# Bovine Mammary Extract **Canonical URL:** https://ingredients.hermeticasuperfoods.com/ingredients/bovine-mammary-extract **Data Source:** Hermetica Superfoods Ingredient Encyclopedia **Updated:** 2026-03-31 **Evidence Score:** 2 / 10 **Category:** Protein **Also Known As:** BME, Cow mammary extract, Bovine mammary gland extract, Milk-fat-globule membrane extract, MFGM extract, Bovine udder extract, Mammary epithelial cell extract, Bos taurus mammary extract ## Overview Bovine mammary extract is a glandular supplement derived from cow mammary tissue, containing protein fractions such as CD36 from milk-fat-globule membranes and a defined amino acid profile including lysine (6.1%) and valine (7.0%). It is used in traditional glandular therapy under the premise that organ-specific proteins may support analogous human tissues, though no human clinical trials have validated this mechanism. ## Health Benefits • No clinically proven health benefits identified - no human clinical trials found in available research • Contains protein components including CD36 from milk-fat-globule membranes (evidence quality: none) • Contains amino acids including methionine 1.6%, lysine 6.1%, valine 7.0%, tryptophan 2.4% (evidence quality: none) • Total protein content of 61% in colostrum components (evidence quality: none) • No therapeutic applications documented in the research provided (evidence quality: none) ## Mechanism of Action Bovine mammary extract contains CD36, a scavenger receptor glycoprotein found on milk-fat-globule membranes that participates in lipid binding and fatty acid transport in mammalian tissue. The glandular therapy hypothesis proposes that organ-specific peptides and growth factors survive [digestion](/ingredients/condition/gut-health) and exert localized signaling effects on homologous human tissue, potentially modulating prolactin-sensitive pathways. However, no receptor-binding studies or enzyme-interaction data in humans have confirmed these proposed mechanisms for this specific extract. ## Clinical Summary No published human clinical trials have investigated bovine mammary extract as an isolated supplement, making evidence-based dosing or efficacy claims impossible at this time. The theoretical basis draws from broader glandular therapy literature, which itself consists largely of case reports and historical use rather than randomized controlled trials. The amino acid content — methionine 1.6%, tryptophan 2.4%, lysine 6.1%, valine 7.0% — is documented compositionally but has not been studied for pharmacological outcomes in this delivery format. Until peer-reviewed human trials are conducted, any claimed health benefit remains speculative and unsupported by current clinical evidence. ## Nutritional Profile Bovine Mammary Extract is a protein-rich ingredient derived from bovine mammary gland tissue, with protein content approximately 61% in colostrum-derived components. Amino acid profile includes lysine (6.1%), valine (7.0%), tryptophan (2.4%), and methionine (1.6%), indicating a moderate essential amino acid distribution. Contains bioactive proteins including CD36, a glycoprotein associated with milk-fat-globule membranes involved in fatty acid transport and lipid [metabolism](/ingredients/condition/weight-management). As a tissue-derived extract, it likely contains additional structural proteins such as caseins, whey fractions, and membrane-bound proteins native to mammary epithelial cells. Lipid-associated components from the milk-fat-globule membrane (MFGM) are probable, which typically include phospholipids (phosphatidylcholine, phosphatidylethanolamine, sphingomyelin) and cholesterol, though specific concentrations in this extract form are not quantified in available data. Micronutrient content is not well characterized for this specific extract, but bovine mammary tissue broadly contains trace minerals including zinc, calcium, and phosphorus inherent to protein structures. Bioavailability is presumed moderate-to-high given protein-based composition, though digestibility coefficients specific to this extract have not been established in published human studies. ## Dosage & Preparation No clinically studied dosage ranges are available for Bovine Mammary Extract in any form. The research describes only extraction processes without specifying therapeutic dosages or standardization. Consult a healthcare provider before starting any new supplement. ## Safety & Drug Interactions Because bovine mammary extract is derived from animal glandular tissue, individuals with beef or dairy protein allergies face a meaningful risk of allergic or hypersensitivity reactions, including urticaria or anaphylaxis in severe cases. Theoretical concerns exist around prion contamination in bovine glandular products, though commercial-grade extracts sourced from BSE-free herds are intended to minimize this risk. No formal drug interaction studies have been conducted; however, the presence of growth factors and bioactive peptides warrants caution when used alongside hormone-modulating medications or during pregnancy and lactation, where unstudied biological activity poses unknown fetal risk. Pregnant or breastfeeding individuals should avoid this supplement until safety data are available. ## Scientific Research No human clinical trials, RCTs, or meta-analyses on Bovine Mammary Extract were identified in the available sources. The research focuses solely on extraction