Hello, I would like to know if anyone could assist me with vitamin D dosing. I am having a 7 minute sun bed per week, weight 13stone, fair skinned. Any recommendations ? I have read that vitamin d3 has a long half life so why take it daily, rather than one large dose per week ?

    For a fair skinned person it takes about 15 minutes per day to get adequate amounts. Since you weigh a little more than 150lbs, you might have to extend that time a little more. Don’t forget that large amounts of skin must be exposed.
    The reason for “daily” is this. It use to be thought that all Vitamin D was “activated” thru the kidneys and in turn this regulated calcium levels. They thought this was Vitamin D’s only job.”The modern understanding of vitamin D includes this endocrine signaling, but also understands that vitamin D is also activated inside many other cells, where it is used to signal the DNA machinery inside that cell (autocrine signaling) or inside adjacent cells (paracrine signaling) to up- or down-regulate genes that code for specific proteins.” This would mean that Vitamin D is needed everyday to operate efficiently.

    Hi, thank you for providing me with that insightful information, but my question still has not been answered completely. I would like to know how much vitamin D3 supplement I should be taking per day based on my weight and skin colour ? I am currently taking 5000IU per day, with vitamin c all day due to the short half life of vitamin c, ZMA and msm 10g per day, one in dose of 5g in the morning and one dose of 5g at night, due to the 12 hour half life of msm.

    Do you have an health issues? If not 6-7000iu a day should be fine for your weight.
