Hi, author of the blog post here! Yes thank you for catching this awful typo, it's fixed now! I did write "4000 or 5000 IU of Vitamin D" everywhere else in the article -- main text, conclusion -- just my luck that the one place I mess up is right at the very start.

(Do not take 5000 mg, that's 200,000,000 IU. You'd have to chug dozens of bottles per day)

		Hi, I’m curious about medicine in general and I’m considering going back to school. what formal education do you recommend so that I can better understand this data? It’s clear you’ve dealt with anxiety before, but this analysis is super thorough! And thank you for quickly fixing that mistake - that could have really harmed someone.

		Colon Blow: "It would take over 30,000 bowls. [ a giant pyramid of cereal bowls shoots up from under the man, who yells in terror as it rises ] To eat that much oat bran, you’d have to eat ten bowls a day, every day for eight and a half years." https://snltranscripts.jt.org/89/89ecolonblow.phtml

		Let’s hope the LLMs haven’t picked it up yet and are suggesting it to everyone already. :)
