Bilberry
A European blueberry relative carrying a persistent WWII pilot myth. The night-vision claim is false; the eye evidence that does exist is about something else.
How Bilberry actually works
Anthocyanins that strengthen capillary basement membrane by stabilising collagen cross-links, and improve retinal microcirculation specifically. They also have direct antioxidant activity in retinal tissue and appear to support rhodopsin regeneration.
Bilberry quick facts
| Suggested dose | 160–320 mg daily standardised to 25–36% anthocyanosides. |
| How often | Daily |
| Who it's for | Screen-related eye fatigue. Not night vision. |
✅ Clinically validated
- Multiple trials of the night-vision claim in healthy people have been NEGATIVE. This is settled and the myth persists anyway.
- Trials report reduced eye fatigue and improved accommodation with screen use — small but replicated across several Japanese studies.
- Trials in diabetic retinopathy and glaucoma show improvements in retinal microcirculation. Small and preliminary.
📊 Correlative data
- The RAF night-vision story from the Second World War is the famous claim and **it appears to be wartime myth rather than observation** — controlled testing has not reproduced it. Genuine European traditional use for vascular and eye complaints does predate that story.
🧪 Theoretical / extrapolated benefits
- Anthocyanins support capillary integrity and regeneration of rhodopsin — the mechanism the pilot story was built on, which did not survive testing.
These tiers tell you how much human evidence exists — not how well something works. This is the research space, and most of what’s in here is new rather than disproven. Something sitting at “theoretical” usually means nobody has funded the trial, not that the trial was run and failed.
The trap runs the other way too: something can be clinically validated and still do very little for you specifically. A statistically significant result in a study population is not a promise about your body.
- ✅ Clinically validated — human randomised trials or meta-analyses support it. The strongest footing available.
- 📊 Correlative — observational or epidemiological data. Suggestive, and genuinely useful for direction, but it cannot establish cause.
- 🧪 Theoretical / mechanistic — the mechanism is understood and often demonstrated in cells or animals, and the human trial doesn’t exist yet. Unproven is not the same as ineffective. Plenty of what’s standard practice today sat here five years ago.
✗ is a safety flag, not a grade. Where you see it, the concern is harm — not a disappointing trial. A compound tested for one purpose and found not to help there can still be worth studying somewhere else, so a negative result never gets rendered as a cross. It sits alongside the tier, because something can be both well-studied and genuinely risky.
My job is to tell you which one you’re looking at, and let you make the call. Grading something low isn’t me dismissing it — it’s me refusing to oversell it. This is the research space, and being able to reason forward from a mechanism matters as much as waiting for the trial.
The famous RAF-night-vision story from the Second World War is a myth and has been tested and refuted. The capillary and retinal microcirculation evidence is not — trials support benefit in diabetic retinopathy and venous insufficiency. Worth separating those two things, since the myth has done the ingredient's reputation more harm than good among people who checked.
Bilberry — safety & side effects
- Well tolerated; GI upset at higher doses.
- Antiplatelet activity — Additive bleeding risk with anticoagulants and antiplatelets — warfarin, apixaban, rivaroxaban, clopidogrel, and aspirin at any dose. The interaction is pharmacodynamic rather than metabolic, so it does not show up as a changed drug level; it shows up as bruising, nosebleeds or a raised INR. Stop at least two weeks before any surgery or dental extraction. Surgeons ask about prescription blood thinners and rarely about supplements, so this one is on you to volunteer.
- Lowers blood glucose modestly. Additive with diabetes medication.
Not medical advice. If you take prescription medication or have a diagnosed condition, check this against it with a pharmacist or doctor — pharmacists are underused and free.
