What is Collagen and Why is it so Important?

Collagen is a protein that makes up a significant portion of our body's connective tissues, including our skin, hair, and nails. It is one of the most abundant proteins in the human body, accounting for about 30% of the total protein content. Collagen is often called the body's "glue" because it helps hold everything together, providing strength and structure to various tissues.

There are at least 16 types of collagen, but types I, II, and III are the most common and play a crucial role in maintaining skin, hair, and nail health:

  • Type I: This type is the most abundant and provides structure to the skin, provides bone mineral density, tendons, and other connective tissues.
  • Type II: Primarily found in cartilage, type II collagen is essential for joint health (helps reduce joint pain) and flexibility.
  • Type III: This type supports the structure of muscles, organs, and arteries and is often found alongside type I collagen.

Dr. Aivaz, a renowned dermatologist, explains, "From our mid-20s onward, we gradually start to lose collagen. For women, this can reach 30% of their total collagen production in the initial five years of menopause!"

Type Description Common Sources Benefits
Type I This is the most abundant type of collagen in the human body, accounting for about 90% of the body's total collagen. Type I collagen provides structure to skin, tendons, ligaments, and bones. It is also found in the cornea and scar tissue. Bovine, fish, and marine collagen Supports skin health, hair health, and nail strength; improves skin elasticity and hydration; reduces wrinkles and fine lines; promotes the health of tendons and ligaments
Type II Type II collagen is primarily found in cartilage, which is the flexible connective tissue that cushions joints. It is also present in the vitreous humor of the eye. Type II collagen helps to maintain the structure and strength of cartilage. Chicken and bovine cartilage Supports joint health; promotes cartilage regeneration; reduces joint pain and inflammation; may help with conditions like osteoarthritis
Type III Type III collagen is found in skin, muscles, blood vessels, and the walls of various organs. It plays a vital role in maintaining the structure and elasticity of these tissues, making it important for overall skin health and the health of blood vessels. Bovine and fish collagen Supports skin health; promotes elasticity and hydration; strengthens blood vessels; maintains the structure of various organs
Type IV Type IV collagen is found primarily in the basement membranes, which are thin layers of tissue that separate the skin's layers and other tissue types. It plays a crucial role in maintaining the structural integrity of these membranes and providing support to surrounding tissues. Eggshell membrane collagen Supports skin health; maintains the structural integrity of basement membranes; provides support to surrounding tissues
Type V Type V collagen is found in cell surfaces, hair, and the placenta. It plays a role in the formation of fibrillar collagens (like types I, II, and III) and the regulation of collagen fiber assembly. Type V collagen is essential for the proper formation of connective tissues and is particularly important during the development of the placenta during pregnancy. Bovine and fish collagen Supports hair health; regulates collagen fiber assembly; essential for proper formation of connective tissues; plays a role in placenta development during pregnancy
Type X Type X collagen is found in small amounts in various tissues, including cartilage and bone. It plays a role in the formation of new cartilage and the calcification of cartilage to form bone. Type X collagen is believed to be important for maintaining the health of articular cartilage, which is the cartilage that lines the surfaces of joints and helps to reduce friction and cushion the joint. Chicken and bovine cartilage Supports cartilage and bone health; promotes the formation of new cartilage; maintains the health of articular cartilage

Please note that there are more than 28 types of collagen in the human body, but the ones mentioned above are the most common and well-researched. While this table provides a general overview of the different types of collagen and their benefits, it is important to consult with a healthcare professional before starting any new supplement regimen.

Collagen production can also be influenced by factors such as sun exposure, smoking, and a poor diet. By maintaining a healthy lifestyle and supplementing with collagen, you may be able to support your body's collagen levels and improve the appearance of your skin, hair, and nails.

The Science Behind Collagen Supplements

Several studies have investigated the efficacy of collagen supplements in promoting skin, hair, and nail health. Here's a closer look at some of the key research findings:

Skin Health

A 2019 review of eight clinical trials published in the Journal of Drugs in Dermatology found that taking collagen supplements led to improvements in skin elasticity, skin hydration, and overall appearance. Participants who took collagen supplements for 8-24 weeks experienced a significant increase in elasticity and skin hydration compared to those who took a placebo. 

Additionally, some studies reported a reduction in the appearance of wrinkles and fine lines.

