Collagen: A New Wrinkle?

The Wall Street Journal: “Foods infused with collagen and touting beauty and health benefits have been popular in Japan and Europe for years. Now they are making a splash in the U.S., in products from coffee creamer to protein bars. The rise of collagen as a food ingredient also comes as the line between food and medicine is blurring, nutrition experts say, and consumers seek ‘functional foods’ that promise more than just nutrition.”

“A longstanding beauty ingredient in wrinkle creams, shampoos and lip injections, collagen makes up about a third of the human body’s proteins, and dwindles with age. As an ingredient, it is sourced from the bones, skin or cartilage of animals including pigs, cows, chicken and fish. These tissues are typically treated with enzymes, dried and processed into smaller molecules—or peptides—to help absorption by the body.”

“Experts say much of the research that has been done on collagen supplementation is small in scale and often funded by the ingredient makers themselves. ‘The research is not there,’ says Mark Moyad, a director of complementary and alternative medicine at the University of Michigan Medical Center … Dermatologists say there isn’t any conclusive evidence that ingested collagen affects the hair, skin and nails. When collagen reaches the stomach, it gets broken down into amino acids just like any other protein.”
