I was tested last May, and my level was actually a little too high! Several years ago when I was tested it was at the lower level of normal, so I started taking a 2,000 mg tablet of Vit. D in the morning, and another in the evening. Since I live in NE Ohio, I get a lot of sun in the summer from jogging, so I have to cut back a little on the pills. There's no such thing as sun around here in the winter, but I can still keep my D up with just the supplements when it's gloomy (I still go outside to jog, though!). I'm going to be 70 next month, so it can be done at any age.
