'Certified Bio-Assay' Deglycyrrhizinated Licorice extract: What It Is, Benefits, Dosage, and Sources
"Certified Bio-Assay" Deglycyrrhizinated Licorice (DGL) extract refers to a specific type of licorice extract that has undergone a process to remove glycyrrhizin, the compound responsible for some of licorice's potential side effects, such as elevated blood pressure. The "certified bio-assay" aspect signifies that the extract's biological activity and purity have been verified through specific laboratory testing methods. This certification aims to assure consumers of the product's quality, consistency, and efficacy, particularly regarding its intended gastrointestinal benefits.
Understanding "Certified Bio-Assay" Deglycyrrhizinated Licorice (DGL) Extract
The term "certified bio-assay" indicates a level of quality control beyond standard ingredient testing. A bio-assay is a measurement of the concentration or potency of a substance by its effect on living cells or organisms. In the context of DGL, this means the extract has been tested to confirm its biological activity, often related to its ability to support mucosal integrity or exert anti-inflammatory effects, rather than just confirming the presence of certain chemical compounds. This distinction is important because the overall effect of a botanical extract can depend on a complex interplay of its constituents, not just a single isolated compound.
For DGL, the primary goal of deglycyrrhizination is to remove glycyrrhizin. Glycyrrhizin, while having some beneficial properties, can also inhibit an enzyme involved in cortisol metabolism, leading to increased cortisol levels and potential issues like hypertension and electrolyte imbalances, especially with prolonged, high-dose use of whole licorice. DGL aims to retain the beneficial compounds of licorice, such as flavonoids, which are thought to contribute to its soothing and protective effects on the digestive tract, without the associated risks of glycyrrhizin.
The "certified bio-assay" label suggests that the manufacturer has gone the extra step to ensure the deglycyrrhizination process was effective and that the remaining active compounds are present and biologically active at specified levels. This can be a practical consideration for consumers seeking a reliable and consistent product, as the quality of botanical extracts can vary widely depending on sourcing, processing, and manufacturing standards.
Deglycyrrhizinized Licorice (DGL) (Glycyrrhiza glabra) Root Extract
Glycyrrhiza glabra, commonly known as licorice, is a perennial herb native to southern Europe and Asia. Its root has been used for centuries in traditional medicine systems, including Traditional Chinese Medicine and Ayurveda, for a variety of ailments, particularly those affecting the digestive and respiratory systems. The plant's name, Glycyrrhiza, is derived from Greek words meaning "sweet root," a testament to its distinctive flavor.
The process of creating DGL involves extracting compounds from the licorice root and then specifically removing glycyrrhizin. This is typically done through a solvent extraction process followed by further purification steps. The resulting DGL extract should contain negligible amounts of glycyrrhizin, usually less than 1-2%, to be considered safe for long-term use without the glycyrrhizin-related side effects.
The remaining compounds in DGL, primarily flavonoids like liquiritigenin and isoliquiritigenin, are believed to be responsible for its therapeutic actions. These compounds are thought to stimulate the production of protective mucus in the digestive tract, enhance blood flow to the gastric lining, and possess antioxidant and anti-inflammatory properties. These mechanisms contribute to DGL's traditional and contemporary use in supporting gastrointestinal health.
For example, a person experiencing occasional heartburn or indigestion might consider DGL. Unlike antacids that primarily neutralize stomach acid, DGL is thought to work by strengthening the body's natural defense mechanisms in the stomach and esophagus. This approach focuses on enhancing the mucosal barrier, which acts as a protective shield against stomach acid and irritants.
Licorice - Supplement Ingredient Information
When examining licorice as a supplement ingredient, it's crucial to differentiate between whole licorice extract and DGL. Whole licorice extract contains glycyrrhizin and can be used for specific short-term purposes under professional guidance, but its long-term or high-dose use carries risks. DGL, on the other hand, is specifically formulated to mitigate these risks while retaining the beneficial compounds.
The "certified bio-assay" designation adds another layer of information for consumers. It implies that the manufacturer has invested in specific testing to validate the biological effect of their DGL extract. This is different from standard ingredient information, which might only list the botanical name, extraction ratio, or a general statement about active compounds. A bio-assay certificate would typically provide data on how the extract performs in a biological model relevant to its intended use, for instance, its ability to stimulate mucin production in a cell culture.
