Greenherb supplies a premium, scientifically-validated Cinnamon Bark Extract, derived from the dried inner bark of Cinnamomum verum J. Presl (syn. Cinnamomum zeylanicum), known as true cinnamon or Ceylon cinnamon, as well as Cinnamomum cassia (cassia) depending on specification. Our cinnamon bark extract is carefully processed to preserve its full spectrum of bioactive compounds, primarily cinnamaldehyde, cinnamic acid, and proanthocyanidins (type-A polymers). This potent cinnamon bark extract powder delivers clinically-supported benefits for healthy blood sugar metabolism, cardiovascular wellness, and antioxidant protection, offering a time-honored spice with extensive modern scientific validation for global nutraceutical, dietary supplement, and functional food markets.
We support global B2B customers with consistent quality, scalable supply, and comprehensive analytical documentation, enabling the development of evidence-based products that leverage this versatile botanical's remarkable therapeutic properties.
Standardized for High-Potency Cinnamaldehyde – Our cinnamon bark extract is precisely standardized to guarantee consistent levels of cinnamaldehyde (typically 1.5%, 2%, 3%, 5%, or 10%), the primary volatile oil responsible for its characteristic warm, sweet flavor and its insulin-sensitizing, anti-inflammatory, and antimicrobial properties. This ensures reliable potency in every batch of cinnamon bark extract powder, making it a trusted cinnamon bark supplement for metabolic health.
Clinically-Validated Blood Sugar & Insulin Support – Multiple human clinical trials and meta-analyses have demonstrated that cinnamon bark extract significantly reduces fasting blood glucose, improves insulin sensitivity, and helps maintain healthy HbA1c levels within normal ranges. The active compounds enhance insulin receptor signaling and inhibit alpha-glucosidase activity, supporting healthy postprandial glucose metabolism.
Rich in Type-A Proanthocyanidins – Beyond cinnamaldehyde, our cinnamon bark powder contains unique type-A oligomeric proanthocyanidins (procyanidin A1, A2, B1, B2, C1) that provide potent antioxidant protection, support healthy inflammatory balance, and complement the metabolic effects of cinnamaldehyde. These compounds are distinct from the type-B proanthocyanidins found in other botanicals like grape seed or pine bark.
Supports Healthy Lipid Profiles & Cardiovascular Wellness – Clinical research indicates that cinnamon bark extract helps maintain healthy cholesterol and triglyceride levels within normal ranges, supporting overall cardiovascular health. The combination of cinnamaldehyde and proanthocyanidins helps reduce oxidative stress in vascular tissues and supports healthy blood pressure already within normal range.
Potent Antioxidant & Anti-Inflammatory Protection – Cinnamon bark extract demonstrates significant free radical scavenging activity, with an ORAC value comparable to many superfruits. It helps modulate pro-inflammatory mediators (including NF-κB and COX-2), supporting the body's natural ability to manage inflammation without suppressing necessary immune responses.
Natural Antimicrobial & Digestive Comfort – Cinnamon bark has a long traditional use for digestive health, with cinnamaldehyde exhibiting antimicrobial activity against various bacteria and fungi. It may help support a healthy gut environment and reduce occasional digestive discomfort.
Sustainably Sourced from Premium Growing Regions – Our cinnamon bark is sourced from mature trees in Sri Lanka (Ceylon) and other certified cultivation regions, ensuring optimal bioactive compound development, sustainable harvesting practices, and authentic botanical identity.
Greenherb's Cinnamon Bark Extract captures the therapeutic essence of one of the world's oldest and most treasured spices. For thousands of years, cinnamon has been prized not only for its warm, sweet flavor but also for its remarkable medicinal properties—from ancient Egyptian embalming practices to traditional Chinese and Ayurvedic medicine . Modern science has now validated this ancient wisdom, revealing that cinnamon bark contains a sophisticated profile of cinnamaldehyde and type-A proanthocyanidins that work synergistically to support healthy blood sugar metabolism, improve insulin sensitivity, and provide potent antioxidant protection . What makes cinnamon bark extract particularly valuable for metabolic health is its ability to mimic insulin activity, enhancing glucose uptake into cells without overstimulating insulin secretion . Our standardized cinnamon bark extract powder delivers these benefits in a consistent, concentrated form, making it the ideal choice for brands developing advanced products in the blood sugar support, metabolic wellness, and cardiovascular health categories. Whether you need a cinnamon bark supplement for daily glucose management or pure cinnamon bark powder for functional foods, our ingredient provides the clinical credibility that today's discerning brands demand.

Cinnamon Bark Extract is utilized for its scientifically-documented, clinically-validated health benefits:
Supports Healthy Blood Sugar & Insulin Sensitivity*: Cinnamon bark extract enhances insulin receptor kinase activity, increases glucose transporter (GLUT4) translocation, and inhibits alpha-glucosidase activity, resulting in reduced fasting blood glucose, improved postprandial glucose control, and lower HbA1c levels in individuals with elevated blood sugar. Meta-analyses of randomized controlled trials confirm significant glucose-lowering effects .
Supports Healthy Cholesterol & Lipid Profiles*: Multiple clinical studies demonstrate that cinnamon bark extract helps maintain healthy total cholesterol, LDL cholesterol, and triglyceride levels within normal ranges while supporting healthy HDL cholesterol, contributing to comprehensive cardiovascular wellness .
Provides Potent Antioxidant & Anti-Inflammatory Protection*: The type-A proanthocyanidins and cinnamaldehyde provide powerful free radical scavenging activity, protecting cells from oxidative stress and helping to modulate pro-inflammatory mediators (NF-κB, COX-2, iNOS) .
Promotes Cardiovascular & Endothelial Health*: Cinnamon bark extract helps maintain healthy blood pressure already within normal range, improves endothelial function, and reduces oxidative stress in vascular tissues, supporting overall heart health .
Supports Digestive Comfort & Healthy Gut Environment*: Traditional use of cinnamon bark for digestive health is supported by research showing antimicrobial activity against various pathogens and potential prebiotic-like effects on beneficial gut bacteria .
Provides Natural Antimicrobial & Preservative Properties*: The cinnamaldehyde content exhibits broad-spectrum antimicrobial activity, making cinnamon bark extract valuable for natural preservation applications and oral health formulations .
