How to Choose

Understanding Capsaicin: Science and Supplementation

Capsaicin is the naturally occurring alkaloid responsible for the pungency in chilli peppers, and modern research has illuminated its potential role in metabolic health. When consumed as a supplement, capsaicin activates certain pain receptors in your body, triggering a temporary increase in heart rate and energy expenditure—a process known as thermogenesis. This elevation in metabolic rate can contribute to modest enhancements in fat burning, particularly when combined with regular physical activity. The scientific evidence supporting capsaicin supplementation has accumulated through numerous peer-reviewed studies, though results typically show modest effects ranging from 50 to 100 additional calories burned daily. Importantly, tolerance can develop with regular use, meaning cycling supplementation may preserve its effectiveness. The quality of capsaicin supplements varies considerably; standardised extracts (where capsaicinoid content is guaranteed) offer superior predictability compared to whole pepper powders.
