BCAA Supplement?

Benefits, Risks

BCAAs, also known as “branch-chain

amino acids” are three essential

amino acids (1) leucine, (2)

isoleucine, and (3) valine, each of

which has unique properties.

Amino acids are the building blocks of

protein; they are chemical

compounds that, when linked

together, form proteins. When protein

is ingested, our bodies break it down

into amino acids before it’s absorbed

into the bloodstream and used by the

body.

WHAT IS BCCA?

BCAA supplements are important is because they are

the only amino acids which are not metabolized by the

liver, making them directly available to muscle tissues,

where they act in a number of positive ways.

BCAAs combat age-related decreases in muscle

mass. The process by which they accomplish this task

is outlined in the first entry of this list. Still, its

implication in the elderly warrants repeating.

BCAA Supplement Benefits

BCAAs enhance protein synthesis. There is a gene

in muscle cells called mTOR which essentially “turns

on” muscle protein synthesis. Ingestion of BCAAs,

particularly leucine, activates this pathway and leads to

increased muscle protein formation.

BCAAs support fat loss. There have been a number

of studies which show BCAA intake correlates to

decreased obesity rates. One large study examined

over 4000 people and found that those with the highest

intake of BCAAs had the lowest bodyweights

BCAAs lessen the loss of lean body mass. BCAAs

are well-known to be anti-catabolic, and this is

especially important to anyone who is trying to lose

body fat, as lean mass loss is a very real risk when a

person is in a calorie-restricted state.

BCAAs may offer other beneficial effects. BCAAs

might enhance brain function, contribute to a more

positive mood, and help regulate blood sugar.
