Guar Gum


Safe substance and/or breastfeeding is the best option.

Natural polysaccharide obtained from the seeds of the leguminous plant cyamopsis tetragonolobus.
Indigestible and unabsorbable, it reduces the intestinal absorption of nutrients (carbohydrates, fats). It has satiating properties and is a mild laxative.
It is a thickener and gelling agent used in the food and pharmaceutical industries. Devoid of toxicity.

Since the last update we have not found published data on its excretion in breast milk.

Its pharmacokinetic data (very high molecular weight and lack of intestinal absorption) make it very unlikely that significant amounts would pass into breast milk, or be absorbed by the infant.

Diet, exercise, and breastfeeding improve blood sugar levels.

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.
