Vitamin C – Do We Need to Supplement?
Vitamin C (ascorbic acid) can be controversial. There is debate about how safe dietary supplements are and a lack of knowledge about how they are stored and used in the body.
Vitamin C is used in the body in several ways:
The formation of collagen, a protein from connective tissue that exists throughout our bodies. Vitamin C contains 4 hydroxyl groups (H2O) which can be added to collagen, changing its conformation, making it stronger. Collagen is involved in the function of blood vessels, tendons, ligaments, and bones, and contributes to a firm skin tone. Without it, we would fold and our blood vessels would leak.

Formation of norepinephrine, a neurotransmitter that affects our mood and ability to move. Some antidepressants increase norepinephrine levels.
The synthesis of carnitine, a molecule that transports fat to our mitochondria, increases our ability to burn fat. Carnitine deficiency can cause fatigue, one of the early symptoms of vitamin C deficiency scurvy.
As an antioxidant that protects our cells from damage caused by harmful free radicals. Its ability to regenerate other antioxidants such as vitamin E makes it very useful in this regard.
From the list above, you might conclude that it is helpful to have enough vitamin C in your body at all times.
Vitamin C storage.
Vitamin C is a water-soluble vitamin, and I've heard that the body excretes it easily through urine. That is not true. In fact, vitamin C is stored by most of the organs in our body, as well as in our blood plasma. Blood plasma levels are maintained at around 1.4 mg/dl. When they fall below this level, the kidneys reabsorb the vitamin C that penetrates them. If this renal reabsorption is exceeded, more vitamin C is reduced and excreted.
Our organs try to store vitamin C at significantly higher levels than in blood plasma. For example, the adrenal glands, pituitary gland, thymus, and retina have concentrations of vitamin C 100 times higher than blood plasma.
