1. Drinking Too Much Too Fast
Kefir is packed with probiotics, and suddenly consuming large amounts can overwhelm your digestive system.
Tip: Start with ½ cup per day and gradually increase to 1–2 cups.
2. Using Non-Fermented or Sweetened Kefir
Flavored or overly sweet kefir can spike blood sugar and reduce probiotic benefits.
Tip: Choose plain, unsweetened kefir or make your own at home.
3. Ignoring Storage Instructions
