Essential Amino Acids (EAAs) are the nine amino acids your body cannot produce on its own, meaning you can only get them through food or supplementation. They are the building blocks of protein and play a direct role in promoting muscle growth and repair. If you're training regularly and not getting enough EAAs through your diet (from sources like meat, eggs, or dairy), a supplement like Reflex Nutrition EAA is an efficient and convenient way to close that gap.

Each serving of Reflex Nutrition EAA delivers 16g of all nine essential amino acids. This includes three branched-chain amino acids (BCAAs), L-Leucine, L-Isoleucine, and L-Valine, plus six additional EAAs: L-Lysine, L-Phenylalanine, L-Threonine, L-Histidine, L-Methionine, and L-Tryptophan.

BCAAs (Branched-Chain Amino Acids) are a subset of EAAs. While BCAAs are well-studied for reducing muscle soreness after resistance training, they only cover three of the nine essential amino acids. EAA supplements like Reflex Nutrition EAA provide all nine, offering broader support for muscle growth, lean body mass, and reducing fatigue during training. For most people who train, a full-spectrum EAA product is the more complete option.

Reflex Nutrition recommends consuming EAA during your workout. This intra-workout timing is supported by research showing EAAs can help prevent muscle fatigue during resistance training sessions. Mix 25g (two level scoops) with 500ml of water and sip throughout your session. You can take up to two servings per day.
