How did the doctor know her vitamin levels were low? I once asked a doctor if the vitamins in our body can be measured, and he said it can't be done, is not something you can measure.
- scarlac 6y agoIt can be measured with a blood test: > The most accurate way to measure how much vitamin D is in your body is the 25-hydroxy vitamin D blood test. https://www.webmd.com/diet/guide/vitamin-d-deficiency https://www.webmd.com/diet/guide/vitamin-d-deficiency
- ryder9 6y agoBlood test, had it done myself and found low levels of B12 & D, for which I took initially large doses and now take over the counter supplements
- gnulinux 6y agoI regularly blood-test my vitamin D and B levels since I live indoors a lot (not an outside person) and have a slight vit. B absorption problem (I don't absorb it as efficiently as normal people) so I need to take supplements even if I eat healthily.
