Wondering what exactly marine collagen is? Perhaps you know what it is, but you’re not sure what it can do for you. In other words, what are the health benefits of hydrolyzed marine collagen peptides? Marine collagen, which comes exclusively from fish, has numerous health benefits, especially beauty benefits. These include helping to reduce the appearance of wrinkles and scars, possibly helping in stabilizing blood sugar, reducing inflammation, and so much more. Marine collagen is easily absorbed and highly effective. It’s here to help you fight aging from the inside out. It’s also great for pescetarians too! Here we provide everything you need to know about what is marine collagen

What is Marine Collagen?

Collagen is the most abundant protein in our body, yet our bodies produce less and less of it with each passing year. Since most of us don’t get enough collagen through our diets, supplementing with a quality source of collagen peptides is essential to keeping our bodies strong and healthy. This is where Marine Collagen Peptides can help. There are lots of marine collagen peptides benefits.

Collagen peptides can come from different sources, including bovine and other animals. Marine Collagen Peptides are derived entirely from fish collagen, either fish skin or scales. The unique composition and structure of Marine Collagen Peptides provide numerous health benefits as explained below.

1. Marine collagen is highly bioavailable

One marine collagen benefit is that it has superior absorption and bioavailability.  Marine collagen has the smallest particle size and lowest molecular weight among all collagen types, which allows it to pass through the intestinal wall into the bloodstream more easily to provide better healing, repair, and nourishment. Marine collagen is absorbed up to 1.5 times more efficiently than other types of collagen, making it one of the best and effective types of collagen.

2. Type 1 Collagen

Another marine collagen peptides benefit is that it is mostly made up of Type 1 Collagen. There are over forty different types of collagen throughout the body that vary in their composition and function, but Type 1 collagen is the most abundant collagen in our body. Marine collagen consists almost entirely of Type 1 collagen, which is an important component of skin, bone, teeth, muscles, tendons, ligaments, and fascia.

3. Rich in the amino acids glycine and proline

An important marine collagen benefit is that it provides 8 out of 9 essential amino acids, including substantial amounts of glycine and proline which perform important functions throughout the body. Glycine is an all-encompassing amino acid that promotes the building of lean muscle mass, impacts the central nervous system to prevent the formation of stomach ulcers, has anti-inflammatory and antioxidant properties, and improves glucose tolerance to protect against diabetes. Proline is important for stimulating collagen synthesis and works as an antioxidant by scavenging free radicals to prevent cell damage.

4. It’s environmentally friendly

A marine collagen benefit that you might not know is that marine collagen is the most environmentally sustainable source of collagen. An estimated 60% of by-products of fish processing become waste1, but researchers recently discovered that these by-products, especially the collagen-rich fish skin, have amazing health-boosting properties. Additionally, marine collagen made from fish skin helps to reduce environmental pollution, and provides a superior and beneficial source of collagen protein..

Marine Collagen Benefits For Health and Beauty

As we age, our body’s ability to produce new collagen declines, and existing collagen begins to break down. This loss of collagen is the root of aging of our skin, joints and bones, and this diminished supply can lead to increased digestive problems, a weakened immune system, and increased risk of chronic illness.

Fortunately, science has shown that collagen supplementation may protect against and reverse these effects. There are lots of benefits of marine collagen powder. Here are 8 benefits of marine collagen supplements:


The loss of bone mass is one of the most common signs of aging and can lead to osteoporosis, which affects over 75 million people throughout the U.S., Europe, and Japan. Making sure we have enough calcium and phosphorus is essential to maintaining bone strength. However, these minerals are difficult to absorb, resulting in deficiencies and putting us at risk for bone loss and bone disease. Studies have shown that marine collagen peptides may help the absorption of calcium and other minerals that are essential for bone strength.

Additionally, marine collagen supplementation may stimulate collagen synthesis in the bones by promoting bone-building cells, called osteoblasts,3 that build the organic matrix of bone, which is 90% collagen.


The collagen in our skin begins breaking down at age 21 and continues to be degraded throughout adulthood, leading to saggy, wrinkly skin as we get older. 70% of our skin is made of Type 1 collagen, and supplementing with Marine Peptides, which are a Type 1 collagen, may help to replenish our skin and may even help to reverse aging. Clinical trials have shown patients who supplement with marine collagen have a decrease in wrinkles and improved skin hydration and firmness.4,5


Marine collagen has a unique amino acid composition with higher glycine levels than any other types of collagen. Scientists are continuing to discover the beneficial roles of glycine throughout the body, specifically in relation to supporting healthy blood sugar levels. Recent research has found a connection between low blood glycine levels and impaired glucose tolerance, which suggests low glycine may lead to insulin resistance and ultimately diabetes. In fact, a 2016 study by the Alberta Diabetes Institute found consistently low levels of circulating glycine among people with type 2 diabetes.6


Marine collagen supplementation has been shown in clinical trials to lower LDL (the bad lipoprotein) and increase HDL (the good lipoprotein)7. HDL is the “good” lipoprotein that pulls cholesterol and triglycerides out of the blood and tissues to help prevent tissue damage caused by fats. It is believed that marine collagen peptides may help promote genetic factors that regulate lipid metabolism and control cholesterol levels.


Supplementing with marine collagen may lead to faster and more complete healing of wounds. As the main component of the dermal matrix of the skin, collagen is necessary for regeneration of skin after any skin injury or deformation, such as scars, rashes, and burns. Supplementing with marine collagen peptides may be an important component of wound healing by helping to promote cell proliferation, protein synthesis, and regenerating the extracellular matrix for tissue strength.


Bioactive peptides from marine sources, including hydrolyzed marine collagen, have antioxidant properties that can reduce the presence of reactive oxygen species throughout the body.9 Reactive oxygen species cause aging of tissues, higher risk of cancer, and inflammatory responses throughout the body. Antioxidants are an important protection against accumulation of reactive oxygen species and also help to boost the immune system. Studies have shown decreased levels of reactive oxygen species after treatment with marine collagen peptides, showing that supplementing with marine collagen may help to reduce inflammation.


Recent research has discovered that peptide fragments contained within marine collagen have antibacterial properties. Specifically, collagencin, a peptide derived from collagen, has been found to inhibit the growth of infection and disease causing bacteria. A 2016 study showed collagencin completely inhibits the growth of the common bacterium Staphylococcus Locus, commonly known as staph infection, and partially inhibits the activity of other bacteria, including E. Coli.10 The authors in the study concluded that marine collagens are a promising source of antimicrobial agents with positive implications on human health.

While the research is still ongoing, the ability to inhibit the growth of staph infection and E. coli through supplementation with marine collagen peptides could be a great alternative to antibiotics.


Marine collagen does not contain any carbs, sugar or fat. Daily intake of marine collagen may help to suppress appetite by keeping you feeling full longer and thus can help promote weight loss
