localized pain relief via topical capsaicin; minor metabolic effects from oral use
Common dosing range
Topical 0.025–0.075% capsaicin; oral capsules ~0.5–2 mg capsaicinoids
When to expect effects
Topical: days to weeks; oral thermogenesis: acute
Watch out for
Burning sensation; avoid eye/mucous-membrane contact and active peptic ulcer
What is it
Cayenne pepper is the dried fruit of Capsicum annuum, supplying capsaicinoids (capsaicin, dihydrocapsaicin) responsible for its heat, plus carotenoids and vitamin C.

topical pain relief
Supplement benefitTopical capsaicin desensitizes TRPV1-bearing sensory neurons by depleting substance P, and meta-analyses of randomized trials support reduced pain in osteoarthritis and several neuropathic pain conditions. An initial burning sensation is expected and fades with continued use. This is a well-established symptomatic effect at the application site.
Bottom line: Topical capsaicin is a well-evidenced option for localized osteoarthritic and neuropathic pain.
thermogenesis and short-term satiety
Biomarker supportOral capsaicinoids activate TRPV1 in the gut, producing small, measurable increases in energy expenditure and modest short-term reductions in appetite in controlled studies. The effects on body weight in trials are small and inconsistent. Treat this as a minor metabolic nudge, not a weight-loss tool.
Bottom line: Oral capsaicinoids give a small thermogenic and satiety effect, but minimal impact on actual weight.
Evidence is mixed
Metabolic and appetite effects are measurable acutely, but translation into meaningful weight loss is weak and inconsistent.
