Understanding Cultured Yogurt
At its core, all yogurt is 'cultured' or fermented milk. However, the term "cultured yogurt" is often used to refer to products that contain live and active bacterial cultures at the point of sale. The fermentation process uses specific bacteria, typically Lactobacillus bulgaricus and Streptococcus thermophilus, to convert milk's lactose into lactic acid, which gives yogurt its characteristic tangy taste and thick consistency. Some manufacturers heat-treat their products after fermentation to extend shelf life, a process that kills these beneficial microbes. For true probiotic benefits, it's essential to seek out brands that explicitly state they contain live and active cultures.
How to Identify Cultured Yogurt
Shoppers can ensure they are getting a truly cultured product by looking for a few key indicators on the packaging.
The 'Live & Active Cultures' (LAC) Seal
An easy way to verify a yogurt's live culture content is to look for the voluntary seal from the National Yogurt Association (NYA). This seal indicates that the product contained at least 100 million live and active cultures per gram at the time of manufacture. While a helpful guide, it is important to note that the presence of the seal is voluntary, and some brands with live cultures may not carry it.
Reading the Ingredient List
For yogurts without the seal, a quick look at the ingredients list is necessary. Manufacturers must list the specific bacterial strains used. Key probiotic strains to look for include:
- Lactobacillus acidophilus
- Bifidobacterium lactis (or other Bifidobacterium strains)
- Lactobacillus casei
- Lactobacillus rhamnosus
Checking the Label for Heat Treatment
If a label mentions that the product has been 'heat-treated' or 'pasteurized' after fermentation, the live cultures may have been killed. This is more common in frozen yogurt or certain shelf-stable products. For maximum health benefits, opt for refrigerated options that emphasize the presence of live cultures.

The Health Benefits of Consuming Cultured Yogurt
Incorporating cultured yogurt with live probiotics into your diet can support overall well-being in several ways:
- Improved Gut Health: Probiotics help balance the gut's microbiome, which can improve digestion and potentially alleviate symptoms of issues like constipation and IBS.
- Nutrient Absorption: A healthy gut environment can enhance the body's ability to absorb essential vitamins and minerals.
- Immune Support: A significant portion of the immune system resides in the gut, and maintaining a healthy gut flora can support overall immune function.
- Weight Management: High-protein options like Greek yogurt and skyr can promote satiety, potentially aiding in weight control.
- Bone Health: As a dairy product, yogurt is a great source of calcium, which is essential for strong bones and teeth.
Best Practices for Selecting Your Cultured Yogurt
Beyond identifying the right brands, follow these tips to maximize the health benefits of your cultured yogurt purchase:
- Read the sugar content: Many flavored yogurts are loaded with added sugar. For the healthiest option, choose plain or unsweetened varieties and add your own fresh fruit or a drizzle of honey.
- Choose the right type: Greek yogurt and skyr offer a higher protein content, while kefir provides a wider diversity of probiotic strains.
- Consider freshness: Since the number of live bacteria decreases over time, consuming the product well before its expiration date can help maximize the amount of active cultures ingested.
- Watch for heat treatment: Be cautious with products like frozen yogurt or those that seem shelf-stable, as they are less likely to contain live cultures.
Conclusion
Understanding what brands are cultured yogurt and how to identify them is key to reaping the full digestive and immune-supporting benefits of this versatile food. While all yogurt begins with a culture, the presence of active, live cultures is what truly matters for probiotic benefits. By seeking out the NYA's seal or reading ingredient labels for specific bacterial strains, you can confidently choose brands like Chobani, Fage, Siggi's, and Activia. Choosing plain, low-sugar options and consuming them fresh ensures you're getting the most out of your purchase.
