Yes, butter is low histamine. However, many people experiencing histamine issues don’t tolerate dairy products well, so it’s recommended that you wait at least one month into an elimination diet before trying to reintroduce dairy. This is because, even though lactose intolerance is a common reason for issues with dairy products, histamine issues often co-occur with gluten and dairy intolerances, as in cases of SIBO or irritable bowel syndrome. After an initial period of calming the gut, most people can safely reintroduce dairy and use butter in any dish they’d like.
