Bilberry Extract
Also known as: bilberry, European blueberry, wild blueberry, bleuet, vaccinium myrtillus extract, Vaccinium myrtillus
Overview
Bilberry extract is derived from the fruit of Vaccinium myrtillus, recognized for its vibrant blue color attributed to high concentrations of anthocyanins, potent antioxidant compounds. Traditionally utilized for various health benefits, such as cardiovascular health, vision enhancement, management of Type 2 diabetes, and gastrointestinal health, the evidence supporting these claims is varied. While some studies suggest beneficial effects, many findings remain inconclusive, highlighting the need for more systematic research. Bilberry is typically consumed in extract form, standardized for anthocyanin content, and is widely available in capsules and powders. Ongoing research aims to establish clearer efficacy and applications in health outcomes.
Benefits
Bilberry extract may offer potential benefits in several domains: 1. **Cardiovascular Health**: Some studies indicate that bilberry may assist in lowering blood pressure, especially when used in conjunction with grape seed extract, although this evidence arises from studies with limited participant numbers. 2. **Ulcerative Colitis**: Preliminary findings from a pilot study show bilberry may have therapeutic effects for individuals with mild to moderate ulcerative colitis, indicating improvements in gastrointestinal health. 3. **Vision Disorders**: Although bilberry is traditionally credited with enhancing night vision, scientific backing is mainly anecdotal, with current literature indicating insufficient evidence. 4. **Type 2 Diabetes**: There are some indications of bilberry leaves being helpful for glycemic control; however, the evidence for the fruit extract remains unclear. Overall, due to inconsistencies and limitations in current studies, more rigorous research is essential to validate these benefits.
How it works
The health benefits of bilberry extract are closely linked to its rich anthocyanin content, which exhibits robust antioxidant properties. These compounds are thought to enhance endothelial function and improve blood circulation while helping to reduce inflammation. Specifically, anthocyanins may modulate nitric oxide synthesis, which contributes to better vascular health. Additionally, bilberry has been suggested to influence glycemic levels and gut health, although the exact biological mechanisms involved require further clarification.
Side effects
Bilberry extract is generally safe for the majority of individuals when taken as directed. However, some may experience minor side effects such as gastrointestinal discomfort, diarrhea, or allergic reactions. Serious adverse effects are uncommon, but caution is recommended for individuals on anticoagulant medications, as bilberry may potentiate their effects due to blood-thinning properties. Individuals with known allergies to bilberry or related plants should abstain from use. Long-term consumption of high doses might lead to more severe complications, thus it is advisable to consult a healthcare provider before beginning supplementation, especially for those with underlying conditions or those who are pregnant or breastfeeding.
Dosage
The most commonly recommended dosage of bilberry extract typically ranges from 160 mg to 480 mg per day, often divided into two or three separate doses depending on the intended health benefit. For optimal absorption, it is advisable to ingest bilberry extract with meals. Specific conditions may necessitate different dosages, highlighting the importance of adhering to product instructions or seeking personalized advice from a healthcare provider. The safety thresholds for prolonged use have not been thoroughly defined, thus users should monitor their symptoms and consult healthcare professionals for evaluations and potential dosage adjustments.
