L-Taurine

Appearance: White crystalline powder or colorless white crystals

Solubility: Soluble in water (~5-10 g per 100 mL at room temperature), clear and colorless solution benzene

Melting Point: 300 °C 

L-Taurine nutritional information includes the following key points:

• Taurine is a sulfur-containing amino acid but is not a protein-building amino acid, so it is not counted as dietary protein.

• Typical taurine supplements provide between 500 mg and 2000 mg per serving, though doses up to 3 grams per day are generally regarded as safe.

• Taurine contains no carbohydrates, fats, or protein in typical supplement form and thus contributes negligible calories—about 6 kcal per 2 g serving reported in some sources (mostly from amino acid content).

• Natural dietary intake of taurine from animal-based foods averages roughly 40 to 180 mg per day in typical Western diets; much lower (~17 mg) in lacto-ovo vegetarians.

• Taurine is abundant in high-protein animal foods such as shellfish, fish, meat, dairy, and certain seaweeds.

• Taurine supplements are often used to support various physiological functions but do not provide macronutrients or significant energy.

• Energy drinks and some supplements commonly include taurine in the range of 750 mg to 3 g per serving.

L-Taurine benefits are wide-ranging and largely relate to its roles in cellular health, aging, metabolism, and cardiovascular function. Key benefits supported by recent scientific findings include:

• Anti-Aging Effects: Taurine supplementation has been shown to slow aging-related decline in animal studies by reducing cellular senescence, DNA damage, and mitochondrial dysfunction. It can improve the function of various tissues including bone, muscle, brain, and the immune system, thereby enhancing both lifespan and healthspan.

• Metabolic Health: Taurine may help suppress age-associated weight gain, reduce insulin resistance, and improve blood sugar management, which can be protective against type 2 diabetes.

• Cardiovascular Support: It helps regulate blood pressure, improves heart function, and reduces cholesterol and inflammatory markers, which may reduce the risk of heart disease. Human studies indicate taurine supplementation lowers blood pressure and lipid levels in people with cardiovascular conditions.

• Exercise and Energy: Taurine levels increase after exercise, suggesting it supports energy metabolism, muscle endurance, and recovery.

• Neurological Health: Taurine protects neurons from stress-related damage, supporting neurological development and function.
