Interactions
synergistic. B6 enhances cellular magnesium uptake and retention; magnesium-B6 combination is more effective than either alone for stress and anxiety in clinical trials
synergistic. B6 (PLP) enhances zinc absorption by forming absorbable zinc-PLP complexes in the intestine; both support immune function and neurotransmitter synthesis
inhibits. B6 accelerates peripheral decarboxylation of levodopa to dopamine, reducing the amount reaching the brain; this does not apply when levodopa is combined with carbidopa
inhibits. High-dose B6 (>200mg) may increase phenytoin metabolism, reducing its anticonvulsant effect
