Grass-fed cattle produce collagen with a different biochemical profile to grain-fed alternatives. A natural pasture diet supports a cleaner amino acid profile and eliminates the exposure to synthetic hormones and intensive feedlot inputs that can affect the integrity of the raw material.

For premium collagen ingredient applications, grass-fed sourcing is not a marketing distinction — it is a measurable quality variable that begins at the animal and carries through to the finished ingredient.

All Cellgen™ is produced from 100% Australian grass-fed bovine, raised without growth hormones or artificial inputs.

Collagen degradation begins at the molecular level from the moment the hide is separated from the animal. Extended storage, drying or international transport before processing introduces lag that affects the bioactive integrity of the raw material — and therefore the functional performance of the finished ingredient.

This is one of the most significant and least discussed quality variables in the collagen ingredient market. A premium Australian bovine hide, processed immediately at the point of origin, delivers a fundamentally different starting material — and finished ingredient — than the same hide dried, exported, transported and processed weeks or months later.

Cellgen™ is processed in real-time at the point of origin, eliminating every lag point in the conventional supply chain.

Fresh hides enter processing immediately after harvest — preserving maximum bioactive integrity at the molecular level. Dried or frozen hides have undergone a stabilisation process that slows — but does not stop — molecular degradation. By the time dried hides reach a processing facility after export and transport, the bioactive potential of the raw material has already diminished.

The difference is visible in the finished product. Fresh-processed collagen retains a naturally creamy character — a marker of minimal chemical intervention. Commodity collagen processed from dried or frozen hides typically requires bleaching to achieve the bright white powder appearance that has become standard in the market. That white colour is not a marker of purity — it is a marker of processing.

A number of brands in the Australian market source their raw material from Australian cattle but export dried hides offshore — typically to the United States or Europe — for processing into collagen powder. The finished product is then reimported and sold in Australia, often marketed as “Australian collagen” or “Australian sourced.”

Under Australian consumer law, this product cannot carry the Australian Made label — because the substantial transformation, which is the processing, did not occur in Australia. It may be accurately described as “Australian sourced” in terms of raw material origin — but the supply chain includes a significant offshore processing gap that introduces lag, additional handling and reduced transparency.

Beyond labelling, the practice raises a more fundamental quality concern — drying hides for export and subjecting them to international transit before processing introduces the precise delays that most affect bioactive integrity.

Cellgen™ is sourced, processed and packaged on a single site in regional New South Wales. Every stage of the supply chain is documented and verifiable — from Australian pasture to finished ingredient.

Bovine Spongiform Encephalopathy — commonly known as mad cow disease — is a progressive neurological condition in cattle. Its detection in a country’s cattle population triggers significant regulatory restrictions on the export and use of bovine-derived ingredients in food, supplement and pharmaceutical applications globally.

Australia has never had a detected case of BSE and maintains one of the world’s strongest BSE-free statuses — a critical compliance credential for bovine collagen ingredients destined for nutraceutical, supplement and functional food applications in international markets.

All Cellgen™ is produced from BSE-free Australian bovine and carries full documentation to support regulatory compliance in export markets.

Hormone Growth Promotants are synthetic or natural hormones used in some cattle farming systems to accelerate animal growth. Their use is tightly regulated in Australia, and cattle raised for premium ingredient supply are produced without HGPs.

HGP-free status is increasingly specified by premium supplement and nutraceutical brands as a sourcing requirement — both for clean label compliance and for consumer confidence in the integrity of animal-derived ingredients.

All Cellgen™ is produced from HGP-free Australian bovine, with full documentation available.

