PURE: >98% pure

SAFE: free of contaminants (such as Emodin and PAHs)

RELIABLE: Produced at metric ton scale with a consistent batch process in place

VERSATILE: off-white and odorless

The problem with PAHs in resveratrol

  • A significant quantity of resveratrol sold in the market today is Chinese-sourced resveratrol that is extracted from the Japanese Knotweed plant (aka Polygonum sp.)
  • Given the origin of polygonum-derived resveratrol, there is a serious risk that these products are contaminated with PAHs
  • In-house testing to monitor contaminants can be expensive and complex

Veri-te resveratrol eliminates your risk of PAH contamination

  • Evolva tested its own fermented Veri-te resveratrol and three Chinese-sourced resveratrol samples to analyze the levels of PAHs
  • Based on this analysis by an independent laboratory, there is a very high risk that polygonum-derived 98% trans-resveratrol will contain unacceptable levels of PAHs that exceed limits set in EU and California Prop 65 regulations
