Bilberry Fruit Extract Blend
Also known as: Vaccinium myrtillus, Bilberry, European Blueberry
Overview
Bilberry fruit extract is derived from *Vaccinium myrtillus*, a plant abundant in anthocyanins and other phenolic compounds. It's traditionally used for potential health benefits, including supporting eye health, cardiovascular function, and diabetes management. However, the evidence supporting these uses varies in quality, with some studies lacking rigorous methodology or sufficient sample sizes. Research on bilberry is ongoing, exploring its effects on metabolic syndrome and inflammation. The extract is available in various forms, including capsules, tablets, and powders, and is sourced directly from the bilberry fruit. While generally considered safe, it's essential to source bilberry supplements from reputable manufacturers to ensure quality and purity.
Benefits
Bilberry extracts may offer benefits in reducing dyslipidemia and chronic inflammation, although the evidence is not consistently strong. A meta-analysis suggests that dietary anthocyanin consumption, including from bilberries, may reduce the risk of type 2 diabetes by approximately 15%. Some evidence supports anti-obesity, anticarcinogenic, cardioprotective, and antimicrobial effects, but further validation is needed. The benefits are generally not specific to any population, though some studies suggest potential benefits for individuals with metabolic syndrome. The strength of evidence varies, with some benefits supported by meta-analyses and others requiring more rigorous research.
How it works
Bilberry extracts primarily exert their effects through their antioxidant properties, mainly due to anthocyanins. These compounds can interact with various biological pathways to exert anti-inflammatory and potentially hypoglycemic effects. Anthocyanins scavenge free radicals, reducing oxidative stress and inflammation. The absorption and bioavailability of these compounds can vary based on the extract formulation and individual metabolism, influencing the extent of their biological activity.
Side effects
Bilberry fruit is generally considered safe when consumed in typical food amounts. Extracts have been used safely in research up to 160 mg/day for several months. Common side effects are not consistently reported, but potential gastrointestinal upset is possible. Rare side effects are not well-documented. Bilberry may interact with anticoagulants due to potential antiplatelet effects, so caution is advised for individuals taking blood-thinning medications. High doses of bilberry leaves may be unsafe, and caution is advised during pregnancy or breastfeeding. Consult a healthcare provider before use, especially if you have underlying health conditions or are taking medications.
Dosage
The minimum effective dose of bilberry extract is not well-established. The typical dosage range for fruit extracts is 160 mg/day or less. The maximum safe dose is not clearly defined. There are no specific timing recommendations for bilberry consumption. Aqueous, methanolic, and hydro-methanolic extracts have been studied, with varying bioactivities. Due to the lack of strict regulation of supplements, it is important to choose products from reputable sources to ensure quality and accurate dosing. Always follow the manufacturer's instructions or consult with a healthcare professional for personalized advice.
