Selenium

The free radical scavenger

How much do I need?

Below are the current Dietary Reference Intakes (DRIs) established by the Health and Medicine Division of the National Academy of Sciences (formerly known as the Institute of Medicine).

  • Infants 0 - 6 months - 15 mcg
  • Infants 7 - 12 months - 20 mcg
  • Children 1 - 3 years - 20 mcg
  • Children 4 - 8 years - 30 mcg
  • Boys and Girls 9 - 13 years - 40 mcg
  • Teenagers 14 - 18 years - 55 mcg
  • Men and Women 18 years and older - 55 mcg
  • Pregnant Women 14 - 50 years - 60mcg
  • While Breastfeeding 14 - 50 years - 70 mcg

Selenium at high levels (400+ mcg daily) can be toxic. Since selenium is found naturally in many plant and animal products, we’ve included 14 mcg of selenium in our Men’s Formula, and in our PhD Men’s Formula, PhD Women’s Formula, PhD Prenatal Formula, PhD Women 50+ Formula and PhD Men’s 50+ 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

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. So, we include selenium to help fill any nutritional gaps.

How do I get it?

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