When I was exclusively pumping, a friend recommended blessed thistle to me as a way that I could increase my milk supply. I had never heard of it before and was wondering – what is it, exactly? Does it really work, and if so, how much should I take? Here’s what I learned, and everything you need to know about blessed thistle and increasing milk supply.

What is blessed thistle?
Blessed thistle is a plant that is native to the Mediterranean and Southeast Asia, and now grows in Central Europe and the Southern United States. It grows as a weed, and traditionally been used in different cultures as an herbal remedy to treat digestive issues and stimulate appetite.
Blessed thistle is also thought to be helpful in reducing the likelihood of post-partum hemorrhage, increasing milk supply, and having antidepressant effects.
How does blessed thistle increase milk supply?
One theory is that it is a galactogue that works by stimulating blood flow to the mammary glands.
A galactogue is a substance that increases milk supply, though how it works exactly is often not known. Some galactogues are foods (for example, oatmeal), while others are herbs (such as fenugreek) or medication (domperidone). Other examples of galactogues include brewer’s yeast, fennel, goat’s rue, and raspberry leaf.
Is it effective at increasing milk supply?
Unfortunately, there haven’t been any clinical trials of the effectiveness of blessed thistle as a galactogue. One study did a review of mothers that used it, and their outcomes. There were a few limitations to this the study, though – there were only three participants, and all of them used both blessed thistle AND fenugreek, making it difficult to isolate the effects from each of the two herbs.
Of the three participants using the combination of blessed thistle and fenugreek, two found the combination effective and one was unable to judge. The time frame that the participants took to see results was between two hours and two days.
More anecdotally, Dr. Jack Newman, a breastfeeding expert who has written extensively about medications and breast milk, says that in his clinical experience, fenugreek and blessed thistle taken together “seem to increase the milk supply.”
Therefore, we don’t know for sure, but there are some indications that it may be effective in increasing milk supply.
Is it safe for anyone to use?
Another traditional use for this herb has been to stimulate menstruation or act as an abortifacient. As a result, if you’re trying to boost your supply during pregnancy, it’s probably not a good idea to use blessed thistle, especially without talking to your doctor.
When you buy products containing it, the label may say that it’s not safe for breastfeeding mothers. Dr. Newman states:
There are some preparations of [fenugreek and blessed thistle] that are labeled “not for use by nursing mothers”. Don’t worry about this; these herbs are safe for the mother to take because so little gets into the milk.
What is the recommended dosage of blessed thistle?
In the study, participants used very different dosages, ranging from 600mg per day to 3,000mg.
Dr. Newman recommends the following dosages:
- Fenugreek – 3 capsules, 3 times per day
- Blessed Thistle – 3 capsules, 3 times per day
Unfortunately, he does not specify what dosage of capsules he’s referring to. Most fenugreek capsules are 610mg; blessed thistle seems to come in both 390mg and 780mg doses. To be safe, I would assume he means the 390mg dose; nine capsules of 390mg is about 3,420mg per day, which is close to the maximum used in the study.
Blessed thistle is also often an ingredient in nursing teas, though the amount of the herb is much lower – meaning that you would need to drink quite a bit of tea to get the same result that you might see from the capsules.
What’s the bottom line?
If you’re trying to increase your milk supply and are not pregnant, blessed thistle may be worth a try! You’ll probably have the best results if you take it in combination with fenugreek.
One option is to take individual capsules of fenugreek and blessed thistle as described above by Dr. Newman; however, combination capsules with higher dosages can be a good alternative and usually require taking fewer pills.

Can anyone tell me a name of a combo pill to buy?
Here’s one:

I began taking a high-dose fenugreek-blessed thistle combo supplement made for lactating moms after my supply tanked when I started my menses back at about 8 months postpartum. I had noticed a steady decrease in my supply starting around 6 months when my son started solids (exclusive breastmilk prior) & sleeping through the night (would nurse on/off throughout night prior). For the first 6 months I had tons of breast milk. I tried drinking lots of water, getting lots of sleep & drank raspberry leaf tea daily, but to no avail. Initially, I didn’t think the supplement was helping and then after 1 full week of taking the max dose, bam! My supply is much better.
So glad to hear it, Ashlee!
I had a definite increase with last LO when I took Healthy nursing tea! I don’t need it this time! I also see an increase with eating oatmeal for breakfast every morning!
I just ordered a bottle of blessed thistle! I’ve tried fenugreek in the past and both me and my little girl had terrible gas even on low doses. I’ll see if the thistle will help on its own. I’ve been trying fennel too, which has really helped with my slow letdown.
Thank you for sharing this post. I have taken blessed thistle and fenugreek together. This is my third baby and my second time exclusively pumping. First baby was formula fed (didn’t know about exclusive pumping) and I was never able to nurse any of my children.
I have used the combination of blessed thistle and fenugreek both times.
So the first time I used it with my second child it was around 2 months post partum. I definitely saw an increase in my supply. However it made me very sick. It inflamed my intestinal tract and I let it go for several weeks until I had to go to the hospital. I didn’t want to stop taking it because it was helping my supply so much. I ended up stopping it and taking a strong over the counter probiotic called VSL#3. Cured me in two days. It was amazing. However I decided not to keep taking the combination BT and Fenugreek. Supply did drop but I still pumped for several months after that. 10.5 months in all for my second baby. There was a point that I tried to take the combo again and it did nothing for me. It didn’t upset my stomach and it didn’t but increase my supply. I found that interesting. Maybe my supply was established to the point of not changing.
Third baby came along and when I realized I was going to have to exclusively pump again I decided to try other herbs first. I tried all kinds of things. Goats rue and some sort of root, brewer’s yeast, beer, you name it and I probably did it. Nothing worked for me. Then I decided to give blessed thistle and fenugreek a try again. I was about two months post partum again. I decided to take a brand that was made for nursing mothers which was more expensive but worth it if I didn’t get sick. Well I did start to get sick and at the immediately feeling of an upset stomach I took the probiotic. It worked. My supply was up and no upset stomach. I only had to take the probiotic twice.
So bottom line I think herbs work different on everyone. What works for one may not work for the other. But in my experience if you take blessed thistle and fenugreek you might want to take a strong probiotic as well. Good for you and baby anyway.
Good luck Mommas!!
P.S. right now I and 3.5 months post partum. I pump 5 times a day (40 minutes each time, I know that’s too long but it’s what I have to do) with an average of 34oz a day. I only take the blessed thistle and fenugreek combo and drink lots of water. I try my best to stay on a good schedule because I find that helps too but with three kids, I do what I can.
