What Are The Differences Between Marine Collagen And Bovine Collagen?
For some years there has been a controversy over which type of collagen is better, whether marine or bovine. What does the evidence say about it? What is the difference between them? Here we detail it.
In recent years, the marketing of collagen-based food supplements has raised doubts about which variety is better, whether it is of marine or bovine origin. However, there are several controversies and investigations in this regard. Do you know their main differences?
Collagen is the most abundant protein in the human body. In addition, it is present in a wide variety of animals. According to a review published in the Journal of Cosmetic Dermatology , it is one of the main components of the skin, bones, joints, and blood vessels.
Today it is a widespread protein as a dietary supplement, as it is associated with health benefits. It is even popular within the cosmetic industry, as it appears to delay the onset of aging. But, which variety of collagen is most recommended?
Marine collagen versus bovine collagen
Several collagen-based supplements are available on the market, among which the marine origin and the one from bovines stand out. Both are attributed a series of properties, such as that they can contribute to the health of the skin or joints. And while there are studies to back this up, a debate has sparked over which variety is better.
It is common to see advertisements that claim that collagen of marine origin “is more assimilable than terrestrial.” In turn, it is suggested that it is a presentation with almost miraculous health effects. However, it is important to know that all collagens are similar and, when assimilated, the body does not differentiate their origin.
In other words, the biological value, assimilation and properties of marine collagen are not superior or worse than those obtained from cattle. What matters in both cases is its degree of hydrolysis, which is what allows its absorption into the body.
The hydrolyzation process is also known as “fragmentation” or “predigestion” and consists of the elimination of fat and unwanted materials to obtain only amino acids (which is what the body uses). Regardless of its source, only collagen that has been sufficiently hydrolyzed manages to reach the tissues that use it as a nutrient.
