Finding the best marine collagen supplements


Collagen production declines more rapidly after we reach the age of 30 - this can result in potential changes to the appearance of the skin. For this reason, collagen supplementation is a popular option for its potential benefits in increasing collagen production.

Due to the popularity of collagen supplements, the market is saturated. It can be a challenge to choose the right product for your needs. This article will cover the types of collagen supplement and their relevant advantages. We will explore benefits of marine collagen, collagen peptides, powdered collagen supplements and finally, the benefits of a combined, powdered supplement.

Marine vs bovine collagen

Collagen is the most abundant protein in the human body, it is found in joints, bones, connective tissue and in our skin. As we age, the collagen level in our bodies decreases so it may be advantageous to supplement with it to boost collagen production. Two very common sources of collagen for supplements are cattle (referred to as bovine collagen), or fish (referred to as marine collagen). It’s important to understand the difference between these common sources so that you can find the best supplement for your individual needs.

Marine collagen, sourced from the skin and scales of fish, is well-suited to support the normal function of the skin and hair. Fish collagen contains a high proportion of Type I collagen fibres relative to the other types, for this reason it is referred to as a Type I collagen source. This is important because our skin is also primarily made up of Type I collagen fibres. On the other hand, bovine collagen, from cattle, may be preferred for supporting alternative tissues in the body due to its bioavailability of type II collagen fibres.

  • Type I collagen is abundant in the skin, ligaments, and tendons.
  • Type II collagen is abundant in the cartilage and joints.

Marine collagen has the most similar composition to the collagen found in human skin, so it may have superior benefits, compared to bovine collagen, for the skin and its appendages, including the hair and nails.

Sustainability benefits of marine collagen

A marine collagen supplement may be a preferable choice for sustainability reasons. Terrestrial animal farming has a much higher carbon footprint compared to aquaculture and fishing, the worst culprit being beef. Opting for marine collagen is the more sustainable choice.

Nevertheless, not all marine collagen is sustainably sourced. Marine collagen sourced through aquaculture or unsustainable fishing practices, such as trawling, is not particularly sustainable. If choosing a more sustainable, high quality marine collagen supplement is important to you, be sure to do your research.

Peptan Marine is a brand of marine collagen peptides by the global leading collagen producer Rousselot. They use 100% wild-caught fish and abide by the Marine Stewardship Council regulations. You can be sure that any brand using Peptan Marine is offering the most sustainable collagen peptides on the market.

Marine collagen peptides

Hydrolysed collagen peptides are small units of collagen protein that have been broken down through a process called hydrolysis. These peptides are smaller amino acid chains that can be more bioavailable than large proteins. As a result of their small size, peptides can pass through the lining of the digestive system and into the blood vessels. Peptides may be able to reach tissue within hours of consumption. Peptides are also dissolvable in liquids making them ideal for powdered supplements.

Marine collagen powder vs pills

Marine collagen tablets may be suitable for people with busy lives looking for convenience. Unfortunately, with convenience comes a compromise on potency; the major downside to taking tablet supplements is the low dosages of marine collagen. Also, capsule casings, fillers and binders may slow the absorption of collagen.

Powder is a popular formula for collagen supplementation; it’s odourless, colourless, and tasteless when dissolved, you can also control your own dosage. However, most importantly, powdered supplements are more easily absorbed into the body while boasting astronomically higher dosages; Beauty Complex contains well over the recommended dosage of marine collagen.

Powdered supplements can also be combined with other ingredients to support the normal function of the hair, skin and nails. It is very common to find marine collagen paired with hyaluronic acid or vitamin C.

  • Vitamin C– boosts the natural collagen synthesis in the body, contributing to the maintenance of normal collagen formation.
  • Biotin and selenium- contribute to the normal maintenance of the skin, hair and nails.
  • Vitamin E– Vitamin E contributes to the protection of cells from oxidative stress and is also involved in the normal function of the skin and hair.
  • Copper– is important for maintaining normal pigmentation in the skin and hair. While it also contributes to maintaining healthy connective tissue.
  • Phytoceramides– may contribute to improving the skin moisture barrier .

Choosing the best collagen supplement

If you wish to focus on the potential beauty benefits of collagen, choose marine collagen. Also, make sure to choose a collagen peptide product since this is thought to be the best collagen for supplementation. Peptan offers a hydrolysed marine collagen peptide product that is also sustainably sourced.

Choose a powdered supplement for superior absorbance and potency, and depending on your lifestyle, you may want to opt for marine collagen sachets for convenience.

Our delicious orange and pineapple flavoured supplement powder takes advantage of both marine collagen and collagen peptides by using a high dosage of Peptan Marine. While our powdered formula offers superior absorbance and the possibility of combining a variety of beauty agents.
