Putting some butter in coffee can provide you with some health benefits so yes butter coffee is good for you and your health.
But the butter in coffee is something that you might have to get used too as for the taste.
I tried butter coffee before and could not get used to the taste but some people eventually do get used to the taste of butter coffee.
Adding Butter to your coffee can help reduce jitters and crashes and the butter added to coffee also has the Vitamins A, K, D & E which help improve your health.
But drinking butter coffee too much could cause an increase risk for heart disease due to the high fat content that butter contains.
So only drink butter coffee once every few days to avoid heart issues and also butter coffee can cause you to gain weight due to the high fat content that butter contains so if you're trying to lose weight then butter coffee isn't a good option.
Still though in moderation butter coffee is healthy but don't overdo it.
