If you pride yourself in taking your vitamin supplement religiously then a new study could have you a bit worried.
According to a recent study by the University of Colorado, over-the-counter multivitamins do "more harm than good." and can increase your risk of developing heart disease and cancer.
The University of Colorado study revealed after reviewing several trials which involved thousands of patients, over the course of about ten years that taking vitamin and mineral supplements substantially increases your chances of developing health problems.
Beta carotene which has been marketed and advertised to boost the immune system has actually been shown to increase lung cancer risk by 20 percent, when more than the recommended dosage is consumed.
Folic acid is commonly thought to reduce precancerous polyps in the colon actually increased to number of precancerous polyps in the trial group, when compared to the placebo.
The associate director for cancer prevention at the university's cancer center, Prof Tim Byers said: “We have discovered that taking extra vitamins and minerals do more harm than good. We found that the supplements were actually not beneficial for their health. In fact, some people actually got more cancer while on the vitamins.”
The vitamin supplement industry is worth a whopping 27 billion dollars in America alone and these products frequently boast about their product containing more than the recommended daily allowance of vitamins and minerals.
According to Byers, there is "no substitute for good, nutritional food," and he urges against taking more than the recommended dose. With half of all Americans taking vitamin supplements according to a Gallup Poll this could be bad news, not only for the supplement industry, but also for consumers. It's better to get your vitamins and minerals from a healthy diet full of fresh fruits and vegetables and not from supplements.
Initially when supplements where tested on animals they showed very promising results, but this study on humans failed to reveal the same findings in the long-term studies. “We are not sure why this is happening at the molecular level but evidence shows that people who take more dietary supplements than needed tend to have a higher risk of developing cancer,” he said.
Byers also said his study revealed that there are public health issues with supplements and he urges authorities to “pay more attention to safety and how they are advertised”.
After learning about this study, I hastily went to the cupboard to look at the percentages of beta carotene, folic acid and other vitamins contained in my supplements, only to find that my beta carotene has a whopping 300% of the recommended daily allowance(RDA) and 200% RDA of folic acid...yikes.
I believe from now on I'll stick with the natural way to get my vitamins and minerals.
