Zinc Salts

Very Low Risk for breastfeeding

Safe. Compatible.
Not risky for breastfeeding or infant.

Zinc (Zn) is an essential element for nutrition. It is present in many foods.
Recommended daily allowance of Zn is 8 to 15 mg. (Moran Hall 2010). Millions of people worldwide are Zn-deficient.
It is used as a treatment for Wilson's disease and Acrodermatitis Enteropathica.

Zn is involved in the regulation process of lactation (Lee 2016).
Pasteurization of the milk does not affect the concentration of Zn and other trace elements (Mohd Taufek-2016).

The average concentration of Zn in breastmilk is 4 to 16 mg / L (Picciano 1976, Hannan 2005, Dórea 2012) which is independent of plasma levels and maternal daily intake (Krebs 1995, Chierici 1999, Hannan 2009).
Intestinal absorption of zinc is almost doubled during pregnancy and lactation (Fung 1997).
Zinc levels in the infant are dependent on Zinc levels in the breast milk (Dumrongwongsiri 2015)
With a varied and balanced diet, an extra intake of minerals is not needed. Excessive intake of Zinc may cause gastrointestinal problems and Pancytopenia (Irving 2003).


We do not have alternatives for Zinc Salts since it is relatively safe.

Suggestions made at e-lactancia are done by APILAM´s pediatricians and pharmacists, and are based on updated scientific publications.
It is not intended to replace the relationship you have with your doctor but to compound it.

Jose Maria Paricio, Founder & President of APILAM/e-Lactancia

Your contribution is essential for this service to continue to exist. We need the generosity of people like you who believe in the benefits of breastfeeding.

Thank you for helping to protect and promote breastfeeding.
