Your bones are made up of specialized cells, called osteoblasts, surrounded by an extracellular matrix. Collectively, these components of bone tissue generate hard and strong bones that can renew and repair themselves. Following injury, your body deposits new bone tissue at the injury site to repair any fractures and restore proper bone function. This healing process relies on a number of factors, including the presence of essential vitamins obtained from your diet.
One vitamin that can aid in bone healing is vitamin C, or ascorbic acid. It is essential for the formation of collagen, reports the Linus Pauling Institute at Oregon State University, which is a structural protein found in several tissues throughout the body, including bones. Collagen fibers provide tensile strength to bone tissue, preventing the fractures that can occur from abnormally brittle bones. During bone healing, the synthesis of new collagen fibers allows for strong bone regrowth and healing. Eat foods rich in the vitamin, such as grapefruits, oranges, tomatoes, bell peppers and pineapple to consume adequate levels of vitamin C and support proper collagen production.
Another vitamin involved in bone healing is vitamin D, or calcitriol. Vitamin D plays a role in regulating bone regrowth after injury by helping your body absorb calcium, a mineral that makes up a portion of bone tissue. Calcium is found in hydroxyapatite, the substance that provides strength and hardness to bone tissue. During bone regrowth, the deposition of new hydroxyapatite helps close bone fractures, repairing the injury. Colorado State University indicates that vitamin D helps maintain a proper calcium and phosphorus balance in your body, allowing for efficient formation of mineralized bone tissue. Your body produces vitamin D upon exposure to sunlight and it is also found in fortified foods, such as milk. People in higher latitudes maybe require vitamin D supplementation due to lower sun exposure.
Vitamin K may also aid in bone regrowth. The Linus Pauling Institute explains that vitamin K has the ability to interact with a number of proteins in your body, including proteins involved in bone growth. Specifically, vitamin K helps regulate the activity of compounds that promote bone mineralization. In response to bone damage, the action of vitamin K supports normal bone regrowth, helping your bones deposit new mineralized tissue to close and heal and bone fractures. Including foods rich in vitamin K, such as olive oil, broccoli and green leafy vegetables, can help ensure you consume enough vitamin K each day to support proper bone regrowth.
