Terry Naturally Clinical OPC: The tannin-free OPC supplement

OPC is one standout ingredient. However, most OPCs are difficult for our body to absorb, including some formulas that contain French grape seed extract VX1. That’s where Terry Naturally Clinical OPC stands out — it’s tannin-free, which boosts its absorbability!*

Tannins are naturally found in grape skin, seeds, and stems. Our body has difficulty absorbing them because they have a high molecular weight. Fortunately, Terry Naturally sources a unique French grape seed extract VX1 with a low molecular weight, making it gentle on our bodies.*
