FAQ

What type of protein powder is lactose-free?

While the most common type of protein powder is made from whey, there are many different types of protein powder that are naturally lactose-free. These include vegan protein powders made from plant sources such as soy, rice, and pea. There are also many lactose-free protein powders made from whey, which have had the lactose removed during the manufacturing process.

Is whey protein powder lactose-free?

Most whey protein powders and mass gainers do contain lactose, as they are made from dairy protein and lactose naturally occurs in dairy. However, whey isolate protein products are processed to remove the lactose, making them suitable for those who are intolerant or sensitive to dairy.

Is casein protein powder lactose-free?

Casein protein powder is made from milk, so it does contain lactose. Casein is a popular choice for those wanting a slow-release protein powder, but it's not the best option for those who are lactose-intolerant.

Do all protein powders contain dairy?

Not all protein powders contain dairy. There are many plant-based protein powders available that do not contain any animal products. Whey isolate is a popular type of protein powder for lactose-intolerant people as it is processed to remove the whey. There are also protein powders made from eggs, collagen, and beef. These protein supplements are an excellent choice for anyone who is lactose intolerant but prefers animal sources of protein.

Is whey protein vegan?

Whey protein is not vegan, as it is made from dairy. However, there are many plant-based protein powders available that are suitable for vegans. Check out our blog for more nutrition advice if you're vegan.

Are plant-based proteins as good as whey protein?

Plant-based proteins are a great alternative to whey protein for vegans and people who are intolerant to dairy. However, whey protein is considered to be a complete protein as it contains all of the essential amino acids. Plant-based proteins often include several sources of protein in order to get a full spectrum of amino acids.

Studies comparing the effectiveness of whey and plant-based protein powders have found that there is no significant difference in terms of strength and muscle growth (1, 2, 3).

Are there any side effects from using lactose-free protein powders?

There are no known side effects from using lactose-free protein powders. However, as with any dietary supplement, it is always best to speak to a qualified healthcare professional before starting any new supplement regimen.

Why does whey protein make me bloated?

Whey protein is a dairy product and, therefore, may be more difficult to digest for people who are sensitive to dairy. The lactose content in whey protein can cause bloating and other digestive issues in some people, as well as an uncomfortable full feeling in the stomach (4, 5). If you experience these side effects after using whey protein powder, it may be best to switch to a lactose-free option.

How do I know if I’m lactose intolerant?

If you experience bloating, gas, or other digestive issues after consuming dairy products, it is possible that you are lactose intolerant. You may also experience these symptoms after using whey protein powder. If you are unsure whether you are intolerant to dairy, it is best to speak to a qualified healthcare professional.

What is the best lactose-free protein powder?

There is no one "best" lactose-free protein powder, as different people may prefer different types of protein. Some people prefer the taste and texture of whey protein, while others find plant-based protein powders to be easier to digest.

It is also important to consider your dietary needs and goals when choosing a protein powder. For example, vegans will want to opt for a plant-based protein powder, while lactose-free whey powder is an acceptable choice for non-vegans.
