Beta-alanine is a non-essential amino acid that is not utilized in protein synthesis.
Instead, it combines with histidine, another amino acid, to form carnosine in muscles and brain tissues.
Carnosine acts as a buffer against acid buildup in muscles, which can lead to fatigue.
This buffering capacity has made beta-alanine a popular supplement among athletes.
However, the potential benefits of beta-alanine go beyond athletic performance.
Emerging studies suggest it might have neuroprotective effects, which could be beneficial in cases of PTSD.
