To get frozen yogurt as it’s normal consistency, you also have to add a lot of sugar. Like more sugar than ice cream. Also there is questionable value to the probiotic nature after freezing it.
What kind of yogurt do you usually get? What kind of texture do you want? Because store bought stuff has quite the range. Yoplait basic low end yogurt is practically drinkable, but their “Oui” brand French style yogurt is practically chewable. I really like the Oui but it’s also kind of expensive for what you get so I usually opt to get Greek style because everyone makes it, it’s good, and usually also cheap.
You might also want to try Kefir. It’s probiotic but much more like drinking milk than yogurt. It’s not quite either, but something in between. I pound one of these whenever I’m constipated and it really gets shit moving again, in a literal sense.
