Thanks for posting. This caught my eye: “Excessive vitamin D intake can be harmful and has been linked to increased risks of falls and fractures among older adults.”
I’ve been taking 5,000 IU/Day since March 2020 (pandemic start). My Vit D blood level has been ranging 46 - 60.
We take 4,000 iu daily with K2 for the past 15 years plus a boatload of other supplements. We are pretty healthy.
