About
Taurine is a naturally occurring amino sulfonic acid synthesised endogenously from methionine and cysteine, and obtained through dietary consumption of meat and dairy products. It is added to energy drinks and dietary supplements for its roles in cellular hydration, osmoregulation, cardiovascular function, and neurological support.
Safety summary
Both FDA and EFSA have concluded that taurine has no potential for carcinogenicity, mutagenicity, genotoxicity, or reproductive toxicity. An observed safe level of 3,000 mg/day for adults has been established from published human studies. Caution is warranted for children, pregnant and lactating women, and individuals with impaired renal function, as excess taurine is primarily eliminated via renal excretion.
Regulatory landscape
| Jurisdiction | Status | Note |
|---|---|---|
| EFSA (European Food Safety Authority) (European Union) | Approved | EFSA ANS Panel (2009 scientific opinion) concluded that taurine exposure from regular energy drink consumption is not a safety concern and resolved prior SCF concerns regarding possible neurological effects. Taurine is also included in the positive list of additional substances (amino acids and related compounds) under EU Regulation No. 609/2013 for foods for specific nutritional groups. The 1,400 mg/day figure is the EFSA reference intake used in energy-drink risk characterisation, not a formal ADI.source |
| FSSAI (Food Safety and Standards Authority of India) (India) | Approved | Permitted in carbonated caffeinated energy drinks at a maximum of 2,000 mg per serving. Mandatory label warning: 'Not recommended for children, pregnant or lactating women, persons sensitive to caffeine.' Taurine is also under review as part of FSSAI's broader energy-drink standards risk-assessment process.source |
| FDA (Food and Drug Administration) (United States) | Approved | GRAS determination (GRN 000586) for use as an ingredient in noncarbonated, flavored, water-based beverages at 0.0045%; 3,000 mg/day recognised as the observed safe level for adults based on published human safety reviews.source |
