Introduction: Fundamental Concepts of the Microbiome
The human microbiome is the collection of all microorganisms (bacteria, viruses, fungi, and other microbes) that reside in our bodies. Far from being mere passengers, these microscopic beings perform vital functions for our survival, such as digesting food, producing essential vitamins, and protecting against pathogens. A balanced microbiome is synonymous with health, while an imbalance, known as dysbiosis, is associated with numerous chronic conditions. However, the growing popularity of this topic has led to a wave of misinformation and products promising quick fixes without solid scientific backing. Understanding the basic principles is the first step in separating science from fiction.
The Big Difference: Fermented Foods vs. Probiotics
One of the most widespread misconceptions is confusing the role of fermented foods with that of probiotic supplements. While both can be beneficial, their mechanisms of action and their impact on our internal ecosystem are fundamentally different. Understanding this difference is crucial for implementing an effective strategy for rebuilding and maintaining the microbiome.
What are probiotics?
Probiotics are live microorganisms that, when administered in adequate amounts, confer a health benefit on the host. The defining characteristic of a probiotic strain is its ability to colonize, or settle in, the body, becoming a long-term resident of our microbial ecosystem. A prime example is Lactobacillus reuteri, a bacterium that can establish itself and thrive in the small intestine, colon, and even the oral cavity, exerting lasting beneficial effects. Another example is Faecalibacterium prausnitzii, an important resident of the gastrointestinal tract that produces butyric acid, a compound vital for the health of colon cells.
The Role of Fermented Foods
Fermented foods, such as yogurt, kefir, sauerkraut, and kimchi, are rich in microbes, but these microorganisms are generally transient. That is, they don't permanently settle in our digestive tract. Species like Leuconostoc mesenteroides and Pediococcus pentosaceus, common in fermented foods, travel through our digestive system, interact with our resident microbiome, and are then excreted. Despite their transient nature, their contribution is immensely valuable. They are believed to act through a "cross-feeding" mechanism, providing nutrients and metabolites that feed our existing beneficial probiotic bacteria, thereby stimulating their growth and activity. In short: probiotics are the "colonists," while the microbes in fermented foods are the "gift-bearing visitors."
Is More Better? The Dose-Response Principle in Probiotics
One of the least understood areas, even within the scientific community, is the dose-response relationship in probiotic supplementation. What is the minimum amount of microbes needed to observe a clinically significant effect? Is there a saturation point beyond which the benefits no longer increase?
Current evidence suggests that dosage is a critical factor. A remarkable study on the Lactobacillus gasseri BNR17 strain perfectly illustrates this point. Participants who consumed a daily dose of 10 billion Colony Forming Units (CFU) experienced an average reduction of 5 cm in waist circumference. However, the group consuming a dose ten times lower (1 billion CFU) showed no significant effect compared to the placebo. This raises important questions: What would happen with even higher doses, such as 50 or 100 billion CFU? Would the results be amplified?
Most commercial products offer doses that may be insufficient to produce a real change. In contrast, prolonged home fermentation, such as preparing specific yogurts with probiotic strains like Lactobacillus reuteri, can generate massive microbial concentrations, potentially reaching up to 300 billion CFU per serving. This level of dosage is rarely achieved by commercial supplements and could explain why many people report more profound benefits with well-formulated homemade preparations.
Navigating the Market: Myths and Deceptive Marketing Strategies
The probiotic market is saturated with products that use scientific language to promote features that, in practice, may be irrelevant or even counterproductive. It is essential to develop a critical eye to identify these marketing tactics.
Myth 1: Double Encapsulation is Always Superior
Many products boast of using "double encapsulation" or enteric coating technology, promising to protect microbes from stomach acid and release them directly into the colon. While this may be helpful for certain strains intended to act in the large intestine, it's a misleading generalization. Many dysbiosis problems, such as Small Intestinal Bacterial Overgrowth (SIBO), occur precisely in the small intestine. Key strains like Lactobacillus reuteri and Lactobacillus gasseri are naturally resistant to stomach acid and bile salts; they have evolved to survive this journey. Releasing them prematurely or exclusively in the colon could limit their ability to act where they are most needed.
Myth 2: The More Species, the Better
The "more is better" logic applies again to products containing 50, 100, or even more different species. At first glance, it seems like a way to cover all the bases. However, the reality is that by dividing the total CFU dose among so many strains, the amount of each individual species becomes minuscule. It's very likely that the dose of each specific strain is too low to exert any significant biological effect. A carefully formulated product, based on the synergy and collaboration between a limited number of well-studied strains, is often far more effective than a diluted microbial cocktail.
