Cinnamon (The Insulin Controller)
Also Known As: Cinnamomum Verum (Ceylon), Cinnamomum Cassia
Compound Type: Insulin Mimetic / Antioxidant / Vascular Protector
Cinnamon is often ignored in male enhancement circles, but it solves a critical problem: Insulin Resistance. High blood sugar is one of the leading causes of Erectile Dysfunction because excess glucose acts like “shards of glass” in your blood vessels, scarring the delicate endothelial lining of the penis.
Cinnamon acts as an insulin mimetic, helping your body shuttle sugar into muscle cells rather than letting it float in the blood causing damage. By improving insulin sensitivity, you preserve the long-term health of your penile arteries.
How Does Cinnamon Help Size?
It protects the blood vessels from glycation (sugar damage) and lowers inflammation, ensuring your arteries remain flexible for maximum expansion.
The Science: Cassia vs. Ceylon
1. Insulin Sensitivity:
A study in Diabetes Care found that taking just 1g of cinnamon per day reduced blood sugar levels by up to 29% in just 40 days. Lower blood sugar means less plaque buildup in the penile arteries.
2. Nitric Oxide Preservation:
High insulin levels inhibit the production of Nitric Oxide. By lowering insulin resistance, Cinnamon indirectly allows your body’s natural NO production (and supplements like Citrulline) to work more efficiently.
3. The Coumarin Danger (Important):
Not all cinnamon is the same. The common “Cassia” cinnamon found in grocery stores contains high levels of Coumarin, which can be toxic to the liver in high doses. You must choose Ceylon Cinnamon (“True Cinnamon”) for daily supplementation.
Check your bottle.
If your supplement just says “Cinnamon Bark” without specifying the type, it is likely the cheap Cassia variety. Do not exceed 1-2g of Cassia per day. Ceylon can be taken safely in higher doses.
✔ The Verdict: VASCULAR DEFENSE
3/5 Stars. This is “defense” for your penis. If you consume sugar or carbs, Cinnamon is mandatory to prevent the vascular damage that leads to shrinkage and ED later in life.
