**U.S. Patent Applications 13/213,313 and 13/196,390
Unlike single-ingredient alternatives, Proflavanol C200 uniquely combines a high dose of top-quality grape seed extract with a wide spectrum of antioxidants and multiple sources of vitamin C for complex, multi-pronged health support.*
This research-backed formula uses cellular science to support the body inside and out.
Promotes healthy, youthful-looking skin*
Using our Hybrid Technology, we’re able to combine multiple ingredients that otherwise aren’t compatible into a single tablet for easy absorption and simple wellness support. This includes Poly C, our proprietary blend of multiple vitamin C sources.
As of 2025, our formulation includes a spectrum of additional flavonoids that provide broader antioxidant support against the effects of oxidative stress: Hesperidin, Quercetin, Green Tea Extract (EGCG), and Bilberry Extract.
This means better support across the board—heart health, skin health, immune function, and support for healthy aging.*
Take one to four Proflavanol C200 tablets each day, preferably with food.
Nutrition adjustments typically take 2–8 weeks to have noticeable effects. Commit to your supplement routine for at least 90 days. Common reports include:
