Natural Factors Stress B Formula

Posted by Reviewer1068187 on Feb 26, 2008

I have enjoyed this formula for eight years now, and I find that it is a very strong formula. I feel like I am taking my B and C vitamins, when I take it. I have more confidence with it than other formulas, becauase I feel other formulas weak.
