Nutricost Resveratrol 700mg
3
A high-dose standardized extract delivering 700 mg of Japanese knotweed extract per 2-capsule serving, standardized to 50% trans-resveratrol (350 mg). Third-party tested, NSF-certified GMP facility.
Why It Stands Out
Highest resveratrol dose per serving in this comparison. Third-party testing adds quality assurance. However, the high standardization means this is a concentrated resveratrol product, not a whole-herb knotweed supplement as specified in the botanical protocol.
