"A practical supplier guide to Taurine powder (CAS 107-35-7, 2-aminoethanesulfonic acid): what it is, its chemistry and solubility, uses in energy drinks, dietary supplements, infant formula, pet feed and cosmetics, and how it pairs with creatine, L-arginine, Alpha-GPC, and vitamin C."

Taurine, chemically known as 2-aminoethanesulfonic acid, is one of those raw materials that quietly sits inside a surprising number of finished products. With the CAS number 107-35-7, it is a white crystalline powder with high purity (typically ≥99%), strong water solubility, and good thermal stability. Buyers meet it in energy and sports drinks, dietary supplements, infant nutrition, animal feed, and increasingly in personal-care formulations. This article walks through what the material is, where it is used, and how it pairs with other ingredients we supply.
What taurine actually is
Structurally, taurine is a sulfur-containing amino sulfonic acid rather than a standard amino acid — it carries the molecular formula C₂H₇NO₃S and a molecular weight of about 125.15. It occurs naturally in the body, where it concentrates in tissues with high metabolic demand such as the heart, brain, retina, and skeletal muscle. Unlike protein-building amino acids, it is not incorporated into peptides; instead it stays free in cells, where it helps balance fluids, stabilize cell membranes, and support normal neuromuscular function.
That profile is exactly why formulators like it. It is a fine, white crystalline powder that dissolves cleanly in water and holds up well under typical processing temperatures, so it fits both dry blends and liquid concentrates. From a sourcing standpoint, what matters most is consistent assay, low heavy metals, and a clean sensory profile — all of which we verify per batch before shipment.
Where the demand comes from
The largest single use is still functional beverages. Taurine is a fixture in energy drinks and many sports-hydration formulas because consumers associate it with alertness and exercise support. In dietary supplements it is sold on its own in capsules and tablets, and is frequently built into cardio and endurance stacks where it is valued for its role in normal cardiovascular and muscle function.
Two other categories are easy to overlook but very steady. Infant nutrition relies on taurine because newborns have limited ability to synthesize enough of it; most standard formulas include a defined level. And in pet and aquafeed, it is effectively non-negotiable — cats cannot make it at all, so taurine deficiency in feline diets is a well-documented health risk. Aquaculture feeds use it for the same reason: the animals need a dietary source.
In pharma, taurine appears as an intermediate and as a component in certain registered products, which keeps a consistent technical-grade demand alongside the food and supplement volumes.
Building taurine-based formulas with related actives
Taurine is rarely the only active in a product, and the combinations tend to follow clear logic. In sports and pre-workout formats it is commonly stacked with creatine monohydrate (CAS 6020-87-7), which targets power and training output through a different pathway, and with L-Arginine (CAS 74-79-3), an amino acid widely used to support healthy blood flow. For products that also aim at focus and reaction time, Alpha-GPC (CAS 28319-77-9) is a natural companion choline source in the same formulation family.
In antioxidant and wellness blends, taurine pairs well with L-Ascorbic Acid (CAS 50-81-7), a classic vitamin C raw material used for its antioxidant and nutrient role across food, supplement, and cosmetic applications. Keeping the active set inside one trusted supply chain simplifies documentation and batch traceability for the brand.
The personal-care angle
Beyond ingestible products, taurine has a real place in cosmetics. Formulators use it for its moisturizing and free-radical-scavenging properties, and it fits comfortably into serums, masks, and daily skincare aimed at maintaining skin hydration and resilience. When a taurine-based skincare line needs supporting actives, we often see it combined with ethylhexylglycerin (CAS 70445-33-9), a multifunctional preservative booster and skin-conditioning agent, and with Alpha-Arbutin (CAS 84380-01-8), a brightening ingredient used in tone-evening formulas. The combination gives brand owners a coherent "hydration plus protection" story.
Handling, packaging, and quality
Taurine is straightforward to handle compared with many heat- or moisture-sensitive actives. We still recommend sealed packaging kept in a cool, dry, well-ventilated area, away from strong acids and oxidizing agents. Standard packing is 25 kg per drum or per bag depending on the order, and palletized shipments are available for full containers.
Every lot is sampled and tested before it leaves the warehouse. Typical specifications buyers request include assay (≥99%), loss on drying, residue on ignition, heavy metals, and microbial limits. We ship with commercial invoice, packing list, bill of lading, COA, and certificate of origin, and we can provide a sample for in-house verification before any volume commitment. For regulated food and infant-nutrition use, confirming the exact grade and local compliance limits with your quality team is always the right first step.
Ordering and support
Whether you are scaling an energy-drink line, a sports-supplement SKU, an infant-formula blend, or a taurine-forward skincare product, a reliable taurine (CAS 107-35-7) supply is the foundation. We focus on consistent specification, full documentation, and responsive lead times rather than generic promises. If you need pricing, a current COA, or a sample of taurine powder, reach out to our sales team — we can usually quote the same business day and arrange testing support for your formulation work.
