    This blog is in response to Dr Briffa's post here. as I keep having problems commenting on his blogs.

    While 44ng/ml is sufficient to not only maximize uptake of calcium (>32ng/ml) and ensure maximum bone mineral density (>42ng/ml), pregnant and nursing mothers should be aware that in order to maximize the amount of vitamin D3 in human breast milk 6400iu/daily was found to be necessary to raise (>58ng/ml) at latitude 32.
    This is detailed in the Taylor, Wagner and Hollis paper.
    Vitamin D supplementation during lactation to support infant and mother.
    Although 4000iu/daily met the mothers daily needs in full it left babies being born with lower 25(OH)D status than required for optimum calcium absorption

    They also found DAILY use of supplements was required by pregnant and nursing mothers to ensure an even daily Vitamin D3 supply to the foetus & baby.
    It makes virtually no measurable difference for everyone else if you supplement daily or weekly.

    While Dr Briffa will not be lactating he may be interested seeing in the
    Grassrootshealth chart showing disease incidence by 25(OH)D status.
    this may encourage him to go just another 10ng/ml higher and a bit nearer to the natural level at which human breast milk flows replete with D3."
