Thank you! What I appreciated about this piece is that it is very clear about how you actually think in practice rather than keeping vitamin C in the realm of vague theory. The article is strongest when it connects dosing, bowel tolerance, formulation, and clinical context into a coherent framework, because that gives readers a tangible sense of how you approach this tool rather than simply praising it in the abstract. I also appreciated the transparency around financial disclosure and the repeated reminders that this reflects your clinical perspective rather than established standard treatment, which adds an important layer of honesty to a topic that is often discussed with too much certainty. 
One place where I think the piece could become even stronger is in separating more explicitly what comes from historical orthomolecular experience and patient feedback from what is supported by stronger modern clinical trial evidence. The references to Klenner, Pauling, and more recent physician experience are interesting and certainly part of the history of this conversation, but the article would become even more persuasive if readers were given a sharper evidence hierarchy around claims for acute infection, injury, and other high-stress states. That added calibration would not weaken the argument; it would likely strengthen trust, especially for medically literate readers trying to distinguish physiologic plausibility, clinical observation, and established standard-of-care evidence. 
Overall, I thought this was an engaging and valuable piece because it invites readers to think about vitamin C not as a simplistic wellness cliché, but as a dose-, context-, and formulation-dependent intervention. Even where one may want more careful evidence-grading, the post clearly reflects serious clinical curiosity and a desire to help people think more precisely about how supportive therapies are actually used in real-world practice. Thought-provoking and well worth the read!
I did purchase the exact vitamin C powder you recommend. My dosing is 1 teaspoon twice a day. I started off rather badly, I was using the wrong measuring spoon and was actually dosing about a half a tablespoon when I was doing my initial trial for tolerance. That led to some serious discomfort with trips to the toilet! But now I have settled on a teaspoon in the morning and a teaspoon in the afternoon. I’m now considering increasing that to 1 teaspoon three times a day. It is extremely inconvenient to travel with it, however. Do you have any suggestions for that? The airport called my bag aside at security to make sure I did not have contraband.
Hi Dr Stillman, I’ve been trying to figure out if there are people with underlying conditions that struggle to tolerate vitamin C. Can you shed any light? Or is it generally well tolerated by all populations?
Hi, Dr. Stillman... wanted to purchase some Vit C from your online store... SOLD OUT. 😩

I have a question. Why do I feel so good for a couple of hours after my vitamin C dosing?
