High-Anthocyanin natural ingredient – derived from high-quality wild and cultivated blueberries (Vaccinium corymbosum). Rich in anthocyanins, flavonoids, and essential polyphenols, this extract serves as a powerful functional ingredient for the global food, beverage, and dietary supplement industries. At Nutralighting, we are committed to delivering consistent, high-purity blueberry extract powder that meets the stringent requirements of B2B buyers across international markets.

Product Description

In the eye care and antioxidant categories, formulators often face the challenge of unstable active ingredient content and large batch-to-batch differences. Blueberry provides standardized anthocyanins (25%-36%) to ensure predictable content and stable supply, helping you turn ‘eye care ingredients’ from a concept into a scalable formula.

Its anthocyanin components (mainly cyanidin-3-glucoside) have shown antioxidant and microcirculation support activity in in vitro studies, making it a stable plant ingredient for eye care, antioxidant, and microcirculation support formulations.

Blueberry is a wild berry primarily produced in North America, with anthocyanin content relatively high among Vaccinium species. The global market demand for plant ingredients in eye care and antioxidant products continues to grow, with North America and Europe as major consumer markets.

Basic Information

Standard Specifications (COA)

The following specifications are general reference values and are subject to the COA report of each batch.

Plant Material Introduction

The raw material of this product is the dried mature fruit of Vaccinium corymbosum, a species of the Ericaceae family. A perennial berry-bearing shrub, its fruits are deep blue or violet in colour and covered with a white bloom; it is renowned for being rich in anthocyanins and vitamin C, and is hailed as the ‘king of berries’.

Core Efficacy

The following summary of effects is based on published scientific research and traditional applications; specific efficacy should be evaluated in combination with product dosage forms and usage amounts.

Blueberry (Vaccinium corymbosum) extract has been extensively studied for vision protection and microcirculation support, with its anthocyanin content higher than that of commonly cultivated blueberries (cyanidin-3-glucoside content approximately 4%-8%). Studies show that lowbush blueberry anthocyanins can inhibit aldose reductase (IC50 = 3.8 μM), reduce sorbitol accumulation in the retina, and promote NO production by upregulating eNOS expression, which helps maintain retinal microcirculation. Relevant human studies suggest that regular supplementation with lowbush blueberry extract may support night vision sensitivity and dark adaptation. Its anthocyanins also possess anti-inflammatory and antioxidant activities and can reduce oxidative stress damage by activating the Nrf2/HO-1 pathway. The above results are mainly based on in vitro and animal experiments, and specific applications need to be further evaluated in combination with dosage forms and doses.
