Overview
Cinnamon is a widely used spice derived from the bark of Cinnamomum species. It has been studied for its potential effects on blood glucose regulation, lipid metabolism, and inflammation.
In a longevity context, cinnamon is particularly relevant due to its potential to support glycaemic control and cardiometabolic health.
Key Compounds
Cinnamon contains several bioactive compounds, including: - Cinnamaldehyde - Polyphenols - Procyanidins
These compounds are thought to influence insulin signalling and glucose metabolism.
Why We Include It
1. Blood glucose control Cinnamon has been shown to reduce fasting blood glucose in several human trials.
2. Lipid profile Some studies report reductions in triglycerides and LDL cholesterol.
3. Insulin sensitivity Cinnamon may improve insulin signalling and glucose uptake.
4. Dietary diversity Adds flavour and polyphenol diversity to the formulation.
Evidence & References
Study 1 — Type 2 Diabetes Glycaemic Control
Type: Randomised controlled trial Population: Adults with type 2 diabetes Intervention: 1, 3, or 6 g cinnamon daily Duration: 40 days
Key Finding: Cinnamon reduced fasting blood glucose, triglycerides, LDL cholesterol, and total cholesterol.

Summary
Cinnamon is a well-studied spice with evidence supporting its role in blood glucose regulation and cardiometabolic health.
Its effects are generally modest but consistent, making it a useful component of a broader longevity-focused dietary approach.
