BILBERRY EXTRACT 4:1 (FRUIT)

Bilberry (Vaccinium myrtillus) extract is derived from the dark blue fruit of a low-growing shrub native to Northern Europe. This particular extract, specified as 4:1, indicates that four parts of the raw bilberry fruit are concentrated into one part of the extract, signifying a potent concentration of its beneficial compounds. Historically, bilberry has been valued in traditional European medicine for centuries, particularly for its perceived benefits related to vision and circulation. The fruit is rich in a diverse array of phytonutrients, with its deep color signaling the presence of anthocyanins, a class of flavonoids responsible for much of its therapeutic potential. These water-soluble pigments are not only powerful antioxidants but also contribute significantly to the extract's overall bioactivity, making it a highly sought-after ingredient in the nutraceutical industry for its distinct profile and traditional efficacy. The careful extraction process ensures the preservation and concentration of these delicate compounds, providing a standardized product for various health applications.

The primary health benefits of bilberry extract are largely attributed to its rich anthocyanin content, which includes compounds like delphinidin, cyanidin, petunidin, malvidin, and peonidin glycosides. These potent antioxidants work by neutralizing free radicals, thereby reducing oxidative stress throughout the body. Research indicates that bilberry anthocyanins can cross the blood-retinal barrier, where they contribute to ocular health by enhancing microcirculation, strengthening capillary walls, and promoting rhodopsin regeneration – a critical process for low-light vision. A study published in the Journal of Agricultural and Food Chemistry highlighted the significant antioxidant capacity of bilberry anthocyanins. Beyond ocular support, these compounds also exhibit anti-inflammatory properties, modulating various inflammatory pathways. Furthermore, bilberry extract has been investigated for its potential cardiovascular benefits, including supporting vascular integrity and healthy blood flow, primarily through its ability to influence nitric oxide production and reduce endothelial dysfunction. The complex synergy of these bioactive compounds provides a multi-faceted approach to supporting overall physiological well-being.

Bilberry extract 4:1 finds extensive application in dietary supplements targeting eye health, cardiovascular support, and antioxidant formulations. It is commonly incorporated into capsules, tablets, and powders, often alongside complementary ingredients such as lutein, zeaxanthin, omega-3 fatty acids, and vitamin C, to create synergistic effects. When selecting bilberry extract, quality considerations are paramount, including standardization to a specific anthocyanin content, often ranging from 25% to 36%, to ensure consistent potency and efficacy. Traceability of the raw material, absence of contaminants, and adherence to Good Manufacturing Practices (GMP) are crucial for premium products. Clinical trials have demonstrated the efficacy of bilberry extract in improving visual acuity and reducing eye fatigue, particularly in individuals exposed to prolonged screen time. For instance, a review in Fitoterapia underscored bilberry's role in improving night vision and reducing visual discomfort. Its traditional use, coupled with modern scientific validation, solidifies its position as a valuable ingredient for health-conscious consumers seeking natural support for vision and overall antioxidant defense.
