Product Description

Bilberry Extract is a concentrated powder of characteristic active ingredients refined from specified botanical raw materials, with anthocyanins as the main active component. It meets quality standards of anthocyanins 25%-36% (HPLC), offering multiple benefits including immune function enhancement and regulation, anti-aging, and eye health support. It is widely used in health supplements, functional foods, and personal care products. Bilberry/Blueberry Extract is sourced from premium Nordic-imported or Northeast China raw materials, with anthocyanin content ≥20%, making it an ideal raw material for eye health and antioxidant product development.

Bilberry and blueberry are the best-selling berry-type health supplement ingredients worldwide. Northern Europe and North America are the primary production regions, with successful cultivation in Northeast China and Shandong province. The global Bilberry and blueberry market exceeds USD 10 billion. Bilberry extract, rich in anthocyanins, is particularly valued in the eye health segment – often positioned alongside lutein and zeaxanthin in vision-support formulations. European bilberries (Vaccinium myrtillus) contain significantly higher anthocyanin levels than cultivated blueberries, making them the preferred raw material for high-potency extracts.

Bilberry Extract powder product adopts low-temperature extraction, reduced-pressure concentration, and spray drying (or freeze-drying) processes. The low-temperature technique efficiently extracts bilberry flavonoids and polyphenol active components while preserving antioxidant activity. Different bilberry extraction ratios and standardization levels can be customized according to customer requirements.

Basic Information

Standard Specifications (COA)

The following specifications are reference values only; actual values are subject to each batch COA report.

Botanical Source Description

The raw material of this product is the dried ripe fruit of Vaccinium myrtillus, Family: Ericaceae. Primary growing regions include Northern Europe (Sweden, Finland, Russia), North America (USA, Canada), and Northeast China. Bilberry and blueberry are both anthocyanin-rich berries, renowned as “superfoods.” The main active components are anthocyanins (cyanidin-3-glucoside, delphinidin-3-glucoside, etc.) and phenolic acid compounds.

Core Efficacy

Bilberry (Vaccinium myrtillus) extract has the most robust evidence-based medical support for vision protection and microcirculation improvement among botanical ingredients. Its anthocyanin content (mainly cyanidin-3-glucoside) reaches 25%-35%, significantly higher than common blueberries. A multicenter randomized controlled trial (RCT) demonstrated that daily supplementation with 500mg bilberry extract for 8 weeks improved night vision acuity by 23% (P<0.001) and shortened dark adaptation time by 15% in pilots (Journal of Ophthalmology, 2015; 2015: 294785). Mechanism studies have shown that anthocyanins inhibit aldose reductase (IC50 = 3.2 μM), reducing retinal sorbitol accumulation, while upregulating eNOS expression to increase NO production and improve fundus microcirculation. In terms of neuroprotection, bilberry anthocyanins can cross the blood-brain barrier and reduce Aβ deposition in the hippocampus of APP/PS1 mice by 28% (P<0.05), alleviating oxidative stress via the Nrf2/HO-1 pathway (Molecular Nutrition and Food Research, 2017; 61: 1600812). Additionally, bilberry extract has demonstrated significant antioxidant and anti-inflammatory effects in cardiovascular health applications, making it a versatile ingredient for comprehensive health formulations.

Application Directions & Recommended Dosage

Recommended Daily Dosage Reference

• General eye health support: Follow product specifications and formulator recommendations; typical bilberry extract dosage 80-160mg/day (standardized to 25% anthocyanins)
• Performance/athletic recovery: 30-60 minutes before training is optimal for antioxidant benefits
• Personal care/skincare: Addition level depends on the specific product; recommended 0.1-2.0% w/w

Note: For eye health formulations, bilberry extract is often combined with lutein, zeaxanthin, and omega-3 for synergistic effects

Other Precautions

• Anthocyanin-containing extracts are sensitive to light, heat, and pH changes – maintain stable storage conditions to preserve color and potency
• Anthocyanins are pH-sensitive – color shifts from red (acidic) to blue/purple (alkaline); consider pH buffering in liquid formulations
• Pregnant women, nursing mothers, children, and individuals with bleeding disorders should consult a healthcare provider before use. High doses may have mild blood-thinning effects
• Bilberry extract Anthocyanin product information is for B2B purchasing and technical reference only and does not constitute medical or health claims for end consumers
• People with diabetes should consume this in small amounts whilst ensuring their blood glucose levels remain stable; the natural sugars in the extract may cause fluctuations in blood glucose levels, so blood glucose levels should be monitored at the same time.
• End product claims must comply with local regulations
