It is classed as an essential amino acid and cannot be synthesized by the body itself. This means that a sufficient supply of methionine in the diet or as a dietary supplement is of particular importance.
It is sometimes counted as a semi-essential amino acid due to its role as a catalyst in many important metabolic cycles. L-cysteine supports the synthesis of the highly antioxidative Glutathione boosts the immune system and inhibits inflammation.
It is classed as a semi-essential amino acid. Arginine is involved in many metabolic processes and important in the treatment of heart diseases and high blood pressure.
At 60%, it represents the largest amount of free amino acids in the body. The demand for glutamine increases with physical and mental stress. Production of this important amino acid, which takes place in the body, often slows down with age and does not generate sufficient amounts. External supplementation is recommended in such cases. Environmental factors such as stress or extreme physical strain will also lead to an increased demand in Cysteine. It therefore plays an important part in detoxification and the resulting protection of several tissues and organs.
Sufficient supply of glutamine is important for firm and supple skin. If not enough glutamine is available, the body takes the necessary protein from muscle mass and converts it to glutamine and energy. This leads to muscle proteins being lost, muscle strands becoming thinner and the skin becoming generally saggy. This is why glutamine has been referred to as an “internal fountain of youth” by scientists.
