Branched Chain Amino Acids (BCAA)

NOW Sports Branched Chain Amino Acids


As you exercise, your body burns mostly carbohydrates for energy. Once you’ve used your limited carbohydrate stores, what’s next on the energy menu? Muscle tissue. Your body will begin to break it down to utilize the amino acids contained within as an alternative energy source. Not good.

If you’re not providing your body with the raw material sufficient to meet its energy expenditure and its needs to build and repair muscle tissue, your body will break down your muscle tissue to produce energy. The result is that you’re actually losing muscle instead of gaining it - probably not the reason you’re working out, huh?

The key is to ensure that your body is synthesizing more protein than it’s taking from your muscles; then you will gain lean muscle mass instead of losing it.

This is where BCAAs save the day (and your physique).

  • The BCAAs, Isoleucine, Leucine, and Valine, are essential amino acids that can only be obtained from the diet.
  • They’re ridiculously awesome at stimulating protein synthesis, as well as optimizing your cell’s capacity to synthesize protein.
  • Better yet, they also help to reduce protein breakdown through several mechanisms of action. Sweet!

NOW® Sports Branched-Chain Amino Acid products are carefully screened for purity and potency and are manufactured with our industry-leading quality assurance procedures. And we always use the natural “L” form amino acids, because we believe that natural is better.
