Where to Buy L. Reuteri Yogurt (Plus How to Make Your Own)
Shoppers looking to buy L. reuteri yogurt have two realistic paths: a ready-made product shipped to the door, or a starter culture used to ferment a batch at home. Zoguri sells a ready-to-eat L. reuteri yogurt supplement that ships cold nationwide, and a few branded yogurts, including BioGaia Protectis, contain the same probiotic strain on store shelves and online. For a larger and cheaper supply, companies such as Cultured Food Life, Luvele and Cutting Edge Cultures sell L. reuteri starter cultures that turn a liter of milk into homemade yogurt after a 36-hour ferment at 100 degrees Fahrenheit. The sections below cover pricing, sourcing and the exact steps for making a batch.
Where to Buy Ready-Made L. Reuteri Yogurt
Zoguri is the main ready-to-eat L. reuteri yogurt sold in the United States, available exclusively through zoguri.com with cold shipping to every state. The company describes it as America’s first ready-to-eat L. reuteri yogurt supplement, built on two keystone strains of the bacteria alongside the traditional yogurt cultures L. bulgaricus and S. thermophilus.
A daily serving is 2 tablespoons, and Zoguri prices it as costing less than a daily coffee shop latte, with 15% off for anyone who signs up for a monthly subscription as of September 2026. Every batch is DNA-verified for strain and bacterial count, and the company backs orders with a 90-day money-back guarantee.
One advantage Zoguri highlights is survivability through digestion: the company attributes this to what it calls dairy matrix protection, arguing that the yogurt format shields live cultures better than a plain capsule would. Shoppers comparing options should keep in mind that Zoguri is the only nationally shipped, ready-to-eat L. reuteri yogurt product documented in this research; the alternatives below either sell a different type of product or ship it as a starter culture rather than a finished yogurt.
Shoppers interested in exploring more options can browse a variety of L. Reuteri Yogurt choices online, which may help compare availability and formats beyond the single nationally shipped product mentioned above.
An L. reuteri yogurt starter culture is used to make yogurt at home rather than eaten as a finished yogurt. It is a different format from a ready-to-eat product, so choosing a starter means taking on the preparation yourself. That distinction matters if you want yogurt you can open and eat, rather than cultures to begin a batch. Check the preparation instructions before deciding whether making your own fits your routine.
Look for a label that names L. reuteri and clearly identifies the product as a yogurt starter culture.

Which Yogurt Brands Contain L. Reuteri
BioGaia Protectis Yogurt is the best-known branded yogurt built specifically around L. reuteri, using the clinically studied DSM 17938 strain. It is sold on Amazon, through the official BioGaia website, and via retailers such as Naturitas, which makes it one of the more accessible branded options for US and European shoppers alike.
BioGaia Protectis Yogurt gives you a yogurt to eat when you want L. reuteri in your diet. The strain name matters more than the word probiotic alone, since other probiotic yogurts may contain different bacteria. Checking the ingredient panel helps you distinguish L. reuteri yogurt from those alternatives. If you are pregnant or nursing, check with your doctor before starting a new probiotic regimen.

Several related formulations use the same strain family, including BioGaia’s Protectis MUM for pregnant women, Immune Active and Gastrus. Miyoko’s Probiotic Yogurt is a smaller, artisanal option that also lists L. reuteri strains on its label, and several European and Scandinavian yogurt brands license those same strains directly from BioGaia, though which countries carry them varies by market.
Reading the label carefully matters here. Not every yogurt marketed as probiotic contains L. reuteri specifically; many rely on other strains such as Lactobacillus acidophilus or Bifidobacterium instead, which do not have the same research behind them for this particular species. A shopper who wants confirmed L. reuteri should look for the strain name, not just the word probiotic, on the ingredient panel, and pregnant or nursing shoppers should check with a doctor before starting any new probiotic regimen.
Where to Buy L. Reuteri Starter Cultures for Home Fermentation
Three companies sell dedicated L. reuteri starter cultures for home fermentation: Cultured Food Life, Luvele and Cutting Edge Cultures. Each ships a sachet-based starter built on the LR007 strain of Lactobacillus reuteri, paired with non-GMO FOS (fructooligosaccharides); the cultures themselves are vegan, dairy-free and non-GMO even though the finished yogurt is typically made with dairy milk.
