Overview
Taurine (2-aminoethanesulfonic acid) is a naturally occurring sulfonic acid and conditionally essential nutrient found abundantly in mammalian tissues. Unlike most amino acids, taurine is not incorporated into proteins but exists as a free amino acid, playing critical roles in bile acid conjugation, osmoregulation, membrane stabilisation, antioxidant defence, and modulation of calcium signalling. It is essential for cardiovascular function and development of skeletal muscle, retina, and the central nervous system.
Taurine is found naturally in meat, fish, and dairy products and is biosynthesised in mammals from cysteine and methionine. AuSaMicS supplies Taurine at biochemical grade (>98% purity) with full batch traceability and Certificate of Analysis included with every order.

Biological Roles & Functions
Bile Acid Conjugation
Conjugates bile acids in the liver (taurocholic acid) — essential for fat digestion and absorption.
Osmoregulation
Major intracellular osmolyte — regulates cell volume in response to osmotic stress.
Antioxidant Defence
Reacts with HOCl to form taurine chloramine — modulates oxidative stress and inflammation.
Cardiovascular Function
Essential for cardiac muscle contractility, rhythm regulation, and cardioprotection.
Neurotransmission
Inhibitory neurotransmitter-like activity; long-term potentiation in hippocampus and striatum.
Retinal Development
Essential for photoreceptor function and normal retinal development in neonates.
