Interesting Fact
Grape Seeds Are Packed With Natural Polyphenols
Grape seed extract is rich in polyphenols, especially proanthocyanidins, which are naturally occurring compounds also found in dark chocolate and certain berries. These polyphenols contribute to the characteristic deep color of grape seeds and are a major reason this ingredient is included in many supplement blends focused on overall wellness and plant-based support.
