Trans-Resveratrol vs Regular Resveratrol: Why the Form Matters
Most resveratrol supplements are not delivering what the longevity research actually studied. Trans-resveratrol is the pure bioactive isomer responsible for sirtuin activation and cellular stress resistance. Regular resveratrol is often a mixed isomer product with significantly less biological activity. And even with the right form, poor bioavailability means most of it gets cleared before reaching target tissues. That's why pairing 150mg trans-resveratrol with 75mg quercetin isn't optional. It's what makes the compound actually work.
