Vitamin C Benefits from Another Medical Scientist

Vitamin C is largely ignored by the medical community. High dose vitamin C is considered even outrageous.

"High dose" is really a misnomer. A better term would be "adequate dose."

Why would it be that a size convenient for swallowing has to be the right amount? In some respect, the more of something that is required, the potentially more important it is because of this "great" need. Vitamin C, in my experience, works best to prevent the duration of viruses (the common cold is comprised of many viruses from different families).

4 grams (capsules, pills) - 3 times/day.

Daily, without any symptoms, the right amount is probably 1-3 grams. I, personally, don't take vitamin C daily because of a high consumption of foods high in vitamin C. But when I feel something "coming on," I go right to the high dose.

Here is some vitamin C research, published in mainstream medical journal, assembled by another medical scientist.


Treatment with intravenous vitamin C reduced death rates in patients with sepsis and severe acute respiratory failure.

Sepsis is a potentially life-threatening condition caused by the body’s innate immune response to acute infection. Under some circumstances, aspects of this response that are typically associated with defense against infection can induce extensive cell and tissue damage, leading to multiple organ failure, the hallmark of sepsis. Acute respiratory distress syndrome (ARDS) is a common sepsis-associated organ injury that can lead to respiratory failure and death. A 2019 phase 2 trial found that intravenous vitamin C reduced death rates among patients with sepsis and ARDS. 

The randomized, double-blind, placebo-controlled, multicenter trial took place in seven medical intensive care units in the United States over a period of three years. The study participants included 167 male and female patients (average age, 55 years) with sepsis and ARDS. Every six hours for four days, the patients received either intravenous vitamin C (50 milligrams per kilogram of body weight) or a placebo. 

The authors of the study noted a substantial difference in the death rates among the two groups. Whereas approximately 30 percent of patients who received intravenous vitamin C died, more than 46 percent of patients who received the placebo died. Patients who received vitamin C also had fewer ventilated days, spent less time in intensive care (seven days versus ten), and their hospital stays were approximately one week shorter than those who received the placebo. 

These findings suggest that intravenous vitamin C administration might be beneficial in critically ill patients who have sepsis and respiratory failure. 


Large doses of vitamin C up to 8 grams per day might reduce the duration of the common cold.

The bulk of scientific research on the effectiveness of vitamin C in fighting infection has centered on reducing the symptoms and duration of the common cold, with mixed results. Most of these studies have used doses of approximately 1 gram per day, however. Findings from a 2017 study suggest that much larger doses might be more effective at reducing a cold’s duration.
