This form is extracted from grape (Vitis vinifera) seed and standardized to at least 90% total polyphenols measured by the UV/Folin method. Unlike the 95% OPC grade, which reports the oligomeric proanthocyanidin subset specifically, this grade declares the broader total-polyphenol pool, so its marker basis is total phenolics rather than the OPC fraction. It is a standardized whole seed extract rather than an isolated compound or a ratio-defined concentrate. Physical form is a fine brown-red powder. It is produced in capsule, tablet, and powder dosage formats.
