I am over fifty years old and have taken vitamins all my life. I have tried virtually every brand of vitamins. Enzymatic Therapy For Men 50 Plus is without a doubt the best I have used. My system does not store vitamins the way it should and taking a daily dose split into four doses makes much more sense for me than taking a one a day that passes through my system quickly. By taking it four seperate times I get a constant boost to my system. My body absorbs this vitamin much better than all the others I have tried.
