What Yogurt Has Lactobacillus Reuteri?
While Lactobacillus reuteri is not a naturally occurring strain in most commercially available yogurts, certain brands and specialized starter cultures are designed to include it; these yogurts are often marketed for their potential probiotic benefits, particularly gut health and immune support.
Understanding Lactobacillus reuteri
Lactobacillus reuteri is a probiotic bacterium naturally found in the human gut, although its presence can vary significantly from person to person. It’s known for its potential health benefits, including improving gut health, boosting the immune system, and even producing antimicrobial substances. Unlike some other common yogurt cultures like Streptococcus thermophilus and Lactobacillus bulgaricus, L. reuteri is not typically used in standard yogurt production.
Therefore, if you’re looking for yogurt with L. reuteri, you’ll need to be proactive in seeking it out. This usually means looking for specific brands or considering making your own yogurt at home with a L. reuteri starter culture.
Benefits of Lactobacillus reuteri Yogurt
Consuming yogurt with L. reuteri may offer a range of potential health benefits:
- Improved Gut Health: L. reuteri can help restore and maintain a healthy balance of gut bacteria.
- Enhanced Immune Function: Studies suggest it can stimulate the immune system and improve its response to pathogens.
- Reduced Inflammation: L. reuteri may help reduce inflammation in the gut and throughout the body.
- Oral Health: Some research indicates it can contribute to better oral hygiene by inhibiting the growth of harmful bacteria in the mouth.
- Skin Health: Emerging evidence suggests a connection between gut health and skin health, and L. reuteri may play a role in improving skin conditions.
These benefits are supported by ongoing research, and while promising, more studies are needed to fully understand the extent of L. reuteri‘s impact.
Finding and Identifying Yogurt Containing L. reuteri
Identifying yogurt with Lactobacillus reuteri requires careful attention to product labels. Here’s what to look for:
- Ingredient List: Check the ingredient list for “Lactobacillus reuteri” or a specific strain designation, such as Lactobacillus reuteri ATCC PTA 6475.
- Probiotic Claims: Some brands will highlight the inclusion of L. reuteri with claims about its probiotic benefits.
- Brand Websites: Visit the manufacturer’s website for more detailed information about the strains used in their yogurt.
- Customer Reviews: Read customer reviews to see if other users have found the yogurt to be effective for their desired purpose.
Be aware that many yogurts advertised as “probiotic” may contain only common yogurt cultures and other probiotic strains, but not L. reuteri. Thoroughly check the label to ensure it’s included.
Making Your Own Lactobacillus reuteri Yogurt
An alternative to searching for commercially available L. reuteri yogurt is to make your own at home. This provides greater control over the ingredients and the specific strains used. Here’s a general overview of the process:
- Obtain a L. reuteri Starter Culture: Purchase a yogurt starter culture specifically containing Lactobacillus reuteri. Reliable sources include specialized probiotic suppliers online.
- Prepare the Milk: Use pasteurized milk (cow’s milk, goat’s milk, or even coconut milk) as the base. Heat the milk to a simmer (around 180°F or 82°C) and then allow it to cool to around 110°F (43°C). This step helps denature milk proteins and create a better environment for the bacteria.
- Inoculate the Milk: Add the L. reuteri starter culture to the cooled milk and stir well to distribute it evenly. Follow the instructions provided with the starter culture, as the amount needed may vary.
- Incubate the Mixture: Maintain the inoculated milk at a consistent temperature of around 100-110°F (38-43°C) for 24-36 hours. A yogurt maker is ideal for this, but you can also use an oven with the light on or a sous vide machine.
- Check for Consistency: After the incubation period, check the yogurt’s consistency. It should have thickened and have a slightly tangy aroma. If it’s not thick enough, continue incubating for a few more hours.
- Refrigerate: Once the yogurt has reached the desired consistency, refrigerate it for at least 2 hours to stop the fermentation process and allow it to set further.
Making your own L. reuteri yogurt requires attention to detail and proper sanitation to ensure a safe and effective product.
Common Mistakes When Making L. reuteri Yogurt
- Incorrect Temperature: Failing to maintain the correct incubation temperature can hinder bacterial growth.
- Contamination: Using unsterilized equipment can introduce unwanted bacteria that compete with the L. reuteri.
- Using Too Much or Too Little Starter: Following the instructions on the starter culture package is crucial.
- Insufficient Incubation Time: Not incubating for long enough can result in thin, watery yogurt.
- Using Ultra-Pasteurized Milk: While possible, some find that ultra-pasteurized milk doesn’t result in as thick of a yogurt.
Considerations Before Consuming L. reuteri Yogurt
Before making L. reuteri yogurt a regular part of your diet, consider these factors:
- Individual Sensitivities: Some individuals may experience mild digestive upset when first introducing L. reuteri. Start with small amounts and gradually increase intake.
- Consult a Healthcare Professional: If you have any underlying health conditions or are taking medications, consult a doctor or registered dietitian before adding L. reuteri to your diet.
- Source of L. reuteri: Ensure the L. reuteri strain used in the yogurt is well-researched and has demonstrated health benefits.
- Storage: Store L. reuteri yogurt properly according to the manufacturer’s instructions to maintain its probiotic potency.
Commercial Yogurt Options
While homemade yogurt is often the best way to guarantee L. reuteri content, some commercial brands do include it. These often come at a higher price point than conventional yogurts. Thoroughly check the labels of any yogurt marketed for probiotic benefits to confirm the presence and strain of L. reuteri. Availability also varies depending on geographical location.
Comparing Commercial Yogurt to Homemade
| Feature | Commercial Yogurt | Homemade Yogurt |

The Future of Lactobacillus reuteri Yogurt
Research into the benefits of Lactobacillus reuteri is ongoing, and it is likely that we will see more yogurts incorporating this probiotic in the future. As consumers become more aware of the importance of gut health, the demand for L. reuteri-containing products is expected to increase, leading to greater availability and potentially lower prices.
The Role of Fermentation
Fermentation is the process that transforms milk into yogurt. Specific bacterial strains, like L. reuteri, are added to milk to convert lactose (milk sugar) into lactic acid. This process not only gives yogurt its characteristic tangy flavor and thick texture, but it also preserves the milk and creates a favorable environment for beneficial bacteria to thrive. The fermentation process is what allows the L. reuteri to grow and multiply, increasing the probiotic benefits of the final product.
