Many nursing mothers question the safety of dietary supplements while breast-feeding. Quercetin, a flavonoid commonly found in fruits, vegetables and flowers, has anti-inflammatory properties that help protect the body against free radicals. Although quercetin in produce and grains is safe to consume by nursing mothers, supplemental quercetin may be unsafe during breast-feeding. Consult your health care provider before taking quercetin if you are nursing a baby.
Identification
Quercetin, found in the bark of a variety of plants, is a common flavonoid that plays a role in pigmentation. Although plants containing quercetin have been used for medicinal purposes for several centuries, the flavonoid's abilities were not discovered until several decades ago. Quercetin acts as an antioxidant and may prevent the growth of certain types of cancer cells. Naturally present in a variety of healthy foods, such as onions, citrus fruits, parsley and berries, quercetin is also available as a dietary supplement at most health food stores.
Potential Benefits
The antioxidant properties of quercetin may help reduce the risk of hypertension, certain cancers and heart disease. According to research published in a 2007 issue of the "Journal of Nutrition," supplemental quercetin plays a role in reducing blood pressure levels in subjects with hypertension. Quercetin reportedly acts as an antihistamine and may reduce or prevent allergy symptoms such as watery eyes, runny nose, facial swelling or rash. More scientific research on human subjects is needed to determine the effects of quercetin supplements on allergy symptoms. Consult your physician before using quercetin supplements to reduce allergy symptoms while breast-feeding.
Possible Side Effects
Mild side effects may occur as a result of taking quercetin supplements. These side effects include upset stomach, tingling in the feet or hands and headache. The supplement may also cause severe side effects including an allergic reaction or kidney problems. Seek immediate medical attention if you or your nursing infant experience symptoms of an allergic reaction. These symptoms include facial swelling, throat closure and difficulty breathing. As of publication, effects of quercetin supplements on milk production or newborn development are unknown.
Warning
Although dietary quercetin is safe to consume while breast-feeding, more scientific research is needed to validate the safety and efficacy of supplemental quercetin while nursing. The University of Maryland Medical Center recommends avoiding quercetin supplements while breast-feeding. Always consult your physician before using quercetin or other supplements while nursing.
