The best dietary sources for vitamin D include oily fish like salmon and mackerel, beef liver, egg yolks, and fortified dairy products.

Most people in northern latitudes (I was listening to an expert yesterday who said in the US that's anyone who lives above the imaginary line drawn between Atlanta and Los Angeles) don't get enough sun to synthesize Vitamin D, so supplements are necessary. You should get a blood test and aim for vitamin D levels of 30 or above (some say 60 or above). Supplementation should be in the form of an oil based D-3 capsule, vitamin D tablets don't work (remember Vitamin D is fat soluble).

If you are taking vitamin D, consider supplementing with Vitamin K2 (in the form of MK4 or MK7) which helps regulate calcium uptake in your bones and reduce calcium deposit in blood vessels. 100 mg/day.

If diabetes is the concern, consider magnesium supplementation as well.