Myth 3: All Included Strains are Safe and Tested
Surprisingly, some companies include microbes in their formulations that haven't been rigorously tested for safety in human consumption. This practice violates guidelines from regulatory agencies like the FDA (U.S. Food and Drug Administration). An informed consumer should always look for products that specify the exact strains (for example, Lactobacillus rhamnosus GG) and that are supported by human safety and efficacy studies.
Frequently Asked Questions about the Microbiome
Why do I feel unwell (bloating, diarrhea, brain fog) after taking probiotics or eating high-fiber foods?
This is a common and often misunderstood experience. The adverse reaction doesn't necessarily mean that probiotics or prebiotic fibers are "bad" for you. In fact, it could be a warning sign of a more serious underlying problem: Small Intestinal Bacterial Overgrowth (SIBO). SIBO occurs when bacteria that normally reside in the colon, such as E. coli or Klebsiella, migrate and colonize the small intestine, where they shouldn't be. Introducing probiotics or prebiotics (which are food for these bacteria) causes excessive fermentation in the wrong place, generating gas and toxins that lead to symptoms like bloating, diarrhea, brain fog, or even skin rashes. The solution isn't to avoid these beneficial foods forever, but rather to diagnose and treat the root cause of the SIBO. Ignoring it can lead to long-term health complications.
Are fermented foods enough to correct a microbiome imbalance?
While fermented foods are an excellent tool for maintaining and nourishing the microbiome through cross-feeding, they may not be sufficient on their own to correct severe dysbiosis or reintroduce specific strains that have been lost. In such cases, targeted supplementation with high-dose probiotics of specific strains, along with a proper diet, is often a more effective strategy.
Conclusion: Towards Intelligent Management of Your Gut Health
Microbiome management is a nuanced discipline that goes far beyond simply taking a probiotic pill. It requires a clear understanding of the difference between colonization and cross-feeding, the critical importance of dosage, and the ability to distinguish between real science and marketing hype. By focusing on evidence-based strategies, such as consuming a variety of fermented foods and using specific probiotics in appropriate doses, you can take control of your gut health in a much more powerful and effective way.
The next step is to become a discerning consumer. Research strains, question product claims, and consider more potent approaches like home fermentation. Your microbiome is a complex and unique ecosystem; managing it knowledgeably is one of the most valuable investments you can make in your long-term well-being.
Why Don't We Offer Multi-Strain Probiotics?
Destructive Competition Between Strains
When multiple strains of probiotic bacteria are found in the same product, they can compete directly for the same resources and space in your gut. This microscopic battle can result in the more aggressive strains dominating the environment, eliminating or significantly inhibiting the more beneficial but less competitive strains. The result is a waste of your investment and unpredictable effectiveness.
Dilution of Potency and Effectiveness
Multi-strain products typically contain smaller amounts of each individual strain in order to include multiple varieties in a single capsule. This means you may not receive the necessary therapeutic dose of any specific strain. It's like taking multiple medications at insufficient doses: technically you're consuming "variety," but without reaching the levels needed for real benefits.
Impossibility of Therapeutic Personalization
Your microbiome is as unique as your fingerprint. While one person may need to strengthen their immune system with Lactobacillus rhamnosus, another may require improved digestion with Bifidobacterium longum. Multi-strain products force you into a "one-size-fits-all" approach that ignores your specific needs and may even introduce strains you don't need or that could be counterproductive for your particular situation.
Difficulty in Identifying Adverse Reactions
If you experience side effects or unwanted reactions with a multi-strain probiotic, it's virtually impossible to pinpoint which of the multiple strains is causing the problem. This turns the process of optimizing your gut health into a frustrating guessing game, where you can't eliminate the problematic strain without discarding the entire product.
Lack of Specific Scientific Evidence
Most clinical studies on probiotics are conducted with single strains or very specific, controlled combinations. Commercial multi-strain products have rarely undergone rigorous studies demonstrating that their particular combination of strains works better than the individual strains. You're essentially paying for an experiment without solid scientific backing.
Stability and Survival Problems
Different strains have different storage requirements, optimal pH levels, and survival conditions. When multiple strains are combined in a single product, it's impossible to optimize conditions for all of them. Some strains may deteriorate more quickly, completely disrupting the intended balance of the product even before it reaches your gut.
Precise Focus vs. Dispersed Effort
We prefer a sniper-like approach to a shotgun-like one. Each of our individual strains has been selected for its specific ability to address particular issues, backed by solid research and dosed appropriately. This allows you to build your probiotic protocol strategically, adding one strain at a time and evaluating its effects before introducing the next.
Greater Control and Flexibility in Treatment
With single-strain probiotics, you have complete control over your gut health protocol. You can adjust dosages individually, introduce strains gradually, make strategic rotations, and create custom combinations based on your unique response. This flexibility is impossible with pre-made, multi-strain products that limit you to the manufacturer's formulation decisions.
