About Us

iutomg.com was created to solve a very specific, very common headache: converting International Units (IU) into milligrams (mg), micrograms (mcg), and back again for vitamins and supplements — accurately, quickly, and without digging through confusing tables or inconsistent articles.

Many people see “IU” on a label, search for a formula, find multiple conflicting answers, and still feel unsure if they’re reading their supplement correctly. This site is built to make that step clean and transparent: clear default factors for supported vitamins, the ability to adjust potency values when needed, and instant results in a modern, mobile-friendly interface.

What we care about

• Clarity in conversions. Every calculator is designed so you can see exactly how IU and mg relate for the selected vitamin or potency, instead of guessing.
• Educational, not prescriptive. We help you understand numbers and labels. Final dosage decisions stay between you and your healthcare provider.
• Privacy by design. You don’t need an account to use iutomg.com. Inputs stay in your browser, and we keep tracking minimal.
• Fast, focused experience. No cluttered dashboards, no bloated features. Just a dedicated IU-to-mg tool that loads fast and works well on both desktop and mobile.
• Transparency about limitations. Different regions, vitamins, and formulations can use different standards. We highlight that, instead of hiding it behind fine print.

How iutomg.com helps

• Instant IU ⇄ mg/mcg conversions for supported vitamins and supplements.
• Adjustable potency values so you can match what’s printed on your specific product label instead of relying on a one-size-fits-all assumption.
• Clean explanations that remind you to verify with packaging, guidelines, or a professional.
• A layout tuned for quick use: simple fields, clear results, and supporting FAQs.

What’s next

• Expanding support and clarifications for more vitamins and supplement categories.
• Improved explainers on how conversion standards differ between authorities and regions.
• Optional tools to compare products or strengths side-by-side (while staying privacy-friendly).
• Continuous UI refinements to keep the experience fast, accessible, and distraction-free.
