Taurine

Taurine (or L-Taurine) is the most abundant amino acid in white blood cells and plays a vital role in strengthening the immune system. Since it's a conditionally essential amino acid, a healthy individual can produce the minimal amount required for these essential daily functions. However, certain individuals may benefit from taking a supplement. 

Taurine supplements have been linked to fitness, and there are studies that support the claims that it may benefit athletic and workout performance. 

Taurine is an energy-enhancing amino acid that aids muscle hydration, making muscles feel fuller. It also helps to moderate calcium and lower cholesterol levels and is a good choice of supplement to help keep the body in overall optimal working order.  

Human studies indicate that trained athletes who supplement with taurine experience improved exercise performance. 

Taurine has also been shown to protect muscles from cell damage and oxidative stress. Through its high potassium content, Taurine is also believed to play a key role in the transportation of serotonin.
