Mirtoselect Bilberrry Extract

Also known as: Vaccinium myrtillus L., Bilberry, European Blueberry, Mirtoselect, Mirtoselect Bilberry Extract

Overview

Bilberry extract, derived from the fruit of *Vaccinium myrtillus L.*, is a potent dietary supplement characterized by its high anthocyanin content, approximately 36% in the standardized extract Mirtoselect®. This extract is known for its strong antioxidant properties and is particularly similar to blueberries and cranberries. Bilberry extract has garnered attention for its potential health benefits, including promoting eye health, improving cardiovascular function, and exerting antioxidant effects. Research supporting these claims includes systematic reviews and randomized controlled trials, which, despite some limitations like small sample sizes, generally affirm its efficacy. Regular supplementation is typically aimed at enhancing ocular function and supporting cardiometabolic health.

Benefits

Bilberry extract offers several evidence-backed benefits, particularly for eye health. It has been shown to significantly improve tear secretion in individuals suffering from dry eye syndrome, as indicated by enhanced Schirmer’s test scores (p = 0.019). Moreover, it promotes retinal health through increased blood flow velocity. Additionally, bilberry extract has been associated with a reduction in blood pressure, averaging a decrease of 4.7 mmHg systolic and 2.3 mmHg diastolic in at-risk individuals. The antioxidant properties highlight its cardiometabolic benefits, with stronger evidence seen in populations experiencing dry eye symptoms or retinal disorders. The extract’s effectiveness appears clinically significant with moderate effect sizes, especially when used for durations of 4 weeks to 6 months.

How it works

The beneficial effects of bilberry extract are largely attributed to its high anthocyanin content, which serves as a potent antioxidant, aiding in the reduction of oxidative stress and enhancing vascular health. Thus, it can alleviate dry eye symptoms through improved tear secretion, while also promoting cardiovascular wellness by enhancing blood flow and aiding in blood pressure regulation via anti-inflammatory and antioxidant pathways.

Side effects

Bilberry extract is considered generally safe, with no significant side effects commonly reported in clinical studies. While detailed common and rare side effects are not tracked, caution is advised for individuals taking anticoagulant medications due to potential effects on blood clotting. Although no specific contraindications are noted, it is recommended that individuals with underlying health issues or those on particular medications consult a healthcare provider before starting bilberry extract. Pregnant or breastfeeding women should also seek professional guidance to ensure the extract's safety.

Dosage

The typical recommended dosage of Mirtoselect® bilberry extract ranges from 250 mg to 500 mg per day, standardized to about 36% anthocyanins. While a definitive minimum effective dose is not established, existing research supports this dosage range for efficacy. There are no established upper limits, with doses up to 500 mg daily reported without adverse effects. For optimal absorption, it is advisable to take the extract with meals. It is commonly available in capsule and tablet forms, with enhanced absorption observed in the presence of non-anthocyanin compounds included in the extract.
