Linus Pauling's last interview on Vitamin C:

PETER BARRY CHOWKA: Dr. Pauling, could you summarize the role that vitamin C plays in human health and its importance to the health of the nation as a whole?

LINUS PAULING, PhD: Vitamin C – ascorbic acid or sodium ascorbate or calcium ascorbate – is involved in a great number of biochemical reactions in the human body. Two of its major interactions are in potentiating the immune system and aiding the synthesis of the protein collagen, which is a very important substance that holds together the human body. Collagen strengthens the blood vessels, the skin, the muscles and the bones. You can’t make collagen without using up vitamin C.
