A common sensation experienced by individuals who consume pre-workout supplements is a tingling or prickling feeling, often described as paresthesia. This effect is primarily attributed to the presence of beta-alanine, an amino acid frequently included in pre-workout formulations. For example, an individual might notice this sensation most prominently in the face, neck, and hands after ingesting a pre-workout supplement containing a significant dose of beta-alanine.
The inclusion of beta-alanine in pre-workout supplements stems from its ability to enhance muscular endurance. Beta-alanine increases the concentration of carnosine in muscles, which acts as a buffer against the buildup of lactic acid during high-intensity exercise. While the paresthesia is generally harmless, it is a noticeable physiological response that can be perceived differently by various individuals. Understanding the cause of this sensation allows for a more informed approach to supplement usage and management of expectations related to its effects.
