A dark European berry with a reputation for night vision.
Retina ClearIn plain words
Bilberry is a wild cousin of the blueberry. Its extract is measured by its anthocyanin content, the purple pigments that act as antioxidants.
Retina ClearWhat the evidence shows
The night-pilot story is a wartime legend. A 2004 systematic review of placebo-controlled trials found that the stronger studies showed no real night-vision gain. Later work on eye fatigue is small and mixed.
In this capsule
The seller lists bilberry fruit extract without saying how strong the extract is or how much is used.
Watch-outs: Generally fine. Some berry extracts may add to blood thinners, so mention it to a pharmacist.
Common question
Will bilberry help me see in the dark?
Not according to the best trials. Treat it as an antioxidant berry.
