. My OP doctor has all her "ladies" on a Vit D supplement, 800-1000 of D3, and she likes to see a level above 30. In the same breath if you are taking 4 or 5,000 of D, she will cut back on that, with the caveat if you are very obese, you do need a higher dose. She is not a fan of any other supplements, even calcium! it's OK to take a dose like 600, but over 1500 there are two meta-analyses showing the calcium correlated with increased CV events. I’m with her on the calcium, until recently hadn’t watched how much I get in food and, only now, top up the difference.

Dr JoAnn Manson's work was featured in a Harvard Health article back in 2019, which I ignored at the time. https://www.health.harvard.edu/stay...-bones-not-help

This new advice is different from my GP, oncologist and the REMS doctor I saw Wednesday. That office took a new blood draw for Vit D. Last April mine was 73.
