<iframe src="https://healthbritannica.com/embed/supplement-stack-calculator.html" width="100%" height="620" frameborder="0" style="border:1px solid #2a2a33;border-radius:8px;background:#060608;" title="Supplement Stack Calculator by Health Britannica"></iframe> <script> window.addEventListener('message',function(e){ if(e.data&&e.data.type==='resize'&&e.data.height){ document.querySelector('iframe[src*="healthbritannica.com/embed"]').style.height=e.data.height+'px'; } }); </script>

Sizing

Default height="620" shows the goal selector. After building a stack, the widget expands to show results -- include the auto-resize script above for seamless resizing, or set height="1600" for a fixed size that fits all goals selected.

Questions

Is this really free?

Yes. The widget includes a small "Powered by Health Britannica" link at the bottom. That's it. No ads inside the widget, no data collection, no usage fees.

Does this work with WordPress / Shopify / Ghost?

Yes. Any platform that supports iframes. In WordPress, use a "Custom HTML" block. In Shopify, use the HTML editor in any page or blog post. In Ghost, use an HTML card.

Will this slow down my site?

No. The iframe loads asynchronously. All logic runs in the visitor's browser. Total payload is under 15KB, smaller than most images.

Are the supplement recommendations evidence-based?

The dosages and pairings reflect commonly cited ranges from peer-reviewed research and clinical guidelines. Each supplement links to a full Health Britannica article with sources. Always consult a healthcare provider before starting a new supplement regimen.
