Vitamin B-6 (pyridoxine) acts primarily as an enzyme catalyst in many body processes including energy metabolism and neurotransmitter function.* Before it can be used for this purpose it must be converted into its coenzyme form (P-5-P) by the liver. P-5-P eliminates this step by providing B-6 in its converted form, allowing for greater bioavailability.Ingredients:Supplement FactsServing Size: 1 TabletAmount Per Serving% Daily ValueRiboflavin (Vitamin B-2)17 mg1000%Vitamin B-6 (from 50 mg Coenzyme Pyridoxal-5-Phosphate)33 mg1650%Calcium (from Dicalcium Phosphate)30 mg3%Magnesium (from 75% Magnesium Oxide and 25% Magnesium Taurinate)100 mg25%Other IngredientsCroscarmellose sodium, cellulose, stearic acid (vegetable source), magnesium stearate (vegetable source) and enteric coating.Not manufactured with wheat, gluten, soy, milk, egg, fish, shellfish or tree nut ingredients.
