Nervous System Support
Benefits and Features
Alpha-ketoglutarate is a nitrogen scavenger and a source of glutamate and glutamine that stimulates protein synthesis and slows the loss of muscle protein.
Detail Overview
Alpha-ketoglutaric acid (AKG) is a ketone derivative of the organic compound glutaric acid. It is important for the proper metabolism of all essential amino acids and the transfer of cellular energy in the citric acid, or Krebs cycle. Individuals with high protein intake or gastrointestinal microbiota imbalance may benefit from supplemental AKG to help balance ammonia levels and support tissue health.

Detoxification support
Glutathione is a powerful antioxidant and detoxifying compound consisting of three amino acids: cysteine, glutamic acid, and glycine.† Produced in the liver, glutathione assists with detoxifying xenobiotics and heavy metals, neutralizes hydrogen peroxide, maintains the integrity of blood cells, and helps transport amino acids across cell membranes.† It aids in the breakdown of oxidized fats and is necessary for carbohydrate metabolism.† Glutathione is also involved in metabolizing insulin and regulating blood glucose levels.† These hypoallergenic formulations have been specifically designed using the active, reduced form of glutathione for maximum benefit.
