Collagen is still a red-hot functional ingredient that is showing up in more and more food and beverage products. But this isn't the only space where collagen is cornering an important share of the market. According to Claire Morton Reynolds, Nutrition Business Journal's senior analyst, collagen supplements are projected to reach $298 million in sales in 2020, up from just $73 million in 2015.

As applications in natural foods and beverages become more varied and creative, functional foods containing collagen are becoming much more appealing and easy to incorporate into everyday eating. 

These eight products highlight some of the seriously tasty ways that health-conscious consumers can add more collagen into their diets.
