A very good option, it delivers what the brand promises and the fact that it's unflavored allows you to add it to any juice or smoothie.*

I advice this brand to everyone, they have long scoops that would help you till the end of the product. Some brands make short handled scoops so it is a pain when you reach the low levels of product, hard to reach the bottom of the can*

I've been incorporating this glutamine supplement into my daily routine for some time now, and it has proven to be a valuable addition to my fitness and wellness regimen. Glutamine is known for its role in muscle recovery, immune system support, and digestive health, and this product seems to deliver on those promises.*

I was having stomach issues with IBS and a friend informed me that if I take Glutamine it may help, Well it only took about 3 days @ 2 times a day and I seem to not be having any issues with my IBS, so now I only use the Glutamine and have stopped taking the prednisone tablets that I've used for the last 4 years.*
