Remember Hg toxic folks need adrenal *cortex* extract, they rarely tolerate the entire adrenal glandular like Nutricology.
Folks like me who have high Cd might benefit from nutricology. Even I only take a half a capsule of it.
Also Cutler mentions other possible adrenal supplements--pregnenolone, licorice, HC cream, forskolin (probably too stimulating for you if you don't tolerate Nutricology), more in the yahoo frequent dose chelation group and cutler's books.
Hg really hits adrenal system very hard. It is so important to support it or members find that they can't tolerate decent doses of chelators.
