Aging
Alcohol

Hydrazine compounds
Hypoacidity (acid is necessary for vitamin B6 absorption)
L-canavanine compound - found in alfalfa
Maleica hydrazide - a plant growth regulator and herbicide
Monoamine oxidase inhibitors, isoniazid, theophyline and other anti asthma medications
PCB's (polychlorinated biphenols) - have been found in 99% of all Americans tested

2 - 5 gm. over a few months may result in numbness and tingling in the extremities - symptoms usually disappear after B6 is discontinued
Doses larger than 50 mg. per day may suppress lactation
Doses of 500 mg. per day or more for extended periods of time have been reported to cause sensory neuropathy in a stocking-glove distribution
Lower doses may cause insomnia or anxiety which may be prevented by co-administration of magnesium

L-Dopa - B6 converts L-Dopa into dopamine outside the blood brain barrier
Large doses may increase the need for magnesium, zinc, essential fatty acids, and other B vitamins
May prevent depression secondary to exogenous estrogens
Sinemet (L-Dopa and Carbidopa) - synergistic effect

Deamination - removal of amino groups from certain amino acids for energy
Decarboxylation - removal of COOH groups from certain amino acids to form another compound
Desulfuration - transfer sulfhydryl group (HS) from one amino acid methionine to another, serine, to form cysteine
Promotes release of glycogen from liver and muscle as glucose-1-phosphate
Required for formation of alpha aminolevulinic acid (precursor of heme in hemoglobin)
Required for formation of sphygolipids involved in development of myelin sheath
Required for series 1 prostaglandins (PGE 1) formation from linoleic acid
Required for synthesis of intrinsic factor
Required for synthesis of neurotransmitters serotonin, norepinephrine, histamine
Transamination - transfer of NH2 to other amino acids
