Bolisetty [63] | 2.5 mg phylloquinone (vitamin K1) orally daily for 2 weeks | Six healthy lactating mothers who gave birth to preterm infants at a median post conceptional age of 29.5 (range 26–30) weeks. | Randomized clinical trial | To raise the vitamin K content in the breast milk to levels recommended for infant formulae by RDA and to look at day-to-day variation in the breast milk vitamin K levels with maternal supplementation of vitamin K. | phylloquinone vitamin K1 | Phylloquinone levels in the breastmilk increased from a baseline of 3 ± 2.3 ng ml− 1 to 22.6 ± 16.3 ng ml− 1 (mean ± SD) after the first dose (p < 0.05); a gradual increase was noted until phylloquinone levels reached a plateau of 64.2 ± 31.4 ng ml− 1 after the sixth daily dose. |

Greer [65] | Ten mothers received 2.5 mg/d oral phylloquinone, and 10 mothers received 5.0 mg/d oral phylloquinone. | Twenty exclusive breastfeeding mothers. | longitudinal, randomized, double-blind, placebo-controlled |
To increase the phylloquinone (Vitamin K1) concentration of human milk with maternal oral phylloquinone supplements. |
Phylloquinone | Both 2.5 and 5.0 mg/d phylloquinone significantly increased the phylloquinone content of human milk at both 2 and 6 weeks. As expected, 5.0 mg had a greater effect. |

Kries [66] | Vitamin K1 | Nine mothers (age of the mothers ranged between 17 and 34 yr, mean 24 yr) | Randomized clinical trial | To assess the effect of Vitamin KI Supplements on maternal milk. | Vitamin K1 | To test the influence of diet, mothers were given oral supplements of vitamin K I. Doses of 0.5–3 mg produced substantial rises in breast milk vitamin K I with peak levels between 12 and 24 h. In one mother in whom the milk sampling was standardized, a dose-response relationship was observed. |
