Embed our calculators on your site

Every ProteinBenchmark calculator is free to embed. Copy the iframe snippet — no API key, no signup, no JavaScript bundle to host. Attribution is appreciated but not required; a small "Powered by ProteinBenchmark" footer appears in each embed.

A few honest notes

The heights above are tested defaults. If your audience uses a lot of metric input or the calculator runs longer (GLP-1, snack finder), bump the height up — the embed itself does not scroll, the parent page does.
The embed view carries a rel="canonical" back to the bare calculator URL, so it will not compete with your page for search rankings — search authority stays consolidated on our canonical page, not the embedded copy.
If you would like a co-branded version (your logo in the footer instead of ours, in exchange for a dofollow backlink in your page header), email us at info@proteinbenchmark.com .
The math behind every calculator is documented on the methodology page — feel free to cite it in your content.
