That 220mg zinc sulfate is really hard to take. This is the typical product doctors use in nursing homes. It is brutal, and really causes alot of vomiting.

The best zinc for bipolars would be zinc monomethionine. This is called OptiZinc and made by Source Naturals. www.iherb.com has it very reasonably in price.

Zinc picolinate is also easier to tolerate, but picolinic acid has some negative effects in bipolars so I would not recommend it here for this board. For others, yes.

Make sure your magnesium is NOT oxide form. This is very poorly absorbed and basically useless. You can learn more about that on my magnesium thread at the vitamin forum.
And remember too, elemental vs combined salt weight on your labels.
For example the 220mg zinc sulfate is NOT 220mg of ZINC. It is much less.

At my CE seminar last week, they recommended some vitamin E to prevent Alzheimer's. Up to 400 IU of d-alpha tocopherol (not the dl-form) was listed most recently.

Folic acid also works against depression. It is always a good idea to take it as a supplement, since much of it is destroyed in cooking. Do not exceed 800mcg per day without knowing your B12 status. B12 deficiency and too high folate lead to nerve damage.
