How much lactose is there in casein?

There is no sugar added to any Tigerwhey casein product. The Unflavored Casein contains 5.0 grams of carbohydrate per 100 grams of powder. One serving size of 30 grams Unflavored Casein contains 1.5 grams of carbohydrate, while the flavored powders contain a few percent less. The carbohydrate in this product is the natural milk sugar from the source milk, meaning that all this carbohydrate is lactose. People with lactose intolerance should consider whether this product is suitable for them.

It can be noted that the 1.5 grams of lactose per serving is very low, so people with lactose intolerance may not notice any inconvenience at all. As a comparison, one cup of milk (250 milliliters) contains 12 grams of lactose and one 30 gram serving of Tigerwhey casein powder contains 1.5 grams of lactose. This means that one serving of Tigerwhey casein contains only 12.5% of the amount of lactose in one cup of milk. Or in other words, one serving of Tigerwhey casein powder contains the same amount of lactose as what you get in 31 milliliters of milk. This is the same amount as in two US tablespoons of milk. Most people with lactose intolerance can tolerate up to 2 cups (500 milliliters) of milk a day, when divided into smaller quantities.

Summing it up: Tigerwhey casein powder contains lactose, but it is not much. If you have questions about lactose intolerance and the use of protein powder, please send us your questions in an email and we will get back to you.
