Creatine and Numb Legs When You Run

Why It Matters

The discussion matters for recreational athletes and clinicians weighing the trade-offs of a common supplement: if creatine appears to cause exercise-limiting symptoms, discontinuation may be warranted because its marginal gains rarely outweigh lost training capacity.

Summary

Two experts discuss anecdotal reports linking creatine supplementation to numbness in the legs during running, noting initial skepticism but acknowledging stronger causality when symptoms resolve on discontinuation and recur on rechallenge. They concede there isn’t a clear physiological mechanism tying creatine to localized numbness, but accept patient-reported patterns as persuasive. Given creatine’s generally modest performance benefits for most users, the speakers recommend prioritizing the ability to run and perform conditioning over continued supplementation. The practical takeaway is to stop creatine if it impairs exercise tolerance and reassess benefits versus harms.

She started creatine and her legs go numb about 10 minutes into every run. Should she quit?
