Benefits

The evidence-based benefits of *Kaempferia parviflora* include significant reductions in fasting blood glucose levels associated with metabolic syndrome, with a standardized mean difference of -0.88 in animal studies and -0.51 in human studies. It has also been shown to improve sexual function in individuals with erectile dysfunction, and enhance physical performance metrics such as cardiorespiratory fitness. Secondary benefits include antiobesity effects, where it has been observed to decrease body weight gain and reduce adipose tissue mass. Populations most likely to benefit include adults with metabolic issues or those seeking improved physical capabilities. Studies supporting these claims have demonstrated a clinical significance in these areas over several weeks of supplementation.

How it works

*Kaempferia parviflora* primarily operates through modulation of lipid metabolism, whereby it inhibits lipogenesis and stimulates lipolysis, improving insulin sensitivity alongside its antioxidant properties. These actions impact several body systems, especially metabolic and cardiovascular. The molecular targets of its polymethoxyflavones allow for interaction at the cellular level, though specific data on its absorption and bioavailability are limited.

Side effects
