It's not dairy-free, though ghee may be a good choice for people who are lactose-intolerant. That's because it contains extremely low levels of lactose and casein (a milk protein).
Does ghee contain casein?
It comes from butter, but it's lactose-free and casein-free. Crazy! During the simmering process, all the lactose and water is filtered off, meaning ghee is lactose-free, casein-free and shelf-stable.
Does butter have casein?
Butter has small amounts of casein, so people with mild casein sensitivity may be able to tolerate butter in moderation, but for others, even a little bit of butter can cause a flare-up.
