poisonResearch appearing in the American Journal of Clinical Nutrition (October 2007, Volume 86) shows that folic acid may help to reduce blood arsenic levels. Folic is from the word “foliage” because it is a nutrient that is found in fresh produce. The double-blind, placebo-controlled research looked at 130 people who had been exposed to arsenic. They were divided into two groups and given either 400 mcg/day of folic acid or a placebo. After 12 weeks of supplementation, the group receiving the folic acid had reduced arsenic levels by 13.6%, compared to 2.5% in the placebo group.
