Supplement Panel Images: Distinguish an Image Caption from a Complete Accessible Transcription
Check whether text accompanying a label image actually contains the panel information needed for the buying question.
We have not performed hands-on testing of the products discussed. Manufacturer references and official guidance support the documented information below; comparison exercises are our editorial guidance.
A shopping page may announce an image as bottle right or Supplement Facts without making the panel’s words available as readable text. That caption can help identify the image, yet it is not a complete label record. This guide explains how to request and compare accessible information without guessing ingredients from a short image description or relying on an unverified automatic transcription.
Identify what the accompanying text actually provides
The consulted NOW glycine page provides bottle-image descriptions and a separate text facts panel with ingredient and serving information. Those are different information layers. A short caption naming a bottle side helps locate an image; the actual panel transcription supplies the details. Keep the image reference and the text source together when compiling a comparison, rather than treating either short caption as the whole formula.
Use the image’s purpose to define the missing information
W3C’s informative-image guidance explains that alternatives should convey the relevant information or function of an image. For a buyer asking about a particular panel entry, useful information includes that entry’s full name, qualifier, amount, unit and associated serving line. A generic label-photo caption does not supply those details. Ask for an accessible complete label or a written manufacturer response tied to the exact product.
Worked example: handle a screen-reader information gap
Imagine an illustrative shopper’s reading tool announces Supplement Facts image and then jumps to reviews. Mark the ingredient-panel fields unavailable rather than copying the product headline into them. Check whether the manufacturer supplies a separate complete text panel, and save its exact product reference. If a third-party transcription is used to locate the issue, retain it as provisional until checked against authoritative product information; do not silently correct uncertain units or missing qualifier words.
Keep accessibility and formula currency connected
A readable text version still needs to match the exact offered variant and current package. Preserve the source date, full product name and any unresolved mismatch between image and text. Do not assume an accessible panel for one capsule strength also describes another strength, powder or regional item. This guide does not claim that every page or reading tool was tested; it provides a method for identifying what information is available and requesting what is missing. Its goal is a reviewable product record that can be read in the needed format. If the seller cannot provide that record, the composition comparison remains incomplete even when the front image is clear and the product title seems familiar.
Compare the trade-offs
| Option | Useful when | Purchase limitation |
|---|---|---|
| Image caption | Identify the depicted side or panel | A short caption need not contain the panel’s data |
| Separate text panel | Match exact product and source date | Readable information can still belong to another variant |
| Unverified transcription | Flag uncertain units and qualifiers | Do not convert a provisional reading into a verified label |
Your purchase checklist
- Distinguish locating an image from reading its full content.