Another double-blind, placebo-controlled study published in Skin Pharmacology and Physiology followed 69 women aged 35-55 for eight weeks. 

The women who took collagen peptides showed significantly improved skin elasticity compared to the placebo group. The researchers concluded collagen supplementation could improve skin elasticity, especially in older populations.

Hair Health

While there are fewer studies on the effects of collagen supplements on hair health, some research suggests that these supplements may help promote hair growth and thickness. 

study published in the Journal of Cosmetic Dermatology reported that participants who took collagen supplements for 12 weeks experienced increased hair thickness and a reduction in hair loss.

Collagen may promote hair health by providing essential amino acids, such as proline, a major component of keratin, the protein that makes up our hair. Additionally, collagen has antioxidant properties that can combat free radicals, which can damage hair follicles and contribute to hair loss.

Nail Health

Collagen supplements have also been studied for their potential to strengthen nails. A 2017 study published in the Journal of Cosmetic Dermatology found that participants who took a collagen supplement for 24 weeks experienced a 12% increase in nail growth and a 42% decrease in the frequency of broken nails. The participants also reported improvements in the overall appearance and health of their nails.

While these findings are promising, it's wise to note that more research and case studies are needed to fully understand the health benefits of collagen supplementation. Before starting any new supplement regimen, consult a healthcare professional to ensure it's safe and appropriate for your needs.

Types of Collagen Supplements

When selecting a collagen supplement, you have options; pills, collagen powder, and liquids are all available. Finding the one that works best for your needs requires evaluating each type's advantages and disadvantages to make an informed decision.


Pills, or oral collagen supplements, are a popular and convenient form of collagen supplement. They're easy to take and often combined with other beneficial ingredients like vitamins and minerals to support overall health. However, pills may be harder for some people to swallow, and they typically have a slower absorption rate than other forms of collagen supplements.


  • Easy to take
  • Often combined with other beneficial ingredients
  • Portable and convenient for on-the-go use


  • May be difficult for some people to swallow
  • Slower absorption rate compared to other forms


Collagen powders are versatile and can be easily incorporated into your daily routine. They can be mixed into various beverages like smoothies, coffee, or tea or added to food recipes. Collagen powder often have a neutral taste and dissolve easily, making them a popular choice for those who dislike swallowing pills.


  • Can be mixed into beverages or food
  • Generally tasteless and easily dissolvable
  • Faster absorption rate compared to pills


  • May require measuring or weighing for accurate dosage
  • Can be less portable than pills or liquids


Liquid collagen supplements typically have the fastest absorption rate, as they can be directly ingested and readily absorbed by the body. They're easy to consume and can be taken alone or mixed with a beverage. However, liquid collagen supplements may have a shorter shelf life than other forms, and some people may find the taste unappealing.


  • Fast absorption rate
  • Easy to consume
  • Can be taken on its own or mixed with a beverage


  • May have a shorter shelf life
  • Some people may dislike the taste
  • Can be less portable than pills

When choosing a collagen supplement, consider your preferences, lifestyle, and dietary restrictions. It's also important to select a high-quality supplement from a reputable brand to ensure the best results. Always consult with a healthcare professional before starting any new supplement regimen.

The Benefits of Collagen Supplements for Skin, Hair, Nails

Collagen supplements offer several potential skin, hair, and nail benefits. Here's an overview of some of the improvements you may experience after incorporating collagen supplements into your routine:

Improved Skin Elasticity

As we age, our skin loses its natural elasticity due to a decline in collagen production. Supplementing with collagen can help support your skin's structure and maintain its youthful elasticity. This can lead to firmer, smoother skin and a more youthful appearance.

Reduced Wrinkles

Collagen plays a vital role in maintaining the skin's structure, so when collagen levels decrease, the skin becomes more susceptible to fine lines and wrinkles. Taking collagen supplements may help reduce the appearance of wrinkles by supporting the skin's structure and promoting a more plump and hydrated appearance.

Stronger Nails

Collagen is an essential component of our nails, providing strength and resilience. Supplementing with collagen can help improve nail health by supporting the nail bed and promoting faster growth. As a result, you may experience stronger, healthier nails less prone to breakage and splitting.

