PWS
STILL, SIDE EFFECT
No significant side effects (e.g., gastrointestinal issues) were observed or reported from the athletes during the study. The only side effect that it has been reported in few athletes of PWS group (2 participants) was a tingling sensation in the neck and the backside of the hands. The tingling sensation is a common side effect of β-alanine consumption in high doses, lasting approximately 60 min. Still, to date, no scientific evidence supports that this tingling sensation is dangerous in any way [