Independent Size Exclusion Chromatography testing by Macquarie University's Australian Proteome Analysis Facility — Lot 20250812 — shows the following distribution:

• 10–5 kDa: 48.4%
• 5–2.5 kDa: 34.7%
• 25–10 kDa: 10.2%
• 2.5–1 kDa: 5.8%
• Less than 1 kDa: 1.0%
• Greater than 25 kDa: 0.3%

83.1% of Cellgen™ peptides fall within the 2.5–10 kDa range identified as optimal for absorption and biological activity. Only 0.3% of peptides exceed 25 kDa. Independent testing conducted across the Australian collagen market has found that many brands fall significantly short of their stated molecular weight claims.

Size Exclusion Chromatography — also known as SEC or gel filtration chromatography — is an analytical technique used to separate and measure proteins and peptides by molecular size. In collagen testing, it provides a precise distribution of peptide molecular weights across the full range present in the sample — expressed as a percentage of total peptides at each size range.

This data is the most reliable measure of a collagen ingredient's functional quality because it directly reflects bioavailability potential. Peptides within the optimal absorption range — broadly 2.5 to 10 kDa — are most efficiently absorbed through the intestinal wall and most likely to deliver the bioactive effects attributed to collagen supplementation.

Cellgen™'s peptide profile has been validated via Size Exclusion Chromatography by Macquarie University's Australian Proteome Analysis Facility. Results show 83.1% of peptides within the 2.5–10 kDa range — significantly above independent market benchmarks.

In its natural state, collagen is a large, fibrous protein — too structurally complex to be absorbed efficiently by the body. Hydrolysis is the process that breaks collagen down into smaller peptide chains that can be absorbed through the intestinal wall and utilised systemically.

The quality of hydrolysis — the method used, the conditions applied, and the timing relative to raw material harvest — directly determines the bioavailability and functional performance of the finished collagen ingredient. Not all hydrolysis is equal, and the method used is one of the most important variables a formulation team should investigate when evaluating a collagen supplier.

Acid and alkaline hydrolysis are the most widely used industrial methods — fast, high-yield and cost-effective. Both involve harsh chemical conditions that can degrade sensitive amino acids, produce high salt concentrations in the finished product, generate chemical waste, and typically require bleaching to achieve the white powder appearance that has become standard in the commodity market.

Enzymatic hydrolysis uses specific enzymes under controlled temperature and pH conditions to cleave the peptide bonds within collagen. It is more selective, less damaging to the amino acid profile, and produces a cleaner finished ingredient without chemical intervention. Research consistently identifies enzymatic hydrolysis as the preferred method for premium collagen ingredient production.

Cellgen™ is produced using OTH's proprietary enzymatic extraction technology — a clean, controlled process that preserves bioactive integrity without acid treatment, alkaline treatment or bleaching.

Bleaching is used in commodity collagen processing to achieve the bright white powder appearance that has become the market standard. It is a chemical intervention — not a quality indicator.

The bleaching process can affect the amino acid profile of the finished ingredient, introduces additional chemical inputs that may compromise clean label status, and masks the natural characteristics of the raw material. A naturally creamy collagen powder — the result of fresh hide processing and minimal chemical intervention — is not a deficiency. It is what collagen actually looks like when it has not been chemically altered.

Cellgen™ contains no bleaching agents. Its naturally creamy finish reflects the integrity of the process, not a compromise in quality.

Most collagen brands in the Australian market do not conduct their own independent testing. Instead, they rely on data provided by their ingredient supplier — data which, where independently verified, has shown significant inaccuracies between claimed and actual peptide profiles across the market.

Batch testing matters because biological ingredients are variable. A supplier's certificate of analysis reflects one test at one point in time — not necessarily what is in the batch your formulation team receives. Independent batch testing by a third-party laboratory, conducted on the finished product before it leaves the facility, is the only way to verify what your formulation is actually receiving.

For brands making therapeutic health claims based on collagen's bioactive properties, the accuracy of peptide profile data is not a technical footnote — it is a foundational requirement.

Cellgen™ contains both Type I and Type III bovine collagen — the two collagen types most relevant across nutraceutical, supplement, functional food and beauty-from-within applications. Type I supports skin structure, tendons, bones and connective tissue. Type III works alongside Type I in skin architecture and is also found in gut lining, blood vessels, muscles and organs.

