Selenium

Clinical studies have also shown that selenium can reduce the amount of antibodies that target the thyroid in autoimmune thyroiditis such as Hashimoto’s or Graves’ diseases.

A Daily Dose of an Essential Antioxidant Mineral

  • Thyroid Regulation

    The largest concentrations of selenium are found in the thyroid. Selenium powers enzymes that convert the thyroid hormone T4 to T3. T3 plays a role in growth, temperature regulation, and metabolism. 7

  • Strengthen Immune Response

    Selenium plays an important function in the regulation of the immune system. The antioxidant properties of selenium can help balance the immune system by neutralizing free radicals and supporting white blood cell function.8

  • Heart Health

    The antioxidant properties of selenium can help to maintain a healthy heart and cardiovascular system.9

  • Antioxidant Protection

    Our own immune system uses free radicals to fight the bad guys, but free radicals are messy little troublemakers. The gunk they leave behind leads to inflammation and oxidative stress. Antioxidants gobble up the gunk before it can do harm.10

  • Ongoing Research

    Selenium may also reduce the risk of certain cancers. Some scientific evidence suggests that consumption of selenium may reduce the risk of certain forms of cancer. However, FDA has determined that this evidence is limited and not conclusive.

Easy, Vegan and Nut-free Way to Boost Selenium

200 micrograms of L-Selenomethionine; an optimal daily dose you can count on

Selenium is an essential mineral that is a star player on the Antioxidant A-Team along with Vitamins A, C and E. It helps to support and balance our immune system by neutralizing free radicals, promoting overall health and wellness.

Our bodies need selenium in a big way, as it is part of a well balanced diet.1 Produce today may be grown in soils that are depleted in minerals such as selenium.2 (Plants can only absorb selenium; they don’t actually produce it!) We get selenium in our diet by eating plants with selenium or eating animals that ate lots of plants containing selenium. Mineral-depleted soil means selenium-deficient food.

The other challenge is that there aren’t a lot of foods that accumulate much selenium, even if they are grown in selenium-rich soil.3 Brazil nuts offer the highest concentrations (eating two per day can give you a daily dose),4 but we’ve found that it’s surprisingly hard to get your hands on quality nuts. What you typically find in the grocery store might be rancid or have mold, so it is important to check what you buy and take note of the flavour.5

Fish such as tuna and halibut are the other big source of selenium, but friends don’t let friends get their daily dose of selenium from fish. If you eat seafood, you are probably aware that it’s wise to limit consumption to minimize exposure to heavy metals such as mercury.6

This is pure selenium with no additional nutrients. It is formulated for maximum bioavailability and easy digestion. Because what’s the point of taking a supplement if your body isn’t able to absorb and use it?

The ingredients inside Selenium

  • Optimal Daily Dose

    Unless you live on a Brazil nut farm, it’s hard to get the optimal daily dose of selenium from your diet. Just one capsule a day gives you an easy 200 micrograms.

  • Nut-free and Vegan

    We want our vegan friends and those with nut allergies or sensitivities to get enough of this important nutrient. You need it, friends!
