Collagen supplementation is the practice of taking collagen in the form of a supplement to potentially improve the health and appearance of the skin, hair, and nails among other things. In this article, we will explore the benefits of collagen supplementation and how it may support overall health and wellness.
What is Collagen?
Collagen is a protein that is found throughout the body and plays a vital role in maintaining the structural integrity of tissues such as skin, hair, nails, bones, and connective tissue. It’s the most abundant protein in the human body, comprising about 30% of the total protein content.
What Does Collagen Do?
Collagen comprises long chains of amino acids, specifically glycine, proline, hydroxyproline, and arginine. These amino acids give unique collagen properties, such as their strength and ability to support the body’s tissues.
Types Of Collagen
There are 28 different types of collagen in the human body, but the five most common are:
Collagen type I is found in many different connective tissues and organs in the body, including the skin, tendons, ligaments, bones, and teeth. It is essential for maintaining the structural integrity of these tissues and for supporting their proper functioning.
Collagen type II is a form of collagen that is found in cartilage, the tissue that cushions and protects the joints. It is responsible for giving cartilage its elastic and flexible properties, which help to cushion and protect the joints during movement.
This type of Collagen helps to support the dermis (middle layer) and contributes to the skin elasticity and smooth appearance. It is also found in the walls of blood vessels and in the muscles, where it helps to provide support and protection.
Collagen type IV helps to support the basal lamina (bottom layer) of the epidermis (top layer) and contributes to the skin’s structural integrity. It is also found in the walls of blood vessels, where it helps to provide support and protection. Collagen type IV is also important for the proper functioning of the kidneys and liver, where it helps to filter waste products from the blood.
This type of collagen provides structure of our bone, the cornea layer, and the interstitial tissue of muscles, the liver, the lungs, and the placenta.
What are Collagen Supplements?
Collagen supplements are products that are taken orally or applied topically to potentially support the body’s collagen production and improve the health and appearance of the skin, hair, and nails. Collagen supplements are available in a variety of forms, including capsules, powders, and topical creams.
There are several ways in which collagen supplements can be made. One method involves extracting collagen from animal sources such as cows, pigs, or fish. This type of collagen is known as hydrolyzed collagen or collagen peptides. It is made by breaking down the collagen protein into smaller peptide chains through a process called hydrolysis. This makes the collagen more easily absorbed by the body.
Another method of making collagen supplements involves the use of plant-based ingredients that are believed to support collagen production in the body. These types of collagen supplements are usually made from a combination of plant extracts, vitamins, and minerals that are believed to support the body’s natural collagen production.
Health Benefits of Collagen Supplements
There are several potential health benefits of collagen supplements that have been supported by scientific research. Here are some of the proven benefits of collagen supplementation:
Improved Skin Health
Collagen is a key structural protein that helps to keep the skin looking youthful and smooth. Some studies have shown that collagen supplements can improve skin moisture, and elasticity, and reduce the appearance of wrinkles and fine lines.
Collagen is a major component of cartilage, the tissue that cushions and protects the joints. Studies have shown that collagen supplements may help to improve joint health, reduce joint pain and stiffness, and decrease the risk of developing osteoarthritis.
Collagen is also important for the health and strength of bones. When you grow older, our body produces less collagen so taking oral collagen supplements may help to improve bone density and reduce the risk of osteoporosis, especially in postmenopausal women.
Collagen is found in the lining of the digestive tract, which helps to support the barrier function and protect against leaky gut syndrome. Collagen may help improve gut health and reduce the risk of digestive issues.
Collagen supplements may help to increase the feeling of fullness and reduce appetite, which may lead to a reduction in calorie intake and ultimately, weight loss. Collagen supplements may also help to improve muscle mass and metabolism, which may support weight loss efforts.
Collagen supplements may help to strengthen the nails, making them less prone to breakage and splitting. They may also help to improve the moisture content of the nails and surrounding skin, making them less prone to dryness and brittleness.
Studies have suggested that collagen supplements may promote healthy blood vessels and reduce the risk of heart-related conditions such as high blood pressure and atherosclerosis (hardening of the arteries).
As with any supplement, it is important to talk to a healthcare provider before starting collagen supplementation to ensure it is safe and appropriate for you.
