Lactose-free protein supplement

Best for: Dairy avoidance and people wanting a vegan option.

3. Egg-white protein

Typically supplies 20–25 g per serving and is a complete protein. It contains no lactose naturally, though you should check the full ingredient and allergen statement.

Best for: People who eat eggs but want to avoid dairy.

4. Beef protein isolate

Some products provide around 20–27 g per serving. Formulas vary, so check for added milk ingredients and verify the manufacturer's lactose statement.

Best for: People who want an animal-based, non-dairy alternative.

How to make sure it's completely lactose-free

• Choose a product explicitly labeled lactose-free or dairy-free, ideally both.
• For the clearest choice, avoid whey, milk protein, casein and milk powder. Whey isolate can have very low lactose, but low lactose isn't the same as a guarantee of zero.
• Check flavored versions separately; formulations and manufacturing statements can vary.
• If you have a milk allergy, choose a product with suitable allergen labeling and manufacturing precautions. Lactose intolerance and milk allergy are different conditions.

My recommendation

I'd start with a pea-and-rice protein blend for an everyday supplement, or egg-white protein if you want a complete animal-based protein without dairy.

One question so I can narrow this to the best two or three options for you: Are you avoiding lactose because of lactose intolerance, or do you need to avoid all dairy completely (including milk proteins)?

Here are the best options available:

Plant proteins contain zero dairy, making them the safest bet for complete avoidance of lactose. Modern formulas blend different plants to ensure a complete amino acid profile.[aloha.com](https://drinkkoia.com/collections/lactose-free-protein-shakes)[[2](https://paleopro.com/blogs/news/dairy-free-protein-powder-guide)](https://aloha.com/collections/lactose-free-protein-powder)

If you prefer an animal-based protein but cannot tolerate whey or casein, beef protein isolate is made from hydrolyzed beef/collagen sources.[aloha.com](https://paleopro.com/blogs/news/dairy-free-protein-powder-guide)

To help narrow this down, let me know:

• How severe is your lactose intolerance? (Do you react to trace amounts, or just heavy dairy?)
• Do you have any preferences for artificial vs. natural sweeteners?
