Taurine is a naturally occurring sulfur-containing amino acid found in various tissues of the human body, especially in the brain, heart, retina, and muscles. While not used to build proteins like other amino acids, taurine plays several essential roles in maintaining health.
🧬 What is Taurine?
- Chemical Name: 2-aminoethanesulfonic acid
- Type: Conditional amino acid (can be synthesized by the body, but often supplemented)
- Found In: Meat, fish, dairy, and energy drinks like Lipovitan D, Red Bull, and Monster
✅ Benefits of Taurine
1. Improves Physical Performance
- Helps reduce muscle fatigue during workouts
- Supports better endurance and energy levels
- Common in pre-workout supplements and energy drinks
2. Supports Heart Health
- Helps regulate blood pressure and cholesterol levels
- Improves vascular function and heart muscle performance
- May reduce the risk of heart failure when combined with proper medication
3. Protects Eye Health
- Concentrated in the retina — essential for maintaining clear vision
- May help protect against retinal degeneration and oxidative stress
4. Boosts Brain Function
