Taurine facilitates the passage of sodium, potassium and possibly calcium and magnesium ions into and out of cells and to electrically stabilize the cell membranes. Additionally, taurine is a sulfur-containing compound and is therefore important for phase II detoxification pathways as well as being a key ingredient in the formation of bile acids. The sulfation pathway is responsible for the metabolism of steroidal hormones, alcohol, a variety of prescription medications and phenolic compounds. It is apparent, therefore, that increased detoxification demands, i.e., high alcohol or medication ingestion, can lead to higher taurine needs and possible relative deficiency. Directions: Use 1 capsule twice daily or as directed by your healthcare practitioner. Ingredients: Taurine, Microcrystalline cellulose, vegetable stearate.
