There are a number of different collagen supplements available on the market, but marine collagen has become the most sought after.

What Is Marine Collagen?

Collagen is a type of protein in the human body that is found in various connective tissues. It plays an important role in the health of our connective tissues as well as skin, cartilage and bones. 

Marine collagen is a type of collagen made from peptides that originate in fish. It is typically sourced from the skin and scales of fish. Marine collagen is incorporated into supplements to help boost collagen in the body. It has the highest source of bioavailability in collagen supplements. 

Other types of collagen supplements exist such as bovine collagen but marine collagen has become the most desirable due to the type 1 peptides present in the substance that are thought to be best for skin and bone health.

Benefits Of Marine Collagen Supplements

Due to the fact that collagen is a naturally occurring substance in the body, there is ample evidence to prove its effects on the body and the necessity of collagen in connective tissue health. Marine collagen, whilst being derived from fish, works in a similar manner when ingested in supplement form and there are a wide variety of scientific investigations that claim it has positive effects on skin, bones, and connective tissues such as muscles, joints and even organs.

Skin Health

As we get older, natural collagen in the body begins to decrease. This can result in a reduction in our skin health, leading to dryness, wrinkles and increased chance of issues with our skin. Marine collagen supplements can be a great method for boosting collagen in the body to reduce and prevent the effects of ageing on the skin. 

A number of studies have concluded that this supplement can have anti ageing effects and increase skin hydration and elasticity. 

Bones and Cartilage

Bones and cartilage are yet another part of our bodies that become weaker with age. As we get older, we’re at risk of developing conditions that damage and weaken our bones and joints like arthritis and osteoporosis. Scientists have determined that marine collagen could help fight against bone disorders and improve overall bone health. The fish collagen promotes cell growth as well as collagen and mineral development which helps maintain bone strength.

This therefore helps to reduce issues like broken bones and weak joints as well as manage the painful symptoms of bone, joint and cartilage disorders.


If you’re looking for thick, long hair or you’re wanting to retain your hair as you age, then marine collagen could be the perfect treatment for healthy hair. Fish derived collagen can significantly enhance hair growth as well as stimulate and encourage growth in areas where hair has already been lost. This makes it an ideal preventative supplement as well as an effective method of treatment for hair loss. 


Have you got dry or brittle nails? Maybe you have a hands on job that exposes you to more nail breakage? Marine collagen vitamins might just be able to keep your nails looking fresh and intact. The strengthening properties of the amino acids present in collagen mean that you might see an improvement in the durability and thickness of your nails when taking these vitamins. 

Wound Healing

If you’re someone who often finds themselves with minor scrapes or scratches or is suffering from a wound, then marine collagen could be great in helping you  heal. This type of  collagen has been found to have regenerative properties and studies have indicated that it might even be an effective biological substance to eventually use in clinical settings.

Skin Conditions

With many different skin conditions like eczema and psoriasis, the number one method of combating symptoms is to keep skin hydrated whilst managing any irritation. If your skin condition doesn’t require antibiotics or you’d prefer to try a more natural remedy then you might want to try marine collagen as part of your skin management routine. 

The substance has been found to greatly increase skin hydration, meaning that you could see a decrease in dry skin symptoms as well as an increased possibility of healing from the previously mentioned wound healing properties. 

Muscle Growth

Whether you’ve got reduced muscle mass, muscle weakness due to old age or you’re looking to boost your muscles and get fit, marine collagen can work wonders. 

Used in conjunction with exercise, marine collagen supplements can increase muscle mass, strength and mobility. So if you’re struggling to grow your muscles, this handy supplement could give you a natural boost.

Gut Health

Many of us suffer from sensitive stomachs or more serious gut problems like IBS, IBD, Crohn’s disease and UC. If you’re tired of the discomfort and difficulty in managing these disorders then marine collagen could lend a helping hand and improve your gut wellbeing. A large amount of the gut is made from connective tissues, so for starters it would make sense that collagen could help improve gut health since our body naturally produces the substance to strengthen connective tissues. 

Marine collagen has been found to improve intestinal barrier dysfunctions. It also contains amino acids such as glycerine that are known to help reduce inflammation so it may help to settle the inflammation that causes the more frustrating symptoms in irritable bowel syndrome and disease.

Marine Collagen Side Effects

Like most natural supplements, side effects from marine collagen are very rare and are usually only very minor. The less serious possible side effects are an upset stomach or constipation, bloating or feelings of indigestion and heartburn. 

The more serious side effect is an allergic reaction. It is important to note you should not take marine collagen under any circumstance if you are allergic to fish or shellfish. If you ever experience a rash, swelling or any other allergy symptoms be sure to consult a medical professional immediately. 

How do I take marine collagen image showing supplement capsules

How Do I Take Marine Collagen?

You can intake marine collagen in a number of different ways including in powder, liquid and supplement form. It can also be an active ingredient in skincare and haircare products.

You can take supplements of marine collagen in capsule form with a glass of water each day. Always follow dosage instructions provided by each brand you purchase your supplements from. 

If you’re wanting to take marine collagen in powder form, the most common method is to mix it into drinks. This can be any drink of your choice but it is usually something with flavour like soft drinks or smoothies or even tea or coffee if you’d prefer. It can also be used in foods but this is often unnecessary as the taste of the powder itself is easy to tolerate and it is easier to absorb by simply ingesting in liquid form.

You can also buy collagen in a premade flavoured formula. This is usually deemed a liquid dietary supplement and is taken as a few spoonfuls or a measured cap full of liquid daily. Again, dosage levels vary with manufactures so be sure to follow instructed amounts.

How Often Can I Take Marine Collagen?

There are currently no standardised guidelines regarding the dosage of marine collagen, but there are usually different advised doses based on the form of collage you are taking. Different companies also have different strengths of supplements and these doses vary across the board. 

For powdered marine collagen, it is advised to take between 1-3 scoops or sachets of product each day, whether that be mixed in with drinks or supplemented into food. 

Most supplements are usually marketed as a one a day supplement and will provide you with your dose of marine collagen in one capsule. You can however also buy capsules that can be taken up to 4 times a day.

Whilst there is no clear dosage in grams or milligrams of how much is too much marine collagen, taking more than the recommended dosage of each product can increase the chances of stomach side effects so it’s best to stick to what’s instructed.

How Long Should I Take Marine Collagen For?

Collagen production in the human body starts to slowly decrease when we hit our 20s and gradually decreases throughout our lives. The visible and physical effects of decreased collagen such as wrinkles, bone and joint issues begin to show themselves once we reach our 40s. 

In terms of taking marine collagen, there has been no maximum period studied and many people believe that it should be a long term supplement to continue to supply the body with collagen as we slowly stop producing it.

In terms of minimum time frames the majority of studies found positive results in trials lasting 12 weeks, with positive effects on the skin being evident at around week 6. Therefore it is most commonly recommended to take marine collagen supplements for at least 6-12 weeks if you want to notice any benefits and then continue on from here. 

Who Shouldn’t Take Marine Collagen Supplements?

When it comes to marine collagen supplements, the main reason that people might not be able to take them is due to the fact they derive from fish. There is no scientific evidence that these supplements  interfere with any medical conditions and there are no known drugs that interact with marine collagen.

Do not take marine collagen if:

  • You have fish or shellfish allergies 
  • You are vegetarian or vegan

Any individuals that cannot consume fish for dietary or religious reasons should avoid marine collagen or consult a specialist before beginning to take the supplements.
