Reacted Selenium 200 mcg by Ortho Molecular Products

If you’re exploring selenium for thyroid health, this dose fits adults with low or low‑normal intake who want a clinically used amount. It’s most relevant if your Selenium, Serum or Plasma is low, you rarely eat seafood or Brazil nuts, follow a vegan diet, or have thyroid autoimmunity with elevated Thyroid Peroxidase Antibodies. People with gastrointestinal disorders that impair absorption, those on dialysis, and postpartum women with thyroiditis are also candidates. If your level is replete, extra selenium is unlikely to help and can be counterproductive.

Selenium is built into selenoproteins that run key reactions: glutathione peroxidase (an enzyme that neutralizes peroxides before they damage cells), thioredoxin reductase (cellular redox control), and deiodinases (the enzymes that convert T4 into active T3 thyroid hormone). In thyroid autoimmunity, adequate selenium can modestly reduce antibody activity in some patients and smooth oxidative stress in the gland. The glycinate chelate is a gentle, well‑absorbed form comparable to selenomethionine, with less stomach upset than inorganic salts like sodium selenite.

Take one capsule daily with food to minimize nausea; morning or evening is fine. This is a full, not a micro, dose, so avoid stacking it with high‑selenium multivitamins or frequent Brazil nuts. Recheck Selenium, Serum or Plasma, TSH, Free T4, T3, and Thyroid Peroxidase Antibodies after 8 to 12 weeks. Antibody changes, when they occur, are usually seen by 3 to 6 months of steady intake.

If your selenium level is already high, skip supplemental selenium. Watch for signs of excess, like brittle nails, hair shedding, digestive upset, or a garlic‑like breath odor, and stop if these appear. Long‑term high intake has been linked to higher type 2 diabetes risk in some studies, so don’t exceed needs. Pregnancy is a time to keep intake moderate; use under clinician guidance and avoid combining multiple selenium products.

Selenium isn’t an antiviral or a shortcut for “immune boosting,” and it won’t replace thyroid hormone if you’re hypothyroid. Its lane is correcting low status so selenoproteins work properly. Some, but not all, patients with thyroid autoimmunity see reductions in Thyroid Peroxidase Antibodies. If your hs-CRP (a general inflammation marker) is high for other reasons, don’t expect selenium alone to normalize it.
