess the relationship between high vitamin A intake from foods and supplements and the risk of hip fractures. The women in the study completed regular food questionnaires and provided information about health habits, use of hormones and supplements and weight.

During the 18-year study period, over 600 women experienced hip fractures. Women who had the highest total vitamin A intake had a significantly higher risk of hip fracture when compared to women who consumed the least amount of vitamin A. The researchers maintained that the increased risk was mainly attributable to retinol, the vitamin A found in foods of animal origin, not beta carotene, which is contained in fruits and vegetables and can be converted to retinol by the body.

Vitamin A, a fat-soluble vitamin, is an important dietary element - it is involved in the formation and maintenance of healthy skin, hair and mucous membranes. How much vitamin A is too much? The 1989 RDA for vitamin A has been set at 800 retinol equivalents (RE) per day for women 19 to 50 years of age, and 1,000 retinol equivalents for men 19 to 50 years of age, so check your multivitamin or supplements to make sure you̢۪re not exceeding that amount. Remember, too, that foods contain vitamin A - one carrot has about 2025 RE of vitamin A, which is 203% of a man's recommended daily intake.

Multivitamins – A Ticket to Daily Health !!

SocialTwist Tell-a-Friend

An increasingly number of the world’s population is now eager and interested in looking after their health and in keeping tune with their well-being. It is important to note that this awareness is progressively contributing to the creation of several health supplements to benefit both the adults and the young ones. Dietary and vitamin supplements have constantly proven their worth to health conscious individuals.

An excellent daily multivitamin supplement does not only develop your general bodily functions but also improves your mental and physical condition and well being. Occasionally specification is needed in appropriately supplementing nutrients to deal with any individual needs. An example would be in heart disease patients, they would have to take in CoQ10 in preventing the said condition. Alzheimer’s disease can be effectively prevented by a regular combination of Vitamin C and E intake.

Multivitamin supplements necessarily include all the vitamins and nutrients essential for recommended daily dosage. Multivitamin supplements may also be formulated to meet the needs of individual conditions like pregnancy and specific age brackets. It is a well settled fact that multivitamins in liquid form are more efficient than the ordinary pill forms. This is due to the fact that the body can easily absorb liquid nutrients five times more than ordinary multivitamins in tablet or capsule form.

Basically, the body needs 13 essential vitamins to function properly. In regulating the crucial performance of the body, it has to have vitamins A, B, C, D, E, K, B12, and the 7 B-complex vitamins. Majority of these vitamins are obtained by our body through the food that we eat. The danger of illness or even mortality is in the deficiency of some of the essential vitamins. This is where vitamin supplementation comes in. It counteracts the illness caused by such deficiency. With this fact, it is very unlikely for someone to refuse vitamin supplementation on a daily basis. So the question now is, why is it necessary for individuals to take multivitamins when majority of our daily diet can provide us with the basic nutrients we need? It may not be compulsory, but everyone can profit from daily multivitamins.

As previously mentioned, the clear benefit of daily intake of multivitamins it to prevent vitamin/nutrient deficiency. Some personal circumstances may increase dietary needs. Pregnant women, during their first trimester, are recommended by their doctors to take multivitamins. This does not only provide the mothers with sufficient nutrition but also proper vitamins to benefit the unborn child inside their womb. Taking multivitamins everyday reduces the risk of transmitting malnutrition from a pregnant woman to her unborn baby. Other conditions such as old age, alcoholism, smoking, and exposure to excessive pollution have long-term detrimental effects to the body system which can be successfully counteracted by multivitamins.

Stress is also one risk factor which needs serious supplementation that multivitamins can provide. Especially with people who have so much to do and have a hard time in keeping up with their health needs, multivitamins are a must to keep them always on the go without any health complications in the long run. Stress formulations benefit both your mental ability and daily endurance. Aside from the mentioned benefits, daily multivitamins also minimize the risk of cancer or any cardiovascular disease.

Several people, if not all, testify to have a feeling of comfortable health in regularly taking in multivitamins. This is due to the synergistic or combined effects of the supplemental ingredients found in multivitamins. A fat-soluble antioxidant vitamin, like the Vitamin E, works to neutralize probable harmful free agents in the body. This vitamin also maintains healthy skin through protection of cell membranes, blood circulation, heart, nerves, red blood cells, and muscles. Another antioxidant is the Vitamin C which effectively fights blood cell infection and is vital in collagen formation, wound healing, and formation of bone structures, capillaries, and teeth. Vitamin is also helpful in the iron absorption from plant sources. Vitamins A, D, K and other supplemental nutrients found in multivitamins have specific functions that benefit the bodily functions.

While daily intake of multivitamins may have proven beneficial, it is not a 100% guarantee to be free of serious illness attributed to other factors. It is often a misconception that symptoms of disease may always be cured by taking multivitamins. Health experts have the better opinion of immediate medical assistance rather than resorting to multivitamins alone.
