Excellent value for money High-dose formula with 220 µg selenium per tablet (sodium selenite and L-selenomethionine). Complex of the two ideally complementary forms sodium selenite (inorganic selenium) and selenomethionine (organically bound selenium). Highly bioavailable selenium complex High bioavailability thanks to a combination of different selenium forms. The organic (L-selenomethionine) and inorganic (sodium selenite) selenium compounds complement each other perfectly. Sodium selenite is absorbed more quickly by the body and thus represents the most readily bioavailable form of selenium. Selenomethionine, a natural component of food, has a higher bioavailability than selenium.
