Buying Guide
Primary Benefits: Sleep vs Heart and Recovery
Glycine is well known for its calming effect on the brain, making it an excellent choice for promoting relaxation and healthy sleep. It helps you fall asleep without leaving you groggy the next day. Taurine, on the other hand, is best recognized for supporting heart health, nervous system function, and muscle recovery after exercise. If your main goal is better sleep, glycine likely wins. If you focus on cardiovascular or athletic recovery, taurine stands out. For a broader look at amino acids for performance, see our best all-in-one amino acid supplements list.
