 After taking Theragram Vitamins for ten years, I called the company due to
flare ups. They advised me that there is an inactive ingredient that is
simular to wheat. If wheat is a problem then I should discontinue taking
them. I was told about Centrum by another Celiac and that's what I use now.
Respectfully  Feeling a little better.
