Research, Benefits and Cautions.

Vitamin C is essential for the manufacturing of collagen, necessary for tissue repair. It is needed for metabolism of phenylalanine, tyrosine, folic acid, iron.

It promotes the production of red-blood-cell in bone marrow. Ascorbic Acid also supports healthy capillaries, gums, teeth, and even helps heal wounds, burns, and broken tissues. It contributes to hemoglobin and red-blood-cell production in bone marrow while even preventing blood clots. The list goes on. It helps heal urinary-tract infections, and helps treat anemia.
