Yes, I didn't go exactly that route but I started taking "high" dosages. I get blood work done every 6 months and you can see from the picture below that I was at 43. During that time I was taking 5,000iu/day.

I then started taking 30,000iu/day and my levels jumped up to 102 and then 120. My cardiologist said he wanted it below 100 so I dropped down to 20,000iu/day. Now it fluctuates between 90 and 100.
I read several books regarding Vitamin D megadosing (this was also when Covid was going on so higher levels of Vitamin D were being recognized as a good defense) but the book below had the biggest impact on me because the author is also a doctor and recommends 30,000iu/day.

If you search my posts on here you will see one where I talk about Magnesium supplementation and why I recommend that everyone take it because it has so many positive benefits for your body and the typical American diet struggles to get enough.
You may also want to consider supplementing with Vitamin K2 (MK7 form) because it's job is to put calcium in your bones and not let it get stuck in your blood. If you have higher levels of vitamin D then you can run the risk of having more calcium in your blood which is why you want Vitamin K2 to ensure it is deposing the calcium from your blood into your bones.
