Collagen vs Elastin

The difference between collagen and elastin is that the main function of collagen is to strengthen the muscles, whereas the main function of elastin is to provide elasticity to the muscles. The collagen protein is secreted by the body throughout the lifetime of a human. It is produced abundantly when a muscle is injured to return the muscle strength.

Collagen vs Elastin

Collagen is the protein secreted by our body to strengthen the muscles. It is abundantly formed when our muscles get injured or tear up due to intense workouts.

Elastin is the protein produced by our body to provide elasticity to the muscles. This protein is abundantly produced during the fetus stage of an organism.

What is Collagen?

Collagen is the protein secreted by our body to strengthen the muscles. It is abundantly formed when our muscles get injured or tear up due to intense workouts.

It is the main protein that is found in ligaments, bones, tendons, etc. it helps to join bone to bone and other parts together. It is very strong and less flexible.

Vitamin A, vitamin C, and copper are very important for the production of collagen in the body. Collagen is produced in the body throughout the life cycle of a human being.

So we need to follow a balanced diet and do regular exercises to maintain the balance of the nutrients. Intence workouts lead to breakage and tear in the muscles.

What is Elastin?

Elastin is the protein produced by our body to provide elasticity to the muscles. This protein is abundantly produced during the fetus stage of an organism.

Elastin is less abundant in our body as compared t collagen. But it is found in excessive amounts in the fetus stage, as at that time of development of a body and elasticity is very needed for the formation of cells.

For example, the increase in height, stronger muscle development in males, etc., all these need a huge amount of elastin.

Decreased amount of elastin leads to wrinkles and a leathery look to the skin. It is mainly found in blood vessels and skin. The amount of elastin reduces as we grow old.

Main Differences Between Collagen and Elastin

  1. The protein called collagen is produced throughout the lifetime of humans. On the other hand, a protein called elastin is abundantly produced during the fetus period and stops after puberty.
  2. Collagen provides strength to the muscles, whereas elastin provides elasticity to the muscles.
