The Top 5 Science-Backed Benefits of Collagen
Discover how this essential protein can transform your health from the inside out
Collagen is the most abundant protein in the human body, making up about 30% of your total protein content. It provides structure to your skin, bones, tendons, ligaments, and muscles. As we age, our bodies naturally produce less collagen, which can lead to various signs of aging and health issues. This is why collagen supplements have gained immense popularity in recent years.
Let's explore the top five scientifically supported benefits of incorporating collagen into your daily regimen.
Improved Skin Health and Elasticity
Collagen plays a crucial role in strengthening skin, plus may benefit elasticity and hydration. As we age, our bodies produce less collagen, leading to dry skin and the formation of wrinkles.
Several studies have shown that collagen peptides or supplements containing collagen may help slow the aging of your skin by reducing wrinkles and dryness. These supplements work by stimulating your body to produce collagen on its own. Additionally, collagen supplements may promote the production of other proteins that help structure your skin, including elastin and fibrillin.
The Science: Research has found that women who took a collagen supplement showed significantly improved skin elasticity compared to those who took a placebo. Additionally, studies have observed increased skin hydration and collagen density in the dermis layer after regular supplementation over 8-12 weeks.
Joint Pain Relief and Improved Mobility
Collagen helps maintain the integrity of your cartilage, which is the rubber-like tissue that protects your joints. As collagen production decreases with age, the risk of developing degenerative joint disorders such as osteoarthritis increases.
Consuming collagen supplements may help reduce joint pain and symptoms of osteoarthritis. The supplemental collagen may accumulate in cartilage and stimulate your tissues to make collagen, leading to lower inflammation, better joint support, and reduced pain.
The Science: Studies have shown that adults taking collagen supplements reported significant reductions in joint pain and were better able to engage in physical activity than those who did not take the supplements. Research particularly supports benefits for people with osteoarthritis and those with activity-related joint pain.
Stronger Hair and Nails
Many people take collagen to improve the health and strength of their hair and nails. Collagen provides the amino acids needed to build keratin, the protein that makes up hair and nails.
Regular collagen supplementation may increase the strength of your nails by preventing brittleness. Additionally, it may stimulate your hair and nails to grow longer and faster by providing the necessary building blocks for growth.
The Science: A study found that participants who took daily collagen supplements for 24 weeks experienced a 12% increase in nail growth rate and a 42% decrease in broken nails. Additionally, 80% of participants reported improved nail appearance and reduced brittleness by the end of the study period.
Improved Gut Health
Some health practitioners promote collagen supplements to treat intestinal permeability, sometimes called "leaky gut syndrome." This condition involves gaps in the intestinal walls that allow particles to pass into the bloodstream.
The amino acids in collagen, particularly glutamine, may support the intestinal lining and maintain gut barrier function. By strengthening the gut lining, collagen may help prevent leaky gut syndrome and associated inflammatory conditions.
The Science: While more research is needed, preliminary studies suggest that collagen peptides can help repair the intestinal lining by nourishing intestinal cells and reducing inflammation. Patients with inflammatory bowel conditions have shown improvements in digestive symptoms when supplementing with specific collagen peptides.
Increased Muscle Mass and Strength
Between 1-10% of muscle tissue is composed of collagen. This protein is necessary to keep your muscles strong and functioning properly. Research suggests that collagen supplementation, combined with resistance training, may help increase muscle mass and strength.
Collagen contains the amino acid glycine, which helps your body produce creatine. This may support muscle growth and athletic performance when combined with exercise. Additionally, collagen may promote the synthesis of muscle proteins like creatine, and stimulate muscle growth after exercise.
The Science: A study involving elderly men with sarcopenia (age-related muscle loss) found that those who took collagen while participating in a 12-week exercise program gained significantly more muscle mass and strength than those who exercised but didn't take collagen. The researchers suggested that collagen may promote the synthesis of creatine and other muscle proteins.
