The sensation of itchiness experienced by some individuals after consuming pre-workout supplements is often attributed to a specific amino acid included in the formulation. This amino acid, commonly used to enhance athletic performance, stimulates nerve endings near the skin’s surface, triggering a tingling or itching sensation.
Understanding the cause of this paresthesia is important for both consumers and manufacturers. While generally harmless, the sensation can be distracting or uncomfortable for some, impacting their workout experience. Historically, the presence of this amino acid in pre-workout formulations has been linked to its perceived ergogenic benefits, outweighing the discomfort for many users.
