Someone following a vegan lifestyle should be concerned
about the possibility of developing what vitamin deficiencies?
Vitamin B12 deficiency is a danger for vegans because the
only significant natural sources of this vitamin are animal
derived foods. Vegans must obtain vitamin B12 from fortified
foods or supplements. Similarly, pre-formed vitamin A and
vitamin D are found predominantly in animal products.
However, vitamin A should not really be a concern because
carotenoid consumption should increase in a vegan diet and
some carotenoids can be converted to vitamin A in the body.
Vitamin D may not be a concern either if the individual has
adequate sunlight exposure for skin synthesis.
