Morning, with a fat-containing meal

Take vitamin D3 and K2 with your largest fat-containing meal, usually in the morning.

Vitamins D3 and K2 are fat-soluble, so a meal containing fat dramatically improves how much you absorb. Many people take vitamin D earlier in the day because, for some, taking it late can interfere with sleep.
