If you're looking for metabolic and blood sugar support, this liquid extract delivers **Cinnamon Bark** (Cinnamomum cassia) at 634mg per squeeze in a concentrated tincture format. Cinnamon has been studied for blood sugar management — a meta-analysis of RCTs found modest reductions in fasting glucose at doses of 1,000–6,000mg of whole cinnamon powder daily.

The challenge with liquid extracts is comparing dosage to the clinical research, which primarily used dried powder or standardized capsules. The label states an extraction rate of 175mg herb per 0.7mL with a 1:4 dry herb-to-menstruum ratio. Even at 2–4 servings per day as directed, you're likely below the doses used in most blood sugar trials. The cassia species also contains coumarin, which can be a concern at high daily intakes over time.

Cinnamon research overall shows small effects on blood sugar, and the evidence is mixed. If metabolic support is your primary goal, the clinical backing here is limited compared to nutrients with stronger trial data.
