Oh dear. I do take an extra niacin supplement for hypertension. Now, I will have to be careful to take an extra B complex. I guess we all knew that taking one B vitamin alone is not good.

By Dr. Gabe Mirkin, M.D.
One in three women and one in four men in the United States take vitamin pills regularly.

This month, a study that followed 182,099 people in California and Hawaii for an average of 11 years showed that taking multivitamin pills neither decreased nor increased the death rate for all causes or the rates of heart attack or cancer (American Journal of Epidemiology, August, 2011).

A previous review of 67 randomized trials of vitamin pill effects on life and health found that taking vitamin pills may shorten life (Cochrane Database of Systematic Reviews, Issue 1, 2008).
The authors found an increased death rate of 16 percent in those taking vitamin A pills, seven percent with beta- carotene, and seven percent with vitamin E.

The Women�s Health Initiative study followed women for eight years and found that taking multivitamin pills has little or no influence on the risk of common cancers, heart attacks or death rate in postmenopausal women (Archives of Internal Medicine, February, 2009).

A review of the world�s literature shows that multivitamin use neither increases nor decreases risk for breast cancer (Annals of Pharmacotherapy, published online April 2011).

VITAMIN D FROM SUNLIGHT, NOT PILLS
Vitamin D is the only vitamin that appears consistently in the literature to help prevent heart attacks and cancers, and that benefit is related more to the fact that you can get it from sunlight (Cancer Epidemiology, Biomarkers & Prevention, April 2011).

The Swedish Women�s Lifestyle and Health cohort study followed women for up to 15 years and found that women who got sunburned twice or more per year during adolescence live longer than those who had been sunburned less than that.

Women who went on sunbathing vacations more than once a year lived longer and suffered fewer heart attacks.

VITAMIN B PILLS MAY CAUSE HARM

Every chemical reaction in your body is started by an enzyme.
For your body to convert chemical A to chemical B, you need an enzyme to start that reaction. All eight B vitamins are parts of enzymes. When you take large doses of one enzyme, you accumulate end products that must be balanced by also taking large doses of other enzymes.

People who take large doses of niacin to lower cholesterol have a marked elevation of homocysteine, a risk factor for heart attacks.

Here is how it happens: Proteins are made up of building blocks called amino acids.

The B vitamin, Niacin, is part of the enzyme that converts an amino acid, cysteine, into homocysteine.

Three other B vitamins, folic acid (B9), cobalamin (B12), and niacin (B3)} protect you from accumulating too much homocysteine by breaking down homocysteine and converting it to cysteine.

Therefore, when you take large doses of niacin, you also have to take large doses of the other three vitamins to protect you from accumulating homocysteine.

And you believe this study?

And how large is large for a dose of niacin?

And who sponsored the "Woman's Health Initative"?

this study contradicts thousands of other studies out there.

jfh, why not get your homeocystine levels checked and report back to us.

and don't you take betaine?

The study makes sense in some respect. But I also question how large and professional were the studies. He only talks about the multivitamin study sample.

I've always known that taking a single B vitamin can get the rest out of balance. So, I consider it a precaution to address it with taking B in a complex aside from multivitamin. I also remind people. It does not matter how much of a B one takes, it is easy enough to take an extra complex. I feel the same way about B12.

Yes I take betaine in the form of TMG. Why do you ask Arrow?

Doesn't TMG mitigate the homocystine formation in some way? I thought that I read that.

First, it would be difficult to get vitamin D from the sun year round, especially in Canada where I live.

Secondly, you can't possibly eat enough fruit and berries to get the required vitamin C. (10,000mg of C = approx 400 oranges).

Finally, there are cheap multivitamins and there are those made from organic whole foods. Most people use the cheapest ones, and I doubt if they will improve health or protect from disease, nevermind allow for a longer life.

The bottom line is that most soil is depleted of vitamins and minerals, therefore, supplementation is a must for good health. Just remember to not buy your vitamins from Walmart... and don't believe every "study" you read..

ok lets say this is true for the sake of argument...it applies to the multivitamin,to vitamin a,b,c,d etc etc...

does it also apply to zinc,selenium,spirulina,olive leaf extract,echinacea...shit probiotics as a supplement(not yogurt)??

I have a kitchen cabinet dedicated to and full of various supplements. I won't change my way of life due to one article from an MD I've never heard of. However, the B vitamin section makes sense. I do take separately pantothenic acid, niacin, and B12 and will continue to do so, but continue to include a whole B50 complex just in case. ...and just thought it was an article worthy of presentation for debate or support.

Everything I take comes from food in a bottle. When I read that a certain vitamin or items helps with this or that, I look up which product has that certain item and take more.

Lately I have been including a product with whey and have been losing inches.

The vitamins and minerals that we take to supplement our diets must come from a whole food source in order for the body to use it properly. If not, the body doesn't recognize it as a true vitammin or mineral and flushes it out of the body. Worst case scenario, if the multivitamin isn't flushed out of the body then the body will cause it to crystalize. After that stage, it turns into a free radical which a is the precursor to cancer.

I feel the same way. If the nutrients are not available in the body to complete the vitamin supplement, free radicals are formed.

Vitamins from whole food sources are always the best, but remember that most vitamins function as coenzymes or cofactors. A nonprotein component of enzymes is called the cofactor. If the cofactor is organic, then it is called a coenzyme. Coenzymes are relatively small molecules compared to the protein part of the enzyme. Many of the coenzymes are derived from vitamins.

The body cannot directly utilize synthesized vitamins, but must convert them by adding a phosphate group (usually from adenosine triphosphate, i.e., ATP) in order to become active coenzyme form vitamins. For most healthy people, the process of converting synthesized vitamins into coenzyme vitamins is not difficult. However, for individuals who are not healthy or who are nutritionally deficient, this conversion process can be significantly more difficult to carry out, and therefore can become problematic.

It is precisely because synthetic vitamins must be converted in the body to coenzyme forms that manufacturers are increasingly producing stabilized forms of the active coenzyme vitamins.

My vitamins are real food technology. Is that what you mean?
