Consumers may purchase cinnamon pills at pharmacies and health food shops, and dosage recommendations vary from 1 to 2 grams daily, according to Healthline. Cinnamon is often added to food, but the amounts are usually not enough to show noticeable benefits in blood sugar levels.
Several types of cinnamon are available, and research shows that cassia cinnamon, also known as Chinese cinnamon, is the most effective type for controlling blood sugar levels, reports Healthline. Cinnamon is an alternative medicine that scientists are still exploring as a treatment for diabetes, and more studies are necessary. As of 2015, findings are mixed, existing research is insufficient, and the long-term effects are still uncertain.
Cinnamon is generally safe to consume. However, individuals should consult their doctor before taking cinnamon as a dietary supplement. Cinnamon may trigger allergic reactions in some individuals. Additionally, cassia cinnamon contains coumarin, which has anticoagulant properties. It may cause individuals who are already taking blood-thinning medications to become more susceptible to bleeding, cautions Healthline. Large amounts of cinnamon may also have adverse effects on individuals with liver problems, says WebMD.
If individuals decide to use cinnamon supplements, they should look for brands with a quality seal such as the NSF International, U.S. Pharmacopeia or ConsumerLab seal to ensure that they are getting a trustworthy product, suggests WebMD.
Cinnamon is not a replacement for regular diabetic care. Individuals with diabetes should continue to follow their medical treatment plans and make healthy lifestyle choices, advises Healthline.
