Introduction
Collagen has become one of the most talked-about ingredients in the health and wellness industry, and for good reason. It supports the structure of skin, joints, and connective tissue throughout the body. As natural production declines with age, demand for collagen-based products keeps growing, whether the goal is personal wellness or supplement development. Understanding what collagen is and what it does is the first step.
This guide explores what collagen is, what collagen does, the different types of collagen found in the body, and the factors that can affect natural collagen production. It also covers common food sources, supplements, and practical ways to support healthy collagen levels over time.
What is Collagen?
Collagen is the most abundant protein in the human body, accounting for roughly 30% of its total protein content. Often described as the body’s structural framework, it helps provide strength, support, and organisation to tissues throughout the human body.
Like all proteins, collagen is made up of amino acids. The primary amino acids that form collagen are glycine, proline, and hydroxyproline, which combine to create collagen’s distinctive triple-helix structure. This unique structure helps give collagen its strength and durability throughout the body.
To produce collagen effectively, the body also relies on nutrients such as vitamin C, zinc, copper, and manganese.
The Function & Benefits of Collagen in the Body
Collagen works quietly but consistently across different parts of the body, supporting both appearance and function in ways you may not always notice. These include:
- Skin: Collagen helps maintain the mechanical properties, structure, and firmness of the skin. As one of the skin’s main structural proteins, it contributes to its strength and overall appearance, alongside other important factors such as elastin and hydration.
- Bones: Collagen provides the protein framework that helps support bone strength and resilience.
- Joints and cartilage: Collagen forms part of the structural matrix of cartilage and other connective tissues involved in movement, helping provide cushioning between bones and support smooth joint movement.
- Tendons and ligaments: Collagen provides tensile strength, helping these tissues withstand everyday pulling and stretching forces.
- Blood vessels and organs: Collagen contributes to the supporting structure around cells, tissues, and organs throughout the body.
- Tissue maintenance: Collagen plays a role in the normal maintenance and remodelling of connective tissues as part of the body’s natural repair processes.

The Different Types of Collagen
Scientists have identified about 28-29 types of collagen in the human body. Among them, Types I, II, III, IV, and V are the most abundant and serve many structural and supportive roles throughout the body.
1. Type I Collagen
Type I collagen is the most abundant type of collagen in the body. It is found mainly in the skin, bones, tendons, and ligaments, where it helps provide strength and structural support. In the skin, it contributes to firmness and overall skin structure, alongside other important components such as elastin.
Because of its role in supporting skin and connective tissues, Type I collagen is commonly used in beauty and healthy ageing supplements.
2. Type II Collagen
Type II collagen is found mainly in cartilage, the tissue that cushions joints and allows smooth movement. It helps support joint flexibility, mobility, and comfort.
This makes it a popular ingredient in supplements designed for active individuals and those looking to maintain long-term joint health.
3. Type III Collagen
Type III collagen is commonly found in the skin, muscles, blood vessels, and internal organs. It often occurs alongside Type I collagen, helping provide structural support and organisation to soft tissues throughout the body.
Type III collagen also plays a role in tissue repair and maintaining the structure of various organs and connective tissues.
4. Type IV Collagen
Unlike other collagen types that form fibres, Type IV collagen forms thin layers known as basement membranes. These structures act as a foundation for cells and help support the skin, blood vessels, and internal organs. Type IV collagen is important for tissue structure and the normal function of various organs throughout the body.
5. Type V Collagen
Type V collagen is present in smaller amounts but plays an essential role in the formation and organisation of collagen fibres. It is found in the skin, hair, placenta, and cornea of the eye.
What Causes Collagen Loss?
Collagen production naturally declines with age, and a range of lifestyle and environmental factors can influence this process. Understanding these factors provides useful context for why collagen remains a widely discussed ingredient in the health and wellness industry:
- Aging: Collagen production naturally declines with age. In women, collagen loss may accelerate around menopause, with some research suggesting that skin can lose up to one-third of its collagen during the early post-menopausal years.
- Sun exposure: Ultraviolet (UV) radiation can damage existing collagen and affect the body’s ability to produce new collagen. Over time, excessive sun exposure can contribute to visible signs of skin ageing, making sun protection an important part of maintaining overall skin health.
- Poor diet and nutrient deficiencies: Collagen synthesis depends on specific nutrients, including vitamin C, zinc, and copper, along with adequate protein intake. A diet lacking these building blocks can limit the body’s ability to produce collagen efficiently, regardless of age.
- Smoking: Smoking reduces blood flow to the skin and introduces toxins that damage collagen and elastin fibers.
- Chronic stress: Elevated cortisol levels associated with chronic stress can interfere with collagen production and accelerate its breakdown over time.
How to Support Healthy Collagen Levels
Collagen levels can be supported through a combination of:
- collagen-rich foods
- collagen-supporting nutrients
- dietary supplements
For brands looking to develop collagen products, understanding these different approaches can help inform formulation strategies and provide a better understanding of how collagen is used across the health and wellness market.
