Understanding Types 1 and 3 Collagen

Written by Magnus Sørensen | May 29, 2024 10:15:38 AM

Collagen is the most abundant protein in the human body, playing a critical role in maintaining the structural integrity of various tissues. With its unique fibrous structure, collagen provides strength and elasticity to the skin, tendons, ligaments, and bones. Among the many types of collagen, Types 1 and 3 are particularly significant due to their prevalent roles in the human body. This article will delve into the intricacies of these two types of collagen, their functions, benefits, and how they can be effectively supplemented through products offered by Swedish Nutra, a leading provider of high-quality collagen supplements.

What is Collagen?

Collagen is a protein composed of amino acids, primarily glycine, proline, and hydroxyproline. It forms a triple-helix structure that is both strong and flexible, making it essential for maintaining the structural integrity of various tissues. Collagen can be found in the skin, bones, cartilage, and connective tissues, and it is crucial for tissue repair and regeneration.



Types of Collagen

There are at least 28 different types of collagen, but Types 1 and 3 are the most abundant in the human body. Each type has a unique structure and function, contributing to the body's health and well-being.

The main sources of collagen include marine collagen, sourced from fish (particularly fish skin and scales). Marine collagen has high bioavailability, absorbs more efficiently, and is rich in Type I collagen. It is commonly used in supplements and cosmetics. Bovine collagen, meanwhile, comes from cow hides and bones. It is rich in Types I and III collagen, is widely available, and is effective for skin, joint, and bone health. It is commonly used in supplements, bone broth, and gelatin products.

Porcine collagen is sourced from pig skin and bones, similar to human collagen. It is rich in Type I collagen and good for skin and joint health. It is used in supplements and cosmetics. Chicken collagen is sourced from chicken cartilage and sternum. It is rich in Type II collagen and beneficial for joint health and cartilage repair. It is commonly used in supplements, especially for joint health.

Vegan collagen is a relatively new innovation and is not directly sourced from plants since plants do not produce collagen. Instead, vegan collagen is made through genetically modified yeast and bacteria like Pichia pastoris. Scientists introduce human genes into the microbes, causing them to produce collagen. This lab-created collagen is then used in various supplements and cosmetics. Vegan collagen provides an animal-free alternative for those adhering to a vegan lifestyle or looking to avoid animal products for ethical or health reasons. Additionally, vegan collagen often includes ingredients that support the body’s natural collagen production, such as vitamins C and E, zinc, and biotin.

Type 1 Collagen

Type 1 collagen is the most prevalent form of collagen in the human body, accounting for approximately 90% of the body’s collagen supply. It is predominantly found in:

  • Skin: Provides structure and elasticity.
  • Tendons and Ligaments: Offers tensile strength.
  • Bones: Contributes to bone strength and density.
  • Cornea: Maintains eye structure.
Functions and Benefits of Type 1 Collagen
  1. Skin Health: Type 1 collagen is crucial for skin elasticity and hydration. It helps reduce wrinkles and fine lines, promoting a youthful appearance.
  2. Bone Strength: It supports bone density and strength, reducing the risk of fractures and osteoporosis.
  3. Wound Healing: Type 1 collagen aids in tissue repair and regeneration, accelerating wound healing.
  4. Joint Health: It provides the necessary strength and structure to tendons and ligaments, supporting joint health and mobility.


Type 3 Collagen

Type 3 collagen is the second most abundant collagen in the human body. It is often found alongside Type 1 collagen and is prevalent in:

  • Skin: Contributes to skin structure and elasticity.
  • Blood Vessels: Provides structural support to blood vessels.
  • Internal Organs: Maintains the structural integrity of organs such as the liver, spleen, and lungs.
Functions and Benefits of Type 3 Collagen
  1. Skin Elasticity: Type 3 collagen enhances skin elasticity, helping to maintain a firm and smooth complexion.
  2. Cardiovascular Health: It supports the structure of blood vessels, promoting cardiovascular health.
  3. Organ Health: Type 3 collagen ensures the proper functioning of internal organs by maintaining their structural integrity.
  4. Tissue Repair: Similar to Type 1, Type 3 collagen plays a role in wound healing and tissue regeneration.

The Synergy Between Types 1 and 3 Collagen

Type 1 and Type 3 collagen often work synergistically to provide comprehensive bodily benefits. Their combined presence is crucial for maintaining skin health, promoting wound healing, and supporting the structural integrity of various tissues. Supplementing with both types can enhance overall health and well-being, making choosing products that blend these collagens essential.
