Yes, you are EXACTLY correct. To quote Dr. Levy again, "The three most important considerations in effective vitamin C therapy are "Dose, Dose, and Dose." If you don't take enough, you won't get the desired effects. Period!...you will rarely ever fail to observe a DRAMATIC response...IF you take a large enough dose for a long enough time."
As "grist for your mill," Pablo, I myself ingest well in excess of 50 grams of ascorbic acid per day. That is my Bowel Tolerance limit. Yours could be more or less. The health results to me [at the age of 64] are: never get sick [including even a headache]; never have need of doctors [the occasional dentist excepted]; never ingest any drugs whatsoever, be they over-the-counter or prescription, including any and all painkillers [the occasional novocaine injection excepted].
If you have any questions, comments, and/or concerns, Pablo, please feel free to post them or contact me.
I wish you the best of success in resolving your health issues!
