Saturated Fats, Cholesterol Lard and Vitamin D

[Persej]

I am not sure how did we get to the statement that human milk is not an adequate source of vitamin D, and that we need to supplement babies, and everybody else, with cholecalciferol. In this study, human milk does have quite a bit of vitamin D, but the majority of it is in the calcifediol form, just like in cow's milk:

The same results can be found here:

A possible explanation is given here:

A review is given of the results of vitamin D determinations in human and cow's milk using physico-chemical methods. Thereby only parent vitamin D is determined. Further, the results obtained with protein-binding assays are discussed in detail. With the aid of these newer methods the concentrations of hydroxylated vitamin D derivatives can also be measured. A comparison of the concentration of these vitamin D metabolites in human milk and infant formulas based upon cow's milk suggests that the higher anti-rachitic activity of human milk is connected with its higher concentration of 25-hydroxy-vitamin D.
