What are the potential side effects of marine collagen?


Marine collagen supplements use collagen taken from the skin and scales of fish. Type I collagen is present in marine collagen peptides, which makes up around 80 per cent of the collagen in the skin. However, although high-quality marine collagen supplements do not come with many side effects - it is always useful to be aware of the potential side effects of marine collagen.

Here, we explore the key benefits and potential side effects of marine collagen, as well as any dietary requirements you need to consider before taking it.

What are the benefits of marine collagen powder?

Marine collagen powder supplements may be more effectively absorbed into the body than other forms of marine collagen since you may have a harder time digesting tablets and capsules. Hard casings, fillers, binders and other benign ingredients are often found in tablets and capsule forms of oral collagen supplementation.

Powdered marine collagen supplements may have even more potency if the collagen has been hydrolysed. This means that the collagen proteins have been separated into smaller pieces called peptides. Marine collagen peptide supplements may be more bioavailable and can be absorbed directly into the bloodstream. Find out more about the benefits of hydrolysed collagen supplements here.

Another benefit of choosing a marine collagen powder supplement is mixability. Popular ways of taking marine collagen powders are to mix them into cold drinks, such as water or smoothies. This versatile method allows for high dosages of marine collagen peptides within everyday foods that may lack nutritional value.

What are the possible side effects of marine collagen?

As a nature-derived supplement, marine collagen has minimal side effects. However, here are some rare but possible side effects of fish collagen supplements:

  • Minor bloating
  • Diarrhoea or constipation
  • Indigestion or heartburn
  • An allergic reaction (hives, itching, rashes).

Although experiencing side effects from taking marine collagen is rare – it is important to always do research into a product before taking it and ensure that you don’t have any allergies or conditions that may heighten the risk of side effects.

The risk of side effects can also be minimised by ensuring you take the recommended dosage and following any guidance from the manufacturer.

When should you avoid taking marine collagen powder?

If you’re allergic to fish or shellfish, marine collagen powder is not suitable for you. If you have any health conditions such as hyperthyroidism and therefore have restrictions on seafood foods, this collagen supplementation product isn’t for you either. Additionally, if you’re on a vegetarian or vegan diet, you may consider vegan collagen instead. Read our guide to marine collagen vs vegan collagen supplements here.

Additionally, you must consult your healthcare professional before taking any supplements if you are pregnant or breastfeeding.

It is also important to consult your healthcare professional or pharmacist to get advice on when is the best time to take marine collagen supplements to avoid drug-drug interactions.

Powdered forms of marine collagen supplements, such as Beauty Complex, can make a refreshing drink and are effectively absorbed by the body. They also often contain no fillers and can be a perfect option if you don’t like taking tablets.

Marine collagen, often known as fish collagen, is usually taken from the skin and scales of cod. Marine collagen can be sourced from wild-caught fish or farmed fish. Read about choosing natural marine collagen supplements here.
