Syntol for Immune Health

Syntol AMD is a powerful, spore-based probiotic specifically designed to target yeast imbalances, while also providing immune and microbiome support.  Its powerful probiotic formula promotes optimal intestinal conditions for healthy bacterial growth. Syntol is categorized as a synbiotic (pre+pro) yeast cleanse for combining prebiotic, probiotic, and yeast targeting enzymes.

Spore Form Probiotics

Syntol’s dominant immune component is its powerful spore form probiotic blend that can withstand unforgiving intestinal conditions related to pH and/or temperature. Their ability to thrive even after being exposed to the harsh environment of the stomach improves the chances that these healthy bacteria will grow and maintain optimum levels of probiotics in the gut. B. subtilis, one of the strongest bacteria in the blend, has shown a very strong ability to support healthy yeast levels [8].  Research consistently shows that probiotics promote healthy digestive function by binding to certain organisms (e.g., yeast) in the intestines and decreasing their access to the body through the bloodstream [9, 10]. Consequently B. subtilis can indirectly support the immune system by reducing its workload.

Another possible mechanism for the benefits of Syntol’s spore form blend is improved gut barrier function. This appears to promote immune health by disrupting the circulation and ability of harmful contaminants to pass through the digestive system and into the blood. Consuming this type of probiotic encourages a strong response that primes the immune system.

Systemic Enzymes

Syntol AMD also contains an enzyme-based yeast cleanse formula that supports immune health. More specifically, the enzymes can break down the protective outer layer of yeast as well as their cellular components [5, 6]. Probiotics in the gut generally struggle to thoroughly remove dead cells without the assistance of additional enzymes. In the absence of these digestive enzymes, fermentation may develop and harmful byproducts from dead cells may leak into the bloodstream, thereby putting even more strain on the immune system. By flushing out this waste, the enzymes in Syntol AMD may reduce an otherwise uncomfortable detoxification process.
A prebiotic fiber called Isomalto-oligosaccharide is the third key ingredient in Syntol, which nourishes probiotics. Prebiotics are well-known for their ability to boost the growth of healthy bacteria [7]. Having both prebiotics and probiotics (pre+pro) in the same formula is referred to as a synbiotic. Synbiotic supplements are ideal for discouraging yeast, toxins, or harmful bacteria. This subsequently heightens immune health by opposing harmful invaders from circulation.


In summary, Syntol AMD provides B. subtilis, an exclusive immune-strengthening probiotic, along with other probiotics, prebiotics that ensure optimal probiotic function, and powerful enzymes that digest dead cells to reduce the risk of fermentation and toxic byproduct build up. These benefits equal superior immune support that regular probiotic products fail to offer. Taking Syntol AMD regularly is the key to maintaining an immune system that functions efficiently no matter what type of harmful stimuli the body encounters [1-4].
