Who Needs Vitamin A?
children, particularly those with darker skin, and the elderly, especially those on poor diets who may also be house bound, require ample supplies of this vitamin. People who are veiled or robed because of cultural or religious reasons will naturally absorb less vitamin D from sunlight and should therefore have supplementation. Babies may need a vitamin D supplement, which is usually given with vitamin; the dosage must be followed carefully because excessive doses of vitamin D are toxic. Pregnant and breast-feeding women should increase their intake, and convalescents, vegetarians and vegans whose diets lack fish and dairy produce should ensure they get adequate supplies. People who live in cities, where pollution may filter the sunlight, should increase their intake of vitamin D, as should night workers, whose exposure sunlight is necessarily very limited. Taken with vitamin A and C, vitamin D can play a part in preventing colds, so if you are prone to these you should take supplement
