About Black Ginger
A member of the ginger family native to Thailand, containing polymethoxyflavones (PMFs) as key bioactives. Several small RCTs show modest benefits for exercise performance (improved hand grip strength, reduced fatigue), sexual function in men, and peripheral blood flow. One RCT (Toda et al. 2016) showed improved metabolic markers in overweight subjects. Evidence base is small — most RCTs are from Thailand/Japan with small sample sizes (20–50 participants). No independent large-scale replication. Generally well tolerated in studies.
What Black Ginger supports
- Small RCTs show improved exercise performance and reduced fatigue
- May support peripheral blood flow and metabolic markers
How much Black Ginger to take
The RDA prevents deficiency. The effective range is what clinical trials used to actually move the outcome.
Effective
100–300
mg
RCTs use 100–300 mg/day of extract. Exercise performance studies used 100–150 mg/day. Sexual health studies used 100 mg/day.
Clinical evidence
Limited clinical evidence. Several small RCTs (20-50 participants) for exercise performance and sexual function — no large-scale independent replication
