BCAA Pro (300 tablets)

BCAA Pro (300 tablets) by Yamamoto Nutrition is a dietary supplement that provides 5 g of branched-chain amino acids per serving, in the classic 2:1:1 ratio of leucine, isoleucine, and valine. Its tablet form is particularly convenient if you want to incorporate BCAAs into your workout routine without having to prepare a shaker.

Each serving of 5 tablets provides 2,500 mg of L-leucine, 1,250 mg of L-isoleucine, and 1,250 mg of L-valine—for a total of 5 g of BCAAs. These three amino acids are essential amino acids: your body cannot produce them in sufficient quantities, so they must be obtained through your diet.

The formula also stands out for the source of its amino acids, which are obtained through plant fermentation. These are Kyowa Quality® BCAAs, a raw material known for its high purity. BCAA Pro also provides vitamin B1 and vitamin B6.

Each serving provides 0.33 mg of vitamin B1, or 30% of the NRVs, which contributes to normal energy metabolism. The formula also provides 0.6 mg of vitamin B6, or about 43% of the NRV: this contributes to normal protein and glycogen metabolism and also helps reduce fatigue.
