Low-lactose vs lactose-free
"Lactose-free" on a label has a specific meaning in each country's food rules; "low lactose" or "virtually lactose-free" do not promise zero. If you need zero dairy, pick a product made without milk and check the allergen statement for shared-factory warnings.
If small amounts are fine for you, the cheapest whey isolate is often cheaper per kg of protein than dairy-free powders.
FAQ
Is whey isolate lactose-free?
Not usually. Isolate is filtered to remove most lactose, so it is typically low in lactose, but small amounts remain unless the label says lactose-free. People with lactose intolerance react to different amounts; ask your doctor or dietitian.
Which protein powders contain no dairy at all?
Plant proteins (pea, rice, soy, fava), beef protein isolate and egg white protein are made without milk. Check the label for "may contain milk" warnings from shared factories.
