Turmeric may be the most effective nutritional supplement in existence. Studies show that turmeric has major benefits on the body and brain. Many of these benefits come from its main active ingredient, curcumin. Curcumin supresses many molecules that are known to play a major role in inflammation. Chronic inflammation contributes to some common health conditions. Turmeric is used widely in natural skincare products for its anti-aging and restorative qualities.