Why do we add FOS (Fructooligosaccharides)?
FOS are specific prebiotics that act as selective fuel exclusively for beneficial bacteria such as Lacticaseibacillus rhamnosus GG, creating a powerful synergy that exponentially multiplies the probiotic's effectiveness. Unlike other carbohydrates that can feed both beneficial and pathogenic bacteria, FOS have a unique molecular structure that can only be fermented by specific probiotic species, ensuring that all nutritional energy is directed toward strengthening LGG and other beneficial bacteria.
When LGG ferments FOS in the colon, it produces short-chain fatty acids such as butyrate, propionate, and acetate, which acidify the intestinal environment, creating inhospitable conditions for pathogenic bacteria while providing direct energy to colon cells. This selective fermentation can increase the viable LGG population up to 100 times compared to its use without prebiotics, establishing a more robust and longer-lasting colonization.
FOS also stimulate the expression of adhesion proteins in LGG, improving its ability to adhere firmly to the intestinal epithelium and resist the natural washout during intestinal transit. This enhanced adhesion is essential for LGG to exert its sustained immune-modulating and intestinal barrier-strengthening effects.
Furthermore, the fermentation of FOS by the LGG produces specific metabolites that stimulate mucin production by goblet cells, strengthening the intestinal lining. FOS also act as molecular signals that activate genes in the LGG related to the production of bacteriocins and other antimicrobial compounds, enhancing its natural defense capabilities.
The inclusion of FOS ensures that the LGG has immediate access to its preferred energy source from the moment of administration, eliminating dependence on the user's diet to provide the substrates necessary for optimal colonization. This synergistic combination guarantees faster, more consistent, and longer-lasting results compared to probiotics without prebiotic support.

Luego se 21 días sin ver a mi esposo por temas de viaje lo encontré más recuperado y con un peso saludable y lleno de vida pese a su condición de Parkinson!
Empezó a tomar el azul de metileno y
ha mejorado SIGNIFICATIVAMENTE
Ya no hay tantos temblores tiene más equilibrio, buen tono de piel y su energía y estado de ánimo son los óptimos.
Gracias por tan buen producto!
Empezé con la dosis muy baja de 0.5mg por semana y tuve un poco de nauseas por un par de días. A pesar de la dosis tan baja, ya percibo algun efecto. Me ha bajado el hambre particularmente los antojos por chatarra. Pienso seguir con el protocolo incrementando la dosis cada 4 semanas.
Debido a que tengo algunos traumas con el sexo, me cohibia con mi pareja y no lograba disfrutar plenamente, me frustraba mucho...Probé con este producto por curiosidad, pero es increíble!! Realmente me libero mucho y fue la primera toma, me encantó, cumplió con la descripción 🌟🌟🌟
Super efectivo el producto, se nota la buena calidad. Lo use para tratar virus y el efecto fue casi inmediato. 100%Recomendable.
Desde hace algunos años atrás empecé a perder cabello, inicié una serie de tratamientos tanto tópicos como sistémicos, pero no me hicieron efecto, pero, desde que tomé el tripéptido de cobre noté una diferencia, llamémosla, milagrosa, ya no pierdo cabello y siento que las raíces están fuertes. Definitivamente recomiendo este producto.
Muy buena calidad y no da dolor de cabeza si tomas dosis altas (2.4g) como los de la farmacia, muy bueno! recomendado
Un producto maravilloso, mis padres y yo lo tomamos. Super recomendado!
Muy buen producto, efectivo. Los productos tienen muy buenas sinergias. Recomendable. Buena atención.
Este producto me ha sorprendido, yo tengo problemas para conciliar el sueño, debido a malos hábitos, al consumir 1 capsula note los efectos en menos de 1hora, claro eso depende mucho de cada organismo, no es necesario consumirlo todos los días en mi caso porque basta una capsula para regular el sueño, dije que tengo problemas para conciliar porque me falta eliminar esos habitos como utilizar el celular antes de dormir, pero el producto ayuda bastante para conciliar el sueño 5/5, lo recomiendo.
Con respecto a la atención que brinda la página es 5 de 5, estoy satisfecho porque vino en buenas condiciones y añadió un regalo, sobre la eficacia del producto aún no puedo decir algo en específico porque todavía no lo consumo.
Compre el Retrauide para reducir mi grasa corporal para rendimiento deportivo, realmente funciona, y mas que ayudarme a bajar de peso, me gusto que mejoro mi relacion con la comida, no solo fue una reduccion en el apetito, sino que directamente la comida "chatarra" no me llama la atencion como la hacia antes. Feliz con la compra.
Pedí enzimas digestivas y melón amargo, el proceso de envío fué seguro y profesional. El producto estaba muy bien protegido y lo recogí sin inconvenientes.