Cellgen™ contains greater than 90% protein by dry weight — consistent with a premium hydrolysed bovine collagen hydrolysate produced without fillers, binding agents or additives.

Cellgen™ contains 19 amino acids including 8 of the 9 essential amino acids — tryptophan is the only essential amino acid absent from collagen, which is standard across all collagen sources regardless of species or processing method.

The dominant amino acid is glycine at approximately 33.8 mole percent — significantly higher than in other protein sources. Other key amino acids include proline at 12.7%, alanine at 10.6% and hydroxyproline at 9.6%. Hydroxyproline is a signature amino acid found almost exclusively in collagen and serves as a measurable bioactive marker of collagen quality and authenticity.

The full amino acid profile is available in the Cellgen™ technical specification sheet, available to qualified partners upon request.

Yes. Cellgen™ is fully soluble in both hot and cold liquids without gelling or clumping, making it suitable for ready-to-drink beverage applications, powder sachets and hot beverage formats including coffee, tea and functional drink mixes.

Independent research published in 2025 found detectable levels of heavy metals including lead, cadmium, mercury and arsenic in some fish and jellyfish-derived collagen supplements. While levels were generally within tolerable daily limits when used as directed, the finding underscores the importance of rigorous independent testing regardless of collagen source.

For brands making premium health claims, the provenance, testing protocol and documentation of their collagen ingredient are non-negotiable — regardless of whether the source is marine or bovine.

Based on current peer-reviewed evidence, the answer is less clear than the marketing suggests. A growing body of research indicates that peptide size, processing method and dose are more significant determinants of clinical outcome than source species. The 2025 University Hospital of Schleswig-Holstein study concluded that clinical effectiveness does not primarily depend on the animal species from which the collagen peptides are derived.What matters most to your formulation team is whether the ingredient has been independently validated, properly hydrolysed to optimal molecular weight ranges, and produced from quality raw material without extended processing delays.

For skin, hair and nail formulations — Type I collagen is the primary target. Both marine and bovine deliver Type I, though bovine also provides Type III which supports skin architecture from a structural perspective.

For gut health formulations — Type III collagen, found in bovine but not marine, directly supports gut lining integrity and is the more relevant choice.

For joint health formulations — Type II collagen from chicken cartilage is the most studied. Bovine Type I and III also provide structural amino acid support for connective tissue.

For broad-spectrum wellness formulations — bovine collagen's Type I and III composition offers the most versatile single-ingredient solution across multiple health categories.

Yes — and the clinical evidence is stronger than the marine-dominated marketing landscape suggests. A 2025 double-blind, placebo-controlled trial of 66 women found statistically significant improvements in skin elasticity, hydration and wrinkle volume after eight weeks of daily bovine-derived bioactive collagen peptides. The researchers concluded that clinical effectiveness does not primarily depend on the animal species from which the peptides are derived.

Multiple systematic reviews confirm that collagen peptides from bovine, marine and porcine sources all demonstrate positive effects on skin health parameters — regardless of source, when the ingredient is properly hydrolysed and dosed appropriately.

Type I collagen is the most abundant protein in the human body — the primary structural component of skin, tendons, bones and connective tissue. It is the collagen type most associated with skin elasticity, hydration and structural integrity.

Type II collagen is found predominantly in cartilage and is most relevant for joint-specific formulations.

Type III collagen works alongside Type I and is found in skin, gut lining, blood vessels, muscles and organs. Its presence alongside Type I makes bovine collagen more versatile than marine collagen for formulations targeting multiple health outcomes simultaneously.

Marine collagen is predominantly Type I only. Bovine collagen contains both Type I and Type III — making it the stronger choice for formulations targeting skin, gut health, connective tissue and broader structural support in a single ingredient.
