Bilberry Organic — Eye Health & Circulation Support*
LifeSource Vitamins Bilberry Organic provides anthocyanin-rich European bilberry (Vaccinium myrtillus) to support eye health, comfortable visual performance, and healthy microcirculation.* Produced in GMP facilities and 3rd-party lab tested for identity, potency, and purity.*
Research Promise: At LifeSource Vitamins, our commitment is rooted in research and results. Every benefit below is supported by human clinical studies indexed in the National Institutes of Health (NIH) via PubMed, with full texts available in the National Library of Medicine (NLM) PubMed Central (PMC) when available. In addition, we reference reviews from 39 leading health organizations and insights from 20 top global universities to ensure our guidance aligns with credible science.*
Clinically Studied Benefits (with research)
