I use the Instant Pot, which has a yogurt-making feature/button. But it turns off at eight hours, and stays on keep warm mode. I just unplug and replug to do another eight hours. I only do 16 hours. It gets tart.
I use inulin as well. I follow the procedure of Dr. William Davis.
I have not experienced gas side effects.
I make the yogurt for the reuteri. I put about two capsules of BB-12 per half gallon of milk. Haven’t noticed any difference. I prefer oyster mushrooms (pleurotus ostreatus) and shiitake for spermidine.
Please. No more Bryan Johnson. I am not a fan like you.
