Did you take vitamin K? You really need that to process vitamin D. This LessWrong post goes into more detail. Quotes from the article:
Atli Arnarson makes the case in Is Vitamin D Harmful Without Vitamin K? that Vitamin D toxicity at high doses is usually about K2 deficiency because both are needed in the same pathways and more K2 is needed when there’s more Vitamin D. Vitamin D toxicity leads to hypercalcemia where there’s too much Calcium in the blood. Calcifediol moves some calcium from the bone to the blood and K2 is needed to put the calcium in the bones. Hypercalcemia is bad because it lead to blood vessel calcification. Observational studies link low Vitamin K2 levels to blood vessel calcification with K2 being more important than K1.
This is amazing. I’ve often used blocking extensions, only to remove them when I “needed” them—e.g., a google search about a health question resulted in an informative reddit thread. This is great, because now I can use these sites when I have a legitimate need (or at least when it’s worth a 30 second delay). It’s great for email in particular, because I use it both out of need and as a distraction.
