Product Overview


  • Pharmaceutical Grade L-Glutamine
  • Supports Muscle Tissue & Immune Function
  • Dietary Supplement
  • Vegan

L-Glutamine - the most abundant amino acid in the human body - is involved in many metabolic processes, including the synthesis and protection of muscle tissue, the production of glycogen, as well as immune support during periods of immune and muscular stress. L-Glutamine is also a major source of fuel for enterocytes (intestinal cells) and hence supports the integrity of the intestinal lining.

Suggested Use

Mix ½ teaspoon (approximately 2 g) into 6 to 8 oz of fluid and drink when stomach is empty or as directed by your qualified healthcare professional. For athletes, maximal results will be obtained by supplementing with 2 g of glutamine after exercise.

Easy to take

Posted by 5422823878426687090 on Jan 21, 2017 | Verified Purchase

I am taking this product to heal a leaky gut. The taste was a bit difficult at first, but after a few days, it has become very easy. I take mine in a glass of water, twice a day and at least 1/2 hour before meals. Noticed a difference from the first day. Less bloating, fuzziness in head has diminished and feel stronger. Good product.

Thanks for your feedback!

Great for energy

Posted by Reviewer1630926 on Jan 17, 2017 | Verified Purchase

I saw in a show that a person with Chronic fatigue was given this and it helped her. So I tried it and it does help with my bad adrenal fatigue. It gives me more energy for about 3 - 4 hrs. However, after taking it for a year, I started to get stomach discomfort and felt unwell for a couple of hours. But other people don't have a problem. So, I had to wait months before I could take it again which it's a bit annoying (It happens with all brands). Hence, why I only take a tiny bit. If you don't get this problem you could probably take more of it. Try it if you suffer from fatigue.

Jarrow Formulas, L-Glutamine, 4 oz (113 g) Powder

Posted by feedMemore on Nov 05, 2016 | Verified Purchase

Life saver for my precious man. He is type of catabolic (metabolism) and it is very hard for him to gain normal, good looking weight. If he is stressed out, after some illness or other physical challenge, he is loosing 4-5 kilos and is looking miserably. Later he struggles so much to regain that kilos. This was diaster until we found out about glutamine. He tried BCAA prior to glutamine, but we think glutamine is better working thing for him. Now my man regained his lost kilos during illness in June, but I think only with the help of glutamine. Without it, it would be impossible or would take years probably. We have now high expectations for the future as we see such good results and effect. We think that prolonged use of such a wonderful product (works wonders on intestines, stomach as well) will make my man to really good looking, more normal man without that nasty catabolic effects. Maybe he won't turn to anabolic state as I am in, but we hope for normal type so much.

Thanks for your feedback!
