Curcumin has well established anti-inflammatory and antioxidant properties. This study examined if a bioavailable form of curcumin could reduce the damage from oxidative stress and inflammation caused by exercise. It was a randomized, placebo controlled double blind study with 30 participants split into a treatment group, which received 500 mg of bioavailable curcumin per day, or the control group, which received placebo. Muscle damage from exercise was induced by 45 minutes of treadmill running with suitable modifications to ensure eccentric muscle injury. All subjects received a nutritional supplement containing 2-4 g of protein and 25-30 g of carbohydrate 1 hour before the exercise and 500 mL of water. They found that those in the bioavailable curcumin group had significantly reduced pain (p<0.0001), slightly reduced creatine kinase concentrations (p=0.1873) and increased VO2 max values (p=0.0009) compared to placebo. No serious adverse events were reported. The authors concluded that the bioavailable curcumin used was a safe and effective supplement to improve post workout muscle recovery.
