4/5“Slippery elm helped a little too if you haven’t tried that but it didn’t as much for me.”
4/5 Taste & texture“yh exactly that, BPC 157 is a peptide so i can’t really recommend it you would have to do your own research, slippery elm i did one capsule a day in tea and one swallowed as i tried to help my LPR, it didn’t do too much however.”
4/5“In regards to the slippery elm dose, its better to use room temperature water as heat can make it coagulate it too early, so I just prefer to have room temperature.”
1/5 Urgency & loose stools“I bought slippery elm capsules today hoping they do something 😓 I get watery diarrhoea too but I think the absolute worst thing is when I have to go every twenty minutes just for a small bit to come out I’m like just come out all at once 😭”
2/5“Slippery elm too I guess but didn't help me”
