Vitamin K (total)
Needed for blood clotting and for directing calcium into bone rather than soft tissue.
Trimester focus
| Stage | For the mother | For the baby |
|---|---|---|
| First trimester | Supports normal maternal clotting function. | Crosses the placenta only in small amounts; newborn stores start low. |
| Second trimester | Continues supporting clotting and bone-protein activation. | Supports early skeletal-protein (osteocalcin) activation. |
| Third trimester | Helps route the calcium being transferred to the fetus into bone. | Activates bone proteins as skeletal mineralisation accelerates. |
Target note
