Q: Is whey gluten-free?


Yes, whey is a milk protein and is naturally gluten-free. Pure whey should be safe on the gluten-free diet. However, always read the label and confirm GF status on whey powders as other ingredients are often added.

Another thing to note is that since whey is a milk protein it may not be suitable for those who have a sensitivity to dairy protein or a milk allergy. However, whey is generally low in lactose, and may be tolerated by those with lactose intolerance depending on sensitivity and the amount of lactose present.
