Zinc is needed for several physiological reactions (together with magnesium). Zinc isn't stored in the body like fat-soluble vitamins, so we require a steady supply from food.

Zinc may be a global problem. Researchers estimate that a considerable percentage of the world's population has mild zinc deficiency.

Preconception, pregnancy, and lactation require zinc. It supports full-term pregnancy and reduces pre-term labour in some women, however experts don't fully understand how.

Like many things in life, more is not necessarily better. Zinc is needed in specific amounts and either extreme (too much or too little) can be harmful.

Obtaining nutrients from food is important and even the best supplement can’t take the place of a nutrient-dense diet (though some people do find the need to supplement with certain nutrients in cases of deficiency).

Exactly. Before making a decision, consult a certified practitioner, doctor, or midwife.

Total zinc in supplements may not reflect bioavailable elemental zinc (which is what the RDA refers to). Every form of zinc can have a varying amount of elemental zinc, according to Dr. Mercola.

As I said, I took supplemental zinc after consulting with a doctor and I recommend you check with your doctor for the right approach for your family.