How Long Do Collagen Supplements Take Effect
It is generally thought that it may take at least 8 weeks for the effects of collagen supplements to become noticeable in the skin and joints.
However, it is important to note that the length of time it takes for collagen supplements to take effect can vary and may depend on several factors such as the type and dosage of the supplement, the individual’s age, and overall health, and the specific health condition being addressed.
Some people may notice improvements in the appearance and health of their skin, hair, and nails within a few weeks of starting collagen supplements, while others may take up to a few months to notice these changes.
Factors in Choosing Collagen Products
It is generally recommended to look for collagen supplements that come from grass-fed, pasture-raised animals or wild caught fish. These sources of collagen may be higher in quality and have a more favorable nutrient profile compared to collagen from conventionally raised animals.
It is also important to look for collagen supplements that DON’T contain any additives or additional fillers, as these may compromise the quality or effectiveness of the product. Look for manufacturers of collagen that uses high-quality ingredients and follows good manufacturing practices.
Collagen powder is made by processing collagen from animal sources or from marine sources, such as fish. The collagen is then ground into a fine powder and can be mixed into beverages or added to food. Collagen powder is typically flavorless and has a neutral taste, making it easy to incorporate into a variety of recipes.
It’s typically recommended to be taken in doses of 2 to 15 grams of collagen per day. It can be mixed into beverages, such as water, juice, or smoothies, or added to food, such as oatmeal, soups, or baked goods. Some people may prefer to take collagen powder in divided amount of collagen doses throughout the day, while others may prefer to take it all at once.
What Food Items Contain Collagen? (Sources of Collagen)
While taking supplements containing collagen are a convenient way to increase collagen intake, there are also many foods that contain collagen naturally.
Here are some examples of foods rich in collagen:
- Bone broth: Bone broth is made by simmering bones and connective tissue in water for an extended period of time. The cooking process breaks down the collagen in the bones and connective tissue, making it easily digestible and bioavailable.
- Fish: Fish, particularly salmon, halibut, and cod, are good sources of collagen. Fish collagen is similar in structure to human collagen and may be easier for the body to absorb and use.
- Eggs: Eggs are a good source of collagen-building amino acids such as proline and lysine. The egg whites are particularly high in collagen-building amino acids.
- Citrus fruits: Citrus fruits, such as oranges, lemons, and limes, are rich in vitamin C, which is important for collagen synthesis. Vitamin C helps to activate collagen production and may help to improve the appearance and health of the skin.
- Berries: Berries, particularly strawberries and raspberries, are high in antioxidants, which may help to protect the collagen in the skin from damage caused by free radicals.
- Red and yellow vegetables: Vegetables such as tomatoes, carrots, and peppers are high in carotenoids, which may help to support collagen synthesis and improve the appearance of the skin.
In addition to incorporating collagen-rich foods into your diet, it’s also important to follow a healthy, balanced diet and engage in regular physical activity to support overall health and wellness.
Potential Side Effects of Collagen Supplements
Most collagen supplements are generally considered to be safe. However, as with any dietary supplement, there is a potential for side effects.
Some possible side effects of collagen supplements include:
- Digestive symptoms: Some people may experience digestive symptoms such as bloating, gas, or diarrhea after taking collagen supplements. These symptoms may be more likely to occur if the collagen supplement is not taken with food or if the dosage is too high.
- Allergic reactions: Collagen supplements are often derived from animal sources, such as cowhide or chicken bones, however they may contain allergens such as dairy or soy as additives. Some people may be allergic to these allergens and may experience symptoms such as hives, rash, itching, or difficulty breathing after taking collagen supplements.
- Drug interactions: Collagen supplements may interact with certain medications, such as blood thinners or nonsteroidal anti-inflammatory drugs (NSAIDs). It is important to talk to a healthcare provider if you are taking any medications to ensure that collagen supplements are safe and appropriate for you.
- Pregnancy and breast-feeding: There is limited evidence on the safety of collagen supplements during pregnancy and breastfeeding. It is generally recommended to avoid taking collagen supplements or any other dietary supplements during these times unless specifically directed by a healthcare provider.
If you experience any side effects after taking collagen supplements, it is important to stop taking the supplement and talk to a healthcare provider.
