Here’s another thing you might not have known about vitamin C: This nutrient is what helps link amino acids during collagen production. People usually consider citrus fruits to be the king of vitamin C.
But other fruits and vegetables have been found to carry much more. Still, one medium-sized orange has about 70mg of vitamin C. That’s decent, considering the recommended daily value for an adult woman is 75mg.
Scramble them, fry them, boil them. Just remember to eat the yolk. That gooey yellow center contains collagen that helps keep your hair nice and shiny. The egg whites also carry the amino acids needed to make collagen.
