Dietary Supplement Calming Neurotransmitter Best Before 04/2025 Taurine is a crystalline, free-form amino acid.

This critically important "pump" actually uses 7% to 40% of the ATP energy our bodies produce. Suggested use 1 tablet daily. Other ingredients Sorbitol, stearic acid, silica, modified cellulose gum, and magnesium stearate. Contains no yeast, dairy, egg, gluten, soy or wheat.
