Potassium Gluconate

Very Low Risk

Safe. Compatible. Minimal risk for breastfeeding and infant.

Unprocessed plant foods such as legumes, nuts, vegetables and fruits are very rich in potassium.
A dietary intake of potassium of about 3,500 mg (90 mmol) per day is recommended (WHO 2013, WHO 2012, Hall 2010).
Potassium gluconate is used in medicine, like potassium chloride, to correct, orally or intravenously, potassium deficiency (hypokalemia).
Also used (E577) as a stabilizer and acidity regulator in various foods.

Potassium is an ion present in breast milk at a concentration 3 to 7 times greater than that of plasma: ≈ 14 - 18 mEq/L (Lawrence 2016, Allen 1991).
Like other monovalent ions, it enters and leaves the milk freely, inversely to the lactose concentration (Lawrence 2016 p119).
Potassium supplements do not significantly change levels in breast milk (Hale, Ereman 1987).
In the body, it is found mainly within cells, with a plasma concentration within precise limits (3.5 to 5.5 mEq/L), outside of which there are serious clinical alterations.
Potassium treatments cannot raise the concentration in milk without first altering that of the blood.

At therapeutic doses, potassium chloride is compatible with lactation (Hale, Briggs 2015).
WHO Essential Medicines List: compatible with breastfeeding (WHO 2002)
