Naticol Marine Collagen: Quality and Sustainability

Naticol® marine collagen: committed to quality and sustainability

Kollo uses Naticol® marine collagen to supply the collagen content of our supplement. It is 100% premium-grade fish collagen, derived from fish skin as a by-product of the fishing industry. We selected Naticol as our collagen source after a great deal of due diligence — searching for collagen peptides that combine high purity, integrity, ethical sourcing, and sustainability. This article shares some of what made us choose Naticol.

Naticol® marine collagen: traceability

The first element of Naticol that we love is Weishardt's commitment to traceability during production. The supply chain offers transparency so you can see what happens at every stage. The fish involved are from aquaculture (fish farming) rather than being wild-caught. Where wild fish are used, Naticol confirms these are from non-endangered species.

One advantage relates to sustainability. Farmed fish under controlled conditions can be produced more sustainably than some wild-catch practices that can put pressure on marine populations and habitats. Naticol carries the Friend of the Sea® sustainability certification for its marine origin, and Weishardt has published broader sustainability commitments around fish species diversification and environmental impact.

A commitment to quality

During the production of Naticol® marine collagen, every supplier is audited to check standards. All fish skin suppliers are EU-approved and subject to Weishardt's specifications, with regular audits. Weishardt manually checks that its processes meet standards for both preserving the quality and integrity of the collagen.

Environmental considerations sit alongside quality. Naticol's marine sourcing produces meaningfully lower greenhouse gas emissions than bovine or porcine collagen production — a point Weishardt has publicly committed to as part of its sustainability position. Use of antibiotics is low, and chemicals that could contaminate the collagen are not used in processing.

Naticol® marine collagen: durability

Purity and integrity are the priority when producing the collagen peptides in Naticol®. Weishardt uses a proprietary two-step process: first, extraction of the collagen from the fish skin and purification of the extracted collagen; second, enzymatic hydrolysis of the extracted collagen and purification of the collagen peptides. Enzymatic (rather than acid) processing protects the end product against damage and contamination.

Other noteworthy features of Naticol's production include:

• A commitment to zero waste, with by-products of the fishing industry upcycled into a valuable product
• Ongoing social and economic commitments through Weishardt's operations
• An active circular economy — the fish skins would otherwise be discarded
• An environmentally conscious approach throughout

Certifications

Naticol® holds a number of certifications that speak to its quality and inclusivity. Production happens in the EU, meaning strict food safety and regulatory standards apply.

• FSSC 22000 — food safety standard providing assurance that the collagen peptides are safe to consume and free from harmful contaminants. Involves rigorous assessment of processes and products
• ISO 9001 — international quality management standard
• EU approval — all fish skin suppliers are EU-approved
• Friend of the Sea® — sustainability certification for the marine origin
• Halal and Kosher certifications — supporting inclusivity and accessibility

Weishardt also holds broader social responsibility commitments through its published policies. Alongside these ingredient-level certifications, every batch of Kollo (the finished product) is also Informed Choice certified — independently tested for over 250 prohibited and potentially harmful substances.

Naticol® marine collagen: responsibility

Weishardt has a strong understanding of the responsibility to customers with Naticol® marine collagen — rigorous adherence to ethical values in sourcing and processing, resulting in a hydrolysed collagen product that is natural, well-characterised, and safe for consumers. The purity of the collagen content is over 99% (protein on dry basis).

Naticol® has been the subject of extensive scientific evaluation. Weishardt publishes research on the ingredient across the following application areas:

• Nutricosmetic — skin beauty and healthy ageing
• Joint comfort
• Healthy ageing
• Sports nutrition
• Intestinal comfort

These are the areas Naticol publicly documents as the focus of their scientific evidence base. Kollo selected Naticol because we wanted an ingredient with a genuine research base — not just marketing claims.

Bringing everything together

When you consume hydrolysed collagen, it's broken down in the gut into small peptides and free amino acids — particularly glycine and proline. These are absorbed into the bloodstream and provide the raw materials fibroblasts use to build new collagen. Dose matters: evidence supports 10g (10,000mg) per day for skin outcomes, with the joint research using a higher 5-15g range. Kollo delivers 10g of Naticol® per daily sachet, sitting at the round number for skin research and within the wider range for joint outcomes.

The traceability, quality, and responsibility Naticol brings are what made Weishardt's ingredient the right foundation for Kollo. We haven't looked back since going into production.

How Kollo builds on Naticol® marine collagen

Naticol® is the starting point for Kollo, and we've built on it to create a supplement that supports daily consistency and delivers a well-researched dose:

• Sustainability commitment extended — all our packaging is recyclable, including the sachets. You can recycle them through the TerraCycle scheme, so Kollo is as close to zero waste as we can practically design
• Efficacious dose — every Kollo sachet contains 10,000mg (10 grams) of Naticol® marine collagen peptides. This dose is based on the clinical research on skin outcomes, sitting at the round research number and within the wider 5-15g range used for joint studies
• Liquid format for daily consistency — a pre-measured tear-and-drink sachet is designed to support the daily habit that clinical research is based on. Consistency in daily use matters more than any format-related absorption differences (all hydrolysed collagen formats go through digestion; hydrolysis is what makes any format well-absorbed)
• Delicious taste from natural flavourings — making it a welcome addition to your daily routine

Complementary nutrients in the Kollo formula

In addition to collagen peptides, Kollo is formulated with complementary nutrients that support the body's natural collagen production. Vitamin C is a helpful cofactor for the enzymes involved in collagen synthesis, making it a key nutrient for the formation of healthy collagen — which is why each serving provides 100% of the recommended daily intake of vitamin C.

The formula also includes a B-vitamin complex (B1, B5, B6, B12) to support normal energy metabolism and other cellular processes that contribute to overall tissue health. While B vitamins are not direct building blocks of collagen, they help support the body's normal physiological functions involved in maintaining healthy skin and connective tissues.

We also include L-lysine, an essential amino acid that is incorporated into collagen proteins and is required for normal collagen formation. Beyond its role in protein synthesis, L-lysine supports normal growth and tissue repair and contributes to overall health.

Together, these carefully selected nutrients complement the collagen peptides — providing nutritional support for collagen formation while delivering broader benefits.

Kollo is not suitable for anyone with a fish allergy.
