Taurine
Also known as L-Taurine, 2-aminoethanesulfonic acid
Taurine is one of the most abundant amino acids in the body, concentrated in the heart, brain, muscles, and eyes. It supports cardiovascular function, calcium handling, antioxidant defense, and a calm nervous system through its action on GABA and glycine receptors. It is the most-studied ingredient in energy drinks and is also used to support exercise performance and recovery, though those effects are more modest.
Benefits
Supports cardiovascular health
ModerateTaurine helps regulate blood pressure, calcium handling in heart muscle, and endothelial function.
May aid exercise performance and recovery
PreliminaryUsed to support endurance and reduce exercise-induced muscle damage, with mixed but promising results.
Promotes calm and supports the nervous system
PreliminaryActs on GABA and glycine receptors, which may contribute to a calming, focusing effect.
Pros & cons
Pros
- Excellent safety profile
- Inexpensive and widely available
- Supports heart and exercise
- Calming without sedation
Cons
- Performance effects are modest and mixed
- Benefits are clearest in deficiency or specific conditions
Side effects
Generally very well tolerated
Side effects are rare; taurine is one of the most abundant amino acids in the body and is cleared readily.
How to take it
Typical dose
1–3 g per day
Timing
Any time, with or without food; some take it pre-workout or in the evening for calm
Common forms
Tip: Well tolerated; doses up to about 3 g per day are considered safe for long-term use.
