# BioClosed (Colostrum) **Canonical URL:** https://ingredients.hermeticasuperfoods.com/ingredients/bioclosed **Data Source:** Hermetica Superfoods Ingredient Encyclopedia **Updated:** 2026-03-20 **Evidence Score:** 2 / 10 **Category:** Other **Also Known As:** Bos taurus colostrum, Bovine colostrum, First milk, Beestings, Bisnings, Foremilk, Cow colostrum ## Overview BioClosed is a proprietary colostrum ingredient processed to preserve immunoglobulins—particularly secretory IgA and IgG—which bind pathogens and modulate mucosal immune responses. It also delivers bioactive amino acids, with glutamic acid comprising approximately 13.8% of its amino acid profile, supporting gut epithelial integrity. ## Health Benefits • No clinical evidence available - research dossier contains no human trials or studies demonstrating specific health benefits • Processing preserves immunoglobulins (IgA, IgG) though concentrations not quantified - no efficacy data provided • Contains amino acids including glutamic acid (13.8%) and proline (12.3%) - nutritional content only, no health outcomes studied • Low fat content (0.31%) in processed powder - compositional data only, no clinical significance established • Contains vitamin E (2.33 mg/100g) - nutrient presence noted but no therapeutic effects documented ## Mechanism of Action BioClosed colostrum supplies secretory IgA and IgG immunoglobulins that bind microbial antigens in the gut lumen, preventing epithelial adhesion and systemic translocation. Proline-rich polypeptides (PRPs) present in colostrum modulate [cytokine](/ingredients/condition/inflammation) signaling by interacting with lymphocyte receptors, potentially shifting Th1/Th2 balance. Glutamic acid and other amino acids serve as preferential fuel for enterocytes, supporting tight junction protein expression and intestinal barrier function. ## Clinical Summary BioClosed as a specific branded ingredient currently lacks published human clinical trials demonstrating quantified efficacy outcomes, making evidence-based claims premature. Broader bovine colostrum research includes randomized controlled trials in athletes and immunocompromised populations, with some studies (n=20–140) showing reduced upper respiratory tract infection incidence and modest IgA secretion increases. However, immunoglobulin concentrations in BioClosed are not publicly quantified, limiting direct extrapolation from general colostrum literature. The overall evidence base for colostrum supplements is considered preliminary, with heterogeneous study designs and small sample sizes. ## Nutritional Profile BioClosed (Colostrum) is a processed bovine colostrum ingredient with a low fat content of 0.31%. Protein-rich composition with amino acid profile including glutamic acid (13.8%) and proline (12.3%) as dominant amino acids. Contains immunoglobulins IgA and IgG preserved through proprietary processing — exact concentrations not quantified in available data. As a colostrum-derived ingredient, it likely retains growth factors (IGF-1, TGF-beta), lactoferrin, and lactoperoxidase typical of bovine colostrum, though specific concentrations for this formulation are not confirmed. Carbohydrate content includes lactose typical of dairy-derived ingredients. Micronutrient content expected to include calcium, phosphorus, magnesium, and fat-soluble vitamins (A, D, E, K) inherent to colostrum, but concentrations are not quantified in the available dossier. Bioavailability of immunoglobulins is processing-dependent; the 'BioClosed' designation suggests a method intended to preserve native protein structures, though bioavailability data in humans is not established in the available research dossier. ## Dosage & Preparation No clinically studied dosage ranges are available in the research. Processing yields indicate 10 kg raw colostrum refines to 1.3 kg powder, but no human dosing data or standardization levels are provided. Consult a healthcare provider before starting any new supplement. ## Safety & Drug Interactions Bovine colostrum is generally well-tolerated in healthy adults, with mild gastrointestinal symptoms such as bloating and nausea reported at higher doses. Individuals with cow's milk allergy or lactose intolerance should avoid colostrum-based products, including BioClosed, due to shared dairy proteins. No clinically established drug interactions are documented, though theoretical concerns exist around colostrum's [immunomodulatory](/ingredients/condition/immune-support) effects potentially interfering with immunosuppressant medications such as cyclosporine or corticosteroids. Safety data in pregnant or breastfeeding women is insufficient, and use during these periods should be guided by a healthcare provider. ## Scientific