The Ultimate Marine Collagen Peptides Guide

Collagen is the most abundant protein in our bodies, found in the skin, muscles, tendons, and ligaments. As we’ll see, it plays numerous key roles in promoting longevity and good health. However, as the body ages, not only does it produce less collagen, but existing collagen breaks down as well, which is why people turn to supplementing their diet with different types of collagen.

Collagen Sources

Collagen for use as a diet supplement is generally extracted from the following animals:

  • Fish - Marine collagen
  • Cows - Bovine collagen
  • Pigs - Porcine collagen

There are no plant-based collagen sources.

If you are following a particular eating plan, you will be pleased to know that Marine Collagen is suitable for followers of the keto diet. It is also paleo and pescetarian-friendly.

In this article, we’ll specifically take a deeper look into Marine Collagen and the benefits it offers.

What Is Marine Collagen?

Marine Collagen is a pure, hypoallergenic form of collagen peptides made from fish skins left over after food production, making it a source of Collagen that doesn’t put additional stress on ecosystems.

Although all collagen is composed of the same amino acids, marine collagen contains higher amounts of amino acids Proline and Glycine, compared to Porcine or Bovine-derived collagen.

Including Marine Collagen supplements as part of your diet may improve your lifestyle in a variety of ways. Potential benefits of Marine Collagen include the following.

Possible Reduction in Inflammation and Joint Pain

Our bones are cushioned by collagen's smooth, gel-like structure. For individuals with swollen, painful, or inflamed joints, collagen supplements may be beneficial.

Healthier Bones

Calcium gets all the credit for healthy bones, but collagen deserves some attention too. It helps keep our bones strong by supporting their structure as we age.

It May Boost Metabolism

Collagen supplements may also play a role in supporting metabolism by increasing the amount of lean muscle mass in the body.

A study found that individuals who supplemented with collagen peptides and participated in resistance training improved their body composition compared to a group who did not include collagen supplementation.

Marine collagen also helps increase satiety to help individuals feel full for longer -- an excellent tool if you are trying to lose weight. Early animal research suggests it may even help promote healthy blood sugar levels.

Healthy Arteries

Our arterial walls are made up of collagen. Taking collagen supplements may help our arteries carry nutrients and oxygen throughout the body, particularly the brain.

It has been shown in many studies that collagen may reduce the growth of disease and infection-causing bacteria.

Hi Steve,

Thanks for the question.

Our Marine Collagen Powder consists primarily of collagen type I and a small amount of collagen type III. The percentage of type I and type III collagen may vary for each batch so the exact ratio has not been determined. What is certain is that it is predominantly Type I with trace amounts of Type III.

The type III collagen present in our marine collagen is not supplemented. These trace amounts of type III collagen are detected when we conduct our routine test for the product. No artificial ingredients or additives were used in the production of our marine collagen powder.

Your marine collagen boasts Type 1 & Type 3 collagens. All of the sites that I have visited say that marine collagen is high in type 1 but does not contain type 3. Are you supplementing the type 3? Is there a way for the consumer to see just how much of each type of collagen is present per scoop?

Hi Viktor,

The Marine Collagen powder should be good until the expiration date specified on the container. But you have to ensure that the product is properly stored.

To properly store an opened container of Marine Collagen Powder, make sure that the container is closed tightly. Make sure that you store it away from heat and moisture, freezing and excessive light. Placing it in a refrigerator can attract moisture so it is best to store it at room temperature, in a dry place.

I hope this helps.

Hi Bud F-F,

Thanks for the question.

Marine Collagen is unflavored and neutral, so you should be able to mix it into any liquid with little change to the original drink.

That said, everyone has a different palate, and some people may be more sensitive to the taste/smell. In those cases, we would recommend mixing it with a strong-flavored drink like coffee, or if mixing with tea or water, to add a squeeze of fresh lemon juice.

Hope this helps.
