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>

<p dir="auto">“…Researchers have also flagged low vitamin D and calcium as common in people with premature graying. <strong>A 2013 case-control study our of a semi-urban Indian population found deficiencies in serum calcium and vitamin D3 among the group with premature graying</strong>.”</p>
