ISO-AMINO has quickly become known as the best BCAA supplement on the market due to its simple formula and out of this world taste! ISO-AMINO features 5 grams of instantized BCAAs in a research validated 2:1:1 ratio. Pure BCAAs are everything you need to build, repair and trigger lean muscle growth. ISO-AMINO is a throwback to the old school BCAAs that are just that…. pure BCAAs. No added marketing fluff, proprietary blends or under dosed “everything & the kitchen sink” formulas that only cushion the manufacturers wallet.
CLINICALLY PROVEN BCAA RATIO! BCAA amino acids in a 2:1:1 ratio have been clinically studied and PROVEN to effectively aid in muscle repair, growth, muscular energy and even fat loss. BCAA supplements are comprised of 3 branched chain amino acids – Leucine, Iso-Leucine and Valine. BCAA products with inflated ratios of 8:1:1 or even 10:1:1 show no added benefit over their 2:1:1 counterpart. ISO-AMINO stuck with the tried and true 2:1:1 ratio… “if it’s not broke, don’t fix it”.
CLEAN – NO ARTIFICIAL COLORS OR DYES. ISO-AMINO is as clean as possible, containing no artificial colors or dyes, almost mixes completely clear in water! This is something you’ll want to sip on all day. ISO-AMINO is a BCAA powder rather than BCAA capsule for enhanced absorption and utilization.
OUT OF THIS WORLD FLAVORS! It has nothing to do with science or efficacy, but it’s important to enjoy what you spent your hard earned money on. We take flavor and mixability very seriously. This is where ISO-AMINO stands as the clear leader. MAN Sports has made monumental advances in flavor systems to provide extremely unique, mouthwatering, one-of-a-kind flavors.
