Vitamin D helps regulate the renin-angiotensin-aldosterone system (and thereby blood pressure), vascular cell growth, and inflammatory and fibrotic pathways [ 118 ]. Vitamin D deficiency is associated with vascular dysfunction, arterial stiffening, left ventricular hypertrophy, and hyperlipidemia [ 119 ]. There is some evidence that having a vitamin D deficiency does cause hair loss and other hair problems. Vitamin D stimulates hair follicles to grow, and so when the body does not have enough, the Given that vitamin B12 is found primarily in animal products, vegans and vegetarians may also be at a higher risk of deficiency ( 15 ). Furthermore, a deficiency in B vitamins may lead to Several cell types of the immune system express Vitamin D receptor, and hence the use of Vitamin D in immune regulation has some potential. Furthermore, Vitamin D deficiency leads to dysbiosis of gut microbiome and reported to cause severe colitis. Vitamin D supplementation is low cost and available and can be a therapeutic option. Vitamin D is classified as an immunomodulatory hormone that is synthesized because of skin exposure to sunlight. It is known to come into play during the regulation of hormone secretion, immune functions, cell proliferation, and differentiation. Its deficiency can cause many diseases and their associated pleiotropic effects. Both vitamin D 3 formed in the skin and vitamin D 3 absorbed from the digestive tract, travel to the liver, where they are hydroxylated at carbon 25 to form clacidiol (also called 25-hydroxy vitamin D 3, abbreviated as 25(OH)D) by liver 25-hydroxylase, CYP2R1 and CYP27A1. 25(OH)D is the major circulating vitamin D metabolite and a reliable indicator of vitamin D status. It is not clear from these studies if low vitamin D is a cause, a consequence or an innocent bystander in the development of these common thyroid conditions. It is possible that low vitamin D may permit the under-performing immune system to facilitate progression of thyroid disease. Equally, it is also possible that people with thyroid diseases Despite the stream of “good news” about vitamin D, the supplement’s prospects to prevent mental health disorders in adults remain dim.
