Blueberry Extract (Vaccinium angustifolium)
Also known as: Wild blueberry extract, Lowbush blueberry extract, Vaccinium angustifolium extract, Blueberry fruit extract
Blueberry extract is a concentrated source of anthocyanins and polyphenols with demonstrated antioxidant and anti-inflammatory properties. Research supports potential benefits for cognitive function, cardiovascular health, and eye health, though clinical evidence in humans remains moderate.
Primary uses
- Cognitive function and memory
- Cardiovascular health
- Antioxidant support
- Eye health
- Anti-inflammatory support
How it works
- Anthocyanin-mediated antioxidant activity
- Free radical scavenging
- Anti-inflammatory signaling
- Vascular endothelial function improvement
Dosage
- Typical range
- 250–500 mg daily (standardized extract)
- Timing
- With meals for optimal absorption
- With food
- May be taken with or without food; food may enhance anthocyanin absorption
- Duration

Evidence notes
Good evidence from multiple RCTs and observational studies supporting antioxidant efficacy and cognitive/cardiovascular benefits. Well-established anthocyanin content and bioavailability. Grade B rather than A due to some inconsistency in clinical outcomes and limited mechanistic certainty in humans.
Grade B: Some human trials support key claims; further confirmation needed.
