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.

Heart and arteries Healthy blood sugar Immune system High absorption OPCs - Tannin free! For your good health Terry

Supports healthy levels already within normal range In conjunction with a healthy diet and exercise regimen
