Breastfeeding & Chlorella

Breast-feeding provides your baby with the proper nutrients and boosts her immunity. The exact composition of breast milk changes with each feeding to adapt to your individual baby's needs. Chlorella is a supplement made from Chlorella pyrenoidosa, a microscopic plant that contains high concentrations of chlorophyll. Labels on supplements suggest that they should not be taken during pregnancy or breast-feeding, but new studies suggest differently.

What Is Chlorella?

Chlorella is a single-cell algae that grows wild in ponds and rivers in East Asia. The algae is gathered, dried and made into supplements. It provides nine different essential amino acids, minerals, vitamins and more protein than spinach, rice and soy beans. Chlorella has been used to improve metabolic syndrome, cardiovascular disease, diabetes, blood pressure abnormalities and body fat. It helps the body to remove toxins and improve the digestion. In Britain, some doctors are using it to boost the immune system.

Japanese Study

A study in Japan followed 35 breast-feeding mothers 1. Eighteen of them took chlorella supplements and were compared to the rest. Breast milk from mothers who supplemented with chlorella had higher concentrations of Immunoglobulin A (IgA), which is an antibody. These antibodies help prevent viruses, bacteria and fungus from creating infections. IgA, in particular, helps protect the surfaces of the body that are exposed to foreign substances like the nose, digestive tract, eyes, ears, saliva and tears. This is a big advantage to young babies.


The Japanese study showed that dioxins, a toxin that is prevalent in all modern human environments, is excreted to the baby through breast milk. The mother absorbs the toxin from her environment through her skin, respirations and diet. Chlorella supplementation actually decreased the dioxin amounts in the breast milk, making the milk safer for babies.


According to Hilary Jacobson, in her book, "Mother Food for Breastfeeding Mothers," chlorella can also help remove any mercury deposits in the body. Mercury can come from eating certain fish known to contain mercury, such as tuna, or from amalgam dental fillings as well as other environmental sources. Mercury is a heavy metal that destroys the nervous system over time. Dr. Dietrich Klinghardt, a recognized expert on heavy metal toxicity, suggests chlorella may help rid the body of mercury 3. He suggests that if a mother cannot tolerate the chlorella, sauerkraut may be substituted to bind the mercury in her intestines.


All sources warn that full detoxification of the body should not be undertaken during pregnancy or breast-feeding. When taking chlorella, women should follow the advice of a medical or nutritional professional so they don't ingest too much and trigger a major detox.
