Vitamin K is essential for blood clotting and wounds to heal properly.
The Danish biochemist Henrik Dam, discovered this vitamin in 1935 and named it K for koagulation (Danish word for coagulation). Here we will see how vitamin K helps in the healing process, how much is necessary and how to obtain it.
As with any other vitamin, our body needs K to be healthy and function properly.
Its main benefits include maintaining bone health, activating proteins, providing protection against different diseases (including cancer), and reducing the risk of premature death.
Vitamin K is also strongly linked to the circulatory system and has been shown to help prevent bleeding that can lead to bruising, a swelling that hinders the healing process and favors infection or opening of the wound.
For decades, experts have studied the healing effects of vitamin K. For example, an article published in Nature in 1960 he highlighted “the pronounced effect of vitamin K in accelerating the rate of bone healing.”
Recently, a group of experts published in Indian Journal of Pharmacology a clinical trial analyzing the effects of topical use of vitamin K on skin wounds.

To do this, they divided 63 patients into three groups, who underwent treatment with high-frequency electrocautery (a method of cauterizing and sealing blood vessels).
Each group then received a different supplement or medication: the first 1% vitamin K cream, the second 1% phenytoin cream (anticonvulsant), and the control group Eucerin (a type of lotion for sensitive skin).
The condition of the wound (width and recovery time) and complications in the three groups were evaluated by a dermatologist 2 weeks after the procedure.
The experts stated that the group treated with the vitamin K cream showed significant scarring compared to the Eucerin group.
Due to its coagulant properties, vitamin K promotes wound contraction and accelerates recovery time.
According to the authors of the work, their findings show that “the topical application of vitamin K significantly reduces the healing time in patients.”
