Also, vitamin D is a known inhibitor of the enzyme tryptophan hydroxylase (TPH), which synthesizes serotonin (5-HT). Thus, low vitamin D levels mean higher activity of TPH and thus more serotonin production. Elevated tryptophan and serotonin have already been linked to premature graying and anti-serotonin drugs of the ergot class (e.g. bromocriptine) have been shown to reverse hair graying in humans.<\/p>\n<p><a href=\"https:\/\/pmc.ncbi.nlm.nih.gov\/articles\/PMC3746220\/\">https:\/\/pmc.ncbi.nlm.nih.gov\/articles\/PMC3746220\/<\/a><\/p>\n<p><a href=\"https:\/\/timesofindia.indiatimes.com\/etimes\/wellness\/premature-gray-hair-causes-b12-vitamin-d-and-copper-deficiency-explained\/articleshow\/132173522.cms\">https:\/\/timesofindia.indiatimes.com\/etimes\/wellness\/premature-gray-hair-causes-b12-vitamin-d-and-copper-deficiency-explained\/articleshow\/132173522.cms<\/a><\/p>\n<p>&#8220;&#8230;Researchers have also flagged low vitamin D and calcium as common in people with premature graying. <strong><span style=\"text-decoration: underline;\">A 2013 case-control study our of a semi-urban Indian population found deficiencies in serum calcium and vitamin D3 among<\/span> the group with premature graying<\/strong>.&#8221;<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Give the role of both of these nutrients in cellular energy production, this finding is not at&#8230;<\/p>\n","protected":false},"author":1,"featured_media":0,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[2],"tags":[1338,50,1788,1187,47,1655,49],"class_list":["post-3074","post","type-post","status-publish","format-standard","hentry","category-science","tag-calcium","tag-cholecalciferol","tag-graying","tag-hair","tag-serotonin","tag-tryptophan","tag-vitamin-d","wpcat-2-id"],"_links":{"self":[{"href":"https:\/\/haidut.me\/index.php?rest_route=\/wp\/v2\/posts\/3074","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/haidut.me\/index.php?rest_route=\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/haidut.me\/index.php?rest_route=\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/haidut.me\/index.php?rest_route=\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/haidut.me\/index.php?rest_route=%2Fwp%2Fv2%2Fcomments&post=3074"}],"version-history":[{"count":1,"href":"https:\/\/haidut.me\/index.php?rest_route=\/wp\/v2\/posts\/3074\/revisions"}],"predecessor-version":[{"id":3075,"href":"https:\/\/haidut.me\/index.php?rest_route=\/wp\/v2\/posts\/3074\/revisions\/3075"}],"wp:attachment":[{"href":"https:\/\/haidut.me\/index.php?rest_route=%2Fwp%2Fv2%2Fmedia&parent=3074"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/haidut.me\/index.php?rest_route=%2Fwp%2Fv2%2Fcategories&post=3074"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/haidut.me\/index.php?rest_route=%2Fwp%2Fv2%2Ftags&post=3074"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
