Grape Seed Proanthocyanidin Extract

The Grape Seed Proanthocyanidin Extract offered by Hebei Tianao Technology Co., Ltd is obtained from screened grape seeds. The seeds are processed using an advanced green extraction technology that avoids organic solvents. This method yields a high‑purity anthocyanin concentrate that retains the natural antioxidant profile of the seed kernel. The supplier describes the extract as possessing antioxidant activity several times greater than that of vitamin C or vitamin E.

In the nutraceutical sector, proanthocyanidin extracts are commonly standardised to a minimum of 90 % total proanthocyanidins, a benchmark that aligns with the product’s intended potency. Typical moisture content for such plant extracts is kept below 5 % to ensure stability during storage. The extract is supplied as a fine powder, usually passing through a 100‑200 mesh screen, which facilitates easy blending into capsules or liquids. While the listing does not specify a certified grade, the described green extraction aligns with industry practices for preserving bioactivity.

This ingredient is widely used in dietary supplement formulations, anti‑age skin care products, and functional foods that target oxidative stress. Importers such as supplement manufacturers, cosmetic formulators, and health‑food processors constitute the primary buyer segment. Buyers should request a Certificate of Analysis and sample to verify purity and moisture before confirming bulk orders.
