Sure, I am just very skeptical of a lot medical research involving vitamins and your first link didn't work on my mobile and the second wasn't results, so I was hoping to see some legitimate studies.
I have firsthand seen several major shifts in vitamins and nutrition in medicine. For example, vitamin D was heavily promoted in the early 2000s for a lot of indications that appeared back by research that in the end was fraud (see https://www.sciencemag.org/news/2018/08/researcher-center-ep...).
Vitamin C also was heavily promoted by Linus Pauling but ended up being flat, although now we are seeing a resurgence in the belief that it plus thiamine and steroids can help with septic shock (look up https://journal.chestnet.org/article/S0012-3692(16)62564-3/f...). This is being heavily debated right now.
I looked at three papers in the first link but none showed actual results, just hypothetical improvements.
I'm happy it appears to be helping you CAC, how often are you getting CACs?
