Bringing Old School Back

Pure BCAAs are everything you need to rebuild, repair and trigger lean muscle growth. ISO-Amino is a throwback to the old school BCAAs that are just that, pure isolated BCAAs. No added marketing fluff, prop blends or underdosed “everything & the kitchen-sink” formulas that only cushion the manufacturers wallet.

The Fat Burning, Muscle Building BCAA Ratio

BCAAs 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 products with inflated ratios of 8:1:1 or even 10:1:1 show no added benefit over their 2:1:1 counterpart. So why the 2:1:1 ratio of BCAAs? Simple, “if it’s not broke, don’t fix it.”

Baylor University Proves 2:1:1 Ratio

Scientists from Baylor University gave college-age men either a leucine supplement, a BCAA supplement or a placebo before and after a leg workout. They discovered that while leucine increased muscle protein synthesis after the workout better than the placebo did, the BCAAs increased protein synthesis even better than leucine and the placebo. That’s a big reason to stick to a 2:1:1 ratio when it comes to BCAA supplements.

An Amino That Tastes Good?

It has nothing to do with science or efficacy – but it’s important to enjoy what you spend your hard earned money on. We take flavor & 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, one-of-a-kind flavors.

ISO aminos

I drink one scoop as directed in a large 16 oz bottle. I have lost 7lbs. This product seems to really curb my appetite. I take it everyday even when not working out. I’m not sure if anyone else has experienced this, but it was unexpected and awesome!!!!

LOVE LOVE LOVE

The most used product in our household. Two scoops of pink lemon aid in my gallon of water every morning and I am good to go. My Boyfriend does the same.
All Man sports flavors just hit different than any other brand. I cant imagine not having it at this point. Just patiently waiting for them to apply the peach ring flavor to the ISO aminos.

I usually love every flavor of iso-aminos, but unfortunately the blue bombsicle is not one I can handle drinking. Jolly watermelon and sour batch are my absolute favorites!
