Now, you might be thinking, “But yogurt has probiotics! Those gut buddies are magical!” And you’re right—except your gut bacteria don’t make B12. In fact, most of the friendly bacteria in yogurt need B12 to survive; they don’t produce it. It’s like having a houseguest who eats all your food but doesn’t chip in for groceries. Rude.
However, there’s a special guest star: Lactobacillus reuteri. This little champ does make a tiny bit of B12 in your gut, but it’s like trying to fill a swimming pool with a squirt gun. You’ll still need external sources—like yogurt, if you’re desperate.
