Linus Pauling, a two-time Nobel Prize winner, especially praised the preventive and therapeutic effects of vitamin C on tumors. He believes that the human body is generally short of vitamin C. However, when the daily oral dose of vitamin C exceeds 250 mg, the level of vitamin C in serum will reach a plateau. Even if the intake is large, it is difficult to further increase the content of vitamin C in tissues and cells.

Using vitamin C as drug dosage, the concentration of vitamin C in tissues and cells can be greatly increased by intravenous administration, thus achieving therapeutic effect.
