Gnarly Nutrition BCAAs: A dietary supplement geared especially for vegans, alpinists and older athletes
Mountain Standards Gear Review: Digital Editor Derek Franz has been using the Gnarly Nutrition Pre and BCAA (branched chain amino acid) dietary supplements for the past year. Though unable to definitively say how much of a difference, if any, the supplements have made for his fitness, he writes: “What I do know, is that my fitness has been on an upward roll lately, and Gnarly has been one of many ingredients along the way, so I can’t discount it.” As with most any dietary supplement, Franz notes, there can be serious side effects if they aren’t used properly. Four stars.
