A practitioner asks: “What about using intravenous vitamin C for coronavirus infection?”

This is not essential, but it is more likely to be effective because it deals with the need to have high tissue levels of the vitamin in order to eradicate an ongoing viral infection. When an IV line is in place, it will be straightforward to deliver medication continually to provide a round‑the‑clock exposure for a sufficient duration to do what is needed to reach the organisms present and eliminate them. The drawback, of course, is the need for medical supervision and medical-grade equipment and professional knowledge. There are risks always with something that is invasive. There are quality control concerns and concerns about sterility. It would be tragic and quite ironic to deliver vitamin C for a viral infection but have someone develop complications from a secondary bacterial infection because of non-sterile solutions or equipment used with someone in a weakened condition.
