I have just found that some flavoured yogurt contain Gelatin in them.
Make sure to always check the ingredients before you buy them.
Who can imagine beef gelatin in yogurt.
Why does Yoplait use gelatin?
Gelatin gives consistency and texture to yogurt and Yoplait uses kosher gelatin that’s beef-derived. Yoplait yogurt carries KD (Kosher Dairy) Certification, certified by Rabbi Barnett Hasden. New Yoplait Greek and Yoplait Greek 100 are great options for those looking for a gelatin-free Yoplait option.

Please check the brand of your flavoured yogurt if you eat any.
