Deep Dive: What Gold Faro Enzyme Does and What the Research Shows
Digestive enzymes are one of those topics that genuinely reward a closer look. Amylase sits at the center of how your body processes carbohydrates, and clinical research is helping clarify what enzyme supplementation can and cannot do. Understanding the underlying science is a strong foundation for evaluating any enzyme product on the market.

The Science of Amylase and What It Does in Your Gut
Amylase is a hydrolase enzyme that breaks starch down into maltose and glucose. Your body produces it in two primary locations: the salivary glands in your mouth and the pancreas. These two sources work sequentially to move carbohydrate digestion from chewing through to the small intestine.
Salivary amylase operates at optimal activity between pH 6.5 and 7.5, handling approximately 30 to 40 percent of starch before food reaches the stomach. Once food enters the stomach, the acid environment (pH 1 to 3 on an empty stomach) dramatically reduces salivary amylase activity. Pancreatic amylase then takes over in the small intestine, where pH rises again to the 6 to 8 range that supports enzyme function.
Exogenous, or supplemental, amylase is derived from microbial or plant sources rather than the human body. Microbial-origin enzymes, including those produced by lactic acid bacteria (LAB) fermentation, tend to maintain activity across a wider pH range than animal-derived enzymes [8]. This property matters because an enzyme that cannot survive the acidic stomach environment will have limited effect before reaching the small intestine.
Lactic acid bacteria generate amylase, protease, and phytase naturally during fermentation processes. This enzymatic activity during fermentation also improves mineral bioavailability and produces prebiotic oligosaccharides as byproducts [8]. Understanding these co-produced compounds helps explain why fermentation-derived enzyme products are more complex in their composition than isolated enzyme extracts.
The practical relevance of enzyme supplementation becomes clearest in the context of functional digestive complaints. Functional dyspepsia, defined as upper abdominal discomfort without an identifiable structural cause, is associated with reduced endogenous enzyme output. External enzyme support is one strategy researchers have examined to address this gap.

What Clinical Trials Have Found on Digestive Enzyme Supplementation
The clinical evidence for digestive enzyme supplementation has matured considerably over the past decade. Two lines of evidence stand out: trials testing amylase-containing blends for gut symptoms, and microbiome studies on probiotic amylase preparations.
A randomized, double-blind, placebo-controlled trial published in Beneficial Microbes tested a probiotic amylase blend specifically for gastrointestinal symptom reduction [1]. Sixty adults completed the six-week trial. The amylase group showed approximately 60 percent reduction in Gastrointestinal Symptom Rating Scale (GSRS) scores from baseline. The placebo group showed roughly 25 percent reduction. The effect size for overall symptom reduction was d = 0.72, which is considered a moderate-to-large effect. Bloating showed a Cohen's d of -0.63 and abdominal discomfort d = -0.66, both clinically meaningful improvements [1].
The same research group published a companion RCT in Life (MDPI) examining what that amylase blend was doing to the gut microbiome [2]. Among 51 participants, Saccharomyces cerevisiae increased approximately 200-fold in the treatment group. Bacillus thuringiensis decreased approximately 150-fold, and Macrococcus caseolyticus decreased approximately 175-fold. These changes suggest a meaningful restructuring of the microbial environment, not merely symptomatic relief at the surface level [2].
A separate multi-enzyme RCT published in Biomedicine and Pharmacotherapy enrolled 120 patients with functional dyspepsia and ran for eight weeks [3]. The treatment group received a multi-enzyme blend at 200 mg per day. Versus placebo, participants improved significantly on the NDI-SF quality of life scale, VAS pain scores, and Pittsburgh Sleep Quality Index (PSQI). No serious adverse events were recorded in either group [3].
LAB fermentation has also been studied for its role in gluten degradation, relevant to any fermented enzyme product derived from wheat-based substrates. One experimental study found that LAB and fungal protease combinations reduced residual gluten from approximately 70,000 ppm to 12 ppm, exceeding 99.9 percent reduction. T-cell immunogenicity was abolished in that model [4]. A related study found that two lactic acid bacteria strains together reduced gliadin content by approximately 76,100 ppm. The immune-reactive 33-mer gliadin fragment was cut by 56.6 percent [5].
The clinical picture across these studies points consistently toward fermented amylase preparations producing real effects on both symptoms and microbiome composition. Effect sizes are moderate to large where reported, and serious adverse events are notably absent across the trial literature.
Introducing Gold Faro Enzyme: How the Product Connects to the Science
Gold Faro Enzyme is a fermented enzyme food developed by Dr.Blet. It is made from emmer wheat (known in Italian as farro, botanically Triticum dicoccum) along with 14 domestic grains, fermented together using lactic acid bacteria. The amylase science explored in the sections above directly informs how this product is designed.
Emmer wheat brings a distinct nutritional profile to the fermentation substrate. Compared to modern wheat, T. dicoccum contains higher protein levels, greater dietary fiber, and elevated bioactive phenolic compounds, with slow-digesting starch characteristics that have prebiotic-like properties [7]. Sourdough fermentation of T. dicoccum triples total phenolic content and increases flavonoid levels approximately 23-fold. Antioxidant activity rises 2.7 to 7.3 times, while inflammatory markers including IL-8, COX-2, and ICAM-1 are suppressed [6].
