Derived from fruits of Vaccinium myrtillus, Yosun Bilberry Extract is uniquely concentrated with Anthocyanins—a powerful antioxidants that gives extract powder deep purple color as the fruits.
While the terms are often used interchangeably, anthocyanins are the naturally occurring glycosides (bound to a sugar molecule) found in the raw fruit, while anthocyanidins are the sugar-free aglycone cores created during extraction. Standardized supplements typically express potency as either 36% Anthocyanins or 25% Anthocyanidins.
Bilberries vs. Blueberries
| Feature | Bilberry (Vaccinium myrtillus) | Blueberry (Vaccinium Cyanococcus) |
|---|---|---|
| Fruit Growth | Grows singly or in pairs on short stalks. | Grows in large, highly productive clusters. |
| Inner Flesh | Deep red-purple flesh that stains easily. | Translucent green-white inner flesh. |
| Flavor Profile | Intense, concentrated, and acidic/tart. | Milder and consistently sweet. |
| Antioxidants | Significantly higher Anthocyanins content throughout. | Higher Anthocyanidins content, while Anthocyanins mostly concentrated in skin. |
BOTANICAL ORIGIN: Vaccinium myrtillus
PLANT SOURCE: Fruits
APPEARANCE: Dark violet powder
AVAILABLE SPECIFICATIONS: 25%UV/Anthocyanins 36%HPLC
ANALYSIS METHOD: UV/HPLC
| Feature | Anthocyanins | Anthocyanidins |
|---|---|---|
| Chemical Definition | Glycoside (Core structure with attached sugar molecules) | Aglycone (Pure core structure without any sugar) |
| Natural State | Highly stable and water-soluble | Highly unstable and prone to rapid degradation |
| Occurrence | Found naturally in 100% of fresh, raw bilberries | Rare in nature; created via laboratory extraction |
| Supplement Labeling | Standardized to 36% HPLC | Standardized to 25% UV |
| Molecular Size | Larger and bulkier due to the attached sugar chains | Smaller and stripped down to the basic ring core |
| Digestion | Must be stripped of sugar by gut enzymes to be absorbed | Ready for absorption but highly sensitive to gut pH changes |
Bilberry Extract Anthocyanidins & Anthocyanins Primary Applications
Primary application of bilberry extract anthocyanins is improving eye health and visual function, particularly night vision, alongside supporting microvascular and circulatory health.
1. Vision support: Enhancing dark adaptation, visual acuity, and reducing eye fatigue.
2. Vascular protection: Strengthening capillaries and improving blood flow.
3. Antioxidant activity: Combating oxidative stress and reducing cellular inflammation.
Production process of Bilberry Extract Anthocyanidins & Anthocyanins:
Freezing preparation -> Milling -> Solvent Infusion -> Solvent Extraction ->Resin Adsorption -> Purification -> Concentration -> Spray drying -> Standardization & Quality Control -> Packaging
