European Bilberry Extract
European Bilberry Extract: Benefits and Mechanisms
European Bilberry Extract is derived from the fruit of the European bilberry (Vaccinium myrtillus). This extract is rich in anthocyanins, a type of flavonoid with powerful antioxidant properties. European bilberry extract has been used traditionally for various health benefits, particularly for eye health, cardiovascular health, and anti-inflammatory effects.
Key Components of European Bilberry Extract
Anthocyanins: These are the primary active compounds in bilberry extract, responsible for its vibrant blue-purple color. Anthocyanins are potent antioxidants that protect cells from oxidative damage, improve microcirculation, and support overall cardiovascular and eye health.
Flavonoids: In addition to anthocyanins, bilberry extract contains various other flavonoids that contribute to its antioxidant and anti-inflammatory properties.
Anthocyanidins 25% (UV)/ Anthocyanoins 36% (HPLC)
Anthocyanidins 18% (UV)/ Anthocyanoins 25% (HPLC)
Eye Health Support
Mechanism: European Bilberry Extract enhances vision and eye health by improving microcirculation and reducing oxidative stress in ocular tissues. Anthocyanins in bilberries support the regeneration of rhodopsin, a visual pigment crucial for low-light and night vision.
Supporting Evidence: A study published in "Investigative Ophthalmology & Visual Science" (2011) demonstrated that anthocyanins from bilberry extract improved night vision and reduced eye fatigue in healthy subjects (Matsumoto et al., 2011). Another study in "Journal of Agricultural and Food Chemistry" (2005) indicated that bilberry extract protected retinal cells from oxidative damage (Ohguro et al., 2005).
Cardiovascular Health
Mechanism: The anthocyanins in European Bilberry Extract exert cardioprotective effects by enhancing endothelial function, reducing blood pressure, and inhibiting platelet aggregation. They also reduce oxidative stress and inflammation, which are key factors in cardiovascular diseases.
Supporting Evidence: Research in "The American Journal of Clinical Nutrition" (2010) found that bilberry extract improved vascular function and reduced arterial stiffness in patients with cardiovascular risk factors (Karlsen et al., 2010). Another study in "Atherosclerosis" (2007) showed that bilberry extract supplementation reduced blood pressure and improved lipid profiles in hypertensive patients (Meyers et al., 2007).
Anti-inflammatory Effects
Mechanism: Anthocyanins in European Bilberry Extract inhibit the NF-κB pathway, reducing the production of pro-inflammatory cytokines and enzymes. This helps in managing chronic inflammatory conditions and reducing inflammation-related tissue damage.
Supporting Evidence: A study in "Free Radical Biology and Medicine" (2008) demonstrated that bilberry extract significantly reduced markers of inflammation in animal models of inflammatory diseases (Kolehmainen et al., 2008). Another study in "Journal of Nutritional Biochemistry" (2013) indicated that anthocyanins from bilberry extract had potent anti-inflammatory effects in human cell cultures (Zafra-Stone et al., 2013).
Conclusion
European Bilberry Extract is a valuable natural supplement with a wide range of health benefits supported by scientific research. Its ability to support eye health, improve cardiovascular function, and reduce inflammation makes it an excellent choice for promoting overall health and well-being. Rich in anthocyanins and flavonoids, European Bilberry Extract is a well-researched and effective option for enhancing health.
