Also known as: Wild Blueberry, Lowbush Blueberry, Northern Highbush Blueberry, Blueberry, Vaccinium myrtillus, Vaccinium angustifolium

Overview

Wild blueberries, scientifically known as *Vaccinium angustifolium*, are small, nutrient-dense berries native to North America. They are esteemed for their high content of polyphenolic compounds, particularly anthocyanins, which impart potent antioxidant properties. Available in various forms—including fresh, frozen, powdered, and as extracts or juices—wild blueberries are recognized for their potential physiological benefits. Systematic reviews and meta-analyses indicate they may support cardiovascular health, enhance cognitive function, and assist in managing aspects of metabolic syndrome. The strength of evidence regarding these positive effects is moderate to high, especially in lipid profile improvements and blood pressure regulation, with significant cognitive function benefits observed in children.

Benefits

Significant research indicates that wild blueberry supplementation can improve lipid profiles, contributing to cardiovascular disease prevention. Studies show reductions in total cholesterol levels by -0.24 mmol/L and LDL cholesterol by -0.20 mmol/L. Acute consumption has been linked with cognitive enhancements in children, particularly for verbal memory and attention tasks. Evidence suggesting benefits for alleviating depression and anxiety in adolescents remains limited. Overall, the moderate effect sizes for lipid improvements strongly advocate the use of wild blueberries for supporting cardiovascular health.

How it works

The health benefits of wild blueberries are largely attributed to their high polyphenol content, specifically anthocyanins, which exhibit antioxidant, anti-inflammatory, and vasodilatory effects. These compounds improve endothelial function, reducing oxidative stress and enhancing insulin sensitivity. By engaging with critical biological pathways related to cardiovascular and metabolic health, anthocyanins also modulate inflammatory responses and vascular health, thereby positively impacting overall wellness.

Side effects

Wild blueberry supplements are considered safe, with common side effects reported in less than 5% of users. Mild gastrointestinal discomfort may occur in 1-5% of consumers, while serious side effects are rare (<1%). While detailed information on drug interactions is limited, caution is advised when used alongside medications that share metabolic pathways. Individuals with known berry allergies or gastrointestinal conditions should consult a healthcare provider prior to use. Pregnant or breastfeeding women should also seek professional advice, despite the absence of specific contraindications.

Dosage

For wild blueberry supplements, the recommended daily dosage typically ranges from 250 mg to 1 gram of freeze-dried powder, with optimal dosages between 250 mg and 500 mg, providing approximately 200-400 mg of anthocyanins. Although rigorous upper safety limits for dosages exceeding 1 gram are not established, safety at these higher doses remains uncertain. No specific timing recommendations exist, but cognitive function benefits may be observable shortly after intake. Common forms include freeze-dried powders and extracts, which exhibit improved bioavailability when consumed with fats.
