Of course, there was a recent article (posted on FR, but I don’t have the link) about a study showing high levels of Vit. D caused calcium deposits in the arteries, leading to heart disease. Who knows what to do with all the conflicting scientific studies?
For myself, I take 400 IU daily & I try to get a little sun each day (when there is any!)
I read that too, and looked into it. If you take the D3 with K2 ( some are sold that way, but you can buy K2 seperately) it’s supposed to minimize that. K2 keeps the arteries soft and supple, according to claims anyway.
