Whey protein isolate lactose free

Do not infer a lactose-free claim solely from the word isolate. Check the exact product label and ask the manufacturer about the claim and testing behind it. Milk-allergen information and lactose content answer different questions; use the label for the product you are considering.

Compare the exact label

1. Identify the product and serving size.
2. Read the full ingredients and allergen information.
3. Check servings per container and delivered cost.
4. Ask the manufacturer about any unclear claim.

Use the current product listing, shipping terms and return policy for your order. This guide does not recommend a dose or promise a health outcome.
