Some collagen supplements come from a chicken. This is because chickens have connective tissue in them. This tissue makes chicken a source of collagen from abundant food. Several studies have used a chicken neck and cartilage as the largest source of collagen.
Chicken contains type 2 collagen which is beneficial to the skin, and works by causing the body to produce substances that fight pain and swelling. Collagen in chickens is also often used to treat joint pain associated with many types of arthritis and surgery, as well as back pain, neck pain, and pain after an injury.
Vitamin C plays a major role in the production of pro-collagen, the body’s precursor for collagen. This vitamin also helps collagen production and therefore helps build and maintain skin, tendons, ligaments, blood vessels, and cartilage.
Therefore, getting enough vitamin C is very important. Oranges such as sweet oranges, grapefruit, lemons, and limes are full of these nutrients. One medium-sized orange has about 70 mg of vitamin C.
Especially sun-dried tomatoes, also contain high levels of vitamin C needed for collagen production. Tomatoes also contain the antioxidant lycopene, which is known to protect skin from sun damage and collagen damage.
If applied topically, vitamin C can help improve skin elasticity. Vitamin C in tomatoes can make skin tighter. Tomatoes are also rich in vitamin B. This vitamin has anti-aging properties that can help reduce age spots, fine lines, and wrinkles.
Spinach, kale, and mustard greens are rich in nutrients such as vitamin C and iron. Chlorophyll in green vegetables can increase the amount of procollagen (collagen precursor). Several studies have shown that consuming chlorophyll increases collagen precursors in the skin.
