MET-Rx BCAAs are the building blocks of protein – of special importance to body builders and power

athletes. BCAAs L-leucine, L-isoleucine and L-valine make up about one third of the total protein

content of human muscle tissue.

Increase muscle strength and growth

Around 33% of muscle protein consists of BCAAs. Even

moderate exercise causes levels of BCAAs to drop rapidly

– resulting in muscle tissue breakdown (catabolism), fatigue

and a drop in testosterone levels. Research shows that

athletes who supplement with BCAAs experience increased

muscle growth and strength, overall increases in energy

and improved muscle power output.

Increased recovery

Perhaps the greatest benefit to hard training athletes is the

increase in metabolic recovery that follows supplementation.

Most athletes feel a substantial decrease in the amount of

post-exercise muscle soreness soon after beginning BCAA

supplementation. This means faster recovery from

exercise-induced protein damage (remember your muscles

grow when you damage them), which in turn means faster

size and strength gains. With increased recovery you can

hit the iron harder and more frequently – and thus meet

your goals sooner.

Boosting immune function

When you train at high intensity or high volume you risk

immune suppression and infections. If you\'re sick it\'s hard

to train, much less grow. It\'s even harder to come back

after an illness without losing a ton of strength and size. By

supplementing with BCAAs you\'ll help reverse glutamine

loss, which is essential for immune function. BCAAs also

help prevent a catabolic state in the body, which in turn can

help improve recovery and lessen the damaging effects

your exercise sessions may have on the body.
