Collagen, often referred to as the “youth protein”, has become a key ingredient in nutraceutical, beauty and health formulations. Widely recognized for its benefits on skin, joints and overall well-being, collagen continues to attract growing interest from both medical experts and consumers seeking healthy aging solutions.
But what exactly is collagen, why is it so important for the human body, and how can formulators source the best collagen for innovative and sustainable products?
What Is Collagen?
Collagen is a fibrous structural protein composed of three polypeptide chains forming a strong triple helix structure. Its primary function is structural: it helps anchor cells together and provides strength, elasticity and resistance to tissues.
Collagen is the most abundant protein in the human body. It is produced by connective tissues and is naturally present in:
- Skin
- Bones
- Tendons
- Cartilage
- Joints
In the skin, collagen provides firmness and elasticity. In joints and bones, it ensures resistance to traction, flexibility and durability, making it essential for mobility and long-term skeletal health.
The Different Types of Collagen
There are several types of collagen, each playing a specific role in the body. The most well-known are:
- Type I collagen – the most abundant, representing around 90% of the body’s collagen, mainly found in skin, bones and tendons
- Type II collagen – primarily present in cartilage
- Type III collagen – associated with skin, muscles and blood vessels
This decline is caused by:
- Natural aging processes
- Lifestyle factors (diet, physical activity, stress)
- Environmental factors (pollution, UV exposure)
This is why collagen supplementation has become increasingly important in preventive health, nutricosmetics and sports nutrition.
What Are the Health Benefits of Collagen?
Collagen is known for its wide range of scientifically recognized benefits:*
Improves Skin Condition
Collagen fibers form the structural “scaffold” of the skin. Adequate collagen levels help maintain skin elasticity, firmness and hydration, while also supporting faster healing of wounds, burns and minor injuries.
Supports Heart Health
Collagen contributes to the structure of arterial walls. A deficiency may weaken blood vessels, increasing the risk of atherosclerosis, heart attack and stroke.
Strengthens Bones and Joints
Collagen protects cartilage from degradation, helps reduce inflammation and supports joint comfort. It also strengthens bones, lowers fracture risk and contributes to the prevention of osteoporosis.
Supports Muscle Mass and Recovery
Collagen accounts for approximately 10% of muscle tissue. Supplementation supports muscle structure, helps maintain tendons and ligaments, and reduces the risk of sports-related injuries.
Which Type of Collagen Is Best Absorbed?
Collagen supplements typically contain collagen peptides, obtained by hydrolyzing native collagen into smaller, more bioavailable fragments.
These peptides can originate from:
- Bovine sources
- Porcine sources
- Avian sources
- Marine sources
Thanks to their high bioavailability and compatibility with a wide range of diets, marine collagen peptides are increasingly preferred. They are easier to digest and align well with modern consumer expectations around clean-label, sustainability and transparency.
How to Source the Best Collagen for Your Formulations?
Safic-Alcan partners with COPALIS, a French company based in northern France, offering COLLAGEN HM®, a hydrolyzed and purified marine collagen extracted from the skin of wild-caught fish.
