If you are taking D3 (don't take D2 unless you can't get D3) you should also take K2 as they work synergistically for greater benefits from both.

Agreed. But the max daily dose for D3 is supposedly 10,000iu. I'm concerned that anything more could have adverse effects. I take 5000iu with K2. I also take trace amounts of borax each day.

dose should be to optimize serum levels, which most doctors are testing for these days. 36-48ng/ml is a good range. 2000iu/day gets most adults in this range. but you could also do 5000iu every few days. if you're getting a lot of sun exposure hold off on the pills, your body is making enough. when you're cooped up indoors for the long winter months you likely need a higher dose.

additionally, D3 can be taken in a megadose at the beginning of an infection or virus (100,000iu/day for up to 3 days)

I just bought mk7 with 5000 iu d3 and 200 mcg k2. It says to take one pill every 5 days. Should I just ignore that and take one everyday instead ?
