Help teeth and bone development
Vitamins can also promote bone metabolism and the production of collagen fibers, both of which are very important for the development of children’s bones and teeth, so it is very important to take vitamin C especially when children grow up.The development of a child’s bones is a very important part of the child’s growth process. Parents and friends cannot ignore it. They must urge their children to eat more vegetables and fruits during this period, along with vitamin C.
What is the role of vitamin C? Top medical journals give answers one by one!
《Nature》
On August 21, 2017, the British scientific journal Nature published an article on “Vitamin C regulates hematopoietic stem cell function and leukemia.” The Agathocleous research team found that vitamin C can regulate the function of hematopoietic stem cells and affect the formation of leukemia.
The researchers found that hematopoietic stem cells are enriched in ascorbate (vitamin C), and the higher the degree of cell differentiation, the lower the vitamin C content. When vitamin C is at a low level, the number of hematopoietic stem cells increases significantly, and the risk of leukemia increases.
In animal models, feeding vitamin C before leukemia in mice significantly inhibited tumorigenesis. Restoring vitamin C intake can increase the survival time of leukemia mice and has a significant therapeutic effect.
《Cell》
American medical journal “Cell” vitamin C can inhibit the progress of leukemia
On August 16, 2017, the American medical journal “Cell” published a research article on vitamin C. Cimmino’s research team found that vitamin C can inhibit the proliferation of hematopoietic stem cells, promote cell apoptosis, and inhibit the occurrence of blood tumors.
The study pointed out that the TET2 mutation gene is a common type of gene mutation in leukemia, which can promote the transformation of normal cells to cancer cells. Vitamin C can significantly inhibit the proliferation of hematopoietic stem cells, reduce the level of white blood cells, and inhibit the process of leukemia.
《Cancer cell》
Medical journal “Cancer cell” Vitamin C has the effect of inhibiting cancer cells
In 2017, the medical journal Cancer cell published a study on vitamins. Studies have found that vitamin C may have the effect of inhibiting cancer cells.
The study found that high-dose vitamin C in the treatment of cancer has been tested by phase I clinical trials. It is safe to routinely inject 800-1000 times the recommended daily average vitamin C content into brain cancer and lung cancer patients, and can change intracellular Fe (iron). ) metabolism, inducing the production of reactive oxygen species, causing specific DNA damage in cancer cells to cause cancer cell death, and achieving effective cancer treatment. After treatment, the patient’s survival was significantly prolonged, and the tumor was significantly smaller.
