Nutricost® L-Cysteine 500 mg, 120 capsules

L-Cysteine is an amino acid that supports the normal condition of the cardiovascular system and liver. It enhances the body's detoxification process and liver function through the action of L-cysteine, which is necessary for the synthesis of glutathione and other biologically active compounds.

• Supports the liver's natural detoxification properties
• Helps maintain the elasticity and tone of blood vessels
• Supports the synthesis of glutathione – a key intracellular antioxidant
• Suitable for situations with increased stress on the liver
• Maintains healthy skin, hair, and nails through keratin synthesis

Active ingredient

L-cysteine is a conditionally essential amino acid, which means that under certain conditions (e.g., stress, illness, intense physical activity), the human body cannot produce it in sufficient amounts and it must be supplemented. Cysteine is involved in the synthesis of glutathione, a tripeptide with strong antioxidant activity. L-cysteine is also linked to the biosynthesis of taurine, coenzyme A, and other vital compounds.

Biochemical significance and physiological benefits of L-cysteine

Its involvement in glutathione synthesis is one of the most important roles of L-cysteine. Glutathione plays a crucial role in maintaining redox balance in cells, acting as an antioxidant and enzymatic cofactor. Without sufficient cysteine, glutathione synthesis is limited and protection against oxidative stress is weakened.

Support for liver detoxification

The liver is the main organ responsible for the transformation and elimination of toxic compounds. L-cysteine supports the liver's detoxification phases by participating in the formation of sulfur-containing congeners and restoring the antioxidant capacity of liver cells.

Maintaining cardiovascular function

This amino acid is also involved in the regulation of homocysteine, which at elevated levels is associated with an increased risk of atherosclerosis and vascular events.
