Collagen is one of the most prevalent protein in the human body. It’s present in our connective tissue, ligaments, skin, muscles, bones, and blood vessels, and it’s critical to our general structural integrity. Manufacturers acquire marine collagen protein from sea creatures, as the name implies. The majority of marine collagen products on the market are derived from fish scales, bones, and skin. As a result, marine collagen is also known as fish collagen peptides. The fish’s meat is removed, and its skin is extensively washed in order to obtain collagen. The skin of the fish is then hydrolysed using acid and food-grade enzymes.

Here are some benefits of Marine Collagen:

  • May improve skin health: Sea collagen promotes skin health by releasing crucial amino acids required for the synthesis of collagen, which may help keeping the skin’s elasticity and firmness. In addition, marine collagen could include antioxidants that defend the skin against free radical damage, minimising the appearance of wrinkles, and nurturing a young complexion. Consumption of  marine collagen has been shown to support dermal thickness maintenance in mice by increasing the number and activity of tissue sections, or cells in the epidermis that create collagen and other fibres; human studies seem to back up this finding. But still need some extensive research.

  • May promote quality sleep: Glycine, the most prevalent amino acid in marine collagen, is believed to have sleep-supporting properties. According to one review of data, taking glycine before bedtime helped sustain sufficient levels of self-perceived good sleep. It was also hypothesised that glycine might help in the maintenance of core body temperature, which leads to improved sleep.
  • May support nail and hair health: The rising bioavailability of marine collagen, which comes from fish and shellfish, seems to be well known to promote the health of the hair and nails. It provides necessary amino acids that are important for the synthesis of keratin, the protein that gives hair and nails their strength and structure. Moreover, collagen may improve nail bed and scalp moisture retention, improving moisture retention and overall health. As bovine or porcine collagen has typically been employed in research in this subject, additional research is needed to support marine collagen.

The nutritional value of marine collagen as a supplement is currently being researched. Because our stomachs break down most foods before they are taken into our circulation, it’s unknown whether or not collagen supplements support our systems. It’s crucial to remember that supplements aren’t governed by the FDA, so if you’re considering taking marine collagen as a supplement, consult with your healthcare provider first to ensure it’s good for you.


Marine collagen is classed as Type I collagen, the most common kind of collagen found in human bodies, allowing people to get the biggest benefits. Whereas Type I collagen is the most abundant, marine collagen may also contain Type II and Type IV collagen, depending on the fish species and tissue sampled. Research published in Nutrients in March 2020 discovered that collagen peptides work as antioxidants in skin cells, limiting harmful free radicals and inflammation (both of which are related with chronic illnesses and ageing).

While collagen therapies began in skin care, the protein is too big to enter the skin for topical applications, according to Joshua Zeichner, MD, head of cosmetic and clinical research in dermatology at Mount Sinai Hospital in New York City. This is why some formulas utilise collagen peptides or partially broken down hydrolyzed collagen. Similar results occur when you consume collagen. According to Dr. Zeichner, the amino acids that are produced when the protein is broken down and circulated in the blood may signal the skin to increase the formation of fresh collagen. It is yet uncertain if this is true and how beneficial it is.

Again, It’s crucial to remember that marine collagen  supplements aren’t governed by the FDA, so if you’re considering taking marine collagen as a supplement, the best course of action is to speak with a healthcare provider before starting any supplements, especially if you are already taking any medications or have any medical conditions. 


In terms of the correct dosage of Marine collagen, medical organisations have not issued any formal guidance on how much collagen to take each day. As a result, the amount of collagen you should take varies on the type and objective for which you’re taking it. Follow the dose recommendations on the packaging if you wish to try the marine collagen. Packaging for powdered supplements frequently advises taking 1-2 scoops (or tablespoons) daily, but packaging for pills or gummies may advise taking 1-2 pieces.  Check the nutrition facts label for accurate dose information as the collagen concentration of these servings might vary greatly depending on the supplement.

Additionally, it’s recommended to see your doctor first to ensure that any supplement you take is safe for your particular health issues. Choose trustworthy providers that utilise wild-caught fish and have their certifications validated by a third party to verify that the products you are consuming are pure and contain just the ingredients that are demonstrated.
