Collagen is the main protein found in the connective tissues of the body, which is abundant in parts like the skin, bones, ligaments, tendons, hair, and nails. They are responsible for giving structure, texture, toughness, and rigidity to these tissues (1).
As we age, our bodies naturally start making less collagen. The aging process is affected by many factors such as race, gender, physical activity, and nutrition. Poor nutrition accelerates aging by reducing our collagen levels, and this has led to the emergence of collagen supplements to level up dietary intakes (2).
Marine collagen is collagen supplement made from the skin of fish. It has becoming increasingly popular in recent years thanks to its numerous benefits (3).

Benefits

1. Like other collagen sources, marine collagen helps to retard the aging process, by supplying enough collagen to the body to combat wrinkling. It hydrates the skin and maintains the integrity of the skin structure (4).
2. Marine collagen helps the body synthesis elastin and fibrilin which give skin its elasticity. Elastin gives the skin its bounce and stretchy nature (5).
3. Collagen peptides have strong antioxidant properties, as such they capture bad atoms in the body called free radicals that cause oxidation and destroy cells (6).

4. Collagen peptides have been shown to have chemostatic properties for skin fibroblasts which helps in the healing or skin restoration process (9).

For ethical, moral and/or religious reason, some people do not eat animals. Vegetarians for example generally do not eat animals, or any products made from them. However, some like pescetarians eat fish and shellfish, hence, marine collagen will be a go for them (10).

Our Nutrimore Marine Collagen is white or yellowish in color and comes as powder or granule.  It is made from good quality marine codfish skin A or B and is very rich in proteins (at least 90%). It comes in a 20kg heat sealed PE bag, packed with a wire stitched kraft bag outside.
Most importantly, it has a very small molecular weight of 1000 Daltons. With such a small size, our Nutrimore Fish Collagen will be easily and quickly broken down and absorbed because the smaller the size of a molecule, the faster it is digested and absorbed into the body. Normal collagen is very large (30,000 Daltons) and so must be broken down into smaller molecules which can then be further broken down in our intestines with ease (11). Generally, fish collagen is considered high quality when its molecular size is less than 2000 Daltons, so our product has an even lower molecular weight, making it a very superior quality marine collagen.
Additionally, Nutrimore Marine Collagen has a shelf life of 24 months, thanks to its low moisture content (≤ 7.0) and can be stored easily (in a ventilated dry area). Powdered collagen should be dissolved in a regular glass of water and drunk, or added in smoothies, coffee, or any drink of your choice.
There is presently no health authority that has given guidelines on the dose of marine collagen required daily. However, thanks to clinical research studies, some doses have been estimated safe and effective depending on the need (12, 13, 14).

1. 2.5g – 15g/day is regarded as generally safe and effective.
2. A minimum of 2.5g/day is effective to promote general skin health, and skin hydration.
3. More than 15/day is effective to improve muscle mass. Muscle mass decreases the appearance of loose skin.

Our Nutrimore Marine Collagen is a great dietary supplement with potentials to improve skin health and slow down aging effects. The dose to take depends on the need of the person in question but generally a minimum of 2.5g daily is reported safe to generally promote skin health. Moderation is key and people with fish allergies may have to pass on this product.
