might be able to have whey isolate if lactose intolerant

If I’m sensitive to lactose, should I avoid whey protein?

If you are lactose intolerant, or sensitive to lactose, the natural sugar found in milk products, you may be able to tolerate whey protein isolate, which contains very little lactose. The amount of lactose in whey protein concentrate is higher. As always, it is important to contact the manufacturer as lactose content can vary from product to product.
