What is taurine
Taurine is a non-protein amino acid, naturally occurring in the human body, which has many key functions. Unlike other amino acids, taurine is not directly used for protein synthesis, but plays an important role in osmoregulation, neuroprotection and fat metabolism. Taurine is particularly concentrated in tissues with high energy requirements, such as the heart, brain, muscles and retina.
Sources of taurine
Natural sources of taurine are mainly animal products such as meat, fish and seafood. Vegetarian and vegan diets can lead to reduced taurine levels, so people who avoid animal products may want to consider supplementation. Taurine is also available in supplement form, which is widely used in sports medicine and in the treatment of certain medical conditions.
The role of taurine in the cardiovascular system
Taurine and heart health
Taurine plays a key role in regulating blood pressure and heart rhythm. Research shows that taurine supports heart health by modulating calcium levels in heart muscle cells, which stabilises heart muscle function. Taurine also lowers blood pressure, which reduces the burden on the heart and the risk of cardiovascular disease.
Anti-oxidative stress
As a powerful antioxidant, taurine protects heart cells from oxidative stress-induced damage. Oxidative stress contributes to the development of atherosclerosis, and taurine counteracts the formation of free radicals, reducing the risk of cardiovascular disease.
Cholesterol regulation
Taurine influences lipid metabolism, helping to regulate blood cholesterol levels. Studies indicate that taurine supplementation can lower LDL cholesterol, a key risk factor for atherosclerosis.

Taurine and neural function and brain health
Neuroprotective effects of taurine
Taurine is a neuroprotector, meaning that it protects nerve cells from damage and oxidative stress. In the brain, taurine supports the function of neurons and protects them from toxic substances that can lead to neurodegeneration.
Effects on neurotransmission
Taurine acts as a modulator of neurotransmitters, particularly GABA (gamma-aminobutyric acid), which is the main neurotransmitter with calming effects. Thus, taurine may reduce anxiety, stress and promote better sleep.
Taurine and neuroplasticity
Taurine has the ability to support neuroplasticity - the ability of neurons to adapt and regenerate. This property may have potential applications in the treatment of neurodegenerative diseases such as Alzheimer's or Parkinson's disease.
Effects of taurine on the muscular system
Taurine in skeletal muscle
Taurine is crucial for the proper functioning of skeletal muscles, supporting their performance and strength. It maintains electrolyte balance in muscles, which is essential for proper contractility and recovery.
Supporting recovery after exercise
Research indicates that taurine can accelerate muscle recovery after intense exercise, thanks to its antioxidant and anti-inflammatory properties. Taurine helps to scavenge free radicals and reduces the risk of muscle cramps.
Taurine and endurance
Taurine improves muscular endurance by optimising cellular metabolism and supporting regeneration. It can increase the ability of muscles to sustain exercise for longer, which is particularly important for athletes.
Taurine and liver detoxification and protection
Effects of taurine on liver health
Taurine has a protective function in the liver, preventing cell damage caused by toxins, alcohol and abnormal lipid metabolism. Taurine helps stabilise hepatocyte cell membranes and reduces inflammation in the liver.
Taurine and detoxification
Taurine supports liver detoxification by supporting the secretion of bile acids, which are key in eliminating toxins and excess fats from the body. Research indicates that taurine may also reduce fatty liver, particularly in cases of non-alcoholic fatty liver disease (NAFLD).
Research into the effects of taurine on liver disease
The results of clinical trials suggest that taurine supplementation may be effective in the treatment of non-alcoholic fatty liver disease (NAFLD), thanks to its anti-inflammatory and detoxifying properties.

Taurine and eye health
The role of taurine in the retina
Taurine plays a key role in the normal function of the retina, being one of the most important amino acids present in this tissue. Taurine supports the structure and function of the retina, protecting photoreceptor cells from oxidative damage that can lead to vision degradation. Taurine deficiency in the retina can lead to severe visual impairment and even retinal degeneration.
Effects of taurine on macular degeneration
Research suggests that taurine may protect against degenerative diseases of the eye, such as macular degeneration (AMD). AMD is one of the leading causes of vision loss in older people. Acting as a powerful antioxidant, taurine neutralises free radicals in the tissues of the eye, helping to reduce the risk of developing this disease.
Protection against oxidative stress in the eyes
Oxidative stress is one of the main causes of damage to retinal cells. Acting as an antioxidant, taurine neutralises free radicals that can lead to damage to eye tissues, thereby promoting eye health and the prevention of degenerative diseases.
Taurine and regulation of sugar metabolism
Effect of taurine on blood glucose levels
Taurine plays an important role in the regulation of blood glucose levels. Research suggests that taurine may improve insulin sensitivity, which helps to maintain normal blood sugar levels. Taurine supplementation shows potential in the prevention and treatment of insulin resistance, which is important for the management of type 2 diabetes.
Research on taurine in diabetes therapy
Clinical studies indicate that taurine supplementation can help lower blood glucose levels and improve insulin sensitivity. Long-term taurine supplementation may help control sugar levels, making it a potential supportive agent in diabetes therapy.
Taurine and pancreatic health
Taurine supports pancreatic function by improving insulin secretion and protecting pancreatic beta cells, which are responsible for insulin production. The protective effect of taurine on the pancreas may help in the prevention of diabetes complications.
Taurine and immune function
Effects of taurine on the immune system
Taurine acts as a regulator of the immune system, supporting the body's normal immune response. Its effects include influencing the activity of lymphocytes and macrophages, which play a key role in fighting infection and inflammatory reactions.
Anti-inflammatory effects
Taurine has anti-inflammatory properties, which is particularly important for the prevention of chronic diseases such as cardiovascular disease and diabetes. It works by inhibiting the production of pro-inflammatory cytokines, which helps to reduce inflammation in the body.

Taurine and autoimmunity
Research suggests that taurine may support the treatment of autoimmune diseases by alleviating symptoms and reducing the severity of autoimmune reactions. Due to its immunomodulatory properties, taurine may reduce excessive immune system responses, which is important in diseases such as rheumatoid arthritis and multiple sclerosis.
Therapeutic applications and taurine supplementation
Benefits of taurine supplementation
Taurine is widely used in supplementation, particularly in the context of supporting heart, liver, muscle and nervous system health. Regular supplementation can be beneficial in reducing the risk of cardiovascular disease, improving muscle performance, and protecting nerve cells from damage.
Recommended dosage and safety
The recommended dose of taurine supplementation is usually between 500 mg and 2,000 mg per day, depending on individual needs and health status. Taurine supplementation is considered safe; however, caution should be exercised in the case of certain medical conditions, such as renal failure.
Potential side effects and contraindications
Although taurine is generally considered safe, excessive supplementation may lead to gastrointestinal complaints such as diarrhoea and nausea. People with chronic kidney disease should consult their doctor for supplementation.
Potential future directions for taurine research
New areas of research
Scientists are becoming increasingly interested in the potential applications of taurine in the treatment of neurodegenerative diseases such as Alzheimer's and Parkinson's disease. Research into its effects on neuroplasticity and nerve cell protection may provide new insights into taurine's therapeutic potential.