protocols, microbiota analysis, and protein purification techniques, with no PubMed PMIDs for clinical studies in humans. ## Historical & Cultural Context No historical or traditional medicinal uses of Bovine Mammary Extract are documented in the available sources. The research emphasizes only modern extraction methods for colostrum powder or microbiota analysis. ## Synergistic Combinations No synergistic ingredients identified in research ## Frequently Asked Questions ### What is bovine mammary extract used for? Bovine mammary extract is used primarily in glandular therapy protocols, where practitioners hypothesize that proteins and peptides from cow mammary tissue may support human mammary or endocrine tissue function. Common anecdotal uses include breast health support and lactation-related concerns, but no human clinical trials confirm these applications. Its documented components include CD36 protein and amino acids such as lysine and valine, though therapeutic benefit from these specific fractions is unproven. ### Is there any scientific evidence that bovine mammary extract works? Currently, no human clinical trials have been published evaluating bovine mammary extract as a standalone supplement, meaning there is no direct scientific evidence supporting its efficacy for any health condition. Compositional data confirms the presence of CD36 protein from milk-fat-globule membranes and specific amino acids, but compositional characterization does not equal clinical proof of effect. Until randomized controlled trials are conducted, claims of benefit rely entirely on traditional glandular therapy theory. ### What compounds are in bovine mammary extract? Bovine mammary extract contains protein fractions including CD36, a glycoprotein scavenger receptor associated with lipid transport found on milk-fat-globule membranes. Its amino acid profile includes methionine at 1.6%, tryptophan at 2.4%, lysine at 6.1%, and valine at 7.0%, along with other naturally occurring peptides from mammary gland tissue. Growth factors and hormonal residues may also be present depending on the sourcing and processing method of the extract. ### Is bovine mammary extract safe to take? Bovine mammary extract carries safety concerns including allergic reactions for those sensitive to beef or dairy proteins, and a theoretical prion contamination risk inherent to all bovine glandular products. No formal toxicology or drug interaction studies have been published for this specific extract, leaving its safety profile formally uncharacterized. Individuals who are pregnant, breastfeeding, immunocompromised, or taking hormone-sensitive medications should avoid this supplement until adequate safety research is available. ### How does bovine mammary extract differ from whey protein or colostrum? Bovine mammary extract is derived from whole mammary gland tissue and contains organ-specific proteins like CD36 from fat-globule membranes, while whey protein is a filtered byproduct of cheese production consisting primarily of beta-lactoglobulin and alpha-lactalbumin. Colostrum, by contrast, is the first-milk secretion rich in immunoglobulins (IgG), lactoferrin, and insulin-like growth factor-1 (IGF-1), which have a substantially larger base of clinical research supporting immune and gut health applications. Bovine mammary extract represents a distinct glandular preparation with a far less studied evidence profile than either whey or colostrum. ### Can bovine mammary extract be used as a substitute for infant formula or colostrum supplementation? Bovine mammary extract should not be used as a substitute for infant formula, which is specifically formulated and regulated for infant nutrition and safety. While bovine mammary extract contains some protein and amino acids, it lacks the complete nutritional profile, proper mineral ratios, and quality controls required for infant feeding. Parents seeking colostrum or mammary-derived supplements for infants should consult healthcare providers for appropriate, clinically tested options. ### What is the difference between bovine mammary extract and bovine colostrum supplements? Bovine mammary extract is a broader category that can include various components from cow mammary tissue, while bovine colostrum specifically refers to the first milk secreted after calving, rich in immunoglobulins and growth factors. Colostrum is a more defined product with established composition, whereas bovine mammary extract may have variable composition depending on processing methods and tissue source. The two terms are sometimes used interchangeably in supplements, but colostrum is generally a more standardized and researched form. ### Are there quality or purity standards for bovine mammary extract products on the market? Bovine mammary extract products are not subject to strict FDA approval or standardized manufacturing requirements like pharmaceutical drugs, though some manufacturers may follow voluntary quality standards. Purity and potency can vary significantly between brands due to differences in sourcing, extraction methods, and processing techniques. Consumers should look for third-party testing certifications and verify the product's country of origin and manufacturing practices when selecting bovine mammary extract supplements. --- *Source: Hermetica Superfoods Ingredient Encyclopedia — https://ingredients.hermeticasuperfoods.com* *License: CC BY-NC-SA 4.0 — Attribution required.
