Essential amino acids (EAAs) are vital for numerous body functions, from muscle growth to neurotransmitter synthesis. The nine EAAs—L-Leucine, L-Lysine, L-Threonine, L-Valine, L-Isoleucine, L-Phenylalanine, L-Histidine, L-Tryptophan, and L-Methionine—are the building blocks the body cannot produce on its own and must obtain through diet. This supplement offers all nine in a balanced blend, making it an easy and effective way to ensure you’re meeting your daily needs.
These amino acids play an essential role in protein synthesis, muscle recovery, and maintaining optimal bodily functions like metabolism and cognitive health. With a high concentration of branched-chain amino acids (BCAAs), it helps enhance endurance, reduce muscle soreness, and accelerate recovery after intense workouts. For those focused on fitness, it is a must-have for supporting muscle growth and maintaining lean muscle mass. It’s soy-free, gluten-free, and non-GMO, making it suitable for a range of dietary preferences.
