I like this brand Thorne Amino Complex, no added sugars or preservative, great during and after workout, love the lemon taste!
I have been using Thorne Amino Complex for a few years. I take it like a medicine. What I notice most is that when I run out and go a few days without it before my order comes in, my memory declines.
Mixes easy and pleasant tasting. However unsure if effective.
great pre-post workout drink.
