What types of protein powder are lactose-free?

All vegan powders (pea, rice, soy, hemp) are lactose-free. Whey isolate contains very little lactose and is well tolerated by most people with intolerance. Casein and concentrate do contain lactose.

Is whey isolate always lactose-free?

Not always, but close. The extra filtration leaves less than 1% lactose. Most people with mild intolerance have no issues with it. For severe intolerance, vegan is the safer bet.

Are vegan powders better for lactose intolerance?

They're the safest choice since they're guaranteed lactose-free. For muscle building they work well, especially a pea and rice blend. The taste is different from whey though.

Can you still get good macros without lactose?

Absolutely. Lactose-free powders typically have 20-25g protein per scoop, comparable to regular whey. Your amino acid profile is complete with a good vegan blend or whey isolate.
