Cinnamomum burmanii, commonly known as Indonesian cinnamon, has been investigated for its potential effects on blood glucose regulation and sugar cravings. The primary scientific rationale stems from studies on cinnamon species (including C. burmanii and C. cassia), which suggest that certain compounds, such as cinnamaldehyde and polyphenols, may influence glucose metabolism by improving insulin sensitivity and slowing carbohydrate absorption. These effects could, in theory, help stabilize blood sugar and reduce cravings for sweets.

However, the evidence is mixed and generally limited by study design and quality. Some small clinical trials and in vitro studies indicate modest reductions in fasting blood glucose and improvements in insulin sensitivity with cinnamon supplementation, but most research does not specifically address the effect on sugar cravings as a behavioral outcome. Additionally, many studies use different cinnamon species or extracts, making it hard to attribute effects solely to C. burmanii.

In summary, while there is a plausible mechanism and some low-to-moderate quality evidence that C. burmanii may influence glucose handling, direct evidence that it effectively reduces sugar cravings is weak. The current scientific support is best rated as modest (2/5), pending more rigorous, targeted clinical trials.