Consider the scenario of a supplement user researching ingredients for digestive support. They might encounter various forms of licorice. Without the "certified bio-assay" distinction, it can be challenging to assess the quality beyond basic DGL labeling. A product with this certification offers a potential advantage by providing a verifiable measure of its biological activity, suggesting a more rigorously tested ingredient. This can be particularly relevant in a market where the potency and purity of botanical extracts can vary significantly.
Gastric Support (G): Carnosoothe with PicroProtect
The mention of "Gastric Support (G): Carnosoothe with PicroProtect" in the context of DGL suggests a specific product formulation that includes DGL as a key ingredient, alongside others like PicroProtect (likely referring to Picrorhiza kurroa extract) and possibly L-Carnosine. This highlights a common practice in the supplement industry: combining complementary ingredients to achieve a broader or more targeted therapeutic effect.
In such a formulation, DGL's role would likely be to provide its established benefits for mucosal protection and soothing the digestive lining. PicroProtect, derived from Picrorhiza kurroa, is traditionally used in Ayurvedic medicine for liver support and its anti-inflammatory properties, which might extend to the gastrointestinal tract. L-Carnosine, particularly in its zinc-bound form (Zinc Carnosine), is also widely recognized for its ability to support gastric mucosal integrity and promote healing of the stomach lining.
The combination of these ingredients in a product like "Carnosoothe with PicroProtect" aims to offer comprehensive gastric support. DGL contributes to the protective barrier, PicroProtect might address inflammatory components, and Zinc Carnosine could aid in repair and healing. This synergistic approach is often utilized when addressing complex conditions like general gastric distress, occasional heartburn, or supporting the healing of gastric tissues.
For someone looking for a multi-faceted approach to gastric health, a product combining DGL with other supportive ingredients might be appealing. The "certified bio-assay" status of the DGL in such a blend would lend credibility to that specific component, assuring the user that the licorice extract itself meets certain standards of biological activity.
Carnosoothe with PicroProtect (60 vegetarian capsules)
This specific product listing provides more detail about the supplement format: "60 vegetarian capsules." This information is practical for consumers and indicates that the product is suitable for vegetarians and typically offers a month's supply if taken once or twice daily. The capsule form is a common delivery method for botanical extracts, providing convenience and often masking the taste of the ingredients.
When considering a product like "Carnosoothe with PicroProtect," the "certified bio-assay" DGL component is a notable feature. It suggests that the manufacturer has exercised due diligence in sourcing a high-quality licorice extract, ensuring its potency and safety profile. For example, if a person is sensitive to traditional licorice due to blood pressure concerns, the DGL form is crucial. The "certified bio-assay" label provides an additional layer of confidence that the deglycyrrhizination process has been effectively carried out and that the DGL is biologically active in the ways intended for gastric support.
The number of capsules and the vegetarian designation are important practical details for consumers. A person following a vegetarian diet would specifically look for this, and the capsule count helps in understanding the product's value and how long a single bottle will last based on the recommended dosage. This level of detail moves beyond just the ingredient discussion to the practical application of the supplement.
Life Extension CarnoSoothe with PicoProtect
"Life Extension" is a well-known brand in the supplement industry, often associated with science-backed formulations and quality control. Their inclusion of "Carnosoothe with PicoProtect" further reinforces the idea that DGL, especially "certified bio-assay" DGL, is a valued ingredient in advanced gastric support formulas.
When a reputable brand uses a "certified bio-assay" ingredient, it typically implies a level of commitment to efficacy and safety. Such brands often conduct their own third-party testing or work with ingredient suppliers who provide extensive documentation. For the consumer, this can translate into greater trust in the product's claims. For instance, if Life Extension states their DGL is "certified bio-assay," it suggests they have verified the bioactivity of the DGL extract they are using, aligning with their reputation for quality.
This product, like the others mentioned, would likely contain a blend of ingredients working synergistically. The DGL would contribute its mucosal protective properties, while PicroProtect and Zinc Carnosine would offer additional support for inflammation, healing, and overall gastric integrity. The "certified bio-assay" aspect of the DGL ingredient would be a key selling point, distinguishing it from generic DGL extracts that may not have undergone the same rigorous biological activity testing.
