What Hacker News says?

  1. Here's another report of toxicity at a similar dose: https://jeffchen.dev/posts/Vitamin-D-And-Heart-Palpitations/ Dr Boone posted on HN, and claimed that vitamin K2 would not counteract high dose vitamin D: https://news.ycombinator.com/item?id=24262492 I am not aware of any randomized controlled trial of vitamin K2 for protection against vitamin D toxicity.
