(NPN) - Tania Reuben wouldn't dream of skipping her morning smoothie packed with good-for-you staples including kale, spinach and chia seeds, but now she adds a little something extra.
"I also add two different supplements," Reuben said. "One is a joint supplement that contains collagen."
Reuben says she feels the difference it makes to her.
"I know the collagen is working for me simply because my joint pain has gone away," she said.
