    B vitamins in the best forms (such as the active, natural form of folate vs. artificial folic acid), plus L-theanine which has good benefits for stress. Overall a good combination for helping to handle stress on the body. (I took nutrition in university and worked in a health food store for over 10 years so I am very familiar with supplements).

    The product is great -- with 7 types of magnesium it takes care of all needs. I'm a bit concerned however that when I buy two instead of just one, I get charged extra duty ... that has made me look for other options that might work for us.
