Pure Encapsulations HM Complex - Designed to support antioxidant defense, while promoting healthy liver and immune function. This formula including chlorella, lipoic acid, N-Acetyl-L-Cysteine (NAC), selenium and vitamin C, scavenges free radicals. These antioxidants may also help regulate oxidative stress induced by heavy metals – such as mercury, arsenic, cadmium, lead and tin – that results from common, mild environmental exposure. In addition, NAC provides important support for the liver by enhancing glutathione concentration. Similarly, l-methionine, an essential amino acid, supports glutathione production and encourages healthy liver function, including phase II detoxification pathways. HM Complex also contains modified citrus pectin and zinc. The unique characteristic of modified citrus pectin is that it has a low molecular weight, which allows it to easily pass through the intestinal barrier. Zinc is essential for a wide range of physiological functions and is part of a cysteine-rich metal-binding protein. By promoting healthy neutrophil, natural killer cell, and T-lymphocyte function, zinc plays an important role in supporting the body’s defense system.
