▶▶▶ N-Acetyl-L-Cysteine Ethyl Ester ：Studies have shown that NACET has much higher bioavailability (around 60%) than NAC. NACET rapidly enters the cells, then is trapped, and transforms into NAC and Cysteine. Because NACET (but not NAC) may pass the blood-brain barrier and provide a variety of beneficial antioxidant actions, NACET is present in the cells of various tissues, including the brain. NACET is known to be beneficial to the brain system.

▶▶▶ Powerful Antioxidant Effects: As a precursor to the powerful antioxidant glutathione, NACET enhances protective antioxidant activity throughout the body. Because of its ability to enter cells and create NAC and cysteine, N-Acetylcysteine bonds with glutamine and glycine to form glutathione. NACET is the number 1 way to increase cellular Glutathione content. NACET helps increase energy levels, improve the immune system.

▶▶▶ NACET Ingredients : With the addition of 600mg Glycine, 30 mcg Selenium supplement, and 50 mcg Molybdenum. Glycine is required for Glutathione, tissue maintenance, hormone creation, and enzyme synthesis. Selenium is involved in the removal of hydrogen peroxide and lipid peroxide produced during oxidative stress.Molybdenum works in the body to break down proteins that certain enzymes then use to break down toxins in the body.
