Intense exercise—especially eccentric movements like downhill running or heavy weightlifting—can cause microscopic muscle damage, inflammation, and soreness. While this process is part of adaptation, excessive damage can delay recovery and hinder performance. A recent study found that curcumin, a compound derived from turmeric, may help reduce muscle damage and soreness, potentially speeding up recovery.

Researchers analyzed the findings of 11 studies on curcumin and exercise-induced muscle damage. The various studies focused on healthy adults who exercised regularly and took curcumin before, during, or after workouts.

The analysis revealed that curcumin supplementation may ease muscle soreness, reduce inflammation, and improve recovery after strenuous exercise. However, the benefits depended on dose (which ranged from 90 milligrams to 2.5 grams), bioavailability, and timing, with post-exercise supplementation appearing most effective.

These findings suggest that curcumin could be a useful supplement for athletes looking to minimize muscle soreness and recover faster. However, its low bioavailability may limit its effectiveness. In addition, the investigators noted that many of the studies were small, limiting their findings' applicability. Curcumin is a polyphenolic compound.
