Supplement Tools and Calculators

A set of free tools for reading supplement labels the way a scientist would: the real dose behind the marketing, the elemental amount behind the compound, and the value behind the price. Each one is built on government and peer-reviewed sources.

These tools were built by Serge (MSc) using established science and government sources. My academic background covers plant biology, environmental biology, and biogeochemistry. They are for educational purposes and give practical guidance, not professional advice.
