Photograph the Supplement Facts panel
The white box with the ingredient list, not the front of the bottle. Drop a photo or tap to upload, then crop to the panel.
Point your camera at the barcode on the bottle
Or type the barcode number
The crop is uploaded for cloud OCR and then discarded; it is not stored. If the cloud service is unreachable, reading falls back to this device.
Crop
Frame the Supplement Facts panel
Drag the corners so the white ingredient box fills the frame. Extra bottle art makes OCR worse.

Step 2 of 3
Does this match the label?
OCR misreads numbers. Check each line against the photo, then set how many servings you actually take.
Daily intake
Servings you take per day
The panel lists amounts per serving. If you take two scoops, set this to 2.
Step 3 of 3
How the doses compare
Each line against published trial data in the Clinical Dose Registry. This is not a product ranking.
How to use this
- Photograph the Supplement Facts panel — the white box with the ingredient list, not the front of the bottle.
- Barcode scanner tab: photograph the barcode instead of the panel. We match it to the NIH Dietary Supplement Label Database and prefill the record; you still confirm every line against your bottle.
- Crop to that box: drag the corners so OCR sees the panel, not the rest of the bottle.
- Confirm what we read: check each name and dose, drop lines that are not actives, then compare.
- Set servings per day: the label shows per-serving amounts. If you take 2 capsules twice daily, that is 2 servings per day.
- Read the evidence comparison: lines with a studied dose in our registry get a status, from Matched to Evidence form mismatch; the rest of the label is listed without a verdict. Percent is of the lowest studied dose, not a safety score.

Frequently asked questions
Does this rank brands or products?
No. The scanner compares each confirmed ingredient dose to published trial floors in the Clinical Dose Registry. It does not score bottles, brands, or “best of” lists.
What does the percentage mean?
Percent is your daily intake divided by the lowest studied dose for that ingredient in our registry. It is not a safety score, not a Daily Value, and not a product grade.
Why do some label lines get no verdict?
Only ingredients with a studied dose floor in the Clinical Dose Registry get Matched, Below, Above, or Evidence form mismatch. Everything else stays on the label list without a comparison.
Label photo vs barcode: what is the difference?
Label scanner reads the Supplement Facts panel with OCR. Barcode scanner looks up the NIH Dietary Supplement Label Database record for that code and prefills the lines; you still confirm every amount against your bottle.
Does my photo leave this device?
The crop is uploaded for cloud OCR and then discarded; it is not stored. If the cloud service is unreachable, reading falls back to this device. Barcode lookup downloads one NIH DSLD shard and may fetch an Open Food Facts bottle photo; nothing else leaves the browser.
What about proprietary blends?
If individual amounts inside a blend are undisclosed, the scanner cannot compare those actives to trial floors. Use the proprietary blend floor check when you only have a total blend weight.
