YouTube - Vitamin D and Diabetes-Can We Prevent it?
The simple way to ensure you are getting sufficient vitamin d3 from supplements or from sunshine (diet can at best only supply 10% of our 5000iu/daily need) is to regularly get 25(OH)D tested.
Grassrootshealth D Action
are a charity promoting vitamin D awareness and as part of a study trying to be more precise about what Vitamin D status is associated with least disease incidence are trying to follow the 25(OH)D status of 10,000 volunteers and their need for hospital treatment.
As part of this trial you can get 25(OH)D tested by post at cost price ($40). Currently it looks like 40~60ng/ml is going to be associated with least chronic illness, with the smart money going on 55ng/ml as overall the best for both physical muscular performance and with human breast milk flowing replete with D3 the best level for pregnant and nursing mothers.
If you search the online vitamin suppliers you should be able to find a 5000iu/d/D3 in an olive oil based capsule for around $15 for 360 so it's not an expensive business to lower your heart disease, cancer and diabetes risk level.
