Ceylon cinnamon has significant clinical evidence for blood glucose modulation — one of the most accessible anti-diabetic spices in the database. The Black kitchen already uses it; APEX restores the clinical context.
Available at most grocery stores, Caribbean and Indian grocery stores, and online. More expensive than cassia but the medicinal quality warrants it.
Meta-analyses show Ceylon cinnamon reduces fasting blood glucose 11-29% and A1C by 0.36% in Type 2 diabetes. Cinnamaldehyde mimics insulin action at the cellular receptor level. CRITICAL DISTINCTION: Ceylon cinnamon (light, layered, crumbly sticks) is the medicinal form. Cassia (most grocery store cinnamon, hard sticks) contains higher coumarin that causes liver toxicity in high doses.
1/4 to 1/2 tsp Ceylon cinnamon daily in oatmeal, coffee, sweet potato, or as tea (simmer one stick in 2 cups water 10 minutes). Specify Ceylon when purchasing.
