Vitamin D is mostly produced from biological sources, and biological production would be required for Mars. A 15 minutes exposure to ultraviolet lighting, 3 times a week, should be sufficient to produce the required vitamin D for humans. A tolerable intake is about 20-50 ug/day. So less than 0,5g per year. The entire yearly supply for a 1000 person settlement would be 0,05 kg.

			==Vitamin K==
			[[w:Vitamin_K\|Vitamin K]] is a group of structurally similar, fat-soluble vitamins that the human body requires for complete synthesis of certain proteins that are prerequisites for blood coagulation (K from ''Koagulation'', German for "coagulation") and which the body also needs for controlling binding of calcium in bones and other tissues.

			Recommended consumption is 90-120 ug/day, or about 0,1 grams per year. The entire yearly supply for a 1000 person settlement would be 0,1 kg.
