Again: those are medical doses, given either very temporarily or in weekly/monthly doses.
2k definitely ha san effect on a daily basis. To really know, there are two things you can do:
1. Get a vitamin d test. Fairly cheap online
2. Use the dminder app to track estimated D over time from supplements and sun exposure
I don’t think I was clear enough in my post: 60,000 is not a daily dose! Higher than 4000 IU daily over a long period can lead to excess, according to Deva Boone, a doctor who was posting here and wrote some articles on this topic.
60,000 is something I’ve read about where 1. A doctor wants to correct a large deficiency, and 2. Judges large, infrequent doses are best. (My guess would be for adherence)
Do not, do not. Do not take anything anywhere in that range on your own. Stick to sub 4,000 for a daily doses, and ideally get a blood test.
The amount used as an interventional or short term treatment can greatly exceed what is a prudent amount to take daily. Taking 50k/day long term is probably a bad idea.
