Frequently Asked Questions

What is Cinnulin PF and how is it different from regular cinnamon?

Cinnulin PF® is a patented aqueous extract that concentrates the water-soluble type-A polyphenolic polymers — the most biologically active compounds in cinnamon — while removing fat-soluble coumarin, which can be hepatotoxic at high doses. Regular cinnamon powder contains lower concentrations of these active polymers and retains coumarin, limiting safe daily intake. Cinnulin PF® provides a standardised, concentrated, and safe dose.*

Does cinnamon extract really affect blood sugar?

Clinical studies on Cinnulin PF® have shown improvements in fasting blood glucose, HbA1c, and insulin sensitivity markers. The type-A polyphenols appear to activate insulin receptors and enhance glucose transport into cells through GLUT4 transporter upregulation. Results are most pronounced when combined with a healthy diet and regular exercise.*

Why is it important to use a coumarin-free cinnamon extract?

Coumarin is a naturally occurring compound in cinnamon (particularly Cassia/Chinese cinnamon) that has hepatotoxic potential at high doses. Regular intake of large amounts of cinnamon powder can deliver enough coumarin to raise liver enzyme levels over time. Cinnulin PF® removes the fat-soluble coumarin while retaining all the water-soluble active polyphenols, making it safe for daily supplementation.*

Can I take cinnamon extract if I am on diabetes medications?

Use caution. Cinnamon extract can lower blood glucose and may potentiate the effect of diabetes medications like metformin or insulin, potentially causing blood sugar to drop too low. If you take any blood glucose-lowering medication, consult your healthcare professional and monitor blood sugar carefully when starting cinnamon supplementation.
