Hypothyroidism treatment usually involves thyroid hormone replacement medications. They include synthetic thyroid hormones levothyroxine (Synthroid, Unithroid, others) and liothyronine (Cytomel), as well as thyroid extract supplements. Calcium supplements \u2014 or antacids containing calcium \u2014 can interfere with how the body absorbs those medicines.<\/p>\n<p>The problem happens mainly if you take thyroid hormone replacement and calcium supplements at or near the same time. Follow these steps:<\/p>\n<ul>\n<li>Don&#8217;t take calcium supplements or antacids at the same time you take thyroid hormone replacement.<\/li>\n<li>Take any products containing calcium at least four hours before or after taking thyroid hormone replacement.<\/li>\n<\/ul>\n<p>Other supplements &mdash; especially those containing iron &mdash; also can interfere with thyroid hormone replacement. Some foods and other medicines can too. If you are prescribed thyroid hormone replacement, tell your healthcare professional about all the other medicines and supplements you&#8217;re taking.<\/p>\n<\/div>","protected":false},"excerpt":{"rendered":"<p>Calcium supplements can interfere with how the body absorbs medications used to treat hypothyroidism.<\/p>","protected":false},"author":1,"featured_media":0,"comment_status":"closed","ping_status":"closed","template":"","tags":[1686,1685,1682,1684],"class_list":["post-50564","mayo","type-mayo","status-publish","hentry","tag-anatomical-structure","tag-condition","tag-person-group-concept","tag-theme-of-focus","content_type-answers"],"acf":[],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v27.3 - https:\/\/yoast.com\/product\/yoast-seo-wordpress\/ -->\n<title>Hypothyroidism: Can calcium supplements interfere with treatment?