A consumer comparing different gastric support supplements might see various DGL products. The presence of "certified bio-assay" on a Life Extension product, for example, could be a deciding factor, suggesting a higher standard of ingredient quality and testing. This is particularly relevant given the variability in botanical supplement standardization.
Benefits of "Certified Bio-Assay" Deglycyrrhizinated Licorice Extract
The primary benefits of DGL revolve around its capacity to support the health and integrity of the gastrointestinal lining. The "certified bio-assay" aspect provides a layer of assurance regarding the potency and reliability of these benefits.
- Gastric Mucosal Protection: DGL is thought to stimulate the production and secretion of mucin, a key component of the protective mucus layer that lines the stomach and esophagus. This enhanced mucus barrier acts as a defense against stomach acid and digestive enzymes, which can otherwise irritate or damage the delicate tissues.
- Soothes Irritation: By strengthening the mucosal barrier, DGL can help soothe existing irritation and discomfort in the upper digestive tract, including the stomach and esophagus. This makes it a popular choice for individuals experiencing occasional indigestion or heartburn.
- Supports Digestive Healing: Some research suggests that DGL may promote the healing of the gastric lining by increasing blood supply to the area and stimulating the proliferation of protective cells. This can be beneficial for maintaining overall digestive health.
- Anti-inflammatory Properties (Localized): While glycyrrhizin is known for broader anti-inflammatory effects, the flavonoids in DGL also possess localized anti-inflammatory actions within the gut, further contributing to its soothing properties.
- Reduced Risk of Glycyrrhizin-Related Side Effects: The deglycyrrhizination process means that DGL offers these benefits without the concern of elevated blood pressure or electrolyte imbalances associated with the glycyrrhizin found in whole licorice. The "certified bio-assay" ensures that this removal has been effectively performed and verified.
For example, an individual who experiences occasional mild acid reflux after certain meals might find DGL helpful. Rather than simply suppressing acid, DGL aims to fortify the body's natural defenses, creating a more resilient digestive tract. The "certified bio-assay" ensures that the DGL they are taking is potent enough to deliver these protective effects.
Dosage of "Certified Bio-Assay" Deglycyrrhizinated Licorice Extract
Determining the appropriate dosage for DGL, especially "certified bio-assay" DGL, depends on the specific product, the concentration of the extract, and the individual's needs. However, general guidelines exist for DGL supplementation.
Common dosages for DGL extracts typically range from 300 mg to 400 mg per serving, taken two to three times daily, often before meals or at bedtime. For "certified bio-assay" products, the manufacturer's recommended dosage is particularly important, as the bio-assay certification might relate to a specific concentration or activity level that corresponds to their recommended intake.
It's common for DGL to be available in chewable tablet form, as the act of chewing is thought to activate certain compounds and mix them with saliva, which may enhance their local effect in the esophagus before they reach the stomach. Capsules are also widely available.
Important Considerations for Dosage:
- Follow Manufacturer's Instructions: Always adhere to the dosage instructions provided on the product label. "Certified bio-assay" products will have specific recommendations based on their verified potency.
- Consult a Healthcare Professional: Before starting any new supplement, especially for ongoing digestive issues, it's advisable to consult with a doctor or qualified healthcare practitioner. They can provide personalized advice, consider potential interactions with medications, and help rule out more serious underlying conditions.
- Start Low, Go Slow: If new to DGL, some individuals prefer to start with a lower dose and gradually increase it to the recommended amount to assess tolerance.
- Timing: Taking DGL 20-30 minutes before meals is a common recommendation, as it allows the protective compounds to coat the stomach and esophageal lining before food and acid are introduced.
For instance, a product might recommend 350 mg of "certified bio-assay" DGL chewable tablets, three times daily before meals. Following this specific guidance ensures the user is consuming the amount that has been validated for its biological activity.
Sources of "Certified Bio-Assay" Deglycyrrhizinated Licorice Extract
"Certified bio-assay" DGL extract is not found in natural food sources in its deglycyrrhizinized and bio-assayed form. It is a processed ingredient available primarily through dietary supplements. The "source" in this context refers to where you would find products containing this specific type of DGL.
- Dietary Supplements: The most common source is through various dietary supplement brands that offer DGL as a standalone product or as part of a blend for digestive support. Look for products explicitly stating "deglycyrrhizinized licorice extract" and, if possible, mentioning "certified bio-assay" or similar quality assurance indicators.
