Elastin Peptide Powder for Beauty & Nutraceutical Formulations
Bonito-derived elastin peptide powder for B2B ingredient sourcing, with ≥70% peptide content and controlled low-relative-molecular-weight peptide distribution. Review batch analytical data and technical qualification requirements below.

Peptide Content Is Not the Same as Elastin Purity
The certificate reports 91.4 g/100g as “Peptide Content.” It does not report 91.4% elastin purity. Likewise, the marker item is written as “Sum of chain elements and heterochain elements” with a 0.25% result; the certificate does not explicitly label this value as Desmosine or Isodesmosine.
Bonito-Derived Elastin Peptide Powder
The certificate identifies the product as Elastin Peptide Powder (Bonito). It controls peptide content, relative molecular-weight distribution, total nitrogen, a marker item, moisture, ash, heavy metals and microbiology.
For commercial qualification, use the current batch certificate together with fish-species, source-tissue, allergen, marker-definition and process documents required by your regulatory and formulation teams.

What Buyers Should Verify in a Bonito Elastin Peptide
Current commercial SERPs emphasize bonito source, low-molecular-weight peptides, marker amino acids, COA/TDS and sample access. This page keeps each claim tied to the documentation available.
Peptide Content
The certificate specifies ≥70.0 g/100g peptide content and reports 91.4 g/100g for this batch.
Low-MW Peptide Fraction
97.62% of the measured peptide fraction is below relative molecular weight 5,000; this is not an average molecular-weight value.
Marker Definition
Request the current TDS or analytical-method statement before naming the 0.25% Appendix A marker as desmosine or isodesmosine.
Elastin Peptide Powder for Product Development
These are formulation pathways, not clinical efficacy claims. Finished-product dose, solubility, stability and regulatory suitability require independent evaluation.
Beauty-From-Within
Evaluate bonito elastin peptide as a differentiated marine peptide ingredient in beauty nutrition concepts.
Drink Powders
Confirm solubility, flavor, odor and stability in the target beverage system before scale-up.
Capsules & Tablets
Review dose, excipient compatibility and powder handling in the intended solid dosage form.
Beauty Ingredient Blends
Evaluate compatibility with collagen peptides and other beauty-focused ingredients in the finished formula.
What to Request from an Elastin Peptide Supplier
For supplier qualification, current source, marker, allergen and processing documents are more useful than broad “anti-aging” claims.
Confirm peptide content, low-MW fraction, marker result, metals and microbiology.
The certificate states Bonito but does not print a Latin species or anatomical tissue.
Request documentation defining the Appendix A marker and whether it represents desmosine/isodesmosine.
The material is fish-derived; request the current target-market allergen declaration.
The certificate does not provide water-solubility, clinical dosage, MOQ, packaging or live inventory.

Elastin Peptide Powder Sourcing Questions
What is the source of this Elastin Peptide Powder?
The certificate identifies the product as Elastin Peptide Powder (Bonito). It does not state a Latin species or source tissue.
What is the peptide-content specification?
The specification is ≥70.0 g/100g peptide content. Batch 20260205 reports 91.4 g/100g.
Does 91.4% mean elastin purity?
No. The certificate calls this result Peptide Content, not elastin purity.
What does 97.62% below 5,000 mean?
It is the proportion of peptides with relative molecular weight below 5,000. It should not be presented as an average molecular weight of 5,000 Da.
Does the COA verify desmosine and isodesmosine?
The certificate contains a 0.25% Appendix A marker item but does not explicitly name it desmosine or isodesmosine. Request the current marker-definition document before using those terms.
Is this ingredient water soluble?
The certificate does not report a solubility result. Request a current TDS or solubility test if beverage performance is important.
Should I request fish allergen documentation?
Yes. The certificate identifies a bonito-derived ingredient, but it is not an allergen statement.
Can I request current technical documents and a sample?
Yes. Contact ATNUTRA with your target application, destination market and expected volume.
