Vitamin B6 is widely distributed in food and is dephosphorylated by alkaline phosphatase in the gut for absorption.
Following absorption ATP dependent phosphorylation restores phosphate ester forms. Deficiency of Vitamin B6 leads to increased homocysteine levels. Iron absorption is also compromised.
Use of mega dose Vitamin B6 (up to 6000mg/day compared with a reference nutrient intake several order of magnitude lower) has been described eg. Type 1 primary hyperoxaluria (AGT enzyme needs Vitamin B6 as cofactor), Idiopathic carpal tunnel, PMT, Schizophrenia, Autism Vit B6 toxicity results in peripheral neuropathy and encephalopathy. Elevated Vitamin B6 may be seen with hypophosphatasia (low alkaline phosphatase).
