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 ...

Zinc is a vital micronutrient that plays a crucial role in enzymatic catabolism, immune cell function, DNA synthesis, and various micronutrient metabolisms. In the elderly, low serum zinc levels have been reported, which weakens the immune system, making them more susceptible to infections and increasing their risk of morbidity.
In 1912 Polish-born biochemist Casimir Funk, working in London, isolated the same complex of micronutrients and proposed the complex be named "vitamine". [34] It was later to be known as vitamin B 3 (niacin), though he described it as "anti-beri-beri-factor" (which would today be called thiamine or vitamin B 1). Funk proposed the hypothesis ...

In 1992, 159 countries pledged at the FAO/WHO ...
