Hello and welcome to the forum. We do always recommend working with your doctor and it would be good to run your query by them as well. While this is above what is listed as the maximum dose, it generally is accepted that toxicity from too much vitamin D is rare and difficult to achieve. Up to 10,000 a day does not produce side effects for most. Please speak to your doctor about your concerns though. https://www.healthline.com/nutrition/vitamin-d-dosage#section2
Hello~I would discuss this with the prescribing physician, but, that being said, I have been taking that same amount of "D" daily for years and have had no side effects. According to blood work, I am very low in this nutrient, sadly, since I have been over here in New Zealand, they do not check for those levels, so, I just take that amount every-other-day and so far, no issues..
I agree with the above posts. It depends on the person. You don't want the level of Vitamin D to get too high but I take 6,000 IU per day to stay in the normal range . I had mine checked several times about once a year and it is staying at the right level for me now. So you should follow up with the doctor to get a blood test in a few months.
