Windaus and colleagues (539) synthesized 7-dehydrocholesterol and the demonstrated its conversion to another antirachitic substance, vitamin D3, which was found to be identical to the antirachitic component of cod liver oil (73) and to be produced in the skin by ultraviolet light (244, 403)...
000 IU of vitamin A and 100,000 IU of vitamin D3. The two has no antagonistic effect. And their production and use are very convenient. Vitamin D can increase the absorption and metabolism of calcium and phosphorus, prevent swine rickets, and promote the development of teeth and bones. ...

D3 in these mice, have confirmed the role of CYP2R1 in the hydroxylation of vitamin D at C-25.10 However, synthesis of low levels of 25 (OH)D3 in these mice suggests that other 25-hydroxylases, yet to be identified, are also involved in the conversion of vitamin D to 25(OH)D3....
Repeated ANOVA, ANOVA tests, and Kolmogorov–Smirnov normality tests on the SPSS program were used to statistically analyze the results. Result In the dose groups of 10,000 IU and 5000 IU, significant increases in the levels of vitamin D, TLR-2, and TLR-4 were observed at weeks 4 and 8...
