Pyridoxidine Hydrochloride(B6) Hazardous Substance Data Bank Number: 1212
		Pyridoxidine Hyrochloride is a synthetically produced chemical, generally produced through the condensation of cyanoacetamide (a cyanide containing chemical) & ethoxyacetalcetone.  Because this form of B6 contains hydrochloride, when heated to decomposition it emits very toxic fumes of oxides of nitrogen and hydrogen chloride.  Although this toxic decomposition may not occur in the human body after ingestion, it indicates just how synthetically produced vitamins act more like chemicals, and less like nutrients which are generally benign. Extremely large doses in range of 2 to 6 g/kg produce convulsions & death in rats and mice.  Lower doses (50mg injections) have interfered with the endocrine system of rats by suppressing pituitary secretions.
