Is whey protein powder lactose free?

It depends on the specific whey protein powder. Some whey protein powders are lactose-free, meaning they contain little to no lactose. This can be beneficial for individuals who are lactose intolerant, as it allows them to still get the benefits of whey protein without experiencing the digestive discomfort associated with lactose intolerance.

However, not all whey protein powders are lactose-free, so it is important to check the ingredient list and label carefully to determine the lactose content of a specific product. In general, less expensive whey concentrates contain more lactose. However, isolates and hydrolyzed whey contain minimal to no lactose depending on processing.

If you are lactose intolerant, it may be advisable to use a non-dairy protein source.
