What is Taurine?
This post was written with Consensus AI Academic Search Engine – please read our Disclaimer at the end of this article. Taurine is a sulfur-containing amino acid that plays a crucial role in various physiological processes in the body. Although it is not incorporated into proteins, taurine is abundant in many tissues and is involved in numerous biological functions. This article explores the sources, functions, and potential therapeutic applications of taurine. Other names include: 2-Aminoethanesulfonic Acid, 2-Aminoethylsulfonic Acid, 2-Aminoethane Sulfonic Acid, Acide Aminoéthylsulfonique, Acide Kétoisocaproïque de Taurine, Acid Aminoethanesulfonate, Aminoethanesulfonate, Aminoéthylsulfonique, Dibicor, Éthyl Ester de Taurine, L-Taurine, Taurina, Taurine Ethyl Ester, Taurine Ketoisocaproic Acid.
Sources of Taurine
Taurine can be obtained from both endogenous and exogenous sources. Endogenously, it is synthesized in the liver and kidneys from the amino acids methionine and cysteine. Exogenously, taurine is found in high concentrations in animal tissues, particularly in fish and seafood4 9.
Physiological Functions
Taurine is involved in a wide array of biological and physiological functions, including:
- Osmoregulation: Taurine helps maintain cell volume and fluid balance10.
- Membrane Stabilization: It stabilizes cell membranes and protects cells from damage4 7.
- Calcium Homeostasis: Taurine regulates calcium levels within cells, which is crucial for various cellular functions5.
- Antioxidation: It acts as an antioxidant, protecting cells from oxidative stress4 6.
- Neuromodulation: Taurine modulates neurotransmission and has protective effects on the nervous system5.
Therapeutic Applications of Taurine
Sports and Exercise
Taurine has gained popularity as a supplement among athletes. Studies suggest that taurine supplementation can improve aerobic and anaerobic performance, reduce muscle damage, and enhance recovery1. However, the findings are mixed, and more research is needed to draw definitive conclusions.
Cardiovascular Health
Taurine has been approved for the treatment of congestive heart failure in Japan and shows promise in treating other cardiovascular diseases. It helps regulate antioxidation, energy metabolism, and calcium homeostasis, which are crucial for heart health2.
Neurological Disorders
Taurine demonstrates potential therapeutic effects against various neurological disorders, including neurodegenerative diseases, stroke, and epilepsy. It helps attenuate inflammation and oxidative stress, modulates ER stress, and regulates neuronal activity5.
Diabetes and Metabolic Diseases
Taurine has shown beneficial effects in managing diabetes and its complications. It helps reduce oxidative stress and inflammation, which are common in diabetic conditions6 7.
Obesity
Taurine supplementation has been found to alleviate obesity and related metabolic diseases. It helps reduce oxidative stress and inflammation in adipose tissues and improves metabolic health8.
Cancer
Recent studies have shown that taurine can inhibit tumor formation and progression in certain cancer models. It induces apoptosis and increases the levels of tumor suppressor proteins3.
Visual Fatigue
Taurine supplementation may help reduce visual fatigue by protecting retinal cells and improving eye health9.

Adverse Effects of Taurine
Cardiac and Blood Pressure Effects
Taurine supplementation can ameliorate adverse cardiac effects caused by perinatal taurine depletion and high sugar intake, but it does not significantly affect body weight, heart weight, or plasma electrolytes in adult female rats1.
Taurine ingestion has been shown to reduce systolic and diastolic blood pressure in humans without reported adverse events, suggesting it is generally safe for blood pressure regulation2 5.
Neurological and Behavioral Effects
Chronic high doses of taurine may have adverse effects on motor coordination and overall movement time in mice, indicating potential negative impacts on the nervous system with prolonged exposure8.
Taurine, when combined with caffeine in energy drinks, may pose risks to the adolescent brain, potentially leading to adverse neurological effects, especially with chronic high-dose consumption10.
Retinal and Visual Effects
Taurine depletion induced by β-alanine supplementation can lead to significant reductions in retinal nerve fiber layer thickness and impair axonal transport in retinal ganglion cells, suggesting potential adverse effects on vision4.
Reproductive and Developmental Effects
Taurine supplementation in a maternal obesogenic diet model showed protective effects on offspring but increased neonatal mortality in normal pregnancy settings, indicating potential risks during pregnancy6.
Chemotherapy and Drug Interactions
Taurine has protective effects against chemotherapy-induced toxicities, including cardiotoxicity and testicular toxicity, due to its antioxidant properties. However, its interaction with the efficacy of anti-cancer drugs remains unclear3 7 9.

How has Taurine Improved Patient Outcomes?
Inflammation and Traumatic Brain Injury (TBI)
Taurine supplementation significantly reduces inflammatory markers such as IL-6 and improves clinical outcomes like the Glasgow Coma Scale in TBI patients1 3.
Psychiatric Disorders
In patients with first-episode psychosis, taurine significantly improves symptomatology, including reductions in psychotic symptoms and depression scores, although it does not enhance cognitive function2.
Cardiovascular Health
Taurine supplementation improves functional class, pulmonary symptoms, and clinical examination outcomes in patients with congestive heart failure4.
It also shows potential benefits in improving diastolic and systolic function, exercise capacity, and hemodynamic parameters in heart failure patients, although more robust clinical trials are needed5.
In prehypertensive individuals, taurine significantly lowers both systolic and diastolic blood pressure and improves vascular function7.
Taurine is associated with higher in-hospital mortality and poor neurological outcomes in patients after out-of-hospital cardiac arrest, suggesting a complex role that requires further investigation8.
Metabolic Health and Diabetes
Taurine supplementation improves oxidative stress indices and reduces inflammatory biomarkers in patients with type 2 diabetes, indicating its potential to alleviate diabetes-induced complications9.
Meta-analysis data suggest that taurine can lower blood pressure and improve lipid profiles by reducing total cholesterol and triglyceride levels, although it does not significantly affect fasting blood glucose or body weight10.
Elderly Surgical Patients
In elderly hip fracture patients, taurine supplementation reduces postoperative oxidative stress but does not significantly improve morbidity or mortality outcomes6.
