Multivitamins
I rarely take a multivitamin, just when I have been having a poor diet for multiple days. Dosage: It is unclear whether to take one or not. If you eat a good diet with fruits and vegetables, it is probably unnecessary, and may be harmful. If you do take one, be especially cautious about high doses of fat-soluble vitamins and minerals. They can be hazardous, especially if you eat a good diet. Unfortunately, good studies are lacking. When I was taken to dinner by the industry leaders of probably the leading brand of vitamin, they only knew of studies on starving people in China who showed benefit from a multivitamin. I explained the hazard of having 100% of the daily value of iron in their supplements, and they soon removed iron from everything but younger women’s multivitamins.
Other reasons to take a multivitamin- While about 50% of people, including nutrition researchers at LPI, take a multivitamin, no one has told me why.
