Marine Collagen: Benefits in Skin Elasticity, Hair, Nails, Joints, and Bone Health

Introduction

Ageing is closely related to collagen degradation, which affects the structure and strength of the muscles, joints, bones, and skin. Skin ageing is a natural and continuous process affected by extrinsic factors like exposure to UV radiation, dietary habits, smoking and cosmetic supplements. Taking supplements that contain collagen can help restore youth and vitality to the skin and remedy the signs of ageing. Collagen supplements are enriched with essential amino acids like proline and glycine that counter the ageing process. [1] 

Different bioactive marine peptides have various anti-aging properties, such as free radical scavenging, inhibition of apoptosis, extension of lifespan in various organisms, and protective effects in ageing humans. Besides, the topical application of hyaluronic acid is proposed to enhance collagen and moisture production in the skin, thus playing a role in the anti-aging effects of collagen supplementation. Bio-tissue engineering of marine collagen applications is also discussed, with emphasis on its proven usefulness in skin healing and bone regeneration applications. [1] 

In this blog we will explore what marine collagen is, how it works in the body, its benefits for skin, hair, nails, joints and bones and what current research suggests about its role in encouraging healthy skin and overall well-being. 

What is Marine Collagen?

Marine collagen is a natural occurring structural protein derived mainly from fish skin, scales and bones. Once extracted it is enzymatically hydrolysed, which is to say large collagen molecules are broken down into smaller pieces, called marine collagen peptides or hydrolysed marine collagen. [2] 

These smaller peptides are more easily digested and absorbed than intact collagen proteins and after ingestion are efficiently transported throughout the body. 

Marine collagen is mostly type I collagen, the most abundant type in human skin, whereas bovine collagen contains both type I and type III collagen. Type I collagen provides the strength, firmness and structure to the skin. That’s why marine collagen is so popular in beauty and skincare supplements.

Marine Collagen Benefits

Marine collagen is gaining popularity because it offers several benefits, as it is a low molecular weight peptide, making it highly available. A good source of type-I hydrolysed collagen dissolves readily in liquids.  

How Does Marine Collagen Work? 

Marine collagen is particularly rich in the amino acids; glycine, proline and hydroxyproline, which are essential building blocks for collagen synthesis. It helps the body produce its own collagen instead of replacing lost collagen. When hydrolysed marine collagen peptides are ingested, they undergo further digestion in the gastrointestinal tract and break down into smaller peptides and amino acids. 

The nutrients are absorbed through the small intestine into the bloodstream and taken to different tissues, such as the skin, joints, bones, tendons and ligaments

Mode of Action:  

The mode of action of marine collagen involves high systemic bioavailability from low molecular weight peptides that easily enter the bloodstream after oral intake, acting as building blocks and signalling molecules that stimulate fibroblast proliferation, enhance antioxidant defences, and promote extracellular matrix synthesis in skin and bone tissues.

Benefits of Collagen for the Skin

Collagen makes up 70–80% of the dry weight of the skin and provides the dermis its mechanical and structural integrity. [3] This collagen network acts as a scaffold providing firmness, resilience and elasticity while helping to maintain a smooth and youthful appearance. 

As we age, our body produces less collagen, which gives our skin its structure and support. This leads to wrinkles, sagging, dryness and uneven texture. 

Marine collagen supplementation may contribute to the maintenance of healthy skin as follows: 

Clinical studies have demonstrated that regular supplementation of collagen peptides can improve skin hydration, elasticity and general appearance but results can differ from person to person depending on age, lifestyle and general health.

Skin elasticity 

Skin elasticity is the skin’s ability to stretch and return to its original shape. Healthy skin is firm, stretchy and youthful-looking. The two main proteins that keep the skin elastic are collagen and elastin. Elastin provides skin elasticity, while collagen forms the structural framework that supports the skin and helps maintain its firmness and resilience. 

With age and exposure to environmental factors such as ultraviolet (UV) radiation, collagen fibres become fragmented and disorganised. This gradual breakdown reduces the skin’s ability to hold its shape, leading to sagging and laxity. 

Marine collagen may help to support skin elasticity by: 

Regular supplementation along with a healthy diet and proper skin care may help to promote healthier skin as part of the natural ageing process.

Wrinkles 

As we age, collagen and elastin fibres decrease and wrinkles form. It is accelerated by repeated facial expressions, UV exposure, smoking, pollution and oxidative stress leaving you with fine lines and deeper wrinkles. 

Marine collagen peptides contain amino acids that may help improve the structural support of the skin and support natural collagen synthesis. 

These may have the following benefits: 

Marine collagen is not a replacement for sunscreen or a complete skincare regimen, but it could be a nice complement to healthy lifestyle habits that will promote skin ageing from the inside out. [4]

Hair Growth  

A healthy scalp and healthy hair follicles are key to healthy, strong hair. Keratin is the primary building block of hair, but collagen has an important (though indirect) role in the environment that supports healthy hair growth. 

Marine collagen contains amino acids including glycine, proline and hydroxyproline that are necessary for the formation of proteins and connective tissues surrounding hair follicles. It helps in keeping the scalp structure intact which in turn promotes the growth of healthier hair. 

Potential benefits of marine collagen for hair may include: 

Another factor associated with hair ageing is oxidative stress. Marine collagen may help support the body’s natural collagen network and healthy connective tissues, which may contribute to maintaining healthier hair when consumed as part of a balanced diet and healthy lifestyle. 

But marine collagen is not a treatment for hair loss disorders, it can help to keep your hair in good condition overall when you have a balanced diet and look after your hair well. [5]

Stronger Nails

Just like skin and hair, nails too undergo age-related changes. Brittle nails, thin nails, and splitting nails are all common problems, especially as we age and collagen production slows. 

Marine collagen may help nail health by providing amino acids involved in the upkeep of healthy connective tissue around the nail matrix, the place where new nail cells are created. 

Potential benefits are: 

Regular use of collagen peptide supplements has been shown to improve nail strength and reduce the incidence of broken or chipped nails in several studies.

Joint Wellbeing

Marine collagen is famous for its benefits to the skin but collagen also plays a vital role in keeping your joints and connective tissues healthy. Collagen is a major structural protein in:

Cartilage, Tendons, Ligaments, Joint capsules  

These tissues act as shock absorbers to the mechanical stress of movement and provide flexibility to the joints. With age your body naturally loses collagen and cartilage can lose its elasticity over time, which can lead to stiffness and decreased mobility. 

Marine collagen peptides may help support: 

Maintaining healthy collagen levels may be important for the long-term joint health of the physically active and seniors.

Bone Health

When we think of bones, we think of hard mineral structures. But collagen makes up about a third of bone tissue. The collagen scaffold gives bone flexibility and provides a framework on which minerals such as calcium and phosphorus can be deposited. 

Healthy collagen helps to: 

As we get older, our bodies make less collagen. This may help lower the quality of our bones. Healthy ageing involves supporting collagen synthesis with a nutritious diet, regular weight-bearing exercise and collagen supplementation to help maintain bone health. 

Marine collagen should be considered as one part of a total bone health strategy that includes adequate calcium, vitamin D and regular physical activity.
