For myself, first thing in AM, I drink a large glass of water. About 10-15 minutes later I drink a small glass of organic A2/A2 low fat plain Keifer, which helps our microbiome (a huge part of our immune system), eat a low fat plain yogurt with a few blueberries and a few crumbled walnuts first, then I immediately take my Prednisone with another big glass of water.
A2/A2 keifer is made in such a way that Lactose intolerant people can drink it with no issues. I'm highly lactose intolerant. Also the yogurt I can eat with no issues is Trader Joe's low fat plain Greek yogurt. Something about the way Greek yogurt is made, but only that brand does bother my stomach. For myself, as long as I've been taking Prednisone (only since 7/31/26), I haven't had any stomach issues since I've eaten as above first. Tried taking it without the Keifer and yogurt in the beginning and my stomach hurt and felt really full of acid. Nothing at all this way. I hope it might help someone.
The better meal you eat first, probably means better outcome with the stomach. Oatmeal is a good one too.
