Vitamin C, also called ascorbic acid, can cause bleeding if deficient. The first discovery of vitamin C deficiency was a ship voyage in England, and after a few months it was found that people who always ate lemons were not deficient in vitamin C, and their teeth and whole body did not bleed much, while those who did not eat them died of ischemia. So later it was found that vitamin C deficiency would cause bleeding, and at first there was lack of blood in the gums and other places, so at that time the name ascorbic acid was created. Vitamin C is water-soluble and is available today if it is supplemented, but not if it is not. That’s why many foods now have more vitamin C in them, such as lemons, oranges and other acidic foods. If you are deficient in vitamin C, you can supplement with Schilkhorn and SunCen, which both contain vitamin C.