Research No human clinical trials, RCTs, or meta-analyses were found in the research dossier for BioClosed (Colostrum) or general bovine colostrum. No PubMed PMIDs are available for clinical studies on efficacy or health outcomes. ## Historical & Cultural Context The research dossier contains no information on historical or traditional medicinal uses of BioClosed (Colostrum) in any systems. No traditional use data is available. ## Synergistic Combinations No synergistic ingredients identified in research ## Frequently Asked Questions ### What makes BioClosed colostrum different from regular bovine colostrum? BioClosed is a proprietary processing technology designed to preserve heat-sensitive immunoglobulins—specifically IgA and IgG—that are often degraded during standard colostrum manufacturing. The processing aims to maintain the structural integrity of these proteins so they remain bioactive upon ingestion. However, the exact immunoglobulin concentrations achieved by the BioClosed process have not been publicly disclosed or independently verified in published research. ### Does BioClosed colostrum actually boost the immune system? No human clinical trials specific to BioClosed have been published demonstrating immune-boosting efficacy. General bovine colostrum research suggests IgA and IgG may support mucosal immunity by neutralizing pathogens in the gut, and proline-rich polypeptides may modulate cytokine activity. Until BioClosed-specific trials with quantified immunological endpoints are available, immune benefit claims remain extrapolated from broader colostrum literature. ### What amino acids are in BioClosed colostrum and what do they do? BioClosed colostrum contains glutamic acid as its most abundant amino acid at approximately 13.8% of the total amino acid profile. Glutamic acid serves as a primary energy substrate for intestinal epithelial cells and is a precursor to glutamine, which supports tight junction integrity and mucosal barrier defense. The full amino acid breakdown beyond glutamic acid has not been comprehensively published for this specific branded ingredient. ### Is BioClosed colostrum safe for people with dairy allergies? No—BioClosed is derived from bovine colostrum, which contains casein, whey proteins, and lactose similar to cow's milk, making it contraindicated for individuals with cow's milk protein allergy or significant lactose intolerance. Allergic reactions could range from gastrointestinal distress to more serious immune-mediated responses. Anyone with a diagnosed dairy allergy should avoid this ingredient and consult an allergist before considering colostrum-based supplements. ### What is the recommended dosage for BioClosed colostrum? No clinically established dosage has been published specifically for BioClosed colostrum, as no human dose-finding trials exist for this proprietary ingredient. General bovine colostrum research has used doses ranging from 400 mg to 3,000 mg per day in various study populations, with athletic performance studies often using 20–60 g daily of whole colostrum powder. Consumers should follow the manufacturer's label guidance and consult a healthcare provider for personalized dosing. ### Is BioClosed colostrum safe during pregnancy and breastfeeding? BioClosed colostrum is derived from bovine sources and is generally recognized as safe for most populations; however, pregnant and breastfeeding individuals should consult their healthcare provider before use, as specific safety data in these populations has not been formally studied. While colostrum is a natural food product, no clinical trials have specifically evaluated its safety profile during pregnancy or lactation. ### Does BioClosed colostrum interact with medications or antibiotics? No documented drug interactions have been reported with BioClosed colostrum, though formal interaction studies have not been conducted. If you are taking medications, particularly immunosuppressants or antibiotics, consult your healthcare provider before adding colostrum supplementation, as immunoglobulin-rich products may theoretically affect medication efficacy in certain contexts. ### Who should avoid BioClosed colostrum and why? Individuals with dairy allergies or lactose intolerance should avoid BioClosed colostrum, as it is a bovine-derived dairy product despite processing. Those with autoimmune conditions or immunocompromised states should consult a healthcare provider before use, since colostrum's immunoglobulin content may affect immune function, though no adverse events have been formally documented. --- *Source: Hermetica Superfoods Ingredient Encyclopedia — https://ingredients.hermeticasuperfoods.com* *License: CC BY-NC-SA 4.0 — Attribution required.
