Key ingredients 9

L-lysine acetate
Very Good

L-lysine acetate is an essential amino acid important for protein synthesis and muscle repair. It is often used in supplements to support athletic performance and recovery. As an essential amino acid, it must be obtained through diet or supplementation.

Benefits

Supports muscle repair and growth, and is crucial for collagen formation.

L-leucine
Very Good

L-leucine is a branched-chain amino acid (BCAA) that plays a critical role in muscle protein synthesis. It is highly valued in sports nutrition for its ability to stimulate muscle growth and recovery. As a BCAA, it is metabolized directly in the muscles, providing quick energy.

Benefits

Promotes muscle growth and aids in recovery after exercise.

L-phenylalanine
Very Good

L-phenylalanine is an essential amino acid that is a precursor to neurotransmitters like dopamine and norepinephrine. It plays a role in mood regulation and cognitive function. This amino acid is crucial for the production of other important molecules in the body.

Benefits

Supports neurotransmitter production and cognitive function.

L-threonine
Very Good

L-threonine is an essential amino acid necessary for protein synthesis and the production of collagen and elastin. It supports immune function and liver health. As an essential amino acid, it must be obtained through diet or supplementation.

Benefits

Supports immune function and is crucial for collagen production.

L-histidine
Very Good

L-histidine is an essential amino acid important for growth and tissue repair. It is a precursor to histamine, which plays a role in immune response and digestion. This amino acid is also involved in the production of red and white blood cells.

Benefits

Supports immune function and is crucial for blood cell production.

L-methionine
Very Good

L-methionine is an essential amino acid that plays a role in metabolism and detoxification. It is a precursor to cysteine and taurine, which are important for liver health and antioxidant defense. This amino acid is also involved in the synthesis of proteins and other important molecules.

Benefits

Supports liver health and antioxidant defense.

L-tryptophan
Very Good

L-tryptophan is an essential amino acid that is a precursor to serotonin, a neurotransmitter that regulates mood and sleep. It is important for protein synthesis and overall mental health. This amino acid is often used in supplements to support mood and relaxation.

Benefits

Supports mood regulation and sleep quality.
