Main highlights
- QUALITY ASSURANCE: 3rd party Lab Tested in the USA. We have our own FDA registered Food-Grade facility in the USA. All our products are 3rd-Party tested to guarantee purity
- MAINTAINS CELLULAR HEALTH: GlyNAC-ET - NAC N-Acetyl-Cysteine Ethyl Ester and Glycine can help to support cells all throughout the body and in many tissues. Studies have shown that oxidative stress caused by free radicals may contribute to premature aging of cells
- GLYNAC-ET FORMULA: A powerful precursor to Glutathione that consists of two of the three needed amino acids to make Glutathione, NACET (N-acetylcysteine ethyl ester) and Glycine. NAC Ethyl Ester has been shown to be 20x more bioavailable than NAC
- GLUTATHIONE SUPPORT: The Mother of ALL Antioxidants. NACET supplies L-cysteine 20x times more efficiently than traditional NAC, which then acts as an antioxidant itself as well as a precursor to glutathione. Glutathione is the most important and most abundant antioxidant inside of cells. The primary antioxidant mechanism involves donating an electron from the sulfhydryl (-SH) group of the cysteine molecule
- ENHANCED BIOAVAILABILITY: NACET is lipophilic (fat and water soluble) allowing it to be absorbed by red blood cells and cross the blood-brain barrier, making it significantly more effective than standard NAC supplements
- DOSAGE INFORMATION: 2 Capsules 1-2 times per day. Each capsule contains 50mg NACET and 525mg Glycine. More powerful than liposomal glutathione or regular NAC 600 mg
