Vitamin K2 drops could shield breastfed infants from bleeding risk
NCT ID NCT07620236
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 2 times
Summary
This study tests whether giving vitamin K2 (MK-7) supplements to breastfed infants or their breastfeeding mothers can prevent vitamin K deficiency at 2 months of age. About 134 healthy, full-term babies who received standard vitamin K shots at birth will be enrolled. Some infants will get MK-7 drops, others a placebo, and some mothers will take MK-7 capsules. The goal is to see if extra vitamin K2 improves blood markers of vitamin K status and reduces the risk of rare but serious bleeding.

Active substance
Vitamin K2 (menaquinone-7; MK-7) drops or capsules, with or without vitamin D3
What this could lead to
If it works, this could point toward a simple daily supplement to prevent vitamin K deficiency and related bleeding in breastfed babies.
What could go wrong
This is an early, small study (134 infants) that has not yet started recruiting. It may not show a clear benefit, and results may not apply to all infants.
