Syntol - A Probiotic Approach to Skin Health From Within

Syntol is a synbiotic or a prebiotic + probiotic blend with yeast cleanse, enriched with vitamin C and digestive enzymes that offer excellent support for your body’s intestinal microbiome. The formula consists of eight beneficial probiotic strains that reinforce optimal gastrointestinal (GI) function by influencing both nutrient absorption and the intricate connection between the brain and gut.

The digestive tract not only houses healthy bacteria (probiotics) but is also the primary location of nerves that transmit vital signals to the brain [1, 2]. Intestinal irritation or probiotic imbalance can hinder both nutrient absorption and nerve signal transfer to the brain, causing sluggish mental performance [1, 2].

Fortunately, probiotic supplementation strengthens nervous system activity by blocking the growth of harmful invaders that may damage the protective intestinal lining where the vast network of nerves are located [3]. Syntol provides 13.6 billion colony forming units (CFUs) of eight well-researched probiotics that offer unmatched digestive support [4-6]. In addition to promoting healthy digestive and cognitive function, Syntol’s exclusive formulation helps keep yeast levels within a normal range. The carefully chosen blend of nutrients also supports a yeast cleanse if overgrowth occurs.

Syntol Fights Yeast

Yeast can typically be found inside the body in different areas such as the gut, bladder, urinary tract, and vaginal region, as well as on the skin. Candida yeast typically coexist in the gut with other healthy bacteria, where they help the body absorb vitamins and minerals, and even support immune system function [7].

However, certain factors such as eating sugary, processed foods, taking antibiotics, or certain health issues can weaken immune response as well as allow yeast to shift into a fungal form. Uncontrolled fungal overgrowth can rapidly spread, making it harder for the body to maintain probiotic balance or restore immune system function. This type of overgrowth is often associated with fungal issues of the intestinal, vaginal, bladder, and urinary tract [6-11]. Syntol supplementation helps target these types of health problems.

Syntol research shows that individuals with GI problems (e.g., bloating, flatulence, cramping, diarrhea), mood swings, food cravings, and even sleep disturbances due to yeast overgrowth experienced noticeable benefits after taking this supplement for at least 45 days. Blood test results demonstrated substantially lower, and in several cases, the complete cleansing of harmful Candida albicans (yeast) from the blood. This means that Syntol reinforces optimal immune responses to yeast overgrowth by lessening the workload on the immune system.

Additional studies show that taking probiotics regularly promotes healthy digestive function, as the beneficial bacteria bind to destructive invaders (e.g., Candida albicans) in the intestines and minimize their access to the body through the bloodstream [8, 9]. Therefore, probiotics target destructive yeast that may invade other parts of the body, including the vaginal region or urinary tract [8, 10, 11]. One serving of Syntol provides 13.6 billion CFUs of probiotics, which is an ample serving for sustained microbiome balance throughout the body.

Syntol Boosts Skin Health

As yeast are also naturally found on the skin, certain areas that remain moist and warm for too long (e.g., armpits, skin folds) are particularly susceptible to these types of fungal changes. Your skin microbiome, also called skin microbiota, is an ecosystem of bacteria on the skin's surface that guards against invaders (e.g., yeast overgrowth) [12]. Unfortunately, a microbiome imbalance can prevent the skin’s ecosystem from combating harmful yeast (fungi) linked to skin irritation, dryness, redness, blemishes, and flare-ups.

Furthermore, an irritated intestinal lining may develop gaps that allow harmful organisms to pass into the bloodstream and travel to the skin’s surface, where they can irritate the skin or lead to acne flare-ups [12]. Additionally, invader overgrowth (yeast) heightens immune system activity when they enter the bloodstream. If the immune system becomes overactive during its attempt to fight the invaders, abnormal inflammatory responses may begin to harm the skin. 

If unhealthy inflammatory responses persist, proteins called cytokines may be released, and rising levels of cytokines are associated with the formation of acne scars [12]. This means that a microbiome imbalance due to yeast overgrowth may initiate a domino effect that leads to skin problems. Probiotics have been shown to enhance skin health in similar ways to digestive, vaginal, and urinary function [13]. According to Kristin Peck CEO of Taut Haute Skin clinic, Syntol has helped her clients reduce common skin complaints including blackheads and even cystic acne.

Research involving people with chronic acne who were given a daily supplement containing certain probiotic strains demonstrated dramatic minimization of acne scars [13]. Accordingly, by maintaining sufficient levels of probiotics through Syntol supplementation, the blood is cleansed of yeast that can harm the skin without experiencing problems related to die-off, which refers to the release of toxins as yeast die. Imbalances of certain beneficial probiotics can increase instances of rosacea, a dermatological skin condition affecting the face.  Syntol’s probiotics enhance the body’s ability to release detoxing cells that bind to and flush dead yeast and skin inflaming bacteria out of the system before toxins can alter skin health.

An Added Boost of Nutrients

To further enhance skin health by boosting the removal of destructive yeast and harmful bacteria, digestive enzymes that were observed on dead yeast in laboratory settings were also added to the Syntol formulation. These include: serrapeptase and protease to break down proteins; cellulase and hemicellulase to break down fiber; amylase and glucoamylase to break down sugars. The combination of these enzymes destroys the protective, protein-based shell of Candida yeast and the inner components to enhance the cleansing process [14, 15].

Overall, Syntol helps the body naturally target and cleanse harmful yeast that are linked to several problematic health issues from stomach upset, vaginal discomfort, and urinary issues to skin irritation and acne flare-ups.
