The sensation commonly experienced after consuming pre-workout supplements, characterized by a prickly or itchy feeling, is a physiological response primarily attributed to the presence of beta-alanine. Beta-alanine is a non-essential amino acid that increases carnosine levels in muscles. Carnosine acts as a buffer, reducing the accumulation of lactic acid during high-intensity exercise. This buffering effect can delay muscle fatigue.
This tingling sensation, scientifically termed paresthesia, is not inherently dangerous for most individuals. However, the intensity of the sensation can vary greatly depending on the dosage of beta-alanine ingested and individual sensitivity. Some individuals may find the sensation mildly annoying, while others may experience more pronounced discomfort. Historically, beta-alanine has gained popularity in pre-workout formulations due to its perceived performance-enhancing benefits, with the paresthesia often considered an acceptable side effect.
