NOW Taurine 1000 mg – Double Strength, Nervous System Health, Healthy Visual Function, 100 Veg Capsules

What Is NOW Taurine 1000 mg Double Strength?

NOW Taurine 1000 mg Double Strength delivers a therapeutic dose of free-form Taurine — one of the most abundant amino acids in the human body and a conditionally essential nutrient found in the highest concentrations in the brain, retina, heart, and skeletal muscle. Despite being classified as a non-essential amino acid because the body can synthesize it from cysteine and methionine, taurine’s endogenous production is often insufficient under conditions of stress, illness, aging, or vigorous exercise — making dietary or supplemental intake critically important for maintaining optimal physiological function. Unlike most amino acids, taurine is not incorporated into proteins; instead, it functions as a free intracellular osmolyte, neuromodulator, antioxidant, and cytoprotective agent — making it one of the most functionally unique molecules in human biology.

What Does Taurine Do?

• Nervous system health — Acts as an inhibitory neuromodulator, modulating GABA and glycine receptors to support neurological calm, reduce excitotoxicity, and protect neurons from oxidative damage
• Healthy visual function — The retina has one of the highest concentrations of taurine in the body; taurine is essential for photoreceptor development, maintenance, and protection from light-induced oxidative damage
• Cardiovascular health — Supports healthy heart rhythm (antiarrhythmic), blood pressure regulation, and cardiac contractility; populations with high taurine intake show significantly lower cardiovascular mortality
• Cellular hydration & osmolyte function — Regulates intracellular water balance and cell volume, protecting cells from osmotic stress
• Antioxidant defense — Reacts with hypochlorous acid (HOCl) produced by neutrophils to form taurine chloramine, a less reactive, safer oxidant that protects surrounding tissue
• Mitochondrial support — Taurine is required for the post-translational modification of mitochondrial tRNA, essential for efficient mitochondrial protein synthesis and energy production
• Muscle function & recovery — Supports calcium handling in muscle cells, reduces exercise-induced oxidative stress, and may decrease delayed onset muscle soreness (DOMS)
• Longevity — Emerging research (2023 Science publication) identifies taurine decline as a driver of aging; taurine supplementation extended lifespan and healthspan in animal models

Who Should Take This?

• Individuals supporting nervous system health and neurological calm
• Those concerned about eye health and retinal protection
• People supporting cardiovascular function and healthy heart rhythm
• Athletes and active individuals seeking muscle performance and recovery support
• Older adults interested in longevity and healthy aging supplementation
• Vegans and vegetarians (taurine is absent from plant foods)

How to Use

Take 1 to 2 capsules 1 to 2 times daily with food, or as directed by your healthcare practitioner. Taurine is well tolerated across a wide dose range and is non-stimulating despite its inclusion in many energy drinks.
