In recent years, collagen has become a buzzword in the worlds of beauty and wellness. Whether you're browsing the skincare aisle at a drugstore, watching TV commercials, or chatting with friends, chances are you've come across the term "collagen." But do you really know what collagen is? With an overwhelming variety of collagen products on the market—ranging from powders and drinks to capsules and tablets—how do you choose the right one to truly enhance your beauty and health?

This article will walk you through exactly what collagen is and introduce four common forms of collagen supplements—making it easier for you to boost your youthful glow from the inside out!

What Is Collagen? Collagen is a type of fibrous protein that accounts for approximately 25% to 30% of the total protein content in the human body. It is widely distributed throughout various tissues, including the skin, bones, tendons, ligaments, cartilage, blood vessel walls, and internal organs. Characterized by its unique triple-helix structure, collagen is primarily composed of three amino acids: glycine, proline, and hydroxyproline. This structure gives collagen its exceptional tensile strength and elasticity, enabling it to maintain the structural integrity of tissues. In essence, collagen functions like the “steel rebar” within the body—providing crucial support and stability to our biological framework.

According to scientific literature, more than 29 types of collagen have been identified to date. Among these, the types most relevant to daily health and wellness are Type I, Type II, and Type III collagen:

• Type I Collagen: This is the most abundant form of collagen in the human body, accounting for approximately 90% of all collagen. In the dermis, Type I collagen forms a dense, interwoven fibrous network that supports skin cells and blood vessels, helping to maintain the skin’s structure, firmness, and elasticity. Beyond the skin, Type I collagen is also found in tendons, ligaments, cartilage, and blood vessels, serving as a critical structural component in various connective tissues throughout the body.

• Type II Collagen: This type has a more loosely organized structure and is primarily found in joint-related areas. It plays a key role in maintaining flexibility and mobility, making it an essential nutrient for joint health—especially important for middle-aged and older adults as part of their daily wellness routine.

• Type III Collagen: Type III collagen often coexists with Type I collagen and is primarily distributed in the deeper layers of the skin and internal structures. It helps maintain tissue elasticity and stability, and it is recommended to be supplemented together with Type I collagen for optimal benefits.

Collagen is the most abundant protein in the human body. In daily life, it can be obtained from animal-based foods such as pork skin, beef tendons, fish skin, and chicken feet. It can also be supplemented through dietary or nutritional supplements for added convenience and targeted support.

However, research shows that collagen levels naturally decline with age. Collagen production typically peaks between the ages of 25 and 34, after which it gradually decreases—by about 25% over the following 40 years, averaging a loss of approximately 0.6% per year. In addition to natural aging, several lifestyle factors can accelerate collagen degradation. These include prolonged exposure to UV radiation, highly processed diets, irregular sleep patterns, and chronic stress. As a result, individuals may experience reduced skin elasticity, joint stiffness, and a slower overall recovery and repair capacity in the body.

Therefore, collagen is not only a key ingredient for maintaining healthy, youthful skin—it also plays a vital role in supporting the proper function and flexibility of various systems throughout the body. Below is an overview of collagen’s multiple health benefits, helping you better understand why it’s such an essential component of overall wellness:

• Beauty and Skincare:

Collagen is an essential component of the skin, helping to maintain its elasticity and structural integrity. Proper supplementation can support youthful and radiant skin, making it a top choice for many beauty enthusiasts!

•  Support for Daily Mobility:

As we age, physical movement may gradually become more challenging. Proper collagen supplementation can help maintain flexibility, making everyday activities easier and more comfortable.

•  Health Maintenance:

Dry or split hair, brittle nails, or ridged nail surfaces may be related to daily nutritional intake. Collagen is one of the key components of skin and connective tissues. Proper supplementation can help regulate bodily functions and support overall health maintenance.

•  Boost Metabolism:

Collagen contains a variety of amino acids that serve as essential building blocks for the body’s structural integrity. For those who exercise regularly and prioritize physical strength and vitality, proper collagen intake helps provide essential daily nutrients and supports healthy metabolic function.

After gaining a clear understanding of what collagen is and the benefits it offers, the next step is selecting the most suitable supplementation method. With a wide variety of formulations available on the market, choosing the right one may seem overwhelming. To assist you in making an informed decision, we have compiled an overview of the four most common collagen supplement formats along with their key characteristics. We recommend selecting a format that aligns with your daily routine and personal preferences, allowing you to incorporate collagen supplementation into your lifestyle with ease and consistency.

1. Powder

Powdered Collagen is typically available in small molecule forms, which are known for their high absorption efficiency. There are two common types on the market: one that can be consumed directly, and another that needs to be mixed with water or beverages. This format is ideal for individuals who prefer not to swallow capsules or tablets. However, collagen powder is prone to moisture and clumping. To maintain product quality and stability, it is recommended to choose options with well-sealed, individual packaging for better freshness and convenience.

In addition, it's important to pay close attention to the fineness of the powder when purchasing. Products of lower quality may produce excess dust, which can lead to issues such as inhalation, throat irritation, or sticking to the teeth. To enhance the overall consumption experience, it is advisable to choose collagen powders that have been processed using advanced granulation technology—these products typically offer a smoother texture, are easier to consume, and provide a more pleasant mouthfeel.

2. Drinkable Collagen

Liquid collagen is known for its quick absorption and ease of consumption, making it a convenient choice for many. This format can also carry a higher concentration of collagen along with other active ingredients, such as vitamin C and hyaluronic acid, which can enhance both the effectiveness and palatability of the supplement. However, to improve taste, some products may contain flavorings or sweeteners. When selecting a liquid collagen product, it is recommended to prioritize formulations with minimal additives to ensure a purer and more health-conscious choice.

3. Capsule Form

Collagen in capsule form is encased in a gelatin shell that helps isolate it from air, enhancing stability and shelf life. It's convenient to carry and effectively masks the fishy smell or unpleasant taste often associated with collagen supplements. However, it’s important to note that each capsule can only contain a limited amount of collagen. To reach the recommended daily intake, multiple capsules may need to be taken at once, which could be inconvenient for some individuals.

4. Tablet Form

Collagen tablets offer pre-measured doses and are easy to carry, making them a convenient, ready-to-swallow option without the need for mixing or preparation. However, during the manufacturing process, excipients and binders are often added to help form the tablet, which may result in lower ingredient purity compared to other forms. Additionally, tablets tend to have a slower absorption rate, and like capsules, their dosage capacity is limited. When choosing a tablet-type collagen supplement, it’s advisable to look for products made with smaller collagen molecules to enhance bioavailability and absorption efficiency.

In addition to the four common collagen supplement formats mentioned above, some brands are now combining the advantages of multiple delivery forms to create innovative “dual-format” solutions. Take DR.WU’s Beauty Shot series as an example. This line features a dual-collagen peptide drink paired with function-specific beauty tablets, offering targeted solutions for various skin concerns. The series includes three formulations: 「Hydrating」 、「Brightenin」 、 「Night Calm」. This flexible approach allows users to tailor their skincare routine based on their skin’s current needs. With this kind of integrated supplement system, daily beauty maintenance becomes more convenient and effective, helping you achieve visibly radiant skin—one sip at a time.

Developed by a team of professional doctors, DR.WU offers two options: the Dual Collagen Peptide Powder and the Dual Collagen Peptide Drink.
