You'd have to get follow up to see if Vitamin D has gone up after taking it.

I was Wrong on the internet (lots of food has vitamin D including Eggs and Mushrooms): Vitamin D supplements may not be absorbed as digestion isn't the normal process for obtaining it.

"Very few foods in nature contain vitamin D. The flesh of fatty fish (such as salmon, tuna, and mackerel) and fish liver oils are among the best sources [1,11]. Small amounts of vitamin D are found in beef liver, cheese, and egg yolks. Vitamin D in these foods is primarily in the form of vitamin D3 and its metabolite 25(OH)D3 [12]. Some mushrooms provide vitamin D2 in variable amounts [13,14]. Mushrooms with enhanced levels of vitamin D2 from being exposed to ultraviolet light under controlled conditions are also available."

Wouldn't a doctor simply test? I know when I was really low, the doctor scheduled me for a blood test after 3 months of prescription-dose vitamin D pills. We've also spot checked since then.

Yeah, when I got back for my next checkup, I definitely plan to ask my doctor to order the Vitamin D test again so we can see how it's changed over time.
