If someone is healthy not taking supplements and eating balanced meals is an excellent health strategy. There are lots of pitfalls with supplements. The worst way to take supplements is to follow the scientific evidence but disregard fails in clinical trials. If there is lots of scientific research in an area but clinical trials have not panned out there are very serious unknown factors that make such a strategy a dangerous strategy. Take for example, antioxidants. There is tons of scientific evidence that oxidant stress is a major difficulty in many illnesses but clinical trials of antioxidants have not shown supplemental free antioxidants to be useful in the treatment of chronic illnesses. Antioxidants should work but don’t work adds up to don’t try at home what has been shown to be a fail in clinics. Supplemental folic acid can be dangerous. Folic acid is another supplement that should work but clinical trials have not shown supplemental folic acid to be helpful where there are high homocysteine levels though, of course, women should take folic acid as MDs recommend to prevent neural tube defects in babies. My ideas adhere to scientific evidence, however, my ideas have not been clinically proven wrong.
