Mirtoselect European Bilberry Extract
Also known as: European Bilberry Extract, Vaccinium myrtillus L. Extract, Mirtoselect, Bilberry Extract, Mirtoselect European Bilberry Extract
Overview
Bilberry extract is derived from the fruits of *Vaccinium myrtillus L.*, a standardized dry extract recognized by the European Pharmacopoeia, which contains 32.4% to 39.6% anthocyanins. Rich in anthocyanins, these polyphenolic compounds have been shown to promote various health benefits, particularly in ocular and cardiovascular health. The unique composition of bilberry includes five anthocyanidins and three sugars, making it a powerful source of antioxidants. Research on bilberry extract suggests moderate maturity in understanding its health benefits, though there is an ongoing need for more extensive systematic reviews. It is typically used for enhancing visual function, supporting cardiovascular health, and providing antioxidant support, establishing it as a useful dietary supplement.
Benefits
Several evidence-backed benefits of bilberry extract include significant improvements in eye health, notably in tear secretion for those with dry eye symptoms (p = 0.019). The extract significantly boosts antioxidant capacity, as demonstrated by an increase in plasmatic antioxidant potential (p = 0.003). Cardiovascular benefits were observed, with reductions in blood pressure reported (systolic: 4.7 mmHg, diastolic: 2.3 mmHg, p < 0.001). Preliminary findings suggest protective effects against liver conditions and potential anti-cancer properties; however, these are primarily based on animal research. Individuals suffering from dry eye symptoms and those at risk for type 2 diabetes may derive the most benefit from bilberry supplementation.
How it works
The efficacy of bilberry extract stems from its high anthocyanin content, which displays antioxidant and anti-inflammatory properties. These anthocyanins interact with pro-inflammatory genes to mitigate oxidative stress and may influence gut microbiota, impacting pathways related to ocular, cardiovascular, and liver functions. Moreover, the presence of non-anthocyanin components in formulations like Mirtoselect enhances the absorption and bioavailability of these active compounds within the body.
Side effects
Bilberry extract is generally considered safe, although comprehensive long-term safety data is lacking. Studies have not documented common side effects occurring in more than 5% of users, and rare adverse effects remain unspecified. There are no recognized unusual effects (1-5%). Caution is advisable for individuals on anticoagulant medications, as bilberry may have antiplatelet effects. While no specific contraindications have been highlighted, individuals with sensitivities to berries or those preparing for surgery should consult healthcare providers. Pregnant or breastfeeding women are recommended to seek medical advice before usage due to insufficient safety data.
Dosage
The recommended dosage for bilberry extract is generally between 250-300 mg daily, ensuring it contains at least 36% anthocyanins for optimal efficacy. While the minimum effective dose is not distinctly defined, this dosage range has been successfully utilized in various studies. No established maximum safe dosage exists, with doses up to 300 mg per day reporting no significant adverse effects. It is advisable to consume bilberry extract with meals to enhance absorption. Mirtoselect, which is noted for its higher bioavailability, is the preferred formulation for supplementation.
