There is a Lyme treatment protocol in which one takes high doses of both salt and vitamin C. Dr. Linus Pauling pioneered the use of high dose IV vitamin C for cancer treatment, but he used Sodium Ascorbate instead of Ascorbic Acid...
Also, Vitamin C does help connective tissue (collagen, etc.), bones, and other body tissues, and also supports the immune system. Vitamin C also reduces inflammation and fights viral infections.
And most people in the USA do not get much vitamin C in their diet because it is destroyed when foods are cooked. The RDA is pitifully low for vitamin C (60mg/day - barely enough to prevent scurvy), and exposure to environmental toxins, cigarette smoke, etc., can deplete this vitamin quickly. The body does not make its own vitamin C, so we must obtain it from food sources.
