Selenium and molybdenum are highly recommended for mercury toxic people. In addition, high doses of vitamin C, e.g. 1000 mgs. 5x day. Vitamin C helps to counteract the damage that mercury does to us. Some mercury toxic people tend to retain copper, thus copper supplementation is not recommended. It should be avoided. I know it's cheaper to take multis, however, for us, I think that individual minerals and vitamins are better, especially where we can control doses and take as much as we need. For example, a lot more molybdenum and vitamin C are recommended than you will find in a multi. I take a liquid molybdenum myself (better absorption). It comes with a dropper and I just take it all day long. Also, I buy liquid B vitamins as I prefer them for better absorption since I have gut problems. The B complex is also important with mercury toxicity. I would avoid copper if I were you.
