There has been an increased interest in products that contain collagen- a natural anti-ageing beauty secret. Not only is it considered to be an effective anti-ageing product for skin but also seems to show promise for alleviation of joint pain and inflammation and may be beneficial for wound healing. It also is a nutritious diet aid due to its amino acid profile [1].

Collagen is a fibrous and structural protein in our body and plays a role in formation, repair and maintenance of muscles, ligaments, joints, tendons, vital organs, skin, hair and nails. As we get older collagen production slows down and the diminishing stores can also manifest into joint pain, increased inflammation, saggy and wrinkly skin. Some clinical trials have shown marine collagen can reduce fine lines and improve skin elasticity within an 8 week period [2,3,4].

Not All Collagen Products Are Equal

Fish collagen is favoured over porcine and bovine collagen because it does not carry disease, is sustainably processed from parts of fish, which would have been discarded in the fish processing industry (fish scales and skin) and also has higher anti-bacterial and anti-oxidative properties. The marine peptides are also readily absorbed by the human body with no known toxic or adverse effects  [5].

Is Marine Collagen for You?

The ageing process kicks in around 30 years of age and skin begins to lose its plumpness and small lines start to appear. The ageing process is accelerated by too much sun exposure, chronic stress, pollution, smoking or poor diet. If you feel your protein intake has been inadequate and notice that your hair, skin and nails are in poor condition it might be worth a try.

Purchase pure marine collagen that contains no additives, fillers, artificial flavours or preservatives and look for wild harvested fish such as red snapper. This ensures that the product is free from heavy metals and antibiotics. Marine collagen is not for vegans or people with fish allergy.
