With the growing recognition of bilberry extract's diverse health benefits, from supporting vision to acting as a potent antioxidant, understanding how to choose a quality product is essential. Not all bilberry extracts are created equal, and the efficacy of a supplement often hinges on its standardization, purity, and the reputation of the manufacturer.

The most critical factor when selecting bilberry extract is its standardization. Bilberries are prized for their anthocyanin content, the compounds responsible for many of their health-promoting properties. Look for products that clearly state the concentration of anthocyanins, typically standardized to a minimum of 25%. This ensures that you are receiving a consistent and potent dose of the active ingredients. Extracts that are not standardized may have widely varying levels of anthocyanins, making their effectiveness unpredictable.

Purity is another paramount consideration. High-quality bilberry extracts should be free from unnecessary fillers, artificial additives, or contaminants. Reputable suppliers will often provide Certificates of Analysis (CoA) that detail the product's composition and confirm its purity. This is particularly important given concerns about adulteration in some botanical extracts, where cheaper ingredients might be used to mimic the appearance or purported effects of genuine bilberry extract.

The source and processing of the bilberries also play a role. Bilberries (Vaccinium myrtillus) are native to Northern Europe and are distinct from North American blueberries, often possessing a higher concentration of anthocyanins. The method used to extract these beneficial compounds can also affect their potency and bioavailability. Reputable manufacturers invest in advanced extraction technologies to preserve the integrity of these delicate compounds.

When you buy bilberry extract, choose a supplier with a strong track record and positive customer reviews.
