Our bitter orange extract nobiletin powder (also known as sour orange extract or sour orange flavonoid complex) is standardized with highly purified nobiletin, a polymethoxylated flavonoid extracted from the peel of bitter orange (Citrus aurantium). Nobiletin has been clinically demonstrated to possess dual benefits for metabolic health, cognitive function, anti-inflammatory, and antioxidant properties.
Global demand for bitter orange extracts rich in nobiletin is surging, particularly in functional foods, nootropics, and metabolic health formulations. As a high-quality citrus flavonoid, it offers advantages over standard synephrine bitter orange extracts, including a safer, less irritating, and broader clinical application. Our proprietary extraction technology ensures a nobiletin content of ≥60% as determined by HPLC, preserving complementary bioactive compounds such as tangeretin and citrullin, resulting in improved bioavailability and potency compared to isolated nobiletin. In addition, we support OEM customization services, including customized particle size and formulations optimized for beverage/softgel solubility.
Guaranteed nobiletin content ≥60% (HPLC verified), a full spectrum of hesperidin components, and the preservation of synergistic flavonoids such as tangeretin (≥5%) and bitter orange (≥3%) for enhanced bioavailability.
Low-temperature ethanol extraction preserves heat-sensitive bioactive components, and specialized emulsification technology increases absorption by 2-3 times compared to standard powders.
Customized particle size (60-100 mesh) allows for optimal blending into capsules, tablets, or granules. Pre-formulated anti-aging complexes (such as nobiletin + NMN) accelerate your product development.

Used in capsule or tablet form to promote fat metabolism and help maintain a healthy weight.
Added to formulations designed to improve memory, learning, and neuroprotection.
Due to its antioxidant properties, it is used in anti-aging or skin-brightening formulations.
*Note: Dosage should always comply with local regulations and safety assessments.
Generally, it is safe when taken at recommended doses. It is extracted from natural citrus peels and is a widely recognized bioflavonoid.
Research suggests that when combined with diet and exercise, it can promote healthy lipid metabolism and fat management.
Nobiletin is slightly soluble in water but more soluble in ethanol or oil. Our specialized extraction can be optimized for specific solubility needs.
When stored in a cool, dry place away from direct sunlight, the shelf life is typically 24 months.
Yes, we offer flexible OEM solutions and custom blending services to help brands accelerate their product development.
Every batch is tested via High-Performance Liquid Chromatography (HPLC) to ensure the nobiletin content meets or exceeds 60%.
