Antioxidant
Sorghum bicolor Extract (Leaf) with Polyphenols
Also known as: ReDaxin™, Red Sorghum Bioflavonoid Complex, Sorghum leaf extract, Red sorghum extract
ReDaxin™ is a standardized sorghum leaf extract rich in polyphenols and bioflavonoids traditionally used in Asian cuisines for potential antioxidant and metabolic support. Limited clinical research exists on this specific extract in humans, though sorghum is recognized as a polyphenol-rich grain with antioxidant properties.
Primary uses
- Antioxidant support
- Metabolic health
- General wellness
How it works
- Polyphenol-mediated free radical scavenging
- Potential modulation of antioxidant enzyme systems
- Anti-inflammatory signaling through flavonoid pathways
Dosage
- Typical range
- 300–600 mg daily (standardized to 20% polyphenols)
- Timing
- With meals for optimal absorption
- With food
- Recommended; polyphenols absorb better with dietary fat
- Duration
- Typical use as a daily antioxidant supplement; long-term safety data is limited
- Special populations
- Pregnant/nursing women should consult healthcare provider; safety in children not established
Forms
- Capsule· 70/100
- Powder· 70/100
Safety
Common side effects
- Generally well-tolerated; mild gastrointestinal effects possible at high doses
Contraindications
- Known sorghum allergy or grass pollen sensitivity
- Use with caution in individuals with polyphenol-sensitive conditions
Evidence notes
While sorghum is recognized as a polyphenol-rich food source with in vitro antioxidant capacity, clinical human trials specifically evaluating ReDaxin™ or sorghum leaf extract at standardized doses are limited. Evidence relies primarily on in vitro studies, traditional use, and general polyphenol biology rather than robust RCT data.
Grade C: Mostly observational or small trials; mechanism is plausible but unproven at scale.
