NutraBio L-Glutamine Powder - Amino Acid - Pure Grade: Absolutely no Additives, Fillers or Excipients! - Muscle Recovery Supplement - (500 Grams)

Great product with great customer service.

I can taste something when I add this to water, which was what I read you should do. To offset, I add flavor to the water to cover up the taste of the L Glutamine. Time will tell if this actually helps heal my gut.

Ive been an avid user of glutamine for about 15 years. In combination with Ester-C, I strongly believe the combination is what has prevented me from being ill, and only having about a 3-day cold once every couple years. Cheaper priced glutamine is grainy and takes a long time to dissolve in water, if it will completely dissolve at all. The highest quality glutamine is so fine its almost like a powder and dissolves rather quickly in plain water. After reading the reviews, it sounded like Nutrabios glutamine was one of the higher grade glutamines and when I first tried it I was amazed at the quality of it! It is easily the highest quality or matches the highest quality glutamine I have used in the last 15 years. AND it is priced like the lower quality brands. BUY IT!!!

Within first 2 weeks I began to feel digestive relief. I have leaky gut syndrome and this has improved how I digest and eliminate food.

It is glutamine. Has an off flavor when. Mixed with a protein shake. Would not purchase this brand again.

NutraBio = “Cheap” Price … for HIGH QUALITY products

Has a slight taste that was not very good but the product seems to work.

So far, all I can address is the packaging, cost, and taste. Packaging is marked with an expiration date, which is helpful; powder settled so that the bottle appears half-full, but that seems reasonable; the taste is non-existent to me. It may have a slight, almost undetectable bitterness, but I think I could just eat it from a spoon and wash it down with water. The price is better than most, and this is purported to be pure product with no fillers. Who wants fillers? I have celiac (gluten sensitivity), so I am trying this for after Ive accidentally eaten gluten, which happens every couple of months. When it does, I have digestion issues, joint pain, irritability and muscle weakness. It takes a week or so to recover, so Im hoping this will shorten that time. I will update when I have results.

Im been using glutamine for years after working out and never had a problem with it. This brand seems to be high quality but I was supposed to work up to 4x a day to heal severe leaky gut and could barely tolerate 2-3 x without stomach pain. The higher dose also totally killed my appetite. I also had no cravings in the evening. For me this was a bad thing because I struggle to keep any weight on. I continued with it for several weeks along with some other supplements and when I was retested, my gut had showed significant improvement and the gut was almost back to normal! I have not been tested a third time to see if it is totally healed, but I feel along better than I did when I started. I have used several supplements from this company and am happy with the quality.

I have been dealing with gastritis due to gluten sensitivity for years and the damage cause to my gut lining has wreaked havoc on my body. Over time I have developed leaky gut and a bacterial overgrowth due to lack of stomach acid. In order to correct these issues I first had to clear the infection using various supplements while also trying to increase acidity with an HCL supplement. My gut lining was very irritated and damaged so it was in dire need of soothing and healing. This was done by a combination of slippery elm and L-glutamine. I have tried various brands of L-glutamine over the past few years and this brand is definitely the most effective one I have used with the highest quality. It has no flavor whatsoever and easily dissolves in water without settling at the bottom of the cup like most other brands that contain fillers and binders. I can feel the soothing effect in my gut within a few moments of drinking it. Unfortunately this supplement will be a staple in my diet for probably the rest of my life due to the fact that it is very hard to be 100% gluten free at all times with my busy lifestyle. Even the smallest amounts of gluten irritate my stomach but this stuff is like a band-aid with neosporin on it and really heals and soothes quickly. Plus its a great price for a quality product.
