taking vitamin D twice a day , is more efficient than one dose
-
on rpf haidut says taking 2-3000iu twice a day will probably raise levels the same as taking 8-10,000 iu once per day

I take 3000iu in the morning then another 2000iu later in the day, with meals. should I add a third dose of 2000iu? it's winter here.

Are you getting enough K2 from egg, milk, butter and cheese (Gouda, brie)? Probably not. So, I won't take more than 2000 UI vit D without supplementing. Interaction between liposoluble vitamins. I can develop if interested.
How much was the last blood test for Vit D? if between 35 - 45 ng/mL, no need to take more than 2000 UI.
I take 5000 UI during winter time. (November - May). 2 x 5000 UI the first three days when attacked by flu. -