Healthier Hair

Collagen provides essential amino acids and nutrients that support hair health, including the protein keratin, which is the building block of our hair. Supplementing with collagen may help promote hair growth, thickness, and overall health by providing the necessary nutrients and combating free radical damage that can lead to hair loss.

How to Choose the Best Collagen Supplements

When selecting a collagen supplement, consider the following factors to ensure you choose a high-quality product that meets your needs:


Look for products with minimal additives, such as artificial flavours, colours, or preservatives, and high-quality collagen sources. The best collagen supplements should contain hydrolyzed collagen or collagen peptides, which are more easily absorbed by the body.


Choose supplements derived from grass-fed, pasture-raised animals or sustainable marine sources. These sources tend to be of higher quality and are more environmentally friendly. Plant-based collagen alternatives, such as vegan collagen builders, may be suitable for those following a plant-based diet.

Brand Reputation

Opt for reputable brands with transparent manufacturing processes and positive customer reviews. Research the brand's history, certifications, and third-party testing to ensure the product meets high-quality standards.

Type of Collagen

As mentioned earlier, there are several types of collagen, with types I, II, and III being the most common. Consider which type of collagen is most suitable for your needs – for example, if you're primarily interested in skin health, a supplement containing type I collagen may be the best choice.


Bioavailability refers to how easily the body absorbs a substance. Look for collagen supplements with enhanced bioavailability, such as those containing hydrolyzed collagen or collagen peptides. These collagen forms are broken down into smaller particles, making them easier for your body to absorb and utilize.


While price shouldn't be the sole determining factor when choosing a collagen supplement, finding a product that offers good value for money is essential. Compare the price per serving or per gram of collagen to ensure you're getting a quality product at a reasonable price.

By considering these factors and consulting with a healthcare professional, you can make an informed decision when choosing the best collagen supplement. Remember, consistency is key – it may take several weeks or months of consistent use to see noticeable improvements in your skin, hair, and nails.

Side Effects and Safety Considerations

While collagen supplements are generally considered to be safe for most people, but there are some potential side effects and safety considerations to be aware of:

Digestive Discomfort

When taking collagen supplements, some individuals may experience digestive discomforts, such as bloating, gas, or stomach cramps. This can occur if your body is not used to digesting large amounts of protein or is sensitive to specific ingredients in the supplement. If you experience digestive discomfort, consider starting with a smaller dosage and gradually increasing it as your body adjusts.

Allergic Reactions

In rare cases, some people may experience an allergic reaction to collagen supplements, especially if they have a known allergy to the source of the collagen (e.g., fish, shellfish, or bovine). Symptoms of an allergic reaction can include hives, itching, swelling, difficulty breathing, or anaphylaxis. If you feel that you have an allergic reaction, discontinue use immediately and seek medical attention.

Interactions with Medications

Collagen supplements may interact with certain medications, such as blood thinners or calcium channel blockers. If you are taking any prescription medications, consult with a healthcare professional before starting a collagen supplement to ensure no potential interactions.

Pre-existing Conditions

If you have any pre-existing medical conditions, especially kidney or liver disease, it's essential to consult with a healthcare professional before starting collagen supplementation. Consuming large amounts of protein may put extra strain on your kidneys or liver, so it's crucial to ensure that supplementation is safe for your individual circumstances.

Pregnancy and Nursing

While there is limited research on the safety of collagen supplements during pregnancy or breastfeeding, it's always best to err on the side of caution. Consult with your healthcare provider before taking collagen supplements if you are pregnant, nursing, or planning to become pregnant.

By considering these safety considerations and consulting with a healthcare professional, you can make an informed decision about whether collagen supplementation is right for you. Remember, it's always best to prioritize a healthy diet and lifestyle to support your overall health and well-being.


Collagen supplements can help to improve skin, hair, and nail health by providing a range of essential nutrients. When choosing a collagen supplement, look for one that contains hydrolyzed collagen or collagen peptides for enhanced bioavailability. Compare the price per serving or gram of collagen to ensure good value for money. 

Make sure to consult with a healthcare professional to ensure you are choosing the right supplement for your needs and to consider any potential side effects or interactions with medications. 

Finally, remember that consistency is key – it may take several weeks or months of consistent use to see noticeable results. With these tips in mind, you can decide whether collagen supplementation is the best choice for you.
