I am one of those blonde (now grey) blue eyed people who are allergic to sunlight. It is manageable and since a teenager I have coped . When I was over 60 I was given Vitamin D in the winter and since being diagnosed with Osteoporosis I have had it all year round in a monthly dose of 80,000 UZ2ml ampule. I suddenly got a very high Vit D blood test and have been pulled off the supplement. I have to return to the doctor in a month with a new set of blood tests. Excess Vitamin D can cause severe side effects. If you are taking Vitamin D, have a good diet and going out in the sun etc, you need regular blood tests to ensure you are not overdoing it. I knew that if you were over 65 you should not take additional Vitamin B12.
I am still on Vitamin D3 with Calcium which is totally different. I also take vitamin K2.

I had no side effects. Doctor acted quickly and the nurse is coming tomorrow to take my annual blood tests. It was a routine test and she picked up the high level of Vit D in the results. I am in France and it is normal for nurses to do blood tests and not doctors (frees doctors up to see patients). We are covered by 3 district nurses, two female and one male. Our clinic that does the blood tests is 20 mins away and they are open every working day in the morning. Doc was saving me the trip.
Blanket supplementation of vit D to everyone with osteoporosis can be downright dangerous. As someone with sarcoidosis, I had to say a very firm no when someone who should have known better suggested 20,000 units for me. Even 400 units makes my heart irregular! Note that the normally measured 25D does not necessarily provide an accurate picture of vitamin D circulating in the body. This can only truly be established by measuring 1.25D. If 25D is high then 1.25D is likely to be high, but for someone with sarcoidosis and some other medical conditions, it is possible to have extremely low 25D but perfectly fine or high 1.25D. And it is the 1.25D that matters. Too high a vit D level is as bad for the bones as one that is too low.
There are blood tests for Vitamin D and D3 (totally different). Your levels should be normal before treatment is started and annually. If there are reasons why you can’t take them, just tell your doctor. It was suggested I take Tramadol, I took out the report I always carry to prove I was allergic to it and it nearly killed me. My specialist had never heard of the specific symptoms of SSRI syndrome which is extremely rare to put it mildly. Always ask for tests before you take anything you are unsure of. Just had my annual blood test report and I take it to my doctor otherwise she can’t access it.
1.25D is the test for D3 so you are talking about the same two tests as me. In anyone with sarcoidosis, the body may turn 25D into 1.25D much more rapidly than normal. This means that there is generally very little 25D left and it has to be 1.25D that is monitored before and during treatment. My 1.25D has always been fine, thank you! (The only reason 25D is measured at all is the test is cheap and easy and gives an indication of overall vitamin D status in healthy people. 1.25D is far more costly and the results involve waiting for a few weeks.)
