Syntol is a spore-based probiotic enzyme formula. Probiotic spores can survive harsh digestive acidity and heat intact. This therapeutic daily probiotic formula supports microbiome balance, with a gentle enzymatic yeast cleanse.

Syntol® Supports


How it Works

Syntol contains 13.6 billion colony forming units (CFUs) of various non-competing strains of probiotic bacteria per dose. One of these strains is the potent B. subtilis, a spore forming bacteria. Spore germination is a dependable means of delivering healthy flora to the intestine in less than ideal conditions.

The Impact

Recent studies on B. subtilis showed that participants that received the B. subtilis were less likely to develop occasional gas and nausea while the control group was more likely to experience the same. The B. subtilis group was also less likely to experience occasional constipation and diarrhea compared to control. These results are likely the impact of the powerful strain’s ability to promote a healthy GI tract and support normal gut functions.

Immune Support

How it Works

Syntol's powerful enzyme and probiotic blend may support a robust immune
system. When common ailments take a toll on your health, Syntol’s
unique combination of probiotics, prebiotics and enzymes may enhance
your immune defenses. The lining of your intestinal tract houses
roughly 70% of your immune system, thus the key to stronger immunity
lies in your gut.

The Impact

Syntol provides excellent immune support for the following reasons:

  • Probiotics are known to be our first line of immune defense.
  • Creates an intestinal barrier against unwanted pathogens.
  • Supports the production of antibodies.
  • Naturally produces vitamins and minerals vital for healthy immune function.

Healthy Yeast Levels

How it Works

Syntol is one of the only products to offer a gentle yeast cleanse.
In addition to a powerful blend of prebiotics and probiotics, Syntol
also contains a blend of enzymes that provide a thorough intestinal

The Impact

The enzymes work together to support normal yeast levels without
experiencing occasional discomfort known as "die-off".

Mood Enhancement

How it Works

Probiotics positively impact the gut-brain axis (GBA), influencing the delicate connection between our gut and brain. By stimulating tryptophan production, a precursor to serotonin, the feel-good neurotransmitter, probiotics regulate stress, alleviate depressive symptoms, and enhance mood. Probiotics residing in our microbiome contribute to 95% of our body's serotonin, stabilizing appetite, sleep, digestion, and overall well-being. They combat bacterial imbalance, preventing anxiety and irritability, while also improving learning, memory, and mood.

The Impact

Syntol was specifically formulated with eight different types of probiotics that support a healthy intestinal environment, targeting both brain function and digestive activity. This scientifically supported supplement also contains a prebiotic fiber that nourishes good bacteria (probiotics) and promotes their growth.


Too much of a good thing isn’t always a good thing. This is especially true when it comes to candida, a form of yeast that, in moderation, helps with digestion and nutrient absorption. But when it starts overproducing, candida releases by-products into the body. This can lead to occasional:

  • Bloating
  • Gas
  • Fatigue
  • Immune malfunction

There are many factors that can lead to candida and intestinal imbalance. Smoking or drinking, poor nutrition, and high stress are all known contributors.

The good news is you don’t have to suffer any longer. Syntol, a scientifically formulated combination of enzymes, probiotics and prebiotics, is your best choice for supporting healthy yeast levels.

Superior spore forming bacteria survive the harshest environments. Superior strength, bacterial balance, yeast cleanse, and enzymatic gastrointestinal formula.

B. subtilis

Bacillus subtilis is a spore forming bacteria that supports the proliferation of beneficial bacteria and can crowd out other organisms within the gut.

L. helveticus

Lactobacillus helveticus is a probiotic that stimulates the immune and digestive system.

S. boulardii

Saccharomyces boulardii is a non-systemic and non-pathogenic yeast originally found in the skins of the lychee and mangosteen fruits. This yeast is an important probiotic that can help to recolonize and sustain flora in the large and small intestine with its ability to control various forms of diarrhea.

L. acidophilus

Lactobacillus acidophilus is healthy bacteria that produces hydrogen peroxide, lactic acid, and other substances that create an acidic, unfriendly environment for harmful organisms.

L. rhamnosus

Lactobacillus rhamnosus is a lactic acid-producing bacterial strain that is known for its ability to survive in highly acidic conditions of the stomach as well as the intestines.

L. plantarum

Lactobacillus plantarum is a lactic acid-producing bacteria that prevents harmful bacteria from attaching to the mucosal lining and competes for the nutrients the bad bacteria need to survive.

L. lactis

Lactococcus lactis is gram-positive bacteria that ferments milk sugar to lactic acid and adds synergistic support to the probiotic blend as a whole.

B. bifidum

Bifidobacterium bifidum naturally inhabits the colon and vagina, and is a very potent probiotic for the balance of microflora in the intestines.


IMO is a natural, non-GMO prebiotic fiber, providing low calorie and soluble prebiotic fiber for human digestive health. It’s also sugar and gluten-free. When IMO enters the large intestine, it is fermented by indigenous bacteria, providing fertilization of beneficial microflora. It has been clinically shown to greatly increase the number of indigenous bacteria in the digestive tract. In addition to being Kosher and Halal, our IMO products are generally recognized as safe by the FDA and approved by Health Canada. Clinical studies have shown IMO to cause the least flatulence in comparison to inulin and fructo-oligosaccharide (FOS).

Digestive Yeast Cleanse

Syntol uses the extremely potent blend of protease (protein digesting), cellulase and hemicellulase (cellulose digesting), glucoamylase and amylase (breaks down sugars), and serrapeptase. These enzymes strip away the candida's protective protein shell and begin digesting its cellular infrastructure.

