Some people should not take Vitamin D
There are some rare conditions which can make you hypersensitive to vitamin D
- primary hyperparathyroidism
- granulomatous diseases
- some cancers.
If you have one of these conditions you will be under a doctor’s care and should only take vitamin D if it is prescribed for you.
But even if you have one of these conditions, do raise the subject of your vitamin D status with your doctor. Some patients can benefit greatly by having their vitamin D levels optimized, especially those with cancer.
In all these conditions, caution is required to ensure that hypercalcemia (high blood calcium level) does not occur when supplementing vitamin D. Your doctor will know how to monitor this.
For more information, see vitamin D hypersensitivity.
If you suffer from kidney disease you also need to be careful about taking vitamin D, because of the danger of kidney stones.
Actually you don’t need to remember these specific conditions, because there is only one general rule to remember
Don’t take vitamin D if you are being treated for any condition by your doctor, without consulting her first.
The reason for this is that vitamin D is a powerful hormone with far-reaching effects in the body. It can affect medications, treatment plans and dosages.
Lastly, if you think that your 25-hydroxy-vitamin D level is already be higher than 65 ng/ml (the top end of our optimum range) then you shouldn’t be taking vitamin D until you find out for sure!
Everyone else can take vitamin D, including pregnant women and breastfeeding mums. (The sun naturally shines on all of us, doesn’t it?)
