Cayenne is a type of Capsicum annuum, made by grinding dried chili peppers into a fine powder. It packs a much higher concentration of capsaicin than bell peppers or paprika. That heat makes it the go-to capsicum form when people want stronger effects on metabolism and circulation.
People take cayenne to support digestion and blood flow. The idea is that capsaicin stimulates digestive enzymes and nudges the cardiovascular system. Users also reach for it as a gentle metabolic lift. It comes in capsules, powders, and tinctures. Always take cayenne with food to avoid stomach upset, and look for enteric-coated capsules if plain powder bothers you.
Capsaicin can irritate the gut. If you have a sensitive stomach or any history of ulcers, approach it carefully. Cayenne may also interact with blood-thinning medications. Start low, see how you feel, and adjust from there.
