## About
Crack open a single Brazil nut and you hold nearly a week's measure of selenium. A handful is not always practical, though, and the nuts can vary tenfold in strength depending on where the tree grew. Hence this small, modest tablet: matte, beige and easy to mistake for chalk.Selenium was only confirmed as essential to human health in the middle of the last century, later than most minerals on this shelf, and the body builds enzymes specifically to use it. Soil selenium varies enormously by region, which is how the deep-rooted Brazil nut tree, drawing from rich Amazonian ground, became the mineral's unlikely mascot.Selenium also has a narrower safe range than most minerals; here, more is not better. Each tablet is measured precisely, so you are not left to the guesswork of a handful of nuts.DetailsForm: small tablet, measured preciselyDaily amount: one tabletUpper limit: under 400 mcg a day from all sourcesHow to useTake one tablet daily. On days you also eat Brazil nuts, consider skipping the tablet, since the two add up quickly, and keep your total under 400 mcg a day from all sources.A small mineral, easily overlooked; keep it with your morning routine.
