# Type I Marine Collagen (Pisces) **Canonical URL:** https://ingredients.hermeticasuperfoods.com/ingredients/type-i-marine-collagen **Data Source:** Hermetica Superfoods Ingredient Encyclopedia **Updated:** 2026-03-31 **Evidence Score:** 2 / 10 **Category:** Protein **Also Known As:** Fish collagen type I, Marine fish collagen, Piscine collagen type I, Fish-derived collagen, Ichthyocol, Marine-sourced collagen type I, Fish skin collagen, Teleost collagen ## Overview Type I marine collagen from fish contains hydroxyproline and glycine amino acids that theoretically support [collagen synthesis](/ingredients/condition/skin-health) pathways. Current research focuses only on extraction methods with no documented clinical health benefits. ## Health Benefits • No clinical health benefits documented - available research focuses only on extraction methods and structural characterization • Potential biomedical applications suggested but not clinically tested • Native triple-helical structure preserved during extraction may support theoretical tissue engineering uses (no clinical evidence) • High purity confirmed by spectroscopic analyses but therapeutic effects unverified • Industrial potential noted for pharmaceutical applications without human trial data ## Mechanism of Action Type I marine collagen provides hydroxyproline, glycine, and proline amino acids that serve as building blocks for endogenous [collagen synthesis](/ingredients/condition/skin-health). The preserved triple-helical structure may theoretically interact with collagen receptors and support tissue matrix formation. However, specific molecular pathways and receptor interactions remain unstudied in clinical settings. ## Clinical Summary No clinical trials have evaluated the health benefits of Type I marine collagen supplements. Available research consists entirely of extraction methodology studies and structural characterization analyses. While some papers suggest potential biomedical applications, these remain theoretical without human testing. The evidence base is limited to laboratory extraction techniques and molecular structure documentation. ## Nutritional Profile Type I Marine Collagen (Pisces) is composed predominantly of protein, typically 85–95% by dry weight, with the characteristic amino acid composition of fibrillar collagen: glycine (~33% of total amino acids), proline (~13%), hydroxyproline (~9–12%), alanine (~11%), and glutamic acid (~~7%). Hydroxyproline content is notably lower than bovine Type I collagen, reflecting the cold-water adaptation of fish species. Total nitrogen content approximates 16–18% by dry weight. Carbohydrate content is negligible (<1%). Lipid content is very low (<2%), though trace omega-3 fatty acid residues may persist depending on extraction purity. Ash/mineral content typically ranges 0.3–1.5% and may include trace calcium, phosphorus, sodium, and magnesium retained from fish bone or skin matrices. No significant vitamins are present. The protein is devoid of tryptophan (making it an incomplete protein by essential amino acid standards) and low in methionine and histidine. Molecular weight of extracted triple-helical chains: α1 and α2 chains at approximately 100–140 kDa each, confirmed by SDS-PAGE. Bioavailability: intact high-molecular-weight collagen has low direct bioavailability; hydrolyzed forms (collagen peptides, MW 0.3–8 kDa) demonstrate significantly improved gastrointestinal absorption. Native triple-helical structure is preserved at low processing temperatures, confirmed by FTIR and circular dichroism spectroscopy, with denaturation temperature (Td) typically 25–30°C — lower than mammalian collagen due to lower hydroxyproline density. ## Dosage & Preparation No clinically studied dosage ranges available as human trials are absent from the research. Extraction yields of 50-63% dry weight are reported for production purposes only, with no data on supplementation dosing. Consult a healthcare provider before starting any new supplement. ## Safety & Drug Interactions Safety data for Type I marine collagen supplements is unavailable due to lack of clinical studies. Potential allergic reactions may occur in individuals with fish allergies. Drug interactions and contraindications have not been studied or documented. Pregnancy and breastfeeding safety cannot be determined without clinical research data. ## Scientific Research No human clinical trials, randomized controlled trials, or meta-analyses were found in the research dossier for Type I Marine Collagen. Available studies focus exclusively on extraction methodologies, structural characterization via FTIR and X-ray diffraction, and yield optimization without any clinical outcome data. ## Historical & Cultural Context No traditional or historical medicinal use documented in the research. Current applications emphasize modern industrial extraction from fish processing by-products rather than any ethnomedical heritage. ## Synergistic Combinations Insufficient evidence to recommend synergistic compounds ## Frequently Asked Questions ### What is Type I marine collagen made from? Type I marine collagen is extracted from fish (Pisces) tissues, particularly skin and scales. The extraction process preserves the native triple-helical protein structure containing hydroxyproline and glycine amino acids. ### Are there proven benefits of marine collagen supplements? No clinical health benefits have been documented for Type I marine collagen supplements. Current research focuses only on extraction methods and structural analysis, not human health outcomes. ### How much marine collagen should I take daily? No established dosage recommendations exist for Type I marine collagen since clinical efficacy studies have not been conducted. Supplement labels vary widely without scientific basis for optimal amounts. ### Is marine collagen better than bovine collagen? Comparative effectiveness studies between marine and bovine collagen have not been performed. Both lack clinical evidence for health benefits, making superiority claims unsupported by research. ### Can marine collagen cause side effects? Side effects of Type I marine collagen supplements are unknown due to absence of clinical studies. Individuals with fish allergies should avoid marine collagen products as allergic reactions are theoretically possible. ### What does research say about marine collagen's effectiveness compared to other collagen sources? Current clinical evidence for marine collagen is limited, with most research focusing on extraction methods and molecular structure rather than therapeutic outcomes in humans. While marine collagen's preserved triple-helical structure shows theoretical promise for tissue engineering applications, these benefits have not been clinically validated in supplement form. Comparative efficacy studies between marine and other collagen types in humans remain sparse, making evidence-based conclusions difficult. ### Is Type I marine collagen safe for people with fish allergies? Type I marine collagen derived from fish sources may pose a risk for individuals with fish allergies, as processing cannot completely eliminate allergenic proteins. People with shellfish or fish sensitivities should consult a healthcare provider before use, as cross-reactivity is possible depending on the extraction source and purity methods. Always verify the specific fish source and manufacturing transparency with the supplement provider. ### How is the purity of marine collagen supplements verified? Marine collagen purity is typically confirmed through spectroscopic analyses and structural characterization techniques that assess collagen concentration and amino acid profiles. However, purity verification does not guarantee bioavailability or clinical efficacy in the human body. Third-party testing certifications and transparent manufacturing disclosures are important indicators of quality, though they should be independently verified. --- *Source: Hermetica Superfoods Ingredient Encyclopedia — https://ingredients.hermeticasuperfoods.com* *License: CC BY-NC-SA 4.0 — Attribution required.
