"Collagen is the most abundant protein found in the human body, making up approximately 25-35% of your body's total protein content. This naturally occurring building block provides structural support to many tissues such as skin, connective tissue, bones, cartilage, muscle, tendons and ligaments," Richland told "Good Morning America."
"Some commonly cited benefits that collagen supplementation may provide may include improved skin elasticity and hydration, reduced wrinkles, expedited wound healing, stronger bones, increased bone density, reduced joint pain and improved nail and hair health," Richland said.
"Collagen supplements are generally considered safe," Richland said, "but risks exist, such as bloating, diarrhea, heartburn, rash, elevated liver tests and allergic response among others."
"Collagen supplementation may be beneficial to a wide range of patients, such as those who are looking for anti-aging benefits, improved bone strength and reduced joint pain," Richland said.
"The best forms of collagen supplementation come as hydrolyzed collagen (aka collagen peptides), or as capsules," Richland said. "You may also want to find a supplement that contains all three major types of collagen, including Type I, and Type III collagen for skin health and Type II collagen for bone/joint support."
