Drink probiotic sodas and nurture your microbiome!
Nothing pleases me more than to introduce you to our Kefir Soda Starter made by Cutting Edge Cultures. I've been making kefir soda using culture package for over twenty-one years. For many many years, I have wanted to make my own culture with good yeasts and bacteria that would have more benefits. After testing and experimenting with different good bacteria and yeasts, I finally have made my own product with enhanced benefits that is super easy to make and has many health benefits. It is also really bubbly, so much that you have to pop the top every day, less it overflows or explodes!
Change The Inner Eco System
Our Kefir Soda Starter is one of the best ways to have your soda and fizz without all the harmful additives and unhealthy sugars and sugar replacements that are hard on your body. This soda contains beneficial bacteria strains and good yeasts to help you make a fun bubbly, and healthy replacement for soda! Each package can make you dozens of liters of kefir soda if you make it often.
The strains and yeasts metabolize the natural sugar found in fruit juice or coconut water, resulting in an effervescent drink that is loaded with probiotics.
Pop The Top Every Day
Make sure you use bottles such as Grolsch or thick glass bottles made for beer or brewing. Old GT's synergy kombucha bottles will work too. Bottles bought at craft stores can explode.
32-ounce Amber Bottles
Then while fermenting, check them every day by slowly popping the top. After fermentation and they're in the fridge, pop the top every day to release the pressure as well. These can get a lot of pressure and are super bubbly. You'll want to check them often to slowly release the pressure.
Good Bacteria and Yeasts
This culture starter has many good bacteria that help to colonize and improve your microbiome but it also has one of my favorite probiotic yeasts. Saccharomyces Boulardii is one of the most researched probiotics and is absent from the natural gut since it is a transient yeast that passes through the intestines after ingestion. If taken often it provides a steady stream in the colon within three days and is cleared from the stools two to five days later. It does not attach to the mucosal cell lining but works its magic on you as it moves through the gastrointestinal tract. When S. boulardii is present, it inhibits toxins from binding to intestinal receptors and steals the metabolites it needs to survive. It's a powerhouse and cannot be killed by antibiotics.
If you live in the USA, you can order directly from my store. I keep these cultures refrigerated to ensure that they stay alive & fresh while they are waiting for you to adopt them.
Cutting Edge Cultures also has them for sale directly on their website.
You can also get them from Amazon.com, just know that I don't think that the Amazon warehouse keeps them refrigerated.
Refrigeration is always recommended! These cultures will last 24 months in the fridge, even longer in the freezer, but only about two weeks at room temperature.
Research On Probiotics in Kefir Soda Starter
Fermented foods play a vital role in nurturing your microbiome & health
We hand-picked the bacteria and good yeast for this starter. Check out all the different benefits.
Leuconostoc mesenteroides and Lactobacillus delbrueckii are both in kefir grains and are potent microbes. Leuconostoc mesenteroides is responsible for initiating the lactic acid fermentation of dairy products, sauerkrauts, and vegetables. It has been reported that Leuconostoc mesenteroides can inhibit the growth of pathogens and also prevent Avian influenza and H1N1. [1,2]
Lactobacillus delbrueckii can help the body break down food, absorb nutrients, and fight off bad organisms that might cause disease. It has been used to aid digestion, prevent diarrhea, and relieve symptoms of irritable bowel syndrome. L. bulgaricus and L. lactis, which are also powerful strains and well-studied probiotic species, were shown to have highly similar DNA to L. delbrueckii, and have since been considered to be subspecies of L. delbrueckii 
Bifidium Longum has long been regarded as one of the most beneficial members of the human gut microbiome. Lower levels of this beneficial bacteria have been shown in obese and diabetic individuals and in individuals taking antibiotics. Those suffering from irritable bowel syndrome or inflammatory bowel disease have also shown lower levels of bifidobacteria as well. Bifidium longum also helps work on anxiety- and depression-like behaviors. B. longum can inhibit inflammation by regulating the balance of the immune system. It can improve intestinal barrier function. 
Saccharomyces boulardii is my favorite probiotic yeast. Not only will it make this soda super bubbly it also has a lot of health benefits. Not only can it not be killed by antibiotics it has helped with health problems.
They have done over 53 randomized controlled clinical trials, encompassing 8475 subjects, that investigated the safety and efficacy of S. boulardii. The studies were done in pediatric and adult patients in which they found it had an 81% efficacy rating. It is now used to treat C. diff, acute diarrhea, antibiotic-associated diarrhea, some parasitic forms of diarrhea, and other gastrointestinal disorders. [7,8]
S. boulardii is unrelated to the yeast Candida albicans and other Candida species. When you have Candida proliferating, it will decrease the acidity of the gut making it susceptible to harmful bacteria and yeasts. S. boulardii exerts the opposite effect producing lactic and other acids known to inhibit potentially harmful Candida yeast species. 
S. boulardii is absent from the natural gut since it is a transient yeast that passes through the intestines after ingestion. If taken every day, it provides a steady stream in the colon within three days and is cleared from the stools two to five days later.[10,11] It does not attach to the mucosal cell lining, but works its magic on you as it moves through the gastrointestinal tract.
When S. boulardii is present, it inhibits toxins from binding to intestinal receptors and steals the metabolites it needs to survive. Thus many pathogens pass out of the body unable to survive in the presence of this powerful probiotic. They even found that other pathogen strains like E. coli, Salmonella typhimurium, and S. typhi adhere to the surface of S. boulardii, thus preventing them from attaching to the mucosal lining and passing through the body rendering them harmless.
