Ancient Purity Presents N-acetyl-cysteine (NAC). A highly stable and bioavailable amino acid that is essential for producing glutathione, the body's primary antioxidant. Amino acids are necessary building blocks for forming proteins, which help in tissue repair, maintenance, and growth. NAC has a reputation for refilling glutathione levels in the body, providing protection against oxidative stress and damage caused by free radicals to maintain healthy cells. L-Cysteine, which is rich in high-protein foods, is necessary for the production of Glutathione. However, a restricted diet may cause a shortage of protein, reducing the ability to synthesis Glutathione. NAC also plays a crucial role in the detoxification system, supporting respiratory and circulation processes, and regulating levels of the essential neurotransmitter, Glutamate in the brain. L-Cysteine promotes healthy skin, hair, and nails by stimulating keratin synthesis, but levels may decrease during times of prolonged stress, low immunity, or insufficient protein intake. Increasing age can also slow down the synthesis of Cysteine and Glutathione, making it necessary to supplement with NAC. Research has found that when combined with other vitamins and essential fatty acids, NAC can decrease levels of reactive oxygen species (ROS) and increase the chances of successful pregnancy, particularly for women with PCOS. High levels of N-Acetyl-Carnitine are also found in the male reproductive system. N-Acetyl-Cysteine is rich in a strong sulphur-like odour, which is entirely normal. Each capsule comprises 500mg of pure NAC.
