Sometimes it is not the amount of a particular vitamin we take but the other things that may affect its absorption. A and D are prime examples since they as well as many herbs (tumeric/cucurmin) are fat soluble. So... here we all are ladies, watching our waistlines and not eating enough fats (or meat) when we take some of these supplements. I think it might play a bigger part than what we initially think. Always take supplements with a meal and think about how "fatty" a meal might be so you time certain supplements with the right meal. Just some thoughts here. Secondly, as we age, it is more difficult to convert D3 to its useable form (and this is the form they test for in the blood). First the liver needs to make the first conversion and then the kidneys make the second conversion. These steps become more and more inefficient. Secondly, I wouldn't think chemo would help the functioning of either of these 2 organs either - but ageing is a bonefide culprit and why the elderly are recommended even more. Lastly, diminishing thyroid function also affects vitamin D absorption and conversion.
