Product Description

Loquat Leaf Extract (Corosolic Acid Powder) – High-Purity Natural Support for Metabolic Health

Our Loquat Leaf Extract, also referred to as Eriobotrya Japonica Leaf Extract, is standardized to a high level of corosolic acid, the main bioactive compound responsible for supporting glucose metabolism. Corosolic acid works by enhancing cellular glucose uptake and promoting balanced energy use, making it a sought-after ingredient in dietary supplements and functional nutrition products.

In the current market, demand for Loquat Leaf Extract is growing steadily, particularly for powders with consistent corosolic acid content, as manufacturers require reliable quality for effective formulations. While many extracts on the market vary in potency or purity, our product offers precision-controlled extraction, ensuring each batch maintains stable corosolic acid levels without compromising natural plant compounds.

What sets Botanical Cube apart is our ability to combine this high-purity extract with flexible OEM solutions. We can provide tailored formulations, dosage customization, and private-label packaging designed specifically for corosolic acid products. This allows brands to create unique offerings while maintaining consistent efficacy and compliance with quality standards – something standard extracts alone cannot guarantee.
