Breast Yeast Infection and How To Treat It

Breast yeast infection is very hard to diagnose but many women will get this infection while nursing their baby. Usually it is diagnosed as mastitis of the breast first, which is an inflammatory condition caused by bad bacteria. Antibiotics are prescribed for mastitis and if the infection is being caused by yeast, they fail to make a difference. Various medications described in the study referenced below are used after that in an attempt to get it under control.

This condition can be very painful and can be very hard to get rid of, many women are only able to keep it under control until they stop nursing.

How Do You Get It?

When you get internal breast yeast infection it indicates that your good bacterial levels are very low because it is good bacteria that keep yeast under control in the body. The mother also passes along these good bacteria, along with all her antibodies, through her breast milk to the baby and this jump starts the baby's immune system. Most of the time the baby develops a yeast infection as well, usually oral thrush, which is a yeast infection of the mouth.

How Do You Treat Breast Yeast Infections?

In 2011 Louisa Hanna, MD and Stacie A Cruz, MD published a study in the Permanente Journal titled, Candida Mastitis: A Case Report, this study talks about the use of drugs on the nipples and swabbing the inside of the infants mouth with prescription creams for 14 days. If success is not achieved, fluconazole is usually prescribed for two to four weeks. In spite of the prescription drugs and the long length of treatment, the infection often recurs like it did for this woman in the study, in spite of two rounds of Fluconazole and prescription creams. Her symptoms were finally resolved by a change in diet and probiotics.

I do not recommend herbs to treat a breast yeast infection because they can be passed along to the baby in breast milk. However, the above study points out that less than 5% of Fluconazole taken by mothers with a breast yeast infection is actually passed onto the baby through the milk so I doubt any herbs would as well. However, I do not know of any studies that prove this.

If you do decide to take herbs for your breast yeast infection I would avoid anything that contains pau d'arco. There are reports floating around that suggest pau d'arco could cause problems with brain development. I don't know if this information is true but why risk it.

Because breast yeast infection is usually caused by a lack of good bacteria and probiotic bacteria are completely safe, that is the safest way to treat this. Doses quite often need to be very high with 300 billion or more bacteria per day not all that unusual.

Profase is the best yeast killer of the three probiotics listed here. The bacteria amounts are not as high as the other two but that really isn't an issue because of its yeast killing abilities. However, if you combined it with Floraphage its numbers go through the roof. Both work extremely well with Biofase.

Custom Probiotics formulas are made up of good bacterial strains that are normally found in the human body to begin with. They contain beneficial strains of live bacteria in very high doses. Independent testing has verified 78 billion in newly manufactured capsules and its guaranteed to contain 60 billion living bacteria per capsule at the time of expiration, which is 1 year.

The dose for CP-1 should be started at two capsules two times a day for a few days with colostrum. Then raise the dose to four capsules two times a day for a few days. After that, follow the directions on the page to establish your optimal dose.

The 11-Strain probiotic powder is also very good for breast yeast infections. It contains the same 5 strains as CP-1 with an additional 6. One adult scoop contains 200 billion bacteria making it a true probiotic powerhouse. You take it the same way as CP-1 starting at 1 scoop a day and work up as needed.

Symbiotics Colostrum Plus from Amazon is also a good idea because it helps good bacteria to establish themselves in the body. Colostrum Plus contains 1.2 grams of colostrum and lactoferrin and this is what jump-starts the immune systems of babies and helps the good bacteria to grow in their intestine as well. It has been found to be anti-fungal, antiviral, and prevents the growth of bad bacteria and other pathogens in the intestine. It stimulates the immune system by up to 400% and controls cell and tissue damage. It also regulates iron binding and helps heal leaky gut syndrome, which reduces and alleviates allergies. I would take 1 or 2 tablets 3 x a day with the probiotic of your choice.

Biofase is an enzyme product designed to eat yeast and bad bacterial biofilms and the cell wall of yeast. One of the enzymes does enter the blood stream and kills yeasts no matter where it is found. I would start at 1 capsule 2 times a day 1 hour before breakfast and at bedtime. Work up to three capsules or more two times per day if needed.

Most of the time you will have to combine Biofase with one of the Custom Probiotic formulas or Profase to get breast yeast infections under control. They can be taken together or 10 to 15 minutes apart.

Coconut oil from Amazon should be used externally on the nipples and I would take 1 tbls by mouth 2 x a day as well. Coconut oil has been found to explode the nucleus of the candida yeast cell killing it from the inside out. Because it is a food, it is completely safe for your baby. As a matter of fact, the fat is very good for brain development.

If your baby has developed thrush I would combine the colostrum with the probiotic with a little bit of water to make a paste and feed it to them. Not only will this clear up the thrush but it is extremely good for their immune systems.

