Cayenne Pepper (Fruit)

Also known as: Capsicum annuum, Red pepper, Chili pepper, Capsaicin-rich pepper

B
Evidence

Cayenne pepper is a pungent fruit rich in capsaicin, an alkaloid compound with demonstrated thermogenic and anti-inflammatory properties. It is widely used to support circulation, metabolism, and digestive function.

Primary uses

  • Metabolic support and thermogenesis
  • Circulation and cardiovascular health
  • Pain management (topical or systemic)
  • Digestive function
  • Appetite regulation

How it works

  • Capsaicin activates TRPV1 receptors, increasing heat production and metabolic rate
  • Promotes peripheral blood flow and vasodilation
  • Modulates inflammatory cytokines and reduces prostaglandin production
  • Stimulates digestive secretions and may improve nutrient absorption

Dosage

Typical range
30-120 mg capsaicinoids (or 40,000 HU cayenne powder) daily
Timing
With meals (preferably with fat-containing foods to improve absorption)
With food
Strongly recommended with food to minimize GI upset and enhance bioavailability
Duration
Can be used long-term; tolerance may develop with continuous use, suggesting periodic breaks
Special populations
Caution in GERD, IBS, or inflammatory bowel conditions; avoid if pregnant/nursing without medical guidance

  • Allergy to nightshade plants

Evidence notes

Moderate clinical evidence supporting thermogenesis, pain relief (especially topical), and modest metabolic effects. Human RCTs demonstrate small but consistent improvements in energy expenditure and satiety. Heat units (HU) standardization helps ensure consistency.

Grade B: Some human trials support key claims; further confirmation needed.
