Vitamin K is probably not a very well known vitamin, but in many countries, a newborn baby will be given this right after birth to prevent bleeding problems. This vitamin plays an important role in the clotting of blood as well as the metabolism of bone.
Vitamin K can also be applied topically to help with scars, veins, stretch marks and burns.
A deficiency of vitamin K is rare and when it happens its most likely to happen to infants – hence the vaccine is given after birth. A deficiency in the vitamin is likely to lead to bleeding problems both internally and externally.
