Vitamin E protects against oxidative stress in OA

Doctors said vitamin E may help the body regulate oxidative free radicals and maintain antioxidant reserves.

In the study, 40 people with OA of the knee, aged 50 to 70, took 200 IU of vitamin E per day. Compared to 40 similar healthy adults before the start of the study, those with OA had lower levels of several antioxidant enzymes and greater signs of inflammation than the healthy participants.

After three months of taking vitamin E, while signs of inflammation had not changed, the OA group had significantly higher levels of antioxidant enzymes.

Discussing their findings, doctors said these results confirm that vitamin E protects against the deteriorating effects of knee OA due to oxidative stress. Due to its potential role in reducing the inflammation that occurs in OA, the doctors called for further study of vitamin E.