What Foods Contain Collagen & Support Collagen Production?
• Bone Broth
A classic source of collagen made by slow-cooking bones and connective tissues, releasing nutrients that support the body from within. It is also commonly valued for its warming and nourishing effect, making it easy to include in daily meals.
• Fish with Skin
A rich source of marine collagen that is easier for the body to absorb, making it especially beneficial for skin support. Regular consumption may help support skin elasticity and overall hydration over time.
• Chicken
Contains collagen in its skin and connective tissues, which are often overlooked but highly valuable for daily intake. Including these parts in your meals can naturally increase your collagen intake without major diet changes.
• Egg Whites
Does not contain collagen directly, but are rich in amino acids that help your body produce collagen naturally. They also provide a clean and versatile protein source that fits easily into different types of meals.
• Fruits and Vegetables
Oranges, berries, and leafy greens provide vitamin C and antioxidants that support collagen production and maintenance. These nutrients help protect existing collagen while supporting your body’s ability to build new collagen.
What Kinds of Collagen Supplements Are There?
Collagen supplements are available in a wide range of formats and product categories, allowing brands to target different consumer needs and market segments:
- General wellness supplements: Commonly available as powders, capsules, tablets, gummies, and ready-to-drink beverages, these products typically contain hydrolysed collagen peptides either on their own or alongside complementary ingredients.
- Beauty supplements: Often marketed as beauty-from-within products, these formulations commonly combine collagen with ingredients associated with skin, hair, and nail wellness.
- Sports nutrition supplements: Collagen is also used in sports nutrition products, particularly those designed for active individuals. These formulations are commonly available as powders and beverages, either as standalone collagen products or blended with other nutritional ingredients.
- Functional food products: Some brands incorporate collagen into protein bars, snacks, beverages, and other functional food products, offering consumers alternative ways to incorporate collagen into their daily routines.
How are Collagen Supplements Made?
Collagen supplements are produced through a series of processing steps that convert animal- or marine-derived materials into collagen peptides suitable for use in supplement formulations. The process typically involves the following stages:
1. Sourcing and Preparation
Collagen can be sourced from bovine, marine, or poultry-derived materials. Before processing begins, the raw materials are cleaned and prepared to remove impurities such as fats, minerals, and other unwanted components.
2. Extraction
The prepared materials undergo an extraction process to release collagen from the surrounding tissues. Different manufacturers may use acid, enzymatic, thermal, or other processing methods depending on the source material and desired outcome.
3. Hydrolysis
To create collagen peptides, the extracted collagen is broken down into smaller protein fragments using enzymes. This process, known as hydrolysis, produces collagen peptides that dissolve more easily and are commonly used in supplement formulations.
4. Purification and Concentration
The collagen solution is then purified to remove any remaining impurities and improve consistency. It may also be concentrated before moving to the next stage of production.
5. Drying and Formulation
The purified collagen is typically dried into a powder, often using spray-drying technology. From there, it can be packaged as a standalone collagen powder or formulated into various supplement formats.
6. Quality Testing
Before reaching the market, collagen ingredients and finished products usually undergo quality testing to assess factors such as protein content, purity, safety, and product consistency. Depending on the target market, manufacturers may also obtain certifications such as halal certification and conduct additional testing to meet regulatory requirements.
Tips for Brands Looking to Develop Collagen Supplements
1. Choose your collagen source carefully
Your target market should guide this decision. Marine collagen often appeals to consumers looking for fish-based alternatives and is commonly positioned as a premium option, while bovine collagen remains a popular and cost-effective choice.
If you plan to obtain halal certification, confirm early that your collagen source and manufacturing facility can meet the requirements.
2. Understand peptide molecular weight
Not all hydrolyzed collagen is the same. Lower molecular weight peptides are generally associated with better absorption, which can be a meaningful differentiator in your marketing and formulation. Ask your supplier for data on peptide size distribution rather than relying on marketing claims alone.
3. Prioritize a manufacturer with transparent sourcing
Consumers increasingly want to know where their supplements come from. Partnering with a manufacturer that can document sourcing, from raw material origin to finished product, gives you a stronger story to tell and helps protect your brand from supply chain issues.
4. Test for taste and solubility early
Collagen peptides can have a mild taste or odor depending on the source and processing method. If you are developing a beverage or gummy, test formulations early to make sure the final product is palatable, since taste issues are one of the most common reasons consumer products underperform.
5. Don’t overlook regulatory requirements
In Malaysia, collagen supplements must comply with regulatory requirements relating to ingredients, labelling, product registration, and permitted health claims. Understanding these requirements early can help brands bring compliant products to market more efficiently.
6. Consider combining collagen with complementary ingredients
Many collagen products include ingredients such as vitamin C, hyaluronic acid, or biotin to create a more well-rounded formulation and appeal to different consumer needs. Discuss your formulation goals with your manufacturer early, as some ingredient combinations may require additional testing or adjustments during product development.
