                                Early studies from the 1970s suggested that very high doses of pyridoxine, or vitamin B6, could suppress lactation by inhibiting prolactin, but newer research and consensus indicate this method is unreliable and unsafe. This has led many to question, 'Can vitamin B6 dry up breast milk?'—a claim healthcare professionals strongly caution against.
