Careful with this I took vitamin d every day no problem for a year. Randomly started getting heart palpitations one week and was trying to figure out why. Got an Apple Watch to monitor for a fib. Was asking myself what changed in my life that it happened all of a sudden and realized I had started taking K2. ChatGPTs theory is that it really made the absorption of vit d effective and led to hypercalcemia.
Stopped taking vit d and k2 it resolved after a week no problems almost a year later.
It should be the opposite, not taking K2 leads to calcification as K2 helps your body absorb calcium instead of lingering in your circulatory system.
