Collagen is a protein that makes up about 30% of the total protein in your body. It’s found in your skin, bones, muscles, tendons, ligaments, and other connective tissues. Collagen gives your skin its elasticity and strength, your bones their density and resilience, and your joints their flexibility and cushioning. But as you age, your collagen production declines, leading to signs of aging such as wrinkles, sagging skin, joint pain, and bone loss. Fortunately, you can boost your collagen levels by consuming collagen-rich foods or taking collagen supplements. Collagen supplements are made from animal sources such as cowhide, fish skin, or chicken bones. They are hydrolyzed, which means the collagen is broken down into smaller peptides that are easier to absorb.
Collagen supplements may have several health and beauty benefits, such as:
Improving skin health
Collagen is essential for maintaining healthy and youthful skin. It helps keep your skin hydrated, firm, smooth, and elastic. Studies have shown that taking collagen supplements can improve skin hydration, elasticity, roughness, and density. Collagen supplements may also reduce wrinkles and fine lines by stimulating the production of new collagen and other skin components such as elastin and hyaluronic acid.
Relieving joint pain
Collagen is also important for keeping your joints healthy and functional. It helps protect your cartilage, which is the rubber-like tissue that cushions your bones at the joints. As you age, your cartilage wears down and becomes thinner, causing joint pain and stiffness. Collagen supplements may help reduce joint pain and inflammation by stimulating the synthesis of new cartilage and preventing its breakdown. Collagen supplements may also improve joint mobility and flexibility by lubricating your joints and reducing friction.
Preventing bone loss
Collagen is a major component of your bones, giving them their structure and strength. As you age, your bone mass decreases, making them more fragile and prone to fractures. Collagen supplements may help prevent bone loss by increasing bone mineral density and inhibiting bone resorption (the process of breaking down bone tissue). Collagen supplements may also promote bone formation by activating osteoblasts (the cells that build new bone tissue).
Boosting muscle mass
Collagen is also found in your muscles, where it helps maintain their structure and function. Collagen supplements may help boost muscle mass by stimulating muscle protein synthesis (the process of creating new muscle tissue) and preventing muscle breakdown (the process of losing muscle tissue). Collagen supplements may also enhance muscle strength and performance by improving blood flow and oxygen delivery to your muscles.
Promoting heart health
Collagen is also present in your blood vessels, where it helps keep them strong and flexible. Collagen supplements may help promote heart health by lowering blood pressure and cholesterol levels, reducing arterial stiffness and plaque formation, and improving blood circulation and endothelial function (the function of the inner lining of your blood vessels). Collagen supplements may also protect your heart from oxidative stress (the damage caused by free radicals) and inflammation (the body’s response to injury or infection).
However, the benefits of collagen supplements are still debated, and more research is needed into less well-understood benefits, such as lowering blood sugar levels, improving gut health, enhancing brain function, supporting hair growth, and aiding weight loss.
Collagen supplements are generally safe and well-tolerated by most people. However, some people may experience side effects such as digestive issues (bloating, gas, diarrhea), allergic reactions (rash, itching), or a bad taste in the mouth. Collagen supplements may also interact with some medications or dietary supplements. Therefore, it’s advisable to consult your doctor before taking collagen supplements if you have any medical conditions or allergies or are taking any medications or supplements.
Collagen supplements are available in various forms such as powders, capsules, liquids, gummies, or bars. You can choose the form that suits your preference and convenience. The recommended dosage of collagen supplements varies depending on the product and the purpose, but generally ranges from 2.5 to 15 grams per day. You can take collagen supplements at any time of the day, with or without food. However, some experts suggest taking collagen supplements on an empty stomach or before bedtime to maximize absorption and effectiveness.
Collagen supplements are not the only way to boost your collagen levels. You can also increase your collagen intake by eating foods that contain collagen or promote collagen synthesis. Some of these foods include:
- Bone broth: a liquid made by simmering animal bones and connective tissues, which is rich in collagen and other nutrients such as amino acids, minerals, and vitamins.
- Gelatin: a substance derived from collagen that is used as a thickener or gelling agent in foods such as jello, marshmallows, and gummy candies. Gelatin contains the same amino acids as collagen and may have similar benefits.
- Animal skin and ligaments: the parts of animals that are high in collagen, such as chicken skin, pork skin, beef tendon, and fish skin. These foods are often used in soups, stews, or snacks.
- Vitamin C-rich foods: fruits and vegetables that are high in vitamin C, such as citrus fruits, berries, kiwi, broccoli, bell peppers, and kale. Vitamin C is essential for collagen synthesis and may also protect collagen from damage by free radicals.
- Other nutrients: foods that provide other nutrients that are important for collagen production or protection, such as zinc (oysters, beef, pumpkin seeds), copper (liver, nuts, chocolate), manganese (nuts, legumes, whole grains), selenium (Brazil nuts, seafood, eggs), antioxidants (berries, green tea, dark chocolate), and omega-3 fatty acids (fish oil, flaxseeds, walnuts).
In addition to consuming collagen or collagen-boosting foods, you can also prevent collagen loss by avoiding factors that damage or degrade collagen, such as:
- Smoking: a habit that exposes your body to harmful chemicals that impair collagen synthesis and increase collagen breakdown. Smoking also reduces blood flow to your skin and other tissues, depriving them of oxygen and nutrients. Smoking can cause premature aging of your skin and increase your risk of cardiovascular diseases.
- Sun exposure: a factor that exposes your skin to ultraviolet (UV) rays that damage collagen fibers and activate enzymes that degrade collagen. Sun exposure can cause wrinkles, sagging skin, age spots, and skin cancer. You can protect your skin from sun damage by wearing sunscreen with SPF 30 or higher, wearing protective clothing and accessories (hat, sunglasses), and avoiding sun exposure during peak hours (10 a.m. to 4 p.m.).
- Sugar intake: a factor that increases your blood sugar levels, which can lead to a process called glycation. Glycation is when sugar molecules attach to proteins such as collagen and form harmful compounds called advanced glycation end products (AGEs). AGEs can make collagen stiff and brittle and impair its function. Sugar intake can also cause inflammation and oxidative stress in your body, which can damage collagen and other tissues. You can limit your sugar intake by avoiding added sugars in foods and beverages such as soda, candy, cookies, cakes, ice cream, and fruit juices. You can also choose natural sweeteners such as honey or stevia instead of refined sugar.
Collagen is a protein that plays vital roles in your health and beauty. Collagen supplements may have several benefits for your skin, joints, bones, muscles, heart, and more. However, more research is needed to confirm some of these benefits and determine the optimal dosage and duration of use. Collagen supplements are generally safe but may cause some side effects or interactions in some people. You can also boost your collagen levels by eating foods that contain or promote collagen synthesis or by avoiding factors that damage or degrade collagen. If you want to improve your health and beauty with collagen supplements or foods, you can consult your doctor or nutritionist for the best advice and guidance.
