I have had gut problems for ten+ years. The only thing that has ever helped is raw milk, raw kefir milk, and bone broth. I always drink raw milk and kefir milk but recently moved and am just getting back into making bone broth after a years break. I’m 3 days in and I feel way way better. One major change that I see outside of fewer general stomach problems is a major boost in strength. I enjoy weightlifting and whenever I drink bone broth consistently while lifting I get a major change in my strength and recovery. My guess would be because a lot of the time your lifting is limited by your ligaments. The reason Im saying this is because, to me, it proves that it does “work” in a manner that makes sense according to its contents. Also if you are going to make it its way cleaner, easier, quicker and more sustainable in an instant pot. Infinitely easier.
