Heart Disease and Metabolic Syndrome
To determine whether or not bilberry can prevent heart disease, there is insufficient scientific evidence. It may lower cholesterol [5] levels and inflammatory indicators including C-reactive protein (CRP) [6], according to a few modest studies.28 According to other studies, bilberry had no effect on blood pressure, cholesterol, or weight.
Bilberry extract supplementation and/or ingestion of fresh bilberries may lower cholesterol, blood sugar, and insulin levels, according to a review of studies published in 2020. Bilberries may help persons with metabolic syndrome lower inflammation, the study’s authors added.
Although much of this research was conducted in laboratories or on animals, the authors emphasized that they may not apply to humans and that much larger investigations are required before bilberry may be advised for treating any conditions.
