Does Oat Milk Increase Milk Supply?

Yes, oat milk can increase your milk supply. This is because it contains a good amount of useful nutrients as it is derived from oats. Many lactation experts recommend oat milk to increase milk supply.

A lot of moms have battled with reduced milk supply. I am one of those moms that have constantly had to deal with a drastic or insufficient supply of breast milk.

So, I started researching ways to increase my milk supply. I found that oatmeal does this job perfectly, then I got tired of consuming one texture so I shifted to its milk.

There’s no scientific back up so, does oat milk increase milk supply?

What Is Oat Milk?

Oat milk is non-dairy milk that is gotten from soaking, blending, and sieving oats with water. Oats provide useful nutrients when consumed and the process of making oat milk retains a majority of these nutrients.

Consuming oat milk will give you the following nutrients:

  • Vitamin A, B2, B12, and D.
  • Calcium
  • Magnesium
  • Iron
  • Protein
  • Riboflavin, phosphorus, and potassium.

Just looking at the nutrients you can get from oat milk is enough to have you drinking a cup a day. Not to mention that a lot of moms, myself included, love the creamy texture of the milk. It makes oat milk all the more desirable.

Benefits Of Oat Milk

Asides from the nutrients you derive, oat milk provides a lot of other advantages to you as a lactating mother.


One thing I love about this plant-based milk is that it poses no allergic reactions whatsoever to you or your baby. There is no presence of eggs, soy, dairy, or nuts which are the most common allergens.

You should note that you risk no allergic reactions if the oat milk is certified gluten-free. However, many brands use whole wheat which causes the presence of gluten in oat milk. Of course, this applies to you if you are gluten intolerant.

2.Rich In Fiber

Oat milk is packed with soluble fibers, quite more than other non-dairy products.

A lot of people link weight loss to oat milk. Although oat milk does not directly impact weight, the soluble fibers in them can make you feel full faster, so you eat less and thus lose weight. Such a great way to lose some of that pregnancy fat!

The fiber in oat milk also helps reduce cholesterol levels, prevents constipation, regulates blood sugar levels, and lowers the chances of certain cancers and heart diseases.

3.Low In Fat

This feature may also be part of the reasons why you would hear moms saying oat milk made them lose some weight.

Oat milk contains a small amount of fat so it doesn’t give you a couple of pounds while you’re breastfeeding(what a relief!).

The amount of fat in oat milk is significantly less than in other non-dairy milk variants.

4. Environmentally Friendly

When I was consuming oat milk to increase my milk supply I had peace of mind knowing that I was reducing my carbon footprint.

For one, oat milk requires a considerably less amount of water in the manufacturing process than dairy milk and its close cousin, almond milk.

Dairy cows produce a large amount of methane which is much more impactful than carbon IV oxide. Methane makes up the majority of dairy milk carbon emissions. All the more reasons to stick to our lovely oat milk.

Does Oat Milk Increase Milk Supply When Breastfeeding?

Yes, oat milk can lead to an increase in breast milk supply. There has been no scientific research as to whether oat milk increases the supply of breast milk.

However, a lot of women report a significant increase in milk supply during the consumption of oat milk. So much so that even lactating consultants recommend it to breastfeeding mothers.

How Can Oat Milk Increase Milk Supply?

Many women experience deficiencies in iron and folate which can result in anemia and turn reduce breast supply (1) . As stated earlier, oat milk is highly rich in iron.

Postpartum moms can experience anemia for up to 6 or even 12 months. And that’s after pregnancy!

This drop in the level of iron stores in the body will affect your breast milk volume, mostly reducing your supply. Drinking oat milk will revitalize the iron level in your body and so increase your milk supply.

Painful nipples, clogged milk ducts, and milk blebs along with any other breastfeeding problem can be fought with oat milk. This is because the right level of irons in your body will boost your immune system.

In addition, some other nutrients contained in oat milk have a positive effect on the quality and quantity of milk produced by a breastfeeding mother. These are protein, fibers, carbohydrates, beta-glucan, and phytochemicals.

Oats are comfort food and when consumed causes you to relax. When your body is calm, it produces oxytocin, a hormone that stimulates breast milk production.

Since oat milk lowers cholesterol levels, its consumption will leave you much healthier and even improve your lactation.

How Quickly Does Oat Milk Increase Milk Supply?

After I had consumed oat milk consistently for a few days, I began to pump about 2 – 3 additional ounces of milk. It doesn’t seem like much but it was highly relieving for me as a breastfeeding mom.

Some mothers say that start seeing an increase in supply as early as 6 hours after consuming oat milk. That’s pretty quick, right?

How soon you start to see changes depends on how much oat milk you consume, your body’s metabolic rate, and other factors. Just observe the levels of increase in supply for every quantity of oat milk you consume. So, you’ll be able to determine how oat milk works for you.

How Much Oat Milk Should I Drink To Boost Milk Supply?

The daily consumption of calcium for a lactating mom is about 1300mg. So if you want to meet up with that then you should take at least three and half a cup of oat milk each day.

Otherwise, try to consume as much oat milk as you can. It has many benefits and can only be useful to you. Again the amount you need to consume for increased milk supply is dependent on factors relating to your body.
