Vitamin B6

From Freepedia

The two major forms of vitamin B₆ are pyridoxine and pyridoxamine. In the liver they are converted to pyridoxal 5'-phosphate (PLP) which is a cofactor in many reactions of amino acid metabolism. PLP also is necessary for the enzymatic reaction governing the release of glucose from glycogen.

Pyroluria is one potential cause of vitamin B₆ deficiency. An overdose of pyridoxine can cause a temporary deadening of certain nerves such as the proprioceptory nerves; causing a feeling of disembodiment common with the loss of proprioception.

At least one preliminary study has found that this vitamin may increase dream vividness or the ability to recall dreams^[1]. It is thought that this effect may be due to the role this vitamin plays in the conversion of tryptophan to serotonin^[2].
