Love this. Can only taste a slight flavor in certain drinks but it’s 99% flavorless. Mixes in like a dream. My only complaint is how aggressively long the scoop handle is. When the container is new you have to really bury it in there in order to close the top. Easy to find though!

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.

I have been using NutraBio products almost from when they started. I workout 5 x per week and take my nutrition seriously. Unfortunately NutraBio has raised their prices without any regard to their loyal customer base. Im out!

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

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.

This L Glutamine did not dissolve well at all, you have to put it in something thick to mask it. Tried cold and hot beverages and still won’t dissolve while mixing with a heavy duty milk frother or a shaker cup. It also is not tasteless with a cold/hot beverage. I wish the was a returnable item on Amazon because I would’ve sent it back after the first use.

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!!!

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.

Ordered this product for my daughter. Her nutritionist recommended it to help her get through chemo. Seems to be just what she needed.

I love this glutamine powder. Nutrabio sells pharmaceutical grade products without fillers. I take this for a variety of reasons, but it is great in preventing muscle pain after a work out. I take one scoop daily when I remember to help prevent leaky gut and it is supposed to help with energy (although I have not found any benefit there in the energy department). But the best use for me is preventing muscle pain when working out or doing heavy yard work. For best results, take a scoop before your workout, another scoop afterwards and again before bed and it does a very good job at preventing muscle pain. My friend used it before and after running a marathon and was amazed at the difference. She said normally after a marathon she is spent, but with the l glutamine (she uses a different brand) she was able to go home and mow her lawn and give her dogs a bath. The benefit of ordering from the amazon marketplace, is you can usually get free shipping.
