Description
The standardized extract of Banaba leaf (Lagerstroemia speciosa), a Southeast Asian medicinal tree. Standardized to corosolic acid content, the principal active triterpenoid responsible for blood-sugar-support activity. Used in diabetes-support and weight-management dietary supplements globally.
Light to dark brown free-flowing powder. Limited water solubility; freely soluble in alcohol.
We supply food-grade Banaba Leaf Extract from manufacturers in China holding ISO, Halal, Kosher and other certifications relevant to the product and production.
Common market grades include 1 percent Corosolic Acid (cost-effective baseline), 2 percent Corosolic Acid (standard supplement grade), 5 percent Corosolic Acid (premium grade matching the clinically-studied dosing), 18 percent Corosolic Acid (high-end concentrated grade), and 98 percent Pure Corosolic Acid (pharmaceutical-grade isolated active).
Bulk and reduced-MOQ shipments. Batch-level COA covering corosolic acid content (HPLC), total triterpenes, residual solvents, heavy metals, pesticides, and microbiology.
Introduction
Banaba has been used in traditional Filipino and Southeast Asian medicine for centuries for blood-sugar regulation, kidney complaints, and weight management. The plant is sometimes called 'plant insulin' in traditional Filipino medicine due to its observed blood-sugar effects.
Industrial production proceeds by ethanol or hydroalcoholic extraction of dried Banaba leaves, followed by purification and standardization to defined corosolic acid content.
Recognized as a permitted food ingredient by the U.S. FDA, the European Food Safety Authority, and equivalent regulators worldwide.
Corosolic acid acts on glucose transporter mechanisms with effects similar to but milder than pharmaceutical insulin sensitizers. Clinical evidence in humans includes several small randomized controlled trials showing modest reductions in fasting and post-prandial blood glucose at 10 to 32 mg corosolic acid per day, supporting the blood-sugar-management positioning.
Strategic positioning targets the diabetes-support and weight-management supplement segments, frequently formulated alongside Berberine, Cinnamon, and Gymnema as part of comprehensive blood-sugar combinations.
Where it is used
- Blood-sugar-management dietary supplements: diabetes-support formulations (the dominant commercial application)
- Weight-management supplement formulations
- Metabolic-syndrome support combination formulations
- Sports nutrition: glucose-disposal and recovery-positioned products
- Traditional Filipino and Southeast Asian medicine product formulations
- Pharmaceutical research applications for type 2 diabetes
- Veterinary applications for diabetes support in companion animals
