P5P is required for proper absorption of B12 and magnesium, and for the production of gastric HCl.* Metabolic Support: P5P is an important coenzyme in the metabolism of carbohydrates, fats and proteins, and helps release glycogen from the liver and muscles.* Central Nervous System Support: In addition, P5P helps maintain the balance of sodium and potassium, which regulates body fluids and promotes the healthy functioning of the nervous and musculoskeletal systems.* Pure Quality: Our supplements are made with only premium ingredients sourced from trusted suppliers and guided by our nutritional experts, then carefully manufactured and tested to verify their potency and purity.
