Formula snapshot
What is Quercetin and Trans Resveratrol?
Quercetin is a flavonol; trans-resveratrol is a stilbene. This formula combines both, with separate extract strengths and amounts stated so the combined weight is not mistaken for the active content.
See the actives behind the extract weight.
Each capsule contains 200mg of 98% quercetin extract and 200mg of 50% trans-resveratrol extract. That represents approximately 196mg quercetin plus 100mg trans-resveratrol. Two capsules double those amounts.
