P.S. If you happen to get the NARCOMS newsletter called NARCOMS Now, I just received an issue of it (volume 8, #4, 2019), and there is a short article on pages 12-13, "Should People with MS Take Vitamin D? How Much and How Often?" Its information is from a paper presented at the ECTRIMS conference in September 2019, and it pretty much answers one of my questions about vitamin D--how much of it is too much?
Quote:
How much vitamin D should a person with
MS be taking to maintain health? Dr. Ascherio
said he advocates a dose of 3,000 IU vitamin
D per day. Dr. Mowry usually treats patients
with MS who have low serum vitamin D
levels to reach a target blood level of 40 to
60 nnmol/L. To achieve this, she suggests
oral daily supplementation at doses ranging
between 2,000 and 5,000 IU. Higher doses are
not recommended due to risk of toxicity.

Dr. Alberto Ascherio is affiliated with Harvard University's T. H. Chan School of Public Health. Dr. Ellen Mowry is a neurologist at Johns Hopkins University School of Medicine.
I take this to mean that 5,000IU/day is regarded as the maximum dose.
