Lepidium meyenii


Safe substance and/or breastfeeding is the best option.

Cruciferous plant cultivated in the Andes (Peru, Bolivia). The root is consumed, rich in proteins and nutrients (nutritional value similar to that of cereals) used secularly in the diet of Andean populations. It contains macaenes and macamides (unsaturated fatty acids and their amides), glucosinolates, imidazole alkaloids, sterols, catechins, and vitamins B, C, E, and K. (, Lock 2016)

It is popularly attributed fertility-enhancing functions that have not been rigorously scientifically proven. (Wang  2019, Valerio 2005) 

It does not affect prolactin levels (Gonzales 2016), nor does it have estrogenic (Powers 2015) or androgenic effects (Bogani 2006). No published adverse effects. (LiverTox 2019, Gonzales 2016, Valerio 2005)

Being a tuber widely used in the diet of Andean populations and devoid of toxicity, its consumption would be compatible with lactation.

Suggestions made at e-lactancia are done by APILAM team of health professionals, and are based on updated scientific publications. It is not intended to replace the relationship you have with your doctor but to compound it. The pharmaceutical industry contraindicates breastfeeding, mistakenly and without scientific reasons, in most of the drug data sheets.

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.
