Additional Information

Money-back guarantee

It's standardized for only small sized OPCs to better ensure absorption. Large OPCs (tannins) in grape seed extract cannot be absorbed. VX1 offers the clinically recognized level of OPCs for consistent, life-enhancing benefits.

Many other grape seed extracts include high levels of tannins - OPCs with a high molecular weight - providing zero absorption with few health benefits.
