How many pills do you actually need?
Enter what is in your capsule, tablet or scoop. PillMath tells you how many to take to reach the official daily intake (EFSA or NIH) or a dose used in published studies, and warns you before you pass the upper limit.
Your label
Enter the amount in one unit, in mg, µg, g or IU. PillMath converts salt weights (like magnesium citrate) to the real mineral.
Your goal
Official intake for your age and sex, or a dose that was actually tested in a study, with the paper one click away.
Your answer
How many a day or a week, how long the bottle lasts, and how close you are to the upper limit.

Where the numbers come from
Official values come from EFSA (Europe) and the US National Academies, used by NIH. Study doses come from randomised trials and meta-analyses, each linked to PubMed or the publisher. Where a study found no benefit or harm, we say so.
