In reference to Dr. Newman's suggestion that pyridoxine, B6 suppresses
lactation. Yes, it has been reported.

Pyridoxine
Trade: Vitamin B-6, Hexa-Betalin
Uses: Vitamin B-6
AAP: Approved by the American Academy of Pediatrics for use in breastfeeding
mothers
Pyridoxine is the vitamin B-6. It is required in slight excess during
pregnancy and lactation. Very high doses (600 mg/day) suppress prolactin
secretion and therefore production of breastmilk. Do not use in excess of 10
mg/day and only in nutritionally deficient women. One study clearly indicates
that pyridoxine readily transfers into breastmilk and that B-6 levels in milk
correlate closely with maternal intake. Mothers who are deficient in
pyridoxine should be supplemented with modest amounts (< 25 mg/day).
