Marine Collagen vs. Bovine Collagen: Differences and Benefits Explained
Marine Collagen or Bovine Collagen? Collagen is the most abundant protein in the human body. Unfortunately, however, starting at the age of 30, we lose approximately 1% of our body’s natural collagen production, which leads to a loss of natural skin elasticity, slower recovery from wrinkles, and can also affect gut health. Over time, this natural loss of collagen can also impact muscle recovery, joints, and even gastrointestinal health.
Studies have shown that supplementing your diet with ingestible collagen can help transport it to where it's needed in the body quickly and may play a role in preventing the effects of natural collagen loss. However, how do we choose the right collagen for us? Here are the differences between marine collagen and bovine collagen.
Marine collagen vs. Bovine collagen
1. Source
The main difference between marine and bovine collagen is the source from which they are obtained. Marine collagen usually comes from wild-caught fish, which ensures an ethical and sustainable extraction process. It is obtained from the skin and scales of fish through a hydrolysis process, which breaks down the collagen molecules into smaller peptides that are easily absorbed by the body. Bovine collagen, on the other hand, is derived from the hides of ethically raised cows, often on pasture. This means that the source of bovine collagen depends on the farming of the animals and can vary depending on their diet and growing conditions.
2. Types of Collagen
In terms of collagen types, marine collagen is predominantly rich in Type I collagen , which is essential for healthy skin, bones and connective tissue. It also contains Type II collagen, which supports joint health. In contrast, bovine collagen contains both Type I and Type III, providing additional benefits for tissues that require elasticity, such as muscles and blood vessels. Thus, each type of collagen has its own unique properties, which suit different health and beauty needs. 21Collagen is hydrolyzed marine collagen and is particularly rich in Type I collagen, the most widespread in the human body (being present in skin, bones, tendons and other connective tissues). However, it also contains small amounts of Type III collagen. 
3. Bioavailability
Should I take both?
Yes, it would be beneficial to take both types of collagen, both marine collagen and bovine collagen. Each of these offers unique benefits due to the different types of collagen they contain. By combining the two, you ensure that you are getting a broader spectrum of essential nutrients, thereby supporting the health of your skin, joints, muscles, and bones. This holistic approach can contribute to better overall health and faster recovery.
