Review
The Glutamic Acid with Pepsin works wonderful for me. I was having gallbladder pain and digestion issues. After reading a book about the symptoms I was experiencing I asked my alternative med. doctor if I could have issues with low stomach acid. Betaine HCL did not work for me so he suggested Glutamic Acid. It has made the difference for me between pain and no pain. (i also avoid eggs) Thank you Seacoast for making this product!!!

A growing body of evidence suggests that during certain stressful times, the body may require more glutamine than it can produce. Under these circumstances glutamine may be considered a "conditionally essential" amino acid. Glutamine is involved in maintaining a positive nitrogen balance (an anabolic state) and also aids rapidly growing cells (immune system lymphocytes and intestinal cell enterocytes). In addition, glutamine isa regulator of acid-base balance and a nitrogen transporter.* NOW L-Glutamine Powder is a 100% pure, free-form, non-essential, amino acid and is the highest grade available.
