About Creatine Calculators

Creatine Calculators is a small, independent site with one job: turn the published creatine research into a dose you can actually measure for your own body weight, without wading through forum arguments or supplement marketing.

Where the numbers come from

Every rule in the calculators traces to a citation listed at the bottom of the page that uses it: the International Society of Sports Nutrition's position stand on creatine (Kreider et al., 2017), Hultman's 1996 muscle-loading study, Candow's trials in older adults, the Smith-Ryan lifespan review of creatine in women, the National Academies' water intake references, and the 2024 independent laboratory tests of creatine gummies. We re-read the literature each year and update the rules when the evidence moves.

How the estimates work

Each calculator converts your weight to kilograms, applies the per-kilogram rule from the research, clamps the result to the range the studies actually used, and converts it to scoops, teaspoons, capsules or gummies. They assume creatine monohydrate — the form used in essentially all the research. They are educational estimates for healthy adults, not medical advice.

Who runs this

The site is built and maintained by a small business owner in Kentucky who got tired of every "how much creatine" answer being a 3,000-word article that ended in "it depends." If you spot an error, disagree with a rule, or have a calculator you wish existed, let us know.

How the site makes money

The site shows ads and may include affiliate links to creatine products. That never changes the math, and we don't sell or recommend any particular brand. If you give us your email to unlock a result, we use it to send an occasional dosing reminder or research update, and you can unsubscribe with one click. We never sell it.
