Nutrimuscle 's BCAA 4.1.1 (300g) is a powdered dietary supplement that combines the three essential branched-chain amino acids: L-leucine, L-isoleucine, and L-valine. They are combined in a specific 4:1:1 ratio, with four times as much leucine as isoleucine and valine.

In the Natural flavor, each 6 g serving provides 4,000 mg of L-leucine, 1,000 mg of L-isoleucine, and 1,000 mg of L-valine—for a total of 6 g of pure BCAAs. This high concentration of leucine sets the formula apart from traditional BCAAs with a 2:1:1 ratio and makes it particularly beneficial for supporting a routine focused on muscle gain and recovery around workouts.

BCAAs are essential amino acids: your body cannot produce them on its own and must obtain them through your diet. This formula makes it easy to supplement your intake before, during, or after your workout, especially if you do weight training, bodybuilding, powerlifting, cross-training, Hyrox, or combat sports. The three amino acids used are derived from plant-based fermentation.

The formula is therefore suitable for vegan and vegetarian diets. The Plain version keeps it simple with only L-leucine, L-isoleucine, and L-valine, without any flavoring or sweeteners. To make it more enjoyable to consume during your workout, the product is also available in Blueberry, Passion Fruit, Cola, Yuzu, and Blueberry flavors.

These recipes combine BCAAs with natural flavors, citric acid, and sucralose. This allows you to prepare a fruity drink to sip on during your workout instead of just drinking water.
