Which vitamins should i take?

Supplements: In general i recommend a combination of a multivitamin/mineral an additional antioxidant and omega 3 oil. There are other supplements that can be added for specific benefits.

Vitamins: A good multivitamin is a good idea. It's like an insurance policy for when we don't eat right, don't sleep well, or are especially stressed. Go to a good store or get some guidance because the popular brands are typically very week and not helpful. You can take them as long as you wish. Spectracell labs in TX offers a good micronutrient test that provides specific info for your body.
