Could this be one reason why I have so many neurological symptoms with outbreaks....just a very long standing Niacin deficiency? High dose Niacin has been shown by Abram Hoffer in Niacin: The Real Story, to help many, many people who had been diagnosed with schizophrenia. High dose Niacin also helps survivors of concentration camps to restore the quality of their lives.
Lysine is one of 20 essential amino acids used by the body to grow and repair tissue. It cannot be stored and must be constantly replenished. When the body does not get enough lysine, the B Vitamin niacin becomes depleted and the disease of pellagra can result. Most people get sufficient lysine by eating proteins such as meat, cheese, nuts, eggs and soybeans. Those at most risk of lysine deficiency are vegetarians on macrobiotic diets and some athletes who deplete their lysine stores. Lysine stops the herpes virus from spreading and is now used to treat herpes, shingles and cold sores.
