This is was my first purchase of the Tallow butter with magnesium. I wanted the smaller size to see if it would be right for me to see if I would order the bigger size in the future if it did work well for me. I experience migraines and headaches often. I ended up having a headache the other night and used some at the nape of my neck and it worked so effortlessly! I have also been using it on my knees since it is starting to get colder out, which makes my knees ache. This is a great product. I would recommend to get this size if you have been on the fence about trying it. I guarantee you will end up getting the bigger size in the future! But it will be later on down the road because a little goes a LONG way with this tallow butter, so you’ll have the smaller size for a good amount of time!
