Which supplement is associated with antioxidants and may support heart health?

Grape seed extract is known for its high antioxidant content, particularly oligomeric proanthocyanidin complexes (OPCs), which are compounds that help neutralize free radicals in the body. These antioxidants play a crucial role in reducing oxidative stress, which is linked to various chronic diseases, including heart disease. The supportive role of grape seed extract on heart health comes from its potential to improve blood circulation, lower blood pressure, and maintain healthy cholesterol levels, all of which are essential for cardiovascular wellbeing.

The other options, while they each have their own respective benefits, do not primarily focus on antioxidant properties or direct support to heart health like grape seed does. Kava Kava is often used for its calming effects and not specifically linked to cardiovascular health. Melatonin is primarily known for regulating sleep cycles rather than its heart health benefits. Ginger, while beneficial for digestion and possessing some antioxidant properties, does not primarily align with the heart health benefits associated with grape seed extract.
