Tools for checking supplement labels and evidence

Compare a price, keep a source record or help your readers find a brand’s evidence profile. Start with the task you need to do.

Choose a resource

Compare EPA + DHA value

Use two labels and prices to calculate cost per gram of EPA + DHA. The result compares label amounts and price; it does not rank product quality.

Keep a product evidence record

Print a blank worksheet for the exact product, market, source dates and package lot. Write down what matches and what remains unknown.

Both resources are free to use without an account or email signup.

A short description for your readers

For an editorial resource list or article, describe what the calculator actually does:

SupplementChecker’s free omega-3 value calculator compares two labels by cost per gram of EPA + DHA. Enter the price, servings per container and EPA/DHA amounts per serving, then print the comparison. It compares label arithmetic, not health benefits or product quality.

Share an existing evidence profile

Brand pages include a copyable iframe. It displays a reviewed score when available, or an unrated status while coverage is incomplete.

  1. Find the brand and open its profile.
  2. Locate “Share this evidence profile”. Choose Small, Medium or Large and use its Copy button.
  3. Paste the existing iframe snippet into your site’s HTML/embed block. Preview it at the width your readers will use.
  4. Read the linked profile’s coverage, dates and limitations before describing its findings.

An evidence-profile embed is not a certification seal, product endorsement or proof of a package lot. It displays the latest published profile; publication does not mean every source was checked again. Keep those distinctions in any accompanying copy.

For the underlying checks, read how to check third-party-testing evidence. Check the dates and scope of each record you rely on.
