Black ginger (Kaempferia parviflora) has been traditionally used in Southeast Asia for various health benefits, including as a tonic for physical strength and vitality. In recent years, there has been growing scientific interest in its effects on the muscular system. Preclinical studies, primarily in animals and in vitro, have suggested that extracts of black ginger may enhance skeletal muscle endurance and function. Proposed mechanisms include increased energy metabolism, improved mitochondrial biogenesis, and upregulation of pathways involved in muscle cell growth and differentiation, such as the activation of AMP-activated protein kinase (AMPK).

Some small-scale human studies have explored black ginger supplementation in the context of physical performance. For example, limited trials in healthy adults and elderly populations have reported modest improvements in grip strength and walking endurance. However, these studies are often limited by small sample sizes, short durations, and varying extract preparations. Currently, the evidence base is insufficient to firmly establish efficacy or optimal dosing for muscle support in humans.

In summary, while there is laboratory and early clinical evidence suggesting potential benefits of black ginger on muscle function, the overall quality and quantity of human research remain limited. More robust, large-scale clinical trials are needed to confirm its effects and mechanisms in supporting the muscular system.
