Lactose and Milk Free Protein Powders

Lactose Free Whey Protein Isolate

Lactose Free Whey Protein Isolate

Good News! There are plenty of lactose free protein powders available, and there are many that do not contain milk ingredients either.

Most of the high-quality protein powders on the market these days come from milk. Whey and Casein protein are the most popular proteins supplements and are derived from milk and therefore contain milk sugars, commonly called lactose.

I have also listed some milk free protein powders at the end of the article.

Why do I need a Lactose Free Protein Powder?

Unfortunately, there are many people that suffer from Lactose Intolerance, and cannot easily tolerate or digest lactose. These people need a high-quality protein powder that is lactose free.

Also see my article on Best Vegan Protein Powders.

Lactose Intolerance is caused by a lack of sufficient lactase, which is the enzyme that digests lactose in the small intestine.

Check out this very short explanation from Jim Stoppani, PhD:

More and more people are taking protein supplements these days and people with lactose intolerance are no exception. Why should you miss out on all the benefits of protein powders supplements just because you don’t digest milk or dairy product very well? You should not miss out and that is what this article is all about. I want to show you there are is a good selection of all types of powders that are lactose free for you to enjoy!

See article Do I Need Protein Powder to Build Muscle?

I have researched many of the most popular protein powders on the market and have come up with a list of lactose free protein powders that are pretty high in purity. Purity refers to the actual percentage of protein contain in a product. Some products might be 60% pure, meaning the remaining 40% is made up of fillers, flavorings, other ingredients that are not actual protein. Since protein powder is expensive, you definitely  do not want to pay for a lot of ingredients that are not actually protein.

There will always be some percentage of other ingredients, in order to make the powder taste good, mix well, and resist spoiling there must always be some other ingredients.

What kinds of Protein Powders are Considered Lactose Free?

There are several types of powders that are lactose free.

  • Whey Isolate
  • Beef Protein Powder
  • Plant based protein powder

Whey Isolate is milk based, but most or all of the lactose is processed out, making it essentially lactose free.

Whey protein comes in three common forms: Whey concentrate, whey isolate and whey hydrolysate. Whey concentrate is the cheaper and less processed protein, and does contain lactose. Whey Protein Isolate is a very pure form of whey protein, and is considered lactose free as is whey hydrolysate.

Whey-based lactose free protein powder is going to have higher purity than most other types of proteins because whey is high in protein to begin with, and processing will increase this percentage even further.

Although a lot of people that suffer from lactose intolerance and can actually consume most whey proteins without issues, you will want to go with protein powders that are made of whey protein isolate.

There are many plants such as peas, rice, hemp and soy that contain high concentrations of protein and through processing can be converted into a very high-quality protein powder. The percentage of actual protein in each scoop is a bit lower in plant-based protein powders, simply because most plants start with a lower concentration of protein than milk does.

These are ranked by purity from some of the biggest names in supplements. Purity calculations unless otherwise noted are based on Vanilla flavor. (The purity percentage will sometimes be very slightly different on other flavors, and the variance is typically a couple percentage points.)
