Pine bark extract has moderate evidence for circulation and skin elasticity, with most clinical trials using 100–200 mg daily. At 100 mg per capsule, you're at the minimum studied dose — potentially enough for antioxidant support, though stronger results in trials came from the 150–200 mg range.
Here's what's worth knowing: the vast majority of published research used Pycnogenol, a patented extract with a defined proanthocyanidin content. This product doesn't specify its OPC standardization percentage, so the actual active compound content in your capsule is uncertain. Two pine bark extracts at "100 mg" can deliver very different amounts of the compounds that matter.
If you want to match what was actually studied in clinical trials, knowing the OPC standardization is important — and this label doesn't provide it.
