Jod

Mineral Evidence: strong

Overview

Iodine is an essential trace mineral required to synthesize thyroid hormones T3 and T4, which regulate metabolism and fetal neurological development. Adults need 150 mcg daily; pregnant women 220 mcg. Upper limit is 1,100 mcg/day. Both deficiency and excess harm thyroid function: deficiency causes hypothyroidism and goiter; excess can inhibit thyroid hormone synthesis and trigger autoimmune thyroid disease. Seaweed contains highly variable iodine levels. People with thyroid conditions should consult a doctor before supplementing.

Selen Info

Selen ist essentieller Cofaktor der Jodothyronin-Deiodase (ID1/ID2/ID3), die T4 in biologisch aktives T3 umwandelt. Eder et al. (1997 J Nutr, PMID: 9187638): Selen-Jod-Interaktion beeinflusst T4/T3-Ratio und Schilddrüsen-Glutathionperoxidase-Aktivität signifikant. Selenmangel bei hoher Joddosis kann Schilddrüsenschäden verstärken.

Bei Jod-Supplementierung auf ausreichende Selenversorgung achten (optimal: 55–100 µg/Tag). Besonders relevant in Jodmangel-Regionen und bei Schilddrüsenerkrankungen. Beide können gleichzeitig eingenommen werden.
