The free radical scavenger

How much do I need?

The current recommended daily intake (RDI) for selenium is 55 mcg for adults, 60 mcg for pregnant women, 70 mcg for breastfeeding women, 40 mcg for children 9-13, 30 mcg for children 4-8, and 20 mcg for children 1-38.

Selenium at high levels (400+ mcg daily) can be toxic, and since selenium is found naturally in many plant and animal products, we’ve included 14 mcg of selenium in our Men’s Formula to safely supplement your dietary intake.

We always recommend you check with your healthcare practitioner before taking any of our products.

Why we include it

A growing body of research and clinical studies have demonstrated the efficacy of selenium in maintaining a healthy prostate5,6,7. Furthermore, selenium is an essential mineral that the body needs but can’t make on its own. At SmartyPants, we are committed to staying on top of the latest in health science and to keeping you in tip-top shape. This is how smart men – and SmartyPants –  do healthy.

How do I get it?

Selenium can be destroyed during food processing, so try to source selenium from whole, unprocessed foods when possible.
