How to Identify Probiotic Yogurt
To find yogurts with active probiotics, look for specific details on the packaging. Not all yogurts contain live cultures, particularly if they have been heat-treated after fermentation to extend shelf life.
The "Live and Active Cultures" (LAC) Seal
A key indicator is the "Live and Active Cultures" (LAC) seal, a voluntary certification by the IDFA and National Yogurt Association (NYA). This seal indicates that the yogurt contained a significant amount of living bacteria when manufactured. While helpful, some yogurts without the seal may still contain active cultures.
Reading the Ingredient List
Check the ingredient list for specific probiotic strains. Common beneficial bacteria include Lactobacillus bulgaricus, Streptococcus thermophilus, Lactobacillus acidophilus, Bifidobacterium, and Lactobacillus casei. A diverse list of strains can offer broader benefits.
Avoiding Heat-Treated Products
Yogurts heated after fermentation have their live cultures destroyed. These products won't offer the probiotic benefits of cultured yogurt. Look for labels indicating post-fermentation pasteurization and avoid them for probiotic benefits.
Popular Yogurt Brands with Active Probiotics
Several brands are known for including active cultures:
- Dannon's Activia: Contains the specific strain Bifidobacterium animalis lactis DN-173 010.
- Chobani: Offers Greek yogurt with a mix of strains like Lactobacillus acidophilus and Bifidobacterium animalis.
- Fage: Provides Greek yogurt with a blend of Lactobacillus and Bifidobacterium strains.
- Stonyfield Organic: Features both regular and Greek yogurts with live active cultures.
- Siggi's Icelandic Style Skyr: High in protein with live and active cultures.
- Yoplait: Many varieties include Lactobacillus bulgaricus and Streptococcus thermophilus.
Yogurt Style Comparison: Probiotics at a Glance
| Yogurt Style | Probiotic Content | Protein Level | Texture | What to Know |
|---|---|---|---|---|
| Regular | Good, if not heat-treated | Moderate | Thin, creamy | Often contains standard cultures like L. bulgaricus and S. thermophilus. |
| Greek Yogurt | Excellent, concentrated | High | Thick, strained | Straining increases protein and often probiotics. |
| Icelandic Skyr | Excellent | Very High | Thick, dense | Uses more milk than regular yogurt for high protein and cultures. |
| Kefir | Excellent, diverse | Moderate | Drinkable | A fermented milk drink with a wider variety of probiotic strains than most yogurts. |
| Frozen Yogurt | Varies, often lower | Varies | Solid | Freezing can reduce active cultures, and some are heat-treated. |
What to Watch Out For
Be mindful of added sugars in flavored yogurts, as high amounts can detract from the health benefits. Plain, unsweetened yogurt with added fruit or honey is a healthier option. Also, be cautious of products marketed as "probiotic" without listing specific live cultures.
Optimizing Your Probiotic Intake
To maximize the benefits of probiotic yogurt:
- Check Freshness Dates: Fresher yogurt typically has a higher count of live cultures.
- Pair with Prebiotics: Consume yogurt with prebiotic foods like oats, bananas, or onions to nourish the beneficial bacteria.
- Avoid Heating: Heat kills live cultures, so eat yogurt raw.
- Choose Plain: Plain yogurt allows you to control sugar and flavor.

Conclusion
Selecting yogurt with active probiotics is easy by looking for the "Live and Active Cultures" seal or checking for specific bacterial strains on the ingredient list. By avoiding added sugars and choosing styles like Greek or Icelandic skyr, you can enjoy a delicious and nutritious food that promotes gut health.
