<<Disclaimer: Verify this information before applying it to your situation.>> Has anyone heard of Twin Labs? They manufacture vitamins and I was wondering if anyone had any experience with them. Seems anything I take in the way of vitamins upset my stomach so am trying to find a gf source. I am also curious to know if any of you find that vitamins do help. I learned something today at the health food store that I didnt know and thought I'd pass it on. The guy there was telling me that cellulose can contain gluten, came as a surprise to me.
