What it checks

The numbers a label doesn't show you

The same checks run on every product, whoever makes it.

Real price, per serve

Price per serve, per day and per gram, and per 100 mg of the actual ingredient, so a 500 mg tablet and a 200 mg capsule can be compared fairly. Prices from NZ, US and UK shops are converted to A$.

Ingredient form and elemental amount

Spots weaker forms such as magnesium oxide or zinc oxide, and works out how much actual magnesium, zinc, iron or calcium a compound weight really gives you.

Upper-level warnings

Warns when one serve is over the adult upper level, using the lower of the Australian (NHMRC) and US (NIH) figures, with the source one click away.

Hidden doses and blends

Flags proprietary blends, omega-3 with no EPA/DHA amount, probiotics with no strain IDs, and herbal extracts that don't say how strong they are.

Built for Australia and NZ

Understands TGA-style labels (amounts per capsule, "equiv. to", micrograms) and finds AUST L and AUST R numbers so you can look them up on the TGA register.

Reads label pictures too

If a shop shows the label as an image, one click on Scan screen reads it on your device. The picture is never uploaded.

Install guide

Up and running in under a minute

It installs like any other Chrome extension and updates itself.

  1. Open the Chrome Web Store listing

    The Chrome Web Store listing is coming soon. This page will link to it the moment it's live. Use Chrome on a computer (Windows, Mac, Linux or ChromeOS). Edge and Brave also work.

  2. Click Add to Chrome

    Press Add to Chrome, then Add extension in the pop-up. It asks for only two small permissions, explained on the data and permissions page.

  3. Pin it so it's always one click away

    Click the puzzle-piece 🧩 in Chrome's toolbar, then the pin next to Supplement Checker. The green capsule icon now sits beside your address bar.

  4. Open any supplement product page and click the icon

    Go to a product on any supplement shop and click the capsule. It reads the page you're on and shows the price per serve, ingredient flags and an ingredient picker in the Calculator tab, in about a second.

  5. Label is a picture? Scan it

    Scroll the label into view, open the extension and press Scan screen. You can also upload an image or paste a screenshot. It works best on clear, flat labels and is not great with curved bottles or non-English labels.

Not on a computer? Chrome on phones and tablets doesn't support extensions, so Supplement Checker is desktop only. To remove it later, right-click the icon and choose Remove from Chrome.
Private by design

It collects nothing.

No accounts, no tracking, no ads. Everything is worked out inside your browser.

Data and permissions
  • Reads only the tab you open it on, and only when you click the icon.
  • Nothing leaves your computer. No page text, screenshots or images are sent anywhere or stored.
  • Label scanning runs on your device with software bundled inside the extension.
  • Two small permissions only, and no access to all your websites.
Good to know

A tool to compare, not to diagnose

Supplement Checker gives general information, not medical advice. It reads text from the page (or a label image), so it can misread, and some shops only show labels as pictures. Always check the label itself, and ask a health professional about what suits you.

Questions

FAQ

Is it really free?

Yes. There's no paid version, no account and no ads.

Who makes it, and does it favour ShilNepal?

It's made by ShilNepal, an Australian shilajit retailer. The checks are the same for every product, including ShilNepal's. On shilajit pages the extension shows one clearly labelled "From ShilNepal" card so the connection is out in the open.

Which shops does it work on?

Any shop that shows the ingredients as text on the page. It has been tried on pharmacies, brand stores and marketplaces. Where a shop only shows the label as a picture, use Scan screen. Search and category pages show many products at once, so open a single product page.

It got something wrong. What should I do?

Tell us at info@shilnepal.com with the link to the product page. Real examples are how the checks get better.

Does it work on my phone?

No. Browser extensions need desktop Chrome, Edge or Brave.

What does it do with my data?

Nothing is collected, stored or sent. The full detail, including each permission and why it's needed, is on the data and permissions page.
