Are you lactose intolerant? Have you noticed any stomach issues whenever you eat or drink something with dairy in it?

Dairy can cause abdominal discomfort due to the presence of lactose, the sugar found in milk. If you are one of those people affected by it, you may have noticed that some protein powders can also cause an upset stomach. 

But that doesn’t mean you have to stop having your post-workout protein shakes.

In this article, we will look at the best lactose-free protein powder options available on the market. You’ll be able to enjoy all the benefits of lactose-free protein supplements without suffering any side effects.

Which Protein Powders Are Considered Lactose-Free?

There are countless protein powders available on the market nowadays, but most of them are sourced from milk, such as whey and casein protein powders. 

Because of their origin, they often contain traces of lactose, especially if manufactured in environments where milk is handled for the production of other products. 

The level of purification that has been performed during extraction also plays an important role. Usually, “concentrate” proteins contain more lactose than “isolated” or “hydrolyzed” alternatives, as their extraction process is less meticulous. 

However, if handled well by the manufacturers, whey isolate proteins can be lactose-free. Other lactose-free protein powder options include the following:

  • Egg protein
  • Plant/vegan protein blends
  • Collagen (animal and marine sources)
  • Nuts
  • Insects (e.g., crickets) 

These sources of protein are particularly important for those suffering from lactose intolerance. This condition occurs in the majority of adults due to a physiological reduction in the lactase enzyme following weaning. 

Lactose is a disaccharide, which is a sugar composed of two molecules: glucose and galactose. A lack of lactase means that our body struggles to break down, digest, and absorb this milk sugar, resulting in abdominal discomfort and gastric distress. 

People who suffer from this intolerance would therefore benefit from consuming protein powders that do not contain lactose. Vegans can also benefit from lactose-free protein blends, as plant-based proteins don’t contain any lactose.

How to Choose a Lactose-Free Protein Powder

Here are some tips to help you choose your lactose-free proteins:

Go with Isolates

Protein isolates are considered a higher quality form of protein than concentrates. This is because they have been extracted into a purer form and provide higher digestibility and bioavailability.

Opt for Bioavailability

Keep in mind the importance of bioavailability, which is the amount of protein that is usable by our body for physiological functions. Despite plant-based blends still being a great protein source, they tend to have lower bioavailability compared to their animal-sourced counterparts, such as eggs, beef, and lactose-free whey.  

Mix Your Plants

If picking a vegan protein powder, opt for blends made using different plant sources, as these tend to provide more essential amino acids and therefore provide better quality proteins.  

Does Your Shake Mix Well?

Mixability, or solubility, is also very important as a low mixability can not only make your shake unpleasant to drink, but it can also lower its absorption in your body. So make sure your protein mixes well with your liquids to increase your protein absorption. [8]

Check the Label

Check the labeling to always ensure the product you are picking up is free from lactose. Milk and dairy are commonly handled ingredients in the food industry so contamination can occur. 

In this case, it should be stated on the labels under the allergen section, but also double-check the ingredient list to ensure no lactose-containing item has been added to the protein blend. 

Is It Really Lactose-Free?

Some online information may lead you to believe that all whey isolate proteins are free from lactose due to their extraction process. However, be aware that, unfortunately, this is not the case. You can certainly find some lactose-free whey protein options on the market, but ensure that this is stated on the product labels or in the product description before purchasing it.

Look for the Essentials

If you want to build muscle, make sure to buy proteins that provide all essential amino acids to support both the growth and development of muscle tissue. 

If this is your goal, you should also pair your diet with a hypertrophy-focused workout program, which can easily be designed using a workout app. [9]

How to Mix Your Lactose-Free Protein

Whether you are about to have breakfast or a post-workout snack, the last thing you want to add to a protein shake for lactose-intolerant people is cow’s milk. This would defeat the purpose of consuming a dairy-free protein powder. If you’re intolerant to lactose, here are the best liquid alternatives to mix with your shakes: 


Water is a great alternative, especially for those following a specific diet or training plan. However, mixing protein with water may not provide the best taste, so it is worth trying it out with a small amount of powder to avoid wasting the product. 

Plant-Based Alternatives

Plant-based milk has taken over the market in the past few years, so you should be able to find pretty much any type of plant milk you prefer: oat, hazelnut, almond, rice, coconut, etc.

However, these plant milks have different flavors and nutritional characteristics, so make sure to pick the one that you like the most or that is in line with your health and fitness goals. 

Lactose-Free Milk

Even if you are intolerant to milk, you can still enjoy cow’s milk as long as you pick the lactose-free version. This milk contains lactase, which supports digestion and prevents side effects by breaking down lactose for you. 

Final Words

Lactose-free proteins are widely available on the market, with new products coming out every year. Below are the key points from today’s article:

  • The majority of people start to develop lactose intolerance as they grow older.
  • Lactose-free protein powders are a great option for those suffering from this intolerance and vegans also need to ensure they are consuming protein powders obtained from plants.
  • There are many alternative protein sources for those avoiding dairy, such as eggs, beef, chicken, grains, nuts, and plants.

  • If going vegan, choose a blend that is made with different plant-based sources, so as to have all essential amino acids and to improve overall protein quality.
  • Mixability and solubility of a powder can affect taste and texture but also absorption, so make sure to choose proteins that mix well with liquids.
  • Some whey proteins can be lactose-free, as long as they are certified and it is stated in the claims.
  • You can use different liquids as alternatives to cow’s milk to make your protein shakes, such as water, plant-based milk, and lactose-free milk.
