You will definitely not find a multi that includes a meaningful dose of TUDCA. It is a very expensive ingredient.
Nor will 3-500mg even make you feel better at this point. You would need 900-1,000 to even hope to help. If you start pricing this you’ll probably be put off from trying it.
As someone who has used DMZ at least 4 times now, with a lot of support, I feel confident in saying you aren’t going to “out-support” it once you feel bleh, if it’s not the Kratom to blame. DMZ pretty much starts crushing my appetite by end of week 2. If I put my support list up it would probably blow some people’s minds - like 50 caps/day on a blast of various vitamins, minerals, antioxidants, health supplements. And that still doesn’t prevent this.
