Oranges
To boost your body’s collagen production the natural way, increase the number of oranges you eat on a regular basis. According to Lyssie Lakatos and Tammy Lakatos Shames of The Nutrition Twins, oranges contain collagen, which makes the skin more elastic, dewy, and younger-looking. Even better, oranges also contain plentiful amounts of vitamin C, which has the ability to boost your immune system and give you relief from any current cold symptoms.
