Each capsule of ResveraSirt-HP supplies 250 mg of purified Trans Resveratrol with quercetin for its ability to slow the metabolism of resveratrol. Also included in this formula is IP6 (phytic acid or phytin), a 6-phosphate ester of inositol derived from rice. Effective at a wide pH range, IP6 is a strong metal chelator, and thus aids in stabilizing the formula. By using the purified form of Resveratrol, ResveraSirt-HP® does not cause the GI distress often associated with lesser grades of this material.
