Venn diagram of co-existing micronutrient deficiencies in a pregnant women, and b lactating women. Legend: In both pregnancy and lactation, ovals drawn with a continuous line represent women with folic acid < 10 nmol/L, ovals with large-dashed lines represent women with vitamin B₁₂ < 150 pmol/L, medium-dashed lines circumscribe women with vitamin A < 1.05 μmol/L and dots denote women with vitamin D < 50 nmol/L. Only 3% of pregnant and 9% of lactating women had adequate vitamin concentrations
