Naticol 1000 (Hydrolyzed fish collagen)

Naticol 1000 is a low-molecular-weight hydrolyzed fish collagen supplement containing type I collagen peptides that support skin health. It works by providing bioactive peptides that stimulate endogenous collagen synthesis and hyaluronic acid production in skin tissue.

Origin & History

Naticol 1000 is a branded hydrolyzed fish collagen peptide derived from fish skins, specifically from tilapia (Oreochromis genus) in some preparations, produced in Europe via enzymatic hydrolysis of fish gelatin. The manufacturing process involves filtration, pasteurization, and spray-drying, resulting in low molecular weight peptides (mean 2 kDa) with high purity (>93% collagen protein, >99.8% on dry matter).

Historical & Cultural Context

No historical or traditional medicine use is documented for Naticol 1000, as it is a modern branded ingredient produced via proprietary enzymatic hydrolysis. General fish collagen hydrolysates lack referenced traditional context in available sources.

Health Benefits

• Improved skin moisturization via upregulated hyaluronic acid synthesis (preclinical evidence only)
• Reduced wrinkle formation through enhanced collagen type I expression and TGF-β pathway activation (animal study evidence)
• Protection against UV-induced skin damage via antioxidant enzyme elevation (SOD, catalase, GPx) (mouse model evidence)
• Inhibited melanogenesis for potential skin brightening effects (in vitro evidence only)
• Enhanced ceramide synthesis for improved skin barrier function (preclinical evidence only)

How It Works

Naticol 1000 contains low-molecular-weight collagen peptides that activate the TGF-β signaling pathway, promoting collagen type I gene expression and synthesis. These peptides also upregulate hyaluronic acid synthase enzymes, increasing skin moisture retention. Additionally, the collagen fragments enhance antioxidant enzyme activity, protecting against UV-induced oxidative damage.

Scientific Research

No human clinical trials, RCTs, or meta-analyses specifically on Naticol 1000 were identified. Evidence is limited to one preclinical study using HaCaT keratinocytes, Hs27 fibroblasts, B16F10 melanocytes, and UVB-exposed SHK-I hairless mice, showing improvements in skin parameters (P<0.05 vs. UVB control).

Clinical Summary

Current evidence for Naticol 1000 is limited to preclinical and animal studies. In vitro studies demonstrate increased hyaluronic acid synthesis in cultured skin cells, while animal models show enhanced collagen type I expression and reduced wrinkle formation. UV protection effects have been observed through elevated antioxidant enzyme levels in laboratory settings. Human clinical trials are needed to confirm these preliminary findings and establish effective dosing protocols.

Nutritional Profile

Naticol 1000 is a low-molecular-weight hydrolyzed fish collagen (average molecular weight ~1000 Da) derived primarily from the skin and scales of wild-caught marine fish (typically cod, haddock, or similar species). **Protein content:** ~90–97% protein (on a dry weight basis), consisting almost entirely of collagen-derived peptides. **Amino acid profile (approximate per 100 g):** Glycine 20–25 g, Proline 10–13 g, Hydroxyproline 10–13 g (a hallmark amino acid of collagen, not found significantly in other dietary proteins), Alanine 8–10 g, Glutamic acid 9–11 g, Arginine 7–9 g, Aspartic acid 5–7 g, Lysine 3–4 g, Serine 3–4 g, Leucine 2–3 g, with lower amounts of other amino acids; notably low or absent in tryptophan and cysteine, making it an incomplete protein by essential amino acid standards. **Bioactive peptides:** Contains prolyl-hydroxyproline (Pro-Hyp) and hydroxyprolyl-glycine (Hyp-Gly) dipeptides and tripeptides (e.g., Gly-Pro-Hyp) that are the primary bioactive fractions responsible for stimulating fibroblast activity and collagen synthesis; these di/tripeptides can reach ~20–30% of total peptide content depending on hydrolysis conditions. **Fat:** <1% (essentially lipid-free). **Carbohydrates:** <1% (negligible). **Minerals:** Sodium ~200–500 mg/100 g (varies by manufacturer processing); trace amounts of calcium (~30–50 mg/100 g), phosphorus (~20–40 mg/100 g), and potassium; generally low in heavy metals (mercury <0.1 ppm, cadmium <0.1 ppm per specification). **Vitamins:** Not a significant source of any vitamins. **Calories:** ~350–380 kcal per 100 g (from protein alone). **Moisture:** Typically 5–8%. **Bioavailability notes:** The low molecular weight (~1000 Da) of Naticol 1000 is specifically engineered for high intestinal absorption; studies on similar fish collagen hydrolysates demonstrate >90% absorption in the gastrointestinal tract. Pro-Hyp and Hyp-Gly dipeptides are resistant to further enzymatic degradation by dipeptidyl peptidase IV and are detected in human plasma within 1–2 hours post-ingestion, reaching peak plasma concentrations of ~20–60 nmol/mL at typical oral doses of 5–10 g. These peptides accumulate preferentially in skin tissue. The absence of tryptophan means Naticol should not be relied upon as a sole protein source. Standard recommended dose is 2.5–10 g/day dissolved in liquid.

Preparation & Dosage

No clinically studied dosages have been established for humans. Preclinical mouse studies used oral supplementation (exact mg/kg not specified). Product is standardized to >93% collagen protein, with the x3Peptide variant containing 25% tripeptides. Consult a healthcare provider before starting any new supplement.

Synergy & Pairings

Vitamin C, Hyaluronic acid, Ceramides, Astaxanthin, Vitamin E

Safety & Interactions

Naticol 1000 is generally well-tolerated with minimal reported side effects. Individuals with fish allergies should avoid this supplement due to its marine collagen source. No significant drug interactions have been documented, though concurrent use with anticoagulants should be monitored. Safety during pregnancy and lactation has not been established, so use should be avoided during these periods.
