WHY IT'S KETO-FRIENDLY
- Low net carbs: ~3g per 100g fits neatly into keto
- Good fiber: ~3.7g/100g supports digestion and lowers net impact
- Used in small amounts: spice means you’ll typically use teaspoons, not cups
- Capsaicin content: may modestly support thermogenesis and fat oxidation
- Versatile heat: hotter than jalapeño, milder than habanero—easy to dial in
- Bright, fresh flavor: boosts satisfaction and craveability without extra carbs
