In human monocytes, the activation caused by pathogens via TLR up-regulates genes associated with the conversion of 25OH to 1,25OH and VDR. The addition of vitamin D to monocytes in culture causes the up-regulation of VDR downstream genes such as cathelicidin [38–40]. The peptide ...

Most individuals naturally generate adequate amounts of vitamin D through ordinary dietary intake of vitamin D (in some foods like eggs, fish, and cheese) and natural photochemical conversion of the vitamin D3 precursor 7-dehydrocholesterol in the skin via exposure to sunlight 9,12,13,14. Conve...
Only by understanding the unit conversion and correct calculation can we effectively avoid the risk of excessive vitamin D intake. So, again, the recommended intake of vitamin D is 400 IU per day, or 10 micrograms. So need 400 IU of vitamin D every day, how should we give the baby suppl...

Vitamin D, primarily in the form of calcitriol (1α,25-dihydroxy-vitamin D), facilitates calcium absorption in the gut. When vitamin D levels are insufficient, the parathyroid glands respond by secreting increased amounts of PTH. This hormone, in turn, stimulates the conversion of calcidiol (...
Cholecalciferol requires hepatic 25-hydroxylation for conversion to 25(OH)D, a process that may be impaired in obese individuals due to hepatic dysfunction or metabolic irregularities [9,10]. Calcifediol bypasses this step and can be used regardless of BMI and vitamin D baseline status. Thanks to...
[18]. When vitamin D levels are low, the TLR stimulation of human macrophages results in a number of significant reactions, including (1) increased expression of VDR [17], (2) conversion of 25(OH)D to its most biologically active form, 1,25-dihydroxyvitamin D [1,25(OH)2D] [19], ...
