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.
I don’t. Now that we have more visibility, people who know more, please say more.
This would potentially explain the disagreement—if taking lots of D requires K2 but no one’s testing with K2 then all the huge correlations would be there but the interventions wouldn’t work.