Cultured Food Life sells its LR Superfood Yogurt Starter for $26.99, with a 10% discount for Biotic Pro members, directly through its online store. Each package holds four sachets, and each sachet makes up to five one-liter batches, for 20 batches total per package.
Luvele US prices the same style of starter at $29.95 for four sachets, though each Luvele sachet is rated for up to two liters, so a package also yields about 20 batches; Luvele sells through Luvele.com and Luvele.ca and is an authorized retailer of Cutting Edge Cultures products.
Cutting Edge Cultures also sells its own Yogurt PLUS starter, a multi-strain blend that includes L. reuteri, for $24.95 per four-sachet package, though each sachet covers only two liters for eight batches total.
| Brand | Sachets per Package | Batches per Sachet | Total Batches | Price | Strain | Vegan |
|---|---|---|---|---|---|---|
| Cultured Food Life LR Superfood | 4 | 5 (1 liter each) | 20 | $26.99 | LR007 | Yes |
| Luvele LR Superfood | 4 | 2 (2 liters each) | 20 | $29.95 | LR007 | Yes |
| Cutting Edge Cultures Yogurt PLUS | 4 | 2 (2 liters each) | 8 | $24.95 | Multi-strain blend with L. reuteri | Yes |
Both Cultured Food Life and Luvele require a separate purchase of prebiotic fiber, typically inulin or an FOS powder such as Prebio Plus, at about 2 tablespoons per batch; without it, the culture will not ferment properly. Starter cultures are also available through Amazon under the Cutting Edge Cultures brand, in addition to the direct-to-consumer stores.
How Much Does L. Reuteri Yogurt Cost
A month of ready-made Zoguri runs about $30 to $40 on a subscription, delivering roughly 15 servings at the recommended 2 tablespoons a day. Starter cultures cost more upfront, $26.99 to $40 depending on brand and whether prebiotic fiber is bundled in, but each batch afterward drops to roughly $2 to $3 per liter, which typically yields four to five servings.
| Option | Initial Cost | Per-Batch Cost | Servings per Batch | Best For |
|---|---|---|---|---|
| Zoguri (ready-made) | $30 to $40 a month subscription | About $30 a month | About 15 servings (2 tablespoons daily) | Convenience, no equipment needed |
| Cultured Food Life starter plus Prebio Plus | About $35 to $40 (starter $26.99 plus prebiotic fiber) | About $2 to $3 per liter batch after the first purchase | 4 to 5 servings per liter | Budget-conscious, bulk production |
| Luvele starter plus prebiotic | About $40 to $45 initial | About $2 to $3 per liter batch | 4 to 5 servings per liter | Budget-conscious, bulk production |
The table shows the tradeoff clearly. Zoguri costs more per month but needs no equipment and no waiting, while a starter culture costs less over time and rewards anyone willing to run a 36-hour ferment and manage their own supply of prebiotic fiber. Reculturing lowers the ongoing cost further, since a finished batch can seed several more rounds before a household needs to buy a new sachet.
How to Make 36-Hour L. Reuteri Yogurt at Home
Cultured Food Life recommends 97-100 degrees Fahrenheit, while Revolution Fermentation uses 35-37 degrees Celsius, or 95-100 degrees Fahrenheit.
Ingredients and Equipment for One Batch
One Revolution Fermentation batch uses 1 liter of whole cow’s milk without additives, one sachet of starter culture, and 2 tablespoons of prebiotic fiber. You also need a yogurt maker or fermentation device with stable low-temperature control, clean glass jars with lids, a saucepan, thermometer, whisk or silicone spatula, and measuring spoons. A dedicated yogurt maker can provide the steady temperature needed for a long ferment.
Step-by-Step Instructions
- Step 1: Warm the milk to the temperature your starter culture’s instructions specify, then let it cool to the correct inoculation temperature before adding anything else.
- Step 2: Mix in the starter culture sachet thoroughly so it disperses evenly through the milk, then stir in the 2 tablespoons of prebiotic fiber.
- Step 3: Transfer the mixture into clean glass jars and place them in the yogurt maker or other fermentation device, set to the temperature specified by the starter maker.
- Step 4: Let the jars sit undisturbed for the full 36 hours; temperature instability or disturbance can contribute to separation.
- Step 5: Check for a tangy smell and a set texture, then refrigerate the jars for at least 4 hours before eating.
Revolution Fermentation lists a serving size of about 1/2 cup and advises starting with small tablespoons to assess tolerance. Storage directions vary by recipe: Revolution Fermentation says its yogurt can be refrigerated for up to 4 weeks, while Real Reuteri advises consuming its version within several days. Follow the directions for the starter and recipe you use.
