Collagen is the most abundant protein in the body, constituting approximately one-third of the total protein composition. It is vital for healthy skin, nails, and hair, and it provides structure and suppleness to the skin.

As we age, collagen production decreases, resulting in wrinkles, sagging skin, and other apparent indications of aging. Collagen supplements are an option for addressing this issue.

In recent years, liquid marine collagen has become increasingly popular as a dietary supplement. So, what is liquid marine collagen, and what are its possible health advantages and risks? Let’s find out.

What is Marine Collagen?

Marine collagen is a form of collagen isolated from fish and shellfish skin, bones, and scales. In contrast to bovine and porcine collagen, it is high in type 1 collagen, the most prevalent kind of collagen in our bodies.

It has a low molecular weight, making it also more readily absorbed by the body. [1] Because of its potential health advantages, marine collagen is frequently included in nutritional supplements and skin care products.

How Does Marine Collagen Work?

When marine collagen is ingested, it is broken down into peptides that are more easily absorbed by the body. These peptides encourage the synthesis of new collagen, elastin, and hyaluronic acid. Thus, enhancing the health of our skin, hair, and nails. They also play a role in supporting joint health and reducing inflammation. [2]

Benefits of Liquid Marine Collagen

1. Liquid Marine Collagen for Improved Skin Health

Collagen serves as a framework that supports the fullness of our skin and keeps our faces looking youthful. Yet, collagen production always slows with age, therefore collagen supplements can help keep skin looking younger. It also can potentially lessen the visibility of fine lines and wrinkles.

Based on several studies, using marine collagen supplements has been demonstrated  to positively affect skin health by enhancing skin hydration, elasticity, and firmness. [3]

According to research, after taking a supplement containing hydrolyzed Type I collagen derived from tilapia, women saw improved skin support, less visible wrinkles and photoaging, and improved moisture levels. [4]

2. Liquid Marine Collagen for Joint Health

Collagen is an essential component in our joints, and supplementation with marine collagen may alleviate joint discomfort and inflammation.

A research on athletes showed that taking collagen supplements decreased joint discomfort and enhanced joint flexibility. [5] While studies are limited, liquid marine collagen shows promising results in preventing muscle damage, easing joint pain, and increasing muscular mass.

3. Liquid Marine Collagen for Stronger Nails and Hair

As collagen is deposited directly in hair follicles and nails, supplementing with collagen peptides can promote hair and nail growth without interfering with the body’s ability to produce collagen for vital organs.

Also, it is possible that marine collagen might help strengthen nails and hair by stimulating the development of keratin, which is a protein that is required for the growth of both hair and nails. [6]

4. Liquid Marine Collagen for Gut Health

Leaky gut is a complicated health problem that happens when the lining of the gut is damaged and can’t work as a barrier in the way it should.

Marine liquid collagen is great for gut health because it helps with digestion, repairs the lining of the gut, and can help heal IBS and leaky gut syndrome. By encouraging the development of good gut flora, marine collagen may play a role in improving gut health. According to a research, consuming collagen supplements helped lessen leaky gut syndrome symptoms. [7]

Collagen is the most common protein in the human body, but we make less of it as we get older. As a result, taking a collagen supplement may aid in reestablishing healthy collagen production and promoting gut repair.

5. Liquid Marine Collagen for Heart Health

Researchers believe collagen supplements may help lessen the risk of heart issues because collagen provides structure to your arteries.

Reduced collagen levels have been linked to reduced elasticity and flexibility in the arterial wall. This can cause atherosclerosis, which causes your arteries to harden and narrow. Heart attacks and strokes are potential outcomes of this illness. [8]

Collagen has been shown to improve HDL (good) cholesterol and decrease measures of arterial stiffness. HDL plays a significant role in determining the likelihood of developing cardiac diseases, including atherosclerosis. [8]

However, further research is required to fully understand the relationship between collagen supplements and cardiovascular wellness.

Does Marine Collagen Really Work?

Increasing data suggests that marine collagen supplements may offer health benefits, including enhanced skin, joint, nail, and hair health. Clinical studies have also demonstrated that a collagen supplement can reduce the body’s breakdown of its own collagen. [9]

However, further research is required to completely comprehend its usefulness and potential adverse effects.

Is Liquid Marine Collagen Good for You?

For people wishing to enhance the health of their skin, joints, hair, and nails, liquid marine collagen can be a helpful supplement.

What’s more, it may improve digestive health. But like with any dietary supplement, you should consult a doctor before using it, especially if you have any underlying medical conditions or are taking any drugs.

Can You Take Too Much Collagen?

Collagen is typically regarded as a safe and harmless daily supplement for healthy people. Most people will not encounter any negative side effects.

Too much collagen, however, can disrupt the body’s amino acid balance, causing unpleasant symptoms like headaches, gastrointestinal distress, and exhaustion. Several people have complained of side effects like a bad aftertaste, bloating, heartburn, and other digestive problems.

Liquid Marine Collagen Risks

Although liquid marine collagen is generally safe, it is necessary to be aware of its potential side effects. Those with a fish allergy may experience stomach difficulties and allergic reactions.

To assure safety and efficacy, it is also crucial to get supplements from reputed manufacturers.

Side Effects of Liquid Marine Collagen

Although liquid marine collagen is usually considered harmless, certain individuals may experience unwanted side effects when taking liquid marine collagen.  They could include gastrointestinal problems such as bloating and diarrhea.

Supplements containing marine collagen should not be taken by anyone who is allergic to fish. Before ingesting any new supplement, it is crucial to consult a healthcare provider.

Bottom Line: What is Liquid Marine Collagen? 5 Helpful Benefits & Its Risks

Liquid marine collagen is a dietary supplement that can improve the health of the skin, joints, and bones. Its hydrolyzed structure makes it easier for the body to absorb, and its amino acid makeup confers several health benefits.

Nonetheless, it is essential to be aware of the possible side effects and hazards associated with liquid marine collagen consumption.

Before beginning a new regimen or experimenting with liquid marine collagen, it is always advisable to consult with your doctor to ensure that it is safe and useful for you.
