Finally, but critically, stay boosted with supplementation as needed. When daily sunlight is not available, you will need a vitamin D₃ supplement. (D₃, aka cholecalciferol, is the type of vitamin D your body produces in response to sun exposure, while D₂, aka ergocalciferol, is a synthetic form—avoid it.) Look for a D₃ supplement that is combined with vitamin K₂, and take it with a meal that includes some healthy fat because vitamin D is fat-soluble and requires some fat to be absorbed.
