Selenium
Sodium selenite · Se
Mechanism
Selen ist Bestandteil selenabhängiger Enzyme (u. a. Glutathionperoxidase) und wirkt im antioxidativen System synergistisch mit Vitamin E. Viele mitteleuropäische Böden sind selenarm. Selen hat eine enge therapeutische Breite — Über- und Unterversorgung sind beide klinisch relevant.
Cautions
- · Narrow therapeutic margin — selenosis on overdose
- · Supplement long-term only with blood-level monitoring
