There have been reports of molybdenum in milk since before 1951. However, supposedly "there [is] no data on bioavailability in cow's milk" after all these years. Most sources I find claim milk contains somewhere on the order of 50 μg/L. I'm having troubles finding more detail. Mostly I'm curious about my daily intake, and possible cheap but still mostly healthy meal replacements for lazy days.
How much molybdenum can I expect (as a low ball estimate) to count towards the daily RDA of 45 μg from the about 35 μg in three cups of milk?
Perhaps the best way to answer this is to find out in what compounds the molybdenum are in in milk and see if there's any details on those compounds' bio-availability. I know they said the nutrient fed to the cows to increase the molybdenum content was ammonium molybdate, which, along with sodium molybdate and potassium molybdate, should be bioavailable (along with most soluble molybdenum sources). The Soylent discussion site (which is oddly appropriate to why I'm asking), has other citings on their bio-availability listings which confirm this. If I find an answer, I'll post it.
