Now Double Strength Taurine 1000mg Capsules are a high-potency amino acid supplement formulated to support nervous system health, healthy visual function, and normal cellular activity. Each vegetarian capsule delivers 1000mg of free-form taurine, a conditionally essential amino acid naturally found in the brain, heart, eyes, and nervous system. Taurine plays an important role in maintaining cell membrane stability, regulating nerve impulses, and supporting the movement of essential electrolytes such as potassium, sodium, calcium, and magnesium across cell membranes. It also contributes to normal fluid balance and supports neurotransmitter activity alongside glycine and GABA. The formula contains hypromellose for the vegetarian capsule shell, vegetable-derived stearic acid for manufacturing consistency, and silicon dioxide to prevent clumping. With double the taurine content of the regular 500mg formula, this vegan-friendly, non-GMO supplement provides convenient nutritional support for nervous system function and overall cellular health.
