Unflavored is better you can mix with anything.

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!

I know friends who have used this with great success. I’m one of the rare few who had a terrible reaction. Now I have half or more of this product going to waste. I tried to push through by tapering up and down, but the headaches and extreme fatigue was too much. I’ve heard reactions are rare but after this I noticed the same reaction to bone broth which both realizations all around are a bummer because I really wanted this to help repair my gut. Which, in fairness it did help a little but the headaches were just too much.

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

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!!!

NutraBio = “Cheap” Price … for HIGH QUALITY products

Excellent product for the price. Clean energy throughout the day@

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.

I had gotten extremely sick from Nobi Night Time Sleep Burner herbal pills. They tore up my intestines. I could barely eat and I had severe pain. I tried many different natural remedies that didnt help. But then I read about L-Glutamine, that it helps heal intestines and stomach. I already had this NutraBio L-Glutamine Powder for bodybuilding, but wast using it often. I read that 30 grams per day of Glutamine is safe and effective for healing of intestines and for IBS. So I started using NutraBio L-Glutamine Powder at 30 grams per day and got much better quickly! I really feel that I would have had to go to the hospital for surgery if it had not been for this awesome product. Now, I got to start working out too!

Yes this did help with my bloating, & gut issues BUT I had to stop taking this. After a couple weeks I started having headaches every day. I took only one scoop with my coffee every morning, it is tasteless. This was the only new thing I added to my regime. After about 3 days my headaches finally subsided. It may work for you! But Im prone to headaches so be careful.
