The only vitamin that a diet based exclusively on plants cannot adequately provide is vitamin B12 (see FAQ on vitamin B12 supplementation). Moreover, the use of iodised salt is strongly recommended in plant-based diets (see FAQ on Iodine). Omega-3 supplementation is also strongly recommended during pregnancy and infancy when following a plant-based diet (see FAQ on Omega-3). People with limited access to sunlight might need vitamin D supplements (regardless of their dietary pattern).
The recommended intake of all the other minerals and nutrients can be met by eating a well-planned whole food plant-based diet. Pregnant and breastfeeding should pay attention to some critical nutrients and supplementation is usually recommended. It is always best to check with your healthcare provider before taking any supplement, particularly during pregnancy, breastfeeding and in children.
