Fischkollagen mit Graphit – Nahrungsergänzungsmittel. Welches Kollagen sollte man wählen?

Collagen derived from the connective tissue of fish represents one of the numerous variants of this structural protein, available in diverse supplementary formulations. As an oral dietary supplement, it is most commonly marketed in the form of softgel capsules or finely milled powder, fortified with a bioactive complex of compounds that enhance its endogenous biosynthesis and accelerate tissue repair mechanisms. Key synergistic constituents include: **biotin** (vitamin B₇, also referred to as coenzyme R), which plays a pivotal role in DNA replication and amino acid catabolism; **ascorbic acid** (vitamin C) and **tocopherol** (vitamin E) – potent antioxidants that scavenge reactive oxygen species, inhibit lipid peroxidation, and mitigate extracellular matrix degradation; **oligomeric procyanidins** extracted from *Vitis vinifera* seeds, demonstrating metal-chelating properties and the capacity to inhibit proteolytic enzymes (e.g., collagenases); **trace elements** such as zinc (a cofactor for over 300 enzymes, including matrix metalloproteinases) and selenium (a component of glutathione peroxidases), both essential for maintaining redox homeostasis. In cosmetic applications, fish collagen serves as an ingredient in **hydrating emulsions** (creams, serums) and **barrier-forming preparations** (protective ointments), where it functions as a humectant binding water molecules within the stratum corneum, as well as a **biomaterial** in advanced hydrocolloid dressings designed for chronic wound management (e.g., venous ulcers) and second-degree burns. Morphologically, its fibrillar structure does not significantly differ from mammalian collagen (e.g., porcine) in terms of fiber diameter or spatial organization, as confirmed by electron microscopy studies. However, it is critical to note that **robust meta-analyses are lacking** to substantiate the efficacy of oral fish collagen supplementation in alleviating osteoarthritis or joint inflammation symptoms – in these contexts, **hydrolyzed porcine gelatin** (type I/III) yields superior clinical outcomes. It is also important to highlight that the complete regeneration of collagen networks in tissues (e.g., skin, tendons) requires a **minimum 36-month turnover cycle** due to the slow replacement rate of structural proteins, with collagen constituting approximately **30% of the total peptide pool** in the human body. Manufacturers typically withhold disclosure of **source fish species** (often byproducts of the filleting industry, such as salmon, cod, or tuna), which complicates allergenic risk assessments for consumers with shellfish hypersensitivity.

This formulation takes the form of a dark grey gel designed for topical application across a diverse range of regenerative and cosmetic uses, functioning as: a supportive agent for joint and tendon repair processes; a specialized cream formulated for intensive care of hyperkeratinized skin areas, particularly those subjected to mechanical stress such as the feet; a nutrient-rich hair mask with revitalizing properties; and a cosmeceutical preparation aimed at diminishing the visibility of wrinkles and scars of various etiologies. The precise chemical composition and recommended application protocols may vary significantly depending on the specific manufacturer and product line. Core active ingredients include: hydrolyzed collagen peptides, purified water serving as a vehicle, stabilizing complexes ensuring formulation longevity, 2-hydroxypropionic acid (commonly referred to as lactic acid) acting as a natural preservative and pH modulator, and melanin—a pigment responsible for the preparation’s distinctive coloration and its potential photoprotective characteristics.

The most significant and widely accessible dietary sources of collagen include a variety of broths, concentrated extracts, and gelatinous dishes prepared from ingredients such as shark cartilage, chicken feet (including wings and legs), offal (kidneys, liver), fish heads (particularly salmon and cod), as well as pork knuckles and beef shanks. Particular attention should be given to gelatin-based fruit desserts derived from pork gelatin, which not only serve as a palatable treat but also represent a valuable dietary supplement—especially for physically active individuals, such as athletes, whose demand for amino acids essential for collagen synthesis is elevated.
