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.

iHerb Customer Reviews

Excellent product!!

Posted by iHerb Customer on Oct 16, 2017 | Verified Purchase

love this one, but please keep it away from anyone with a "white powder" based drug habit, I'm serious. It's fantastic having it in powder form, take it after excercising and it's terrific. But again, hide this product very well from anyone with a drug habit.

Thanks for your feedback!

Excellent For Energy And Immune System

Posted by iHerb Customer on Jul 22, 2017 | Verified Purchase

My work in the theatre is high stress and high physical activity and I (and some other actors) always get struck down with the flu about three weeks into rehearsals. I guess I have a bit of an adrenal fatigue issue too. So I just got sick again and thought, nothing to lose I'm just going to try this out. I took half a teaspoon in some water morning and night. I got over this flu (granted with help from Chinese medicine) in 4 days while having to rehearse every day that I was sick! This is half the recovery time of what I'm used to! the side benefit is that in rehearsal I have more energy for longer and i don't feel as fatigued or hungry nearing the meal break, I also feel like I can think clearer, feel mentally sharper in the morning and feel more rested when I get up. Crazy thing is, I don't even need a big cup of coffee to wake up, and I'm really not a morning person! this a gonna be a work staple now!

Really Does Work But Have To Be Patient

Posted by iHerb Customer on Jul 03, 2017 | Verified Purchase

I bought the smaller size as I want to try it but now I'm ordering two large tubs. It doesn't has any bad flavor, actually has no flavor at all. It mixes really well and it works effectively, if taken on empty stomach in the morning. If you pair it with effervescent vitamin C, then you'll have your super energy booster ready in your hand at anytime. The results can be seen within 1.5 - 2 weeks, if taken consistently, about 1 - 2 tsp per day.

Thanks for your feedback!

Great for energy

Posted by iHerb Customer 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.
