Weight90 x 500mg Capsules

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. 500mg of NAC per capsule. Stored in a Miron Glass Jar.

Q: How long does it take for NAC to work?
The amount of time it takes for NAC to work varies depending on the individual, dosage, and the condition being treated. While it can take several months for certain conditions, it can be effective within hours when applying to the issue of overdoses and toxicity.

Q: Is NAC safe and beneficial for Fertility and Pregnancy?
A: Recent studies have concluded that using NAC does not pose a risk to maternal or foetal health. Additionally, 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. This is due to the antioxidant glutathione, which NAC boosts, and its positive effects on insulin secretion and resistance, often associated with PCOS. NAC has been identified as a promising treatment for increasing insulin sensitivity in PCOS patients with hyperinsulinemia, as suggested by an article in Women's Health Reviews.

Additionally the anti-inflammatory properties of NAC can enhance pregnancy and delivery outcomes for infected women predisposed to premature labour. A daily oral intake of 0.6 grams of NAC alongside progesterone from the sixteenth week of pregnancy can mitigate the risk of preterm birth recurrence. Furthermore, NAC can address acetaminophen overdose complications, which are the most prevalent drug-related incidents affecting pregnant women.
