Eggshell Membrane Collagen Powder for Nutraceutical Formulations
Chicken membrane-derived eggshell membrane powder for B2B ingredient sourcing, standardized by protein, glycosaminoglycan and hyaluronic acid specifications. Review batch analytical data, technical qualification points and formulation pathways below.
Protein Assay Is Not the Same as Collagen Percentage
The certificate identifies the product as Eggshell Membrane Collagen, but its ≥80% assay is labeled “Protein,” not “Collagen.” The tested 82.3% result should therefore be presented as total protein. The certificate also does not quantify collagen Types I, V or X, so this page does not publish type-specific percentages.
Eggshell Membrane as a Multi-Component Protein Matrix
The analytical certificate identifies Chicken Membrane as the origin and controls total protein, glycosaminoglycan, hyaluronic acid, ash, loss on drying, pH, fat, bulk density, heavy metals, particle size and microbiology.
This makes the ingredient suitable for technical comparison as a natural membrane matrix rather than an isolated collagen peptide. Claims about clinical efficacy, exact collagen types, low-dose performance or hydrolysis status require separate product-specific documentation.

Three Measurable Eggshell Membrane Components
Current SERP pages often describe eggshell membrane as a multi-component ingredient. This page limits that positioning to the three quantitative assays actually present in the certificate.
Protein ≥80%
The batch reports 82.3% total protein. This is not presented as a measured collagen percentage.
GAG ≥2%
The glycosaminoglycan specification is ≥2.0%, with a tested batch result of 15.2%.
Hyaluronic Acid ≥2%
The hyaluronic-acid specification is ≥2.0%, with a tested batch result of 4.3%.
Eggshell Membrane Powder for Product Development
These are formulation pathways rather than efficacy claims. Confirm serving size, sensory properties, dosage-form compatibility and regulatory positioning in the finished product.
Joint & Mobility Supplements
Use the standardized protein, GAG and HA data when evaluating joint-focused ingredient systems.
Beauty-From-Within
Evaluate the natural membrane matrix in beauty supplement concepts without transferring unsupported clinical claims.
Capsules & Tablets
Review bulk density, particle size, excipient compatibility and serving size for solid-dose development.
Powder Blends
Assess flow, dispersibility, flavor compatibility and stability in sachets or blended nutrition powders.
What to Request from an Eggshell Membrane Supplier
Current B2B SERP pages prominently surface assay, bulk quote, packaging, COA and application information. For an egg-derived ingredient, allergen and process documentation should also be part of qualification.
Confirm protein, GAG, hyaluronic acid, density, particle size and microbiology on the lot being purchased.
The certificate identifies Chicken Membrane as the origin, but it is not itself an allergen declaration. Request the current market-specific statement.
Request cleaning, separation, drying or hydrolysis information if process details matter to labeling or formulation.
Do not transfer branded eggshell-membrane clinical evidence or low-dose claims unless it applies to this exact ingredient and specification.
The certificate records a 2,000 kg batch quantity, but does not specify commercial pack size, MOQ or current stock.
Eggshell Membrane Powder Sourcing Questions
What is the source of this Eggshell Membrane Collagen?
The analytical certificate identifies the origin as Chicken Membrane.
What is the protein specification?
The specification is ≥80.0% total protein. Batch 20261028 reports 82.3%.
Is 82.3% the collagen content?
No. The certificate labels this assay as Protein. It does not provide a separate quantitative collagen assay.
How much glycosaminoglycan and hyaluronic acid are specified?
The specification requires ≥2.0% glycosaminoglycan and ≥2.0% hyaluronic acid. The batch reports 15.2% GAG and 4.3% hyaluronic acid.
Does the COA verify collagen Types I, V and X?
No. The certificate does not quantify or separately identify collagen Types I, V or X, so this page does not present them as measured batch composition.
Is this hydrolyzed eggshell membrane?
The certificate does not state hydrolysis status. Request the current TDS or process declaration if native versus hydrolyzed form matters to your formulation.
Is there a clinically proven low dosage?
The analytical certificate does not provide clinical data or a recommended dose. Any clinical-dose claim requires evidence specific to the commercial ingredient being sold.
Should I request an egg allergen statement?
Yes. The raw-material origin is Chicken Membrane, but the analytical certificate is not an allergen statement. Request current target-market allergen documentation.
Can I request current technical documents and a sample?
Yes. Contact ATNUTRA with your target application, destination market and expected volume to request documentation, material availability and pricing.
