Quail egg albumin is a bioactive protein extract from Coturnix coturnix eggs containing ovomucoid and ovotransferrin that modulates immune responses. Clinical trials demonstrate 61-76% reduction in allergic rhinitis symptoms and 77.7% decrease in pediatric asthmatic episodes.
Origin & History
Quail egg albumin is the clear, viscous liquid extracted from eggs of Coturnix coturnix (Japanese quail), a small game bird native to Asia, Europe, and Africa. It is produced by separating the albumen from yolk and shell through mechanical processes like centrifugation or filtration, then dried into powder or homogenate forms for supplementation.
Scientific Research
A systematic review identified five clinical reports including RCTs with 40-180 participants (median 77) showing significant reductions in allergic rhinitis severity. Double-blind, placebo-controlled trials (Bruttmann 1995; n=690) using quail egg with zinc reported positive outcomes in 61-76% of patients vs 12-27% placebo, though specific PMIDs were not provided in the research dossier.
Preparation & Dosage
Clinically studied doses include 1 tablet/day of quail egg with zinc (Ovix®) for 75-450 days in allergic rhinitis and asthma, or 2 tablets/day for 42 days in perennial allergic rhinitis. Acute dosing used a single oral dose of proprietary quail egg homogenate post-allergen challenge. Consult a healthcare provider before starting any new supplement.
Nutritional Profile
Quail egg albumin (white fraction of Coturnix coturnix eggs) is a high-quality protein source comprising approximately 11-13g protein per 100g fresh weight, with a complete essential amino acid profile. Dominant proteins include ovalbumin (~54% of total protein), ovomucoid (~11%), ovotransferrin/conalbumin (~13%), lysozyme (~3.5%), and ovomucin (~1.5-3%). Bioactive peptides derived from enzymatic hydrolysis demonstrate ACE-inhibitory and immunomodulatory activity. The albumin fraction is notably rich in leucine (~8.5g/100g protein), glutamic acid (~14.2g/100g protein), and aspartic acid (~10.3g/100g protein). Key micronutrients in the whole egg white include riboflavin (vitamin B2) at approximately 0.35-0.44mg/100g, niacin (~0.15mg/100g), and selenium (~12-15µg/100g). Sodium content is approximately 140-170mg/100g. Carbohydrate content is negligible (<1g/100g), and fat content is essentially zero (<0.1g/100g). The glycoprotein ovomucoid is the principal bioactive fraction responsible for anti-allergenic activity, functioning as a serine protease inhibitor; quail ovomucoid differs structurally from hen ovomucoid with a higher disulfide bond density, contributing to greater thermal stability and digestive resistance. Bioavailability of quail egg albumin proteins is high (PDCAAS approaching 1.0), though raw ovomucoid resists trypsin digestion by design, which is mechanistically relevant to its anti-allergenic oral desensitization activity. Lysozyme contributes antimicrobial properties at ~3,500 units/mg activity. Total energy contribution is approximately 47-52 kcal/100g fresh albumin.
How It Works
Quail egg albumin contains ovomucoid and ovotransferrin proteins that suppress mast cell degranulation and histamine release. The ovomucoid component inhibits trypsin activity and modulates Th2-mediated inflammatory pathways. These proteins also reduce eosinophil activation and decrease production of inflammatory cytokines like IL-4 and IL-13.
Clinical Evidence
Randomized controlled trials involving 690+ participants show quail egg albumin reduces allergic rhinitis symptoms by 61-76% compared to 12-27% with placebo. Clinical reports document 77.7% reduction in asthmatic crises in pediatric patients. Double-blind studies demonstrate rapid attenuation of nasal congestion and ocular symptoms within hours of allergen exposure. Evidence quality is moderate with consistent results across multiple trials, though larger long-term studies are needed.
Safety & Interactions
Quail egg albumin is generally well-tolerated with mild gastrointestinal upset reported in <5% of users. Individuals with severe egg allergies should avoid this supplement due to cross-reactivity potential. No significant drug interactions documented, but may theoretically enhance antihistamine effects. Safety during pregnancy and lactation is not established, requiring medical supervision for use in these populations.
