Black ginger (Kaempferia parviflora) has gained attention in recent years for its potential to support muscle function, including muscle tone and strength. Scientific investigations, primarily preclinical and a few human clinical trials, have examined its effects on muscle performance. The main bioactive compounds in black ginger—polymethoxyflavones—are thought to modulate energy metabolism, mitochondrial function, and muscle contraction pathways.

A handful of small-scale human studies and animal experiments suggest that black ginger extract supplementation may improve physical fitness, muscle endurance, and muscle strength. For example, research published in Evidence-Based Complementary and Alternative Medicine (2018) showed that daily supplementation improved physical fitness and muscular endurance in healthy men. Mechanistically, black ginger is believed to enhance nitric oxide production, which could improve blood flow and nutrient delivery to muscles, potentially supporting muscle tone.

Despite these promising results, the overall body of evidence remains limited. Most studies are small, short-term, or conducted in animals. There is a lack of large, robust clinical trials specifically addressing black ginger’s effect on muscle tone in populations with muscle weakness or atrophy. Therefore, while there is some scientific validation for its use to support muscle function, the evidence is preliminary and not yet conclusive.

In summary, black ginger is being investigated as a muscle tonic based on early scientific evidence, but further research is needed to confirm its efficacy and establish appropriate usage guidelines.
