Beta-alanine is a popular ingredient in many pre-workout and other supplements due to its ability to improve endurance and reduce fatigue during high-intensity exercise.
However, one common side effect of beta-alanine supplementation is that it causes a tingling or itching sensation, often referred to as "paresthesia."
This sensation is harmless and temporary; some people enjoy it, while others don't.
In this article, we will explore the science behind the beta-alanine tingling sensation, including how it is caused, why it varies in intensity, and whether it impacts the supplement's effectiveness.