LAB fermentation of the multi-grain base also reduces phytic acid, an antinutritional compound that binds minerals and limits their absorption. Fermentation can cut phytic acid content by up to 73 percent, correspondingly increasing the bioavailability of iron, zinc, magnesium, and calcium [9]. The fermentation process thus changes the nutritional character of the substrate in ways that extend beyond enzyme output alone.
The resulting product contains amylase as its primary enzymatic activity, with a supporting protease fraction. This compositional profile aligns with the amylase-focused RCT literature where the most consistent symptom benefits have been documented [1, 2]. Gold Faro Enzyme carries quality certifications from SGS, BRCS, HACCP, EU Organic, and KOSHER, which reflect manufacturing and sourcing standards rather than clinical efficacy claims.
One important note: the product contains emmer wheat and soy fermentation powder. Anyone with wheat allergy, celiac disease, or soy allergy should consult a healthcare provider before use. Fermentation reduces but does not eliminate gluten, and people with celiac disease should not assume fermented wheat products are safe without professional guidance.
Safety, Dosing Context, and What the Evidence Cannot Tell Us
Understanding what the research supports is as important as knowing what it shows. Over-the-counter digestive enzyme supplements are generally considered safe at recommended doses, with rare serious adverse events recorded across the literature [10]. Mild gastrointestinal discomfort at high doses is the most commonly documented side effect, and it typically resolves with dose adjustment [10].
The clinical trial evidence reviewed above establishes meaningful symptom improvements at the group level. Group-level statistics do not predict individual outcomes with certainty. Enzyme activity measured under laboratory conditions (standardized temperature, controlled pH) differs from the variable environment of a living digestive tract. Results across individuals will vary based on baseline digestive function, dietary patterns, gut microbiome composition, and other factors.
Microbial-origin enzymes tolerate a broader pH range than animal-sourced enzymes [8]. This is one reason fermented microbial preparations are considered a favorable format for gastric acid transit. That said, published in-vivo activity data for any specific commercial enzyme product should be sought from independent peer-reviewed sources rather than proprietary measurements.
Safety note: Digestive enzyme supplements are not appropriate substitutes for medical treatment of diagnosed digestive conditions. If you have diagnosed pancreatic insufficiency, inflammatory bowel disease, celiac disease, or another gastrointestinal condition, consult a gastroenterologist before using any enzyme supplement. Starting at the lowest recommended dose and monitoring for tolerance over the first two weeks is a prudent approach for anyone new to enzyme supplementation.
The question of long-term use safety is one where the literature is less complete. The Mayo Clinic Proceedings review noted that serious adverse events are rare, but acknowledged that long-term safety monitoring for OTC enzyme supplements remains limited [10]. Users considering extended supplementation should discuss this with their healthcare provider.
Frequently Asked Questions
Q. What is amylase and why does it matter for digestion?
Amylase is the enzyme responsible for breaking down dietary starch into simpler sugars the body can absorb. Your salivary glands and pancreas both produce it naturally. When endogenous amylase output is insufficient, due to age, digestive conditions, or functional dyspepsia, carbohydrate digestion can be incomplete, contributing to bloating, gas, and discomfort. Exogenous amylase supplementation is one approach studied to support this process [1, 3].
Q. Does fermentation affect how digestive enzymes work?
Yes. Lactic acid bacteria produce amylase, protease, and phytase during fermentation, and the fermentation process itself modifies the nutritional and enzymatic character of the substrate. Research shows fermentation can improve mineral bioavailability, reduce antinutritional compounds like phytic acid by up to 73 percent, and alter starch digestibility in ways that may ease the overall digestive load [8, 9].
Q. Is Gold Faro Enzyme suitable for people with gluten sensitivity?
Not without medical guidance. Gold Faro Enzyme is derived from emmer wheat, which contains gluten. Fermentation reduces gluten levels but does not eliminate them. Anyone with celiac disease, wheat allergy, or diagnosed non-celiac gluten sensitivity should consult a healthcare provider before use. Fermented wheat products are not certified gluten-free and carry residual gluten risk [4].
Q. What do the clinical trials on amylase supplementation actually show?
The most directly relevant RCTs found that a probiotic amylase blend reduced total GSRS gastrointestinal symptom scores by approximately 60 percent versus 25 percent for placebo, with moderate-to-large effect sizes for bloating and abdominal discomfort [1]. A companion study documented significant microbiome shifts, including a 200-fold increase in S. cerevisiae [2]. A multi-enzyme RCT in functional dyspepsia patients also showed significant improvements in quality of life and pain scores [3]. These are group-level findings from specific formulations and should be interpreted accordingly.
Q. Are digestive enzyme supplements safe to take long-term?
At recommended doses, OTC digestive enzyme supplements have a generally favorable safety profile, with rare serious adverse events in the published literature [10]. Mild GI discomfort at high doses is the most common issue and typically resolves with dose reduction. Long-term safety data is still limited, and anyone considering extended use should discuss it with a healthcare provider, particularly if they have underlying digestive conditions.
