Turmeric offers benefits as a powerful anti-inflammatory and antioxidant due to its active compound, curcumin. Whole turmeric may help with conditions like arthritis and depression, protect heart health by lowering cholesterol and blood pressure, and potentially support brain health by boosting brain-derived neurotrophic factor (BDNF). It also provides vitamins, minerals, and fiber, though its absorption is lower than curcumin supplements.
