Bilberry for Anti-Inflammatory

Research suggests that bilberry possesses meaningful anti-inflammatory properties, with evidence drawn from in vitro cell studies, animal models, and a smaller body of human clinical trials generally supporting its ability to reduce key inflammatory markers such as TNF-α, IL-6, IL-1β, and NF-κB signaling activity. A 2022 review compiling cell, animal, and human data found that bilberry supplementation in various forms lowered inflammatory markers in most trials involving people with metabolic disorders, and multiple preclinical studies corroborate these findings across different models of inflammation, including liver injury, retinal damage, and cellular aging. However, the evidence is not uniformly positive — one 2014 cell study found that bilberry anthocyanins had opposing effects depending on which inflammatory pathway was activated, enhancing NF-κB signaling in some contexts while suppressing it in others, suggesting the effects are pathway-specific rather than broadly anti-inflammatory. Most researchers in this area conclude that while the overall direction of evidence is promising, large-scale randomized controlled trials are still needed to establish the magnitude of benefit, optimal sources and forms of supplementation, and effects across different health conditions and populations.
