BILBERRY EXTRACT 1.5%

Bilberry Extract 1.5% is a highly valued botanical ingredient derived from the fruit of Vaccinium myrtillus, commonly known as European blueberry. Native to northern Europe, this small, dark berry has been traditionally utilized for centuries, particularly for its perceived benefits related to vision and circulatory health. The extract is meticulously processed to concentrate its beneficial compounds, with a key focus on standardization to ensure consistent potency. This specific extract is standardized to contain 1.5% anthocyanosides, a class of potent polyphenolic pigments responsible for bilberry's deep purple color and many of its therapeutic properties. The careful extraction process preserves the integrity of these delicate compounds, making it a reliable and efficacious raw material for dietary supplement formulations. This standardization is crucial for ensuring product quality and predictable biological activity, distinguishing it from non-standardized forms of the berry.

The primary active compounds in Bilberry Extract are anthocyanosides, a subgroup of flavonoids. These include various anthocyanins such as delphinidin, cyanidin, petunidin, malvidin, and peonidin, present as glycosides. These compounds exert their health benefits primarily through powerful antioxidant and anti-inflammatory mechanisms. Research indicates that anthocyanosides can scavenge free radicals, thereby reducing oxidative stress that contributes to cellular damage, particularly in delicate tissues like the retina. Furthermore, they are believed to support vascular integrity by strengthening capillary walls and improving microcirculation. This effect is particularly relevant for eye health, where improved blood flow can enhance nutrient delivery and waste removal from ocular tissues. Studies have also suggested their role in rhodopsin regeneration, a critical process for adapting to low-light conditions and maintaining night vision.

Bilberry Extract 1.5% finds extensive application in dietary supplements aimed at supporting eye health, cardiovascular function, and general antioxidant protection. It is commonly incorporated into capsule, tablet, and powder formulations, and can also be found in functional beverages. When formulating with bilberry, considerations for quality extend beyond standardization to include the purity of the raw material, the absence of contaminants like heavy metals and pesticides, and proper storage to maintain stability of anthocyanosides. Clinical studies have explored bilberry's efficacy, with some research indicating improvements in visual fatigue and night vision adaptation among individuals consuming bilberry extracts. For instance, a review of studies highlighted its potential in supporting retinal health. It is often synergistically combined with other vision-supportive nutrients like lutein, zeaxanthin, and Vitamin C to enhance its overall efficacy in comprehensive eye health formulas.
