All I've heard is the danger of calcium precipitating out of your blood and causing arterial blockages. Apparently D3 potentiates this so that the concentration

  with the way research is going i'd expect to find it's something else in conjunction with D3 that causes that, and not merely D3. like D3 and a high sodium diet, or D3 and <some local thing>. as mentioned though, i only think that 500-1000iu is not enough for most people. I'm not a doctor though, but it is one avenue of alleviating SAD as well as lethargy and stuff that most people vape/smoke/caffeinate to deal with.

  You should take D3 with vitamin K2 (talk with your doctor first if you're on blood-thinning medications) to avoid calcium being dumped into soft tissues (K2 ensures it preferentially goes into bones). It's a good idea to get your vitamin D status tested yearly and aim to be at least 50 ng/ml (120 nmol/l), but not more than 80 ng/ml (200 nmol/l). As an example for dosages: I take about 7000 IU of vitamin D3 and 180 mcg of vitamin K2 daily. My levels test at about 180 nmol/l and my blood calcium is normal.

    How did you determine that ratio of D3 to K2?
