Contact Us

We read every message. Whether you found a number that looks off, you have an idea for a calculator we should build next, or you just want to say the site helped you, this is the place.

What to write about

A few things people commonly contact us about:

Corrections. If a figure, formula, or food protein value looks wrong, tell us which page and what you spotted. We check corrections against our sources and update the page.

Calculator ideas. If there is a protein question you wish had its own tool, describe it. Several of our calculators started as reader suggestions.

Content feedback. Too technical? Too basic? Missing a question in the FAQ? We rewrite sections regularly based on this kind of feedback.

Anything else. Partnerships, press, or just saying hello are all welcome.

What happens after you send

We aim to reply within two to three business days. Corrections get priority, because wrong numbers help nobody. Please include the page URL if your message is about something specific on the site. It saves us both a round of back-and-forth.
