Generally, it's recommended to take your Vit D in the morning as it can keep some people awake.

Mine is in drop form, so I have 2-3 drops on a spoon first thing in the morning, followed by a little "cocktail" of magnesium chloride with 1mg of taurine = 1 pill (the latter helps magnesium to be absorbed better, amongst other things), plus another pill of B complex, which apparently is also necessary for magnesium uptake. My calcium I get via food. Oh, and if I remember, I also take a tablet of probiotics first thing, too. They can help your stomach to absorb all nutrients better, but apparently particularly help with the absorption of taurine.

After taking vitamin D3 for one year, my levels have reached 61ng/ml.

No colds, and generally feel fine!!!
