Helps microscopic colitis
Made a positive difference in my gut and I have microscopic colitis. Better than cholestyramine. Noticed improvement after about a week using. I've continued using daily and no issues. Happy customer

NOT a Vine Voice Review
I've been taking L-Glutamine for a few weeks now after reading research done in relation to ADHD and ADD, in which individuals with ADHD had low Glutamine levels. Once supplemented, it helps a lot of said issues. Please do your own research regarding this, but for me- it's been an incredible supplement I will continue to buy. With that said, regarding the nature of Sports Research's L-Glutamine, I have found the powder to have a premium consistancy to it in comparison to others, which does not surprise me as I also take their D3+K2 Supplement (though it's a way better deal at Costco, and if you are reading this SR, please give us a better deal here on that via amazon!) and SR's fish oil, and those supplements have been top tier in regards to not only my own experience but from what I have read as well. This quality powder packs a punch in potency, and although I wouldn't recommend drinking it plain, it does mix well with straight water or any liquid. I mix it in with whatever I can, but know that if you do drink it with plain water, the taste is not good, and a little sour, but the effects are worth it. One last note, why take the powder vs pills? From the research I have gathered it is normal to take L-glutamine in higher dosages such as a full scoop (scoop included here!) and serving size indicate on the bottle. Pills on the other hand... not only is it a lot of capsules, it would be on the more expensive side. Grab this, potent, and mixes easily!

L-Glutamine for gut support
It’s definitely a lot for the amount you pay. I bought this mainly for gut support so I think it’s a little too early to tell if the advertised health benefits are working after a couple tries, but the powder dilutes well in any liquid. Taste is okay and looking at the ingredients, it’s a single-ingredient product so that’s reassuring. I’ve used other Sports Research vitamins before and quality is always top notch so I’m confident this will deliver as well.
