Collagen protein is found abundantly in the human body. The word collagen is derived from the Greek word kola, meaning “glue.” Collagen is the foundational “glue” that helps hold the body’s flesh and connective tissues together. Collagen is found in hair, nails, skin, muscle tissue, blood vessels, and bones. Tendons, cartilage, the digestive tract, heart, kidneys, gallbladder, and other organs also contain collagen. Collagen gives our skin elasticity and strength. It even plays an integral part in helping our bodies replace dead skin cells.
Collagen comprises nearly one-third of the body’s protein content, with 90% of the collagen types 1, 2, and 3 collagen.(1, 2) Over time, the body’s production of collagen slows, which is when dietary supplementation can play a role. As consumer awareness of collagen supplementation in health and personal care grows, along with expanding nutraceutical products, market researchers predict a strong collagen market. Global Market Insights’ “Competitive Market Share & Forecast 2016 – 2023” estimates that the global collagen market, valued at more than $3 billion in 2015, is likely to exceed $5 billion by 2023, with a CAGR of 7% between 2016–2023, with growth expected for gelatin, collagen peptides, and marine collagen markets.
“The market for collagen products is on the rise in the U.S.,” says Katie Stevenson, business development manager, Nitta Gelatin NA Inc. (Morrisville, NC). “Innovative applications that we see driving growth this year include ready-to-drink products and gummies, as well as shots containing collagen for beauty-from-within, joint health, overall health and wellness, and as a protein source.”
