Fish derived collagen peptides are receiving more and more attention due to their favourable characteristics and fewer consumer reservations compared to mammal-derived ingredients.

Seagarden has developed a production line for marine-based collagen peptides to cater the growing demands of the nutraceutical and cosmetic industries worldwide. Nutricoll Nordic Marine Collagen is exclusively produced from deep-sea cod skin (Gadus morhua), harvested from the crystal clear waters of the North Atlantic Ocean. This provides the purest source of high quality and 100% natural collagen peptides available on the market.

Nutricoll Nordic Marine Collagen stands out due to its low molecular weight resulting in improved digestibility and increased bioavailability. Nutricoll Nordic Marine Collagen is the ideal bio-active ingredient to include in a wide range of applications for health, sports, beauty and cosmetics. 

Seagarden offers Nutricoll Nordic Marine Collagen peptides with an average molecular weight of 3000 Da and 6000 Da. 1000 Da is an abbreviation for 1000 dalton which describes a unit of molecular mass consisting of 1000 daltons and it is the standard unit used to represent the weight of large molecules such as proteins. The 3000 Da variant has smaller particles and lower molecular weight and thus better bioavailability compared to 6000 Da. This variant is therefore suitable for tablets and stronger flavoured products as the taste is more profound. Nutricoll Nordic Marine Collagen of 6000 Da has almost no taste and smell and is therefore excellent to use in natural pure products.

Collagen peptides are a hydrolysed form of collagen, which is a unique oligopeptide supplying the necessary amino acids for the development of collagen in human connective tissues and skin. Through an enzymatic hydrolysis process, the product loses its gelling effect and becomes water-soluble. 

Collagen peptides are highly digestible and suitable as an oral supplement. Studies show that collagen peptides have a better bioavailability in the human body than gelatine, due to the difference in molecular size. Our product is suitable for those who do not use collagen from traditional bovine and porcine sources. 

Clinical studies recommend a daily dose of 10 g, for a minimum of three months, for best effect. Followed by a daily maintenance dose of 5 g. Since it is readily soluble in water, it can be mixed with beverages such as water, juice or other liquids, or in foods such as yoghurt, porridge or cereals.

Proline is the precursor of hydroxyproline, which is involved in the formation of collagen, tendons and ligaments. Proline is therefore important in the treatment of osteoarthritis. Proline is depending on vitamin C for the formation of collagen. The proline productions in the body increases for instance with injuries and after exercise where it builds up damaged muscle fibres. This means that marine collagen peptides can be helpful in the restitution phase after exercise.

Hydroxyproline is the hydroxylation of proline and it is depending on vitamin C. Therefore, lack of vitamin C could give unstable collagen molecules and affect collagen in the body.

Several studies have proven the impact of marine collagen peptides on personal appearance and the musculoskeletal system.

Anti-aging effect on human skin

Marine Collagen hydrolysates has an anti-aging effect on human skin. A recent clinical trial demonstrated a significant increase in skin elasticity in a group of women aged 35-55 years (1).

Reducing skin wrinkles

The same group of scientists from the University Of Kiel, Germany, also demonstrated a significant reduction in skin wrinkles after daily consumption of a collagen hydrolysate (1).

Increasing the skin moisture level

A comprehensive study of the effect of oral collagen peptide supplement on skin-aging involving clinical trials with Japanese and Caucasian women showed good effect on skin moisturisation. The fish collagen peptides were shown to increase the skin moisture level by 12% in a period of 8 weeks. A consistent increase in the skin collagen density over 12 weeks was confirmed by increased dermal echogenicity. Ex vivo studies confirmed the results of the clinical trials and showed an increased amount of water-binding glycosaminoglycans and collagen content in human skin explants incubated with fish collagen peptides(2).
