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).