Syntol contains a powerful intestinal cleanse to assist in the removal of dead cells and other unwanted proteins from the body. This protects the body from experiencing detox symptoms caused by toxins typically given off from the elimination of yeast.

Suggested Use

Directions: Take Syntol with eight ounces of water on an empty stomach. Start with one to two capsules per day and increase by one to two per day until you reach your desired daily dosage. Larger daily doses may be split into two to three divided doses. For best results, please refer to the guide below.

Maintenance: Two to four capsules per day.

Increased support: Six capsules per day.

Therapeutic: Nine to 12 capsules per day.

Warning: Do not take this product without the consent of your physician if you are currently taking anti-coagulants or if you are pregnant or nursing.

Why Syntol?

Syntol contains 13.6 billion colony forming units (CFUs) of complementary microflora and spore-germinating probiotics per dose. To stimulate the growth and activity of the probiotics, IMO, a non-digestible fiber derived from non-GMO tapioca, has been added as a prebiotic. In addition to beneficial microflora, Syntol also contains a powerful enzyme blend designed to clear yeast and other unwanted debris out of the intestinal tract, making Syntol superior to competing yeast cleanses on the market.
Syntol is a class-leading synbiotic, containing prebiotics, probiotics, and enzymes all in one capsule.

How does Syntol work?

Syntol uses spore germination technology, a revolutionary new process that delivers probiotic spores rather than living bacteria. Probiotic spores are dormant life forms that protect the bacteria from acidic conditions, as well as extreme heat and cold. These spores, along with the potent probiotics, attach themselves to the inside of the intestinal mucosa and begin to germinate, allowing for complete microflora colonization. In addition, the enzyme yeast cleanse will help to break down any dead fungus or toxic materials remaining in the intestinal tract, allowing for a complete eradication of unwanted debris.

Does Syntol require refrigeration?

Refrigerating Syntol is not necessary during its normal shelf-life. The advanced spore germination technology and freeze-dried bacterial strains allow for a shelf stable product. However, it is important to store probiotics in a cool and dry place. Refrigeration will certainly not hurt the product and can prolong shelf stability if you believe that you may be approaching the product’s shelf-date.

What are probiotics?

Probiotics are medically referred to as a group of friendly bacteria or microflora. Probiotic bacteria favorably alter the intestinal microflora balance, inhibit the growth of harmful bacteria, promote good digestion, boost immune function, and increase resistance to infection. People with flourishing intestinal colonies of beneficial bacteria have extremely strong immune systems.

What is Syntol?

Syntol is a powerful combination of non-competing probiotics and prebiotics that are capable of creating an extremely unfriendly environment for yeast colonies and supporting a balanced digestive tract. In addition, Syntol also contains a powerful enzyme blend that is capable of removing dead cells and toxins from the body without the undesirable symptoms often associated with probiotic and digestive cleansing formulas.

What are spores?

Syntol uses spore germination technology, a revolutionary new process that delivers probiotic spores rather than living bacteria. Probiotic spores are dormant life forms that protect the bacteria from acidic conditions, as well as extreme heat and cold. These spores attach themselves to the inside of the intestinal mucosa and begin to germinate, supporting a healthy microbiome.

Can I use Syntol if I am taking antibiotics?

Some doctors feel it is best to wait until an antibiotic regimen is over before taking a probiotic supplement, however there is no evidence that probiotic supplementation is dangerous or will somehow negatively impact the efficacy of the prescription. Opinions do vary, and some doctors will actually encourage their patients to take probiotics while on antibiotics. For this reason, it’s always best to contact your healthcare provider for their direction with these inquiries.

When is the best time to take Syntol?

For best results, take Syntol at least one hour prior to eating and/or two hours after a meal.

Does Syntol contain gluten, dairy, soy, or other allergens?

Syntol does not contain gluten, dairy, soy, tree nuts, peanuts, and shellfish. Syntol is also vegan-friendly.

Best product on the market

I had cancer, I've been taking this product since 2008 It work so well I have doctor friends who now take it.

Q. A.
Excellent product!!! Amazing guest services!!!

So I had a problem with the date on the bottom and mistook it for an expire date when it was actually a manufacturer date. That’s very different. Went to return and left a bad review because I thought the seller was saying non refundable when it was Amazon. The seller got ahold of me right away and took care of all my concerns very quickly. I am very pleased with the product as I have been using it for many years. There really is no substitute!!!

It works

I have a ton of allergies, and this is able to let me eat whatever I want everyday, just make sure you eat something a half hour after and not before and not later or else the stomach gets mad

Day 90

On your first day taking Syntol, you may find it difficult to find time to take it away from meals. It is best to begin Syntol low and slow, so taking 1 dose either first thing in the morning or just before bed would likely be a perfect time to start and then find a good time over the next several days to incorporate a second dose.

After your first week of Syntol, you may notice subtle changes in your digestion as your microbiome begins to balance and normalize.

After 2 weeks of Syntol use, your energy levels after eating should improve as your microbiome is starting to be more efficient and your digestive process is not working so hard after each meal.

After 1 month, your gut continues to work its way towards balance. You may experience more regularity and your immune system is now operating at a higher level.

After 3 months, your micro and mycobiome (fungi) are balanced and supporting optimal digestive and immune health. Your energy has improved, you are able to enjoy eating, and you have less fears of catching that bug going around!
