Abstract

For the past 50 years, repeated analyses of human milk have shown an average of 20 IU/liter of vitamin D activity. Following the 1977 report of Lakdawala and Widdowson,¹ which found that a large amount of water-soluble vitamin D sulfate was present in the whey (or water-soluble) fraction of human milk, the previous studies appeared to be in question. This study by Lakdawala and Widdowson reportedly confirmed earlier reports from Japan^2-4 and France⁵ which not only demonstrated large quantities of vitamin D sulfate in human milk, but also strongly suggested that this vitamin D metabolite had biologic activity in rats.
