Sirtmax is an extract from black turmeric (kaempferia parviflora) from Japan. Black turmeric is a popular herbal medicine in Thailand and Laos. Sirtmax is rich in potent antioxidant known as kaempferia polymethoxyflavonoids (KPMFs). KPMFs are proven to be effective in regulating glucose and lipid metabolisms. Sirtmax also delays onset of ageing-related diseases due to its anti-glycation property.
