Frequently Asked Questions (FAQs)

1. Which whey protein is lactose free?

Whey protein isolate is lactose-free, as it is made from the milk protein without lactose. If you are lactose intolerant or have become lactose intolerant, whey isolate is the best choice for you. On the other hand, regular whey protein contains lactose.

2. Does lactose-free whey protein exist?

Yes, lactose-intolerant individuals can still benefit from whey protein. Whey protein isolate is a good option as it has a minimum purity of 90% protein and contains little to no lactose in the final product. This can help limit the likelihood of discomfort for those with lactose intolerance.

3. What protein powder does not have lactose?

Plant-based protein powders such as pea, hemp, pumpkin, soy, and brown rice generally do not contain lactose. However, it is important to double-check the label if the product is not specifically marketed as vegan. Vegan protein powders and egg white protein powders are also lactose-free options.

4. Can you get lactose-free protein powder?

Yes, there are lactose-free protein powders available. Plant-based options like pea, hemp, and soy protein powders are lactose-free and suitable for individuals with lactose intolerance or allergies. These protein powders offer the benefits of protein supplementation without the discomfort or issues associated with lactose intolerance.

5. Can I have whey protein if I'm allergic to dairy?

No, whey protein is not safe for individuals with dairy allergies. People with dairy allergies have an immune response to the proteins found in milk products, including whey protein. Consuming whey protein can trigger an allergic reaction, either IgE-mediated or non-IgE mediated, depending on the individual's specific allergy.
