Thanks, Owen. Yes, we have corresponded quite a lot over the years. I've always found great support here. To be completely candid, I don't know how much vitamin C I've taken since I started reading Pauling circa 1983. Now I take about three heaping teaspoons per day, sometimes more, sometimes a bit less. When I've been ill I've taken as much are 5-6 teaspoons per day. I've persisted with lysine and proline. I've always used ascorbic acid.
My wife and I have been reviewing the history of my bloodwork and CAC scans. The calcium trouble started about 2010. I didn't connect the rising CAC score to a root canal tooth that was done a year or two earlier, but the scan in 2011 was 250, and three years later it was 550. The increases during that period were well above 15%.
I was trying everything, including PT, vitamin K, all kinds of vitamins and minerals. The score went up another 100 points the following scan, but then I read Dr. Thomas Levy about root canals and heart disease. I got the root canal tooth removed and things backed off for a year, only 28 points increase. Unfortunately, during the following interval, I took antibiotics for shingles and then for a UTI. This now seems related to resumed increase of about 100 points per year.
In January 2018, I started the vegan diet, after reading Drs. Esselstyn, McDougall, and Ornish. In September the CAC score actually decreased by nearly 100 points. Big success! When the score went back up by 100 points the following year, I was more than a little perplexed. Now it does appear that the antibiotic likely disturbed my gut flora and inflammation resulted in more CAC.
The most recent scan only increased by 48 points, something near 5% at my current CAC level.
One question about vitamin K. I've been taking the high potency koncentratedk for about five years, but with the other interference I don't know if I'm absorbing it. The question is whether I'm getting enough fat in my diet to absorb vitamins K, D, E, and A and other minerals. I take magnesium glycinate and a combined mineral supplement, Remyte. I've seen a product called Blue Ice Royal
https://www.rnareset.com/collections/frontpage/products/blue-ice-royal-butter-oil-fermented-cod-liver-oil-blend?variant=742010486803 that is supposed to solve the absorption issue.