Choosing the Right Milk
Milk choice affects how well the first batch sets. Cultured Food Life recommends 1 quart of dairy half-and-half for a first batch, or 2 cups of dairy half-and-half mixed with 2 cups of 2% or whole dairy milk. Its FAQ specifies ultra-pasteurized dairy, or milk heated to 195 degrees Fahrenheit or 90 degrees Celsius for 10 minutes and then cooled.
Revolution Fermentation instead calls for whole cow’s milk and says goat’s milk can produce thinner yogurt. Whole milk is also generally a good choice for a thicker, creamier result.
Reusing a Batch as the Next Starter
Once a first batch is finished, 2 tablespoons from it can be used as starter for the next batch with fresh prebiotic fiber. Revolution Fermentation says batches may be recultured multiple times while they remain thick and tart, then replaced with a new sachet if results decline. Cultured Food Life recommends fresh starter if a batch becomes old or stringy.
What to Do if Your L. Reuteri Yogurt Doesn’t Set Right
Separation, a slimy texture and a strong sour taste are the three most common complaints about a first batch of L. reuteri yogurt, and none of them mean the ferment failed. The table below breaks down what causes each issue and the fix that sources recommend.
| Issue | Likely Cause | What to Do |
|---|---|---|
| Curds and whey separate | Normal sign of active fermentation | Stir the whey back in, or drink it on its own; both are safe and still carry probiotics |
| Slimy texture | A strong, active culture, not spoilage | Stir well before refrigerating to smooth out the texture |
| Strong or sour taste | Common in early batches, or too much prebiotic fiber | Use the batch as a starter for the next round, or cut Prebio Plus from 2 tablespoons to 1 |
| Thin, runny yogurt | Weak starter, temperature drift, or low-fat milk | Confirm the incubator holds a steady 100 degrees Fahrenheit and switch to whole milk or half and half |
| Over-fermentation | Jars left too long past the 36-hour mark | Set a timer and remove the jars promptly once 36 hours is up |
A dependable, steady-temperature setup improves results more reliably than changing the recipe itself, since most first-batch problems trace back to inconsistent heat rather than the ingredients.

Frequently Asked Questions
Is L. Reuteri Yogurt Sold in Grocery Stores?
L. reuteri yogurt is not identified as available at mainstream US grocery chains such as Whole Foods or Sprouts. Buying directly online, whether from Zoguri, BioGaia’s official channels, or a starter culture maker, is the most consistently documented way to get it right now.
Do I Need Special Equipment to Make L. Reuteri Yogurt?
Yes, because the 36-hour ferment needs a steady 100 degrees Fahrenheit for a day and a half, which a normal kitchen counter cannot hold on its own. A yogurt maker, an Instant Pot with a manual temperature setting, a sous vide device or a dehydrator all work, as long as they hold that exact temperature without drifting.
Should I Check with a Doctor Before Trying L. Reuteri Yogurt?
Anyone who is pregnant, nursing, immunocompromised, or managing a digestive condition should check with a doctor before adding a new probiotic like L. reuteri to their diet. This applies whether the product is a ready-made yogurt, a branded supplement or a homemade batch, since all of them introduce a concentrated new bacterial strain to the gut.
Are L. Reuteri Starter Cultures Vegan?
The starter cultures themselves are vegan, dairy-free and non-GMO, since they contain only the L. reuteri strain and a prebiotic fiber such as FOS. Home recipes are typically not vegan, though, because the yogurt itself is fermented in dairy milk such as whole milk or half and half rather than a plant-based base.
What Makes L. Reuteri Yogurt Different from Regular Yogurt?
Regular yogurt is fermented for about 8 hours with Lactobacillus bulgaricus and Streptococcus thermophilus, while L. reuteri yogurt ferments for 36 hours at 100 degrees Fahrenheit specifically to multiply that strain. A finished 36-hour batch can contain over 135 billion active probiotic bacteria per 250 milliliters, a far higher count than a standard store-bought yogurt provides.
A month-to-month decision comes down to convenience versus cost: Zoguri and BioGaia deliver a finished product with no equipment, while a starter culture and the 36-hour method reward anyone willing to run a longer ferment for a lower price per serving. Either path documented here delivers a confirmed L. reuteri strain, which is the detail worth checking on any label before buying.
