Most supplement questions have a number for an answer, and the number is usually missing from the bottle: how many grams of creatine for your body weight, how much actual magnesium is in a 500 mg capsule, whether the 50 mg of an ingredient on a label is anywhere near the dose the studies used, and how long the coffee you drank at four o’clock will still be in you at bedtime. These free tools work that out from what you type, in a few seconds, on a phone as well as a laptop. Nothing to sign up for, nothing to install.
Dose Calculators
A number in, a dose out — with the official limit beside it and the source named.
Label & Value Checkers
What is really in the bottle, whether it reaches the studied dose, and what it costs you a day.
Brain Tests & Trackers
Measure yourself now, start something, and measure again in four weeks.
Where the numbers come from
Every dose, limit and conversion here is taken from an official source and named on the page — the National Institutes of Health Office of Dietary Supplements, the FDA, the published Dietary Reference Intakes, or a peer-reviewed position stand — with the date it was last checked. Where good sources disagree, you see both numbers and who said each one, because pretending there is a single answer would be the easiest way to be wrong.
What these tools will never do
They do not diagnose anything, they do not tell you a supplement treats a condition, and they do not check whether a supplement interacts with your medication — that last one is a job for your pharmacist and for a proper drug-interaction database, and doing it badly would hurt somebody. Nothing here recommends a dose above the official upper limit. This is not medical advice: talk to your doctor or pharmacist before starting anything new, especially if you take blood thinners, antidepressants or blood-pressure medication.
What you type stays on your device
Every calculation runs inside your own browser. A weight, a lab result or a label you type is never sent anywhere and never stored by us.
Share an answer, or keep it
Every result has its own link. Copy link saves exactly what you entered, so you can send a dose to someone or open it again on your phone in the shop without filling the form in twice.
Put a tool on your own site
Every tool has an Embed button. It gives you a short piece of code to paste into a page on your own blog or forum. The tool works there exactly as it does here, free, with a credit line linking back to Valentino’s Naturals.
