Cinnamomum Cassia Bark Extract
Also known as: Cassia cinnamon, Chinese cinnamon, Cinnamomum aromaticum, Cinnamomum cassia
Overview
Cinnamomum cassia, commonly known as cassia cinnamon, is a spice native to China and Southeast Asia, renowned for its fragrant bark. Traditionally, it has been utilized in culinary applications and herbal medicine. Its notable health benefits include potentially regulating blood sugar levels and supporting cardiovascular health. The primary active compound, cinnamaldehyde, is credited for these beneficial effects. Existing research indicates a role for cassia cinnamon in diabetes management and hypertension, although the variability in outcomes suggests that further investigation is warranted to better understand its effectiveness across diverse populations. The extract is primarily available in powdered form or as a concentrated extract for supplement use.
Benefits
Research indicates that Cinnamomum cassia offers significant benefits, particularly in blood sugar control and blood pressure regulation. Several studies demonstrate that cassia cinnamon can lower fasting blood glucose levels by approximately −1.55 mmol/L and reduce diastolic blood pressure by about −0.93 mmHg. Additional secondary benefits may include aiding weight management, particularly in individuals with type 2 diabetes or pre-diabetic conditions. The strongest evidence appears in populations engaged in long-term supplementation. These findings highlight cassia cinnamon's potential as an effective adjunct in glycemic and cardiovascular management.
How it works
The beneficial effects of Cinnamomum cassia are mainly linked to cinnamaldehyde, which improves insulin sensitivity and helps regulate blood pressure. This compound interacts with insulin receptors and promotes vasodilation, thereby enhancing metabolic and cardiovascular health. While its absorption and bioavailability in the gastrointestinal tract require more research, preliminary insights suggest that cinnamaldehyde is sufficiently absorbed when consumed in significant amounts.
Side effects
Cinnamomum cassia is generally considered safe when consumed in moderation, with few commonly reported side effects. A small percentage (1-5%) of users may experience gastrointestinal upset, while allergic reactions are rare (less than 1%). High dosages pose additional risks, particularly for pregnant individuals due to potential uterine stimulation. Individuals with bleeding disorders should exercise caution, as cassia cinnamon might exhibit antiplatelet effects, compromising blood clotting. Furthermore, those taking diabetes medications should monitor their blood sugar closely, as cassia cinnamon may enhance the effects of these treatments.
Dosage
The recommended dosage range for Cinnamomum cassia varies from 1 to 6 grams per day, tailored to specific health objectives. For blood glucose management, a minimum effective dose of 1-2 grams is advisable, while higher doses may be utilized for other health impacts. Taking cassia cinnamon with meals can help mitigate potential gastrointestinal discomfort. It is generally recommended that daily intake exceeds 6 grams only with professional guidance due to the increased risk of adverse effects. The most common form used is powdered extracts, where bioavailability may be improved when consumed with food.
