I bought this because my friend, a pro fitness bodybuilder, told me she used L Glutamine as part of her routine. This brand was highly rated on Amazon so I went with it. It has no taste and dissolves just fine. But, I kept reading up on it,and I'm pretty impressed. Aside from the body building stuff, it has other benefits. One, a lot of people with Celiac use this to repair their gut when they've been 'glutened." I'm not certain if it helps, but it doesn't hurt.
