"The non-financial costs such as side effects or potential adverse effects are practically non-existent as well."

This not accurate. I remember that there was an article on the front page of Hacker News an article that explain that Vitamin D is actually a hormone and telling the story of woman that had been prescribed high level of supplementation that could not talk anymore. It had something to do with her calcium intake regulated by that hormone. Luckily she was so distressed she stopped taking the supplementation but still it took her six months to get back to to talking normally and a normal hormone concentration level.

I assume they were talking about supplementation at normal supplementation levels, not 10x - 100x that.

As someone pointed out below, if you drink 10x-100x the recommended amount of water, you're likely to have adverse effects (almost certainly including death at 100x) too.

This case, I think: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3313753/

It looks like she was getting 600,000 IU injections every week for three months. That's 85,714 IU per day. The NHS recommends maintenance does of 400 IU per day, others recommend up to 2000 IU.
