What protein to take if you are lactose intolerant

Melanie Ramos 6 min. of reading Proteins Leave a comment

Are you lactose intolerant? You’re not alone. More and more people experience digestive discomfort such as bloating, gas, or intestinal pain after consuming it.

Lactose is a sugar found in milk and dairy products that requires a specific enzyme, lactase, for proper digestion. When this enzyme decreases — something that can happen if we stop consuming lactose for long periods — intolerance symptoms begin to appear.

That’s why, if you reintroduce it without prior adaptation, your digestive system will likely notice… and not in a good way.

Most proteins supplements are made from whey, meaning they naturally contain lactose. This can be an issue for intolerant individuals if they don’t choose carefully.

However, nowadays there are many high-quality alternatives that are lactose-free or contain virtually no lactose, perfectly suited to your needs.

How to know if a protein contains lactose

Identifying lactose isn’t complicated; you just need to know where to look on the nutrition label. Lactose is essentially the intrinsic sugar in milk.

To detect its presence, check the nutrition facts table:

Look for the “Carbohydrates” section and, within it, the “Sugars” subcategory.

The golden rule: in a pure protein supplement, nearly all sugars from milk will be lactose. If the sugar value is very low (below 1g per 100g of product), it’s an excellent indicator that the lactose content is negligible or zero.

? Note: In gainers, the nutritional profile is altered due to added complex carbohydrates (such as maltodextrin or oats). You’ll need to review the ingredient list and verify whether the protein source is non-dairy, or—as we’ll see next—even if it is dairy-based, whether it is hydrolyzed.

The power of the plant kingdom: a guaranteed lactose-free alternative

If your lactose intolerance is severe, or you’ve chosen a plant-based diet, plant proteins are your best option. Far from being “second choices,” nutritional science has shown that sources like soy or pea provide an excellent amino acid profile, fully meeting the needs of athletes at any level.

The major advantage of these proteins is their inherently lactose-free origin. Since they don’t come from cow’s milk, there’s no risk of lactose traces, eliminating digestive concerns altogether.

At HSN, you can find a wide catalog of lactose-free plant proteins, such as:

Isolated Soy Protein: historically the benchmark for plant proteins. It has a complete amino acid profile, containing all essential amino acids required for protein synthesis. At HSN, we use high-purity soy isolates, ensuring a pleasant texture and very high protein content, ideal for those seeking performance comparable to whey, but fully dairy-free.
Isolated Pea Protein: has become a favorite for those seeking a hypoallergenic and gentle option for the stomach. It stands out for its high lysine and arginine content, essential amino acids for muscle development and maintenance. It’s highly valued for its digestive tolerance. If even whey isolates still feel heavy, pea protein is generally the most digestive-friendly option.

Hydrolyzed whey isolate: maximum purity and digestibility

If you’re looking for cutting-edge nutrition, hydrolyzed whey protein isolates represent the pinnacle of supplementation. Not only for their very high bioavailability, but also because their production process makes them an exceptionally safe option for those with moderate dairy sensitivity.

Advanced products, like our 100% Hydrolyzed Whey Protein Isolate (using high-quality Lacprodan® Hydro.90 INS), undergo combined filtration and hydrolysis processes. This treatment pre-digests the protein for near-instant absorption and also plays a key role: removing naturally occurring sugars from the source.

What makes these hydrolysates different?

Drastic lactose reduction: unlike other hydrolysates that retain residual sugars, high-purity formulas reduce lactose content to a minimum. If you have mild intolerance, you don’t have to give up high biological value protein.
Unmatched purity: hydrolyzed isolates can reach protein concentrations of up to 92%, meaning almost all fat and lactose are removed, resulting in an extremely clean nutritional profile.
Goodbye discomfort: hydrolysis breaks protein chains into shorter peptides, making digestion easier and reducing discomfort, while improving post-workout recovery.

? Choosing a hydrolyzed whey isolate isn’t just about performance; it’s a commitment to digestive health.

The refreshing alternative: “Clear” protein

Many lactose-intolerant users assume they must settle for dense textures or milky flavors. However, the “clear” process changes this. By adjusting the pH during processing, the protein dissolves into a transparent, juice-like drink.

Excellent technical base: Evoclear Hydro is a hydrolyzed whey isolate. Like other hydrolysates, it contains virtually no lactose.
Ultra-fast digestion: combining hydrolysis with a light texture ensures rapid absorption—ideal post-workout or when appetite is low.
Dairy-free experience: fruity flavors eliminate the “milkshake” sensation, which many intolerant users appreciate.

? If you’re lactose intolerant and want a fast-absorbing protein that feels more like a soft drink, Evoclear Hydro is an excellent choice.

Egg white protein: the “backup” lactose-free alternative

If you want a protein source with maximum biological value and guaranteed zero lactose, egg white protein—like Evoegg 2.0—is the most reliable option. For many athletes, it’s the essential “backup protein” when dairy is no longer viable.

Why is it the perfect whey substitute?

Evoegg 2.0 is made from pasteurized egg whites dehydrated via spray-drying, preserving their nutritional properties.

Complete amino acid profile: like whey, it contains all 9 essential amino acids and has an excellent biological value.
Zero lactose, zero dairy: no risk of dairy-related discomfort.
Excellent digestibility: easy on the stomach and efficient.
Texture and structure: great for recipes like pancakes or meringues.
Functional replacement: ideal as an egg substitute in baking.
Consistency: similar to whey shakes, making the transition easy.

? Expert note: this protein may foam more when shaken due to its natural properties. Let it rest briefly before drinking.
