Grape seeds are rich in antioxidants, particularly proanthocyanidins. This active compound helps reduce inflammation, improve blood circulation, support recovery, and reduce pain and discomfort in the legs. It can also help reduce the risk of heart disease by inhibiting the oxidation of harmful cholesterol and protecting cardiovascular health. Grape seeds can also support the synthesis and maintenance of collagen, a protein essential for the health of connective tissues, helping reduce muscle and joint pain.
