HOW TO ENJOY IT ON KETO

  • Moderate net carbs (~4g/100g) fit most keto plans with portion control
  • Strained/fermented dairy reduces lactose vs. milk, improving carb profile
  • Full-fat versions support satiety better than low-fat
  • Probiotic food that can complement gut health on keto
  • Versatile in smoothies, dressings, and marinades
  • Choose unsweetened to avoid added sugars

HEALTH BENEFITS

  • Provides diverse live cultures that may support digestive and immune health (brand-dependent)
  • Good source of bioavailable calcium
  • Contains B vitamins that aid energy metabolism
  • May include small amounts of vitamin K2 in full-fat fermented dairy
  • Dairy fats can aid absorption of fat-soluble vitamins (A, D, E, K)
  • Tangy, fermented profile may improve meal satisfaction
