No. All content on this site is strictly for educational purposes. Our guides aim to break down complex dosing formulas and concepts into plain language so you can better understand how insulin works, but they do not replace the personalized guidance of your diabetes care team.

The content is written and maintained by our founder, Ryan Mitchell, leveraging his background in the healthcare and pharmaceutical industry. Every article is meticulously researched and referenced against established clinical guidelines, such as the ADA Standards of Care.

We review our core educational guides annually or whenever major updates to clinical guidelines (like the ADA Standards of Medical Care in Diabetes) are published. You can always check the "Last reviewed" date at the bottom of the page.

While our calculators provide mathematical estimates based on your specific inputs, these educational guides explain the underlying clinical theory. They break down the formulas and rules (like the 500 Rule or 1800 Rule) so you understand exactly how those numbers are derived.

All concepts and formulas discussed in our guides are sourced from peer-reviewed medical literature, clinical textbooks, and established organizations such as the American Diabetes Association (ADA) and the Endocrine Society. We publish and cite these sources directly.

Yes. Healthcare professionals, diabetes educators, and clinicians are welcome to share our guides as supplementary reading materials to help patients understand the basics of insulin therapy. However, they must not be used as a substitute for your individualized clinical instructions.
