Second of all, they aren't regulated by the FDA. So who knows what you are even swallowing (hint, probably rat poop and arsenic).
Three new studies published in the Annals of Internal Medicine add yet more data to the mountain of evidence that most people get all the vitamins and minerals they need from food.
The Food and Drug Administration doesn't regulate dietary supplements as drugs — they aren't tested for safety and efficacy before they’re sold. Many aren't made according to minimal standards of manufacturing (the F.D.A. has even found some of the facilities where supplements are made to be contaminated with rodent feces and urine). And many are mislabeled, accidentally or intentionally. They often aren't what they say they are. For example: In 2003, researchers tested “ayurvedic” remedies from health food stores throughout Boston. They found that 20 percent contained potentially harmful levels of lead, mercury or arsenic.Third, their is mounting evidence that mega vitamins are really bad for you. Like cancer, heart disease, early death bad.
You may have heard the term "antioxidant" as a buzzword that applies to some vitamins. Antioxidants combat free radicals -- molecules produced when your body breaks down food, or by environmental exposures like tobacco smoke and radiation, according to the National Institutes of Health. Free radicals damage cell membranes and DNA.
Doctors recommend a healthy intake of fruits and vegetables containing antioxidants to prevent this from happening and apparently decreasing the risk of conditions such as cancer and heart disease.
However, oxidation is necessary for life, and preventing too much of this process can be a bad thing because cells that need to be destroyed, such as cancer cells, won't be.If you are pregnant/nursing/trying to become pregnant or have a diagnosed vitamin deficiency and/or your doctor (who is a legitimate doctor and not just some fraud who is trying to sell you stuff that s/he profits off of) prescribes vitamins, then by all means. Take the vitamins. But taking vitamins for no other reason? Not really a good idea. Eat your fruits and veggies and skip the expensive pee. That stuff could be filled with lead, mercury, arsenic, and carcinogens. Save your money. Spend it in the produce section. And skip that elective B12 shot. (Ahem, MOM.)
