My brother has been taking these for years. He says his skin is great because of the Nano Vit.
Oh, and he recently had stomach/intestinal surgery.
I began the nano Lifepak about three weeks ago and over the past few days my stomach... intestines are churning and get quite painful jabs.
My skin so far is no better as far as I can tell but that may take time.
As people are mentioning skin problems starting after taking these vitamins, why not do as I am going to do and that is get off them for a week or two and see what happens.
Trust your intuition as no one else can do that for you.
