Basic research has shown that antioxidants such as vitamins C and E may prevent plaque buildup and protect health of the arteries. This has led, in part, to the development of a the multi-billion dollar “supplement” industry. This is an industry that is not regulated by the FDA, yet consumers purchase approximately $13 billion dollars worth of supplements each year. Naturally, researchers are interested in whether the claims play out. Evidence released from two very large studies today would suggest they do not.
A study on breast cancer, published in the Journal of the National Cancer Institute, looked at whether taking a supplement to raise calcium and vitamin D would help prevent hip fractures or breast cancer. Their study encompassed over 36,000 women, and over a seven year period they found no effect on breast cancer rates. The second study was for adult men taking vitamin E and vitamin C. Participants were followed for eight years, with researchers looking at rates of heart attack, stroke, and heart disease. They found no evidence of benefit in this group, either.
To be honest, I take a daily multi-vitamin. although I’m not very dedicated about it. But I do try. I can’t say I believe I feel better or worse on the days I remember to swallow my pill I would daresay that the majority of people I know take one. I also know people who are completely obsessed with supplements, and even go so far as to say that drug companies try to suppress supplements because they would hurt profits. These are the extremes. To be fair to most of my supplement taking friends, they are convinced that these supplements help them feel better. If they work, then by all means, continue to take them.
We should look honestly at the results of these studies though. At least one of these studies was partially funded by BASF, a maker of supplements. It’s not every day you’ll find a research study that indicts the product made by the company that funded the study. Most companies are out to promote their products. As my inner skeptic kicks in, I’ve started trying to be less reliant on vitamins, by getting more vitamins from food sources. It takes some thoughtful consideration, and willingness to try new foods. For instance, my recent backyard garden experiments will allow me to see how rose hips benefits my overall health.
I take lutein for long-term eye health. I take acetyl/L-carnitine for cellular function; I take an immune-balance supplement–EpiCor– which has absoloutely rid me of allergy symptoms and so far I’ve evaded serious cold/flu episodes. I used to take a multi, but not anymore. I think my diet gives me enough macro nutrients. Extra Vit. D has now almost reached consensus among researchers. We need much more than we’re getting now.
