Studies on B6 Effectivness on Prolactin
--------------------------------------------------------------------------------
======================================
J Clin Endocrinol Metab 1976 Mar;42(3):603-6
Effect of pyridoxine on human hypophyseal trophic hormone release: a possible stimulation of hypothalamic dopaminergic pathway.
Delitala G, Masala A, Alagna S, Devilla L.
A single dose of pyridoxine (300 mg iv) produced significant rises in peak levels of immunoreactive growth hormone GH and significant decrease of plasma prolactin PRL in 8 hospitalized healthy subjects. Serum glucose, luteinizing hormone LH, follicle stimulating hormone FSH and thyrotropin TSH were not altered significantly. In addition, in 5 acromegalic patients who were studied with both L-dopa and pyridoxine, inhibition of GH secretion followed either agent in a similar pattern. These data suggest a hypothalamic dopaminergic effect of pyridoxine.

Pyridoxine (B6) suppresses the rise in prolactin and increases the rise in growth hormone induced by exercise.
Moretti C, Fabbri A, Gnessi L, Bonifacio V, Fraioli F, Isidori A.
=====================================
Boll Soc Ital Biol Sper 1984 Feb 28;60(2):273-8
[Influence of administration of pyridoxine on circadian rhythm of plasma ACTH, cortisol prolactin and somatotropin in normal subjects]
[Article in Italian]
Barletta C, Sellini M, Bartoli A, Bigi C, Buzzetti R, Giovannini C.
The influence of vitamin B6 in a dosage of 300 mg X 2 in 24 hrs, on circadian rhythm of plasmatic ACTH, cortisol, prolactin and somatotropin have been studied in 10 normal women. After vitamin B6 24 hrs pattern of ACTH and cortisol is unchanged; prolactin levels are slightly lower, in a statistically unsignificant proportion the night peak of growth hormone is higher in a statistically significant proportion (p. 0.05). The effect of vitamin B6 is likely to me mediated by dopaminergic receptors at hypothalamic level as previous studies by other authors appear to prove.

Here is another one for B6.

Treatment of women with the galactorrhea-amenorrhea syndrome with pyridoxine (vitamin B6)
EN McIntosh
Three women with the galactorrhea-amenorrhea syndrome and elevated prolactin concentrations experienced a return of regular ovulatory menses within 37-94 days after starting pyridoxine treatment (200-600 mg/day). In each the galactorrhea ceased and serum prolactin levels were maintained in the normal range while taking pyridoxine. In two other women with prolonged secondary amenorrhea but without hyperprolactinemia or galactorrhea, pyridoxine at dosages up to 600 mg/day did not restore ovulatory menses. Pyridoxine treatment was also ineffective in decreasing profuse galactorrhea in one woman with normal prolactin levels and regular ovulatory menses. In the three women effectively treated with pyridoxine, the galactorrhea returned, serum prolactin levels increased, and the menses ceased after discontinuing pyridoxine. These results imply that pyridoxine, by decreasing the excessive secretion of prolactin, may be useful in the long-term medical management of women with hyperprolactinemia and the galactorrhea-amenorrhea syndrome.
