Micronutrient deficiencies are considered a public health problem worldwide. For over 30 years it has been estimated that more than two billion people of all ages are affected by this burden, [1] while a recently published study based on individual-level biomarker data estimated that there are 372 million children aged 5 years and younger, and 1.2 billion non-pregnant women of reproductive age ...

Low calcium and phosphate may give a clue toward osteomalacia from low vitamin D. [12] Specific vitamins like vitamin D or micronutrient like zinc levels can be checked. Fat soluble vitamins (A, D, E and K) are affected in fat malabsorption. Prolonged prothrombin time can be caused by vitamin K deficiency. [citation needed] Serological studies.
Well-researched human vitamin deficiencies involve thiamine (beriberi), niacin , [32] vitamin C (scurvy), folate (neural tube defects) and vitamin D (rickets). [8] In much of the developed world these deficiencies are rare due to an adequate supply of food and the addition of vitamins to common foods. [ 20 ]