What should you expect from this breast yeast infection treatment?

The probiotics will begin to clean you out intestinally while it raises good bacterial levels. Your stomach might feel a little uncomfortable for a few days but it will pass. It will then be transported to the breast where it will help crowd out the yeast.

Symbiotics Colostrum Plus will create a cascading effect upon the immune system throughout your body and raise immune function by 400%. This increased activity of the neutrophils and macrophages will help rid you of the yeast in your breast and where ever else the yeast may reside.

Biofase and coconut oil will provide a one two punch to kill the yeast cells from the inside out while helping prevent your baby from getting thrush.

I would also avoid the blatant sugars in your diet. You need some carbs while breast-feeding, but it is much better to get them from fruits and vegetables than processed grain junk foods, sugar and fructose.

You could also combine the two probiotics for breast yeast infection like Reba and Elizabeth did below.

So the 300 billion of probiotic worked. I did that and the doc also found some that a lab made in our town and he told me to try that too, I did. So I think a combo of the two probiotics, both inside and out worked well. Thank you for your suggestion. I will be passing things on to my friends who are new mothers. Thanks a bunch. If I have any other problems I will keep in contact.

Breast Yeast Infection Testimonials

Hello Dan

I have been taking 3 capsules of the CP-1 twice daily (with the colostrum, and also the Biofase) and am having good results, my symptoms disappeared after 2 weeks, and decreased significantly after the first week. I had my milk cultured after 1 week of taking the supplements that you recommend and it came back as having no fungus! I don't know what I would have done if I hadn't found your website. I will definitely be sharing this info with other Mom's out there that are dealing with the same problems.

Thank you so much,

Hi Dan,

I've had great success in fighting thrush/breast yeast infection with your probiotic and biofase combo.  I've also read all of the information on your site and have learned so much about my diet and healthy eating.  Most important of all - I am able to feed my baby pain free with this recipe after trying many different things.  I just placed my first re-order.

Thank you,


I had recently given birth and had been re-admitted to the hospital due to a bacterial infection. I was on IV antibiotics for four days and sent home with oral antibiotics to take for two weeks. The antibiotics completely wiped out my system! I had been nursing my daughter when she developed a yeast infection diaper rash and I realized I had thrush in my milk ducts. I was so distraught with the knowledge that we would just keep passing the yeast back and forth. I had no idea how to combat this besides calling my doctor and taking medication that was NOT guaranteed to completely treat the yeast and keep it from coming back. 

I stumbled upon a forum where another mother had recommend your website and treatment. I found your website and read all of the information on yeast in the milk ducts. The most detailed and informative website on yeast by far! I finally had hope that I could concur the yeast and continue to breastfeed my daughter! I started on your recommended doses of Biofase, Profase & CP-1, along with taking coconut oil and grapefruit seed extract. I also gave my daughter a combination of the Biofase and Symbiotics Colostrum Plus. Both of our symptoms cleared up within two weeks!!

Some people live with passing yeast back and forth while breastfeeding for months! We continue to take the Biofase and probiotics keep our immune system running. Recently my husband caught a cold virus and both my daughter and I stayed virus free. I contribute it to the Biofase and probiotics we continue to take. Also, Biofase keeps me regular and gas free!

I am so thankful I came across your website. I would recommend it to anyone fighting the yeast battle. 

Thank you!


Thanks so much for your follow up! I do really appreciate your advice and products. They've allowed me to continue breastfeeding without the recurrent (and painful) thrush problems I was having!! The doctors I talked to really had nothing to suggest (I can't take prescription antifungals). I know it's your Biofase and Profase, because after a couple months I tried to taper off the products and the thrush returned.

It works!

Breast Yeast Infection Commonly Asked Questions?

How common is breast yeast infection?

It is very common in nursing moms that have recently taken antibiotics or suffer from recurrent vaginal yeast infections. Sometimes though the infections are actually bacterial in nature and not yeast at all.

How long for breast yeast infection to clear up?

This is an impossible question to answer because everyone is different and will have different levels of infection. But with prescription drugs it can take 2 to 8 weeks and natural methods take about the same amount of time.

How long does a breast yeast infection last?

It varies from person to person, we are all different and women can have this to different degrees. The worse it is the longer it will take to get rid of it. In extreme cases all you might be able to do is keep it at bay until you stop breastfeeding.

What causes fungus under breasts?

Usually candida yeast, especially candida parapsilosis because it commonly lives on the skin. Under the breast can be a warm and moist environment and this can allow it to develop and get out of control. Usually a rash develops first and in late stages the skin forms blisters, cracks and weeps fluid.
