This question requires multiple answers.
Glutathione is an extremely important molecule in the body. It is necessary for over thirty processes in the body. This includes being the master antioxidant, master detoxification agent and is necessary to buld the immune system. It helps protect every cell, and even help repair damaged DNA.
First, glutathione itself is poorly absorbed by the body. If you are taking an over-the-counter supplement of glutathione, you are probably not getting any benefits. So it doesn't make sense to take it whether you are breastfeeding or not.
Glutathione is produced by every cell of the body, assuming you have proper nutrition to provide the necessary precursors for glutathione. These precursors are glutamate, glycine, and cysteine. Our diets are typically rich in glutamate and glycine, but not cysteine. Unfortunately, cooked and processed foods, and foods grown in nutrient leached soils, are typically deficient in useable cysteine.
You need bioavailable cysteine to allow your cells to manufacture their own glutathione. Unfortunately, cysteine found as a supplement is typically not properly absorbed either. For example, milk has a very high concentration of what is called bonded cysteine. Drinking raw milk is a good source of bioavailable bonded cysteine. However, when it is pastuerized, the bonded cysteine is broken down, and no longer can be properly absorbed into the body to function in making glutathione.
Nature knew what it was doing when it designed milk, and for humans, breast milk. Babies need glutathione to build their immune system. Human milk has one of the highest concentrations of all nutrients necessary to make glutathione. However, heating or storing it will also diminish the ability for it to build glutathione in the baby. An infant, or even adult, that has insufficient glutathione will have a compromised immune system.
There are many foods and one naturally safe supplement that I know of that can provide necessary precursors for gluathione. I have a booklet on glutathione, its benefits and how to build it that goes into much more detail. I can send it to anyone that is seriously interested. You can contact me at

So to answer your question: Most supplements are typically not safe, nor are they effective, in building glutathione. However, there are safe and effective ways to allow your body to buld glutathione, even for infants and pregnant women.
