Can I Have Whey Isolate If I Am Lactose Intolerant?

If you're lactose intolerant, you might assume that whey protein—derived from milk—is off-limits. However, not all whey proteins are created equal. Whey protein isolate is a specialized form of whey that is typically safe for people with lactose intolerance.

Why Can Lactose Intolerant People Have Whey Isolate?

1. Minimal Lactose Content

Whey isolate undergoes extensive processing to remove lactose. While whey concentrate contains more lactose, whey isolate is virtually lactose-free, with only trace amounts remaining—usually less than 1 gram per serving.

2. Easy Digestibility

Because whey isolate is almost pure protein, it’s easier on the stomach and less likely to trigger symptoms associated with lactose intolerance.

3. Nutritional Benefits Without the Discomfort

Lactose intolerant individuals can enjoy the muscle-building and recovery benefits of whey isolate without worrying about digestive upset.
