Collagen protein is like a screw in a machine. If just one is gone, nothing bad happens. But, when more are missing, the machine stops working.

The same is true for your body. When there aren't enough collagen proteins, you start to have problems with your joints, skin, hair or nails.

The same goes for your body.

This is why it is important to take care of the correct concentration of collagen proteins in the body. Together with Ilona Krzak, MSc, pharmacist, we will present the most important information about them.

  • What collagen proteins are and where they are found.
  • .
  • How collagen proteins work and what are the symptoms of collagen deficiency.

What is collagen protein?

.

Collagen protein (commonly known as collagen) is a structural protein that makes up 25-35% of all protein in your body. It plays a key role in the connective tissue system, affecting its strength and integrity. Among other things, it influences skin condition, wound healing and cell functionand.

Where does collagen protein occur?

.

Collagen protein is found in many structures in the body. The most important of these areand:

  • skin - collagen protein is the basic structure of the skin, giving it elasticity, firmness and resistance to mechanical damage.
  • Bones - collagen protein works together with minerals such as calcium. This maintains the strength and susceptibility of bones to fracture.
  • Blood vessel walls - the presence of collagen protein in blood vessel walls helps them to remain flexible and strong.
  • Cartilage - collagen protein is the main structural component of cartilage.
  • .
  • Fascia and tendons - this is the primary component of ligaments and tendons, responsible for connecting bones and stabilising joints.

Collagen protein production decreases as the body ages. This leads to the first symptoms of collagen deficiency, such as loss of skin elasticity or skeletal problemsand.

.
The main organic component of bone and dentin is type I collagen.

Collagen - simple or complex protein?

.

Collagen is a complex protein that consists of three polypeptide chains twisted together by a triple helix. Each chain contains approximately 1,000 amino acids. These amino acids are distinguished by an unusual peptide sequence, which is repeated every third amino acidand.

How does collagen protein work?

.

Collagen protein is involved in the formation of collagen fibres, which are essential for the body to function. The most important tasks of collagen protein areand:

      .
    • Structure formation. Collagen protein makes up the collagen fibres, which provide the basic scaffolding for many tissues, including skin, bone, cartilage, tendons and ligaments.
    • Collagen proteins are used for the formation of collagen fibres, which are the basic scaffolding for many tissues, including skin, bone, cartilage, tendons and ligaments.
    • Giving flexibility. Collagen fibres form an elastic mesh that allows tissues to stretch and return to their original structure when relieved.

 

  • Tissue strengthening. Collagen protein forms reinforcing layers for various tissues, protecting them from mechanical damage.
  • Wound healing. Collagen speeds up the wound healing process by creating a scaffold on which cells can grow to rebuild damaged tissues.
  • Cellular interactions. Collagen protein enhances intercellular communication, enabling a variety of biological processes such as tissue growth, cell migration and tissue repair.
  • Tissue hydration. Collagen protein controls the level of hydration in tissues, especially in the skin, maintaining its healthy appearance.

 

What are the symptoms of collagen protein deficiency?

.

Deficiency of collagen proteins (collagen) leads to various health problems. You start to lack them as early as 25-30 years of age, so a healthy diet and sensible supplementation is important.

Symptoms of collagen protein deficiencyand

    • Deficiencies in connective tissues. Collagen supports the elasticity and strength of connective tissue. If it is lacking in the body, tissues can weaken and lose their elastic properties.
    • Weakened joints and muscles. Collagen supports joints, ligaments and muscles. Its deficiency can lead to joint discomfort and greater susceptibility to injury.
    • .
    • Problems with skin, hair and nails. Collagen proteins affect the appearance and structure of skin, hair and nails. A lack of these can result in dry and flabby skin, brittle hair and weakened nails.
    • Collagen proteins can also affect the appearance and structure of skin, hair and nails.
    • Osteoporosis. Collagen is an important part of bone structure. A collagen deficiency can increase the risk of osteoporosis, a condition that leads to reduced bone density and increases the risk of fractures.

 

  • Wound healing disorders. Collagen proteins play an important role in the wound healing process. Their absence can lead to delayed healing and increased susceptibility to infection.

 

In order to ensure adequate collagen in the body, a healthy, balanced diet rich in protein, vitamin C and other nutrients to support collagen protein production should be taken care of. In some cases, collagen supplementation may also be indicated.

What is the difference between bovine collagen protein and fish protein?

.

There are two common types of collagen protein on the market - fish origin (English: marine collagen) and beef collagen. Occasionally you may also come across porcine collagen protein. However, its properties are strongly similar to beefand.

Research suggests that fish-derived collagen protein is absorbed (assimilated) up to 50% better than beef protein. Therefore, it will usually be the better choice. The exception to this is if you are allergic to marine products, in which case beef or pork collagen proteinand is the better choice. (But also vice versa).

.

.

Note

Beef and pork collagen protein is not harmful. Nevertheless, there is a risk of contracting an animal-borne disease. Therefore, pay attention to the quality of the collagen supplements you choose.

.

Is hydrolysed collagen protein the best solution?

.

Yes, hydrolysed collagen protein is the best type of supplement you can choose. It absorbs much better than natural collagen and can realistically support your body. Studies suggest that regular intake of 2.5-15 grams of hydrolysed collagen protein supports the health of hair, skin, nails and jointsand.

What are the contraindications to the use of collagen protein?

.

Most often, collagen protein does not cause adverse reactions. However, some people should be particularly cautious before starting supplementation.

Collagen contraindicationsand:

    .
  • allergies to the ingredients in the preparation,
  • .
  • kidney and liver diseases,
  • .
  • adherence to selected medications,
  • .
  • pregnancy and breastfeeding period,
  • .
  • gastrointestinal problems,
  • .
  • autoimmune disorders,
  • .

Is collagen protein harmful?

.

No, collagen protein is not harmful. What's more, it is crucial to the body's health. However, sometimes side effects can occur during collagen protein supplementation. In most cases, they are mild and include allergic reactions or stomach problemsand.
