We observed an interesting case involving a 1-month-old infant with significant bruising and severe vitamin K deficiency. This deficiency led to spontaneous thymic hemorrhage, which was identified along with coagulopathy during medical evaluation.
The child had not received vitamin K prophylaxis at birth, which likely contributed to the outcomes we saw. Fortunately, after administering vitamin K, the coagulopathy improved. This case highlights the essential role of vitamin K in preventing serious bleeding issues in infants.

Vitamin K improves coagulation and bruising
The report focused on a 4-year-old girl suffering from spontaneous bruising due to vitamin K deficiency linked to celiac disease. After receiving intravenous vitamin K for three days, her coagulation tests returned to normal, and the bruising began to fade.
This treatment was essential alongside her gluten-free diet, which helped in her full recovery. The study illustrates the significant role vitamin K plays in managing bruising, particularly in patients with conditions that affect its absorption.

Vitamin K gel accelerates bruise resolution
We conducted a well-structured study to evaluate the effectiveness of a topical vitamin K oxide gel in speeding up the healing of facial bruises caused by cosmetic laser treatments. In our double-blinded, placebo-controlled study, twenty volunteers applied either the vitamin K gel or a placebo on each side of their face for nine days.
The results showed that the vitamin K gel did help speed up the resolution of bruising compared to the placebo. This suggests it could be beneficial not just for laser-induced bruises, but also for other cosmetic procedures.

Good purchase! A great vitamin to take if you bruise easily. Just be advised that it is recommended to take a calcium vitamin alongside the K2.

Minimized bruise severity

I ran into a wall and expected a large bruise on my upper arm, but the bruising was minimal. After consulting my doctor, we think it’s due to the addition of K2 to my daily supplement regimen.

We set out to understand how vitamin K1 could impact healing on full-thickness wounds in rats. Using a model that created such wounds, we applied vitamin K cream in different concentrations daily. The results were promising: wounds treated with vitamin K showed significant improvements in healing, including faster contraction and better skin re-growth compared to a control group. This suggests that vitamin K could be beneficial for wound healing, although further research is needed to confirm its effectiveness in humans.

Improved outcomes with ABC pathway
We examined the Atrial Fibrillation Better Care (ABC) pathway in a cohort of patients in Iran. Over the study's duration, adherence to the ABC strategy improved management significantly.
Notably, the incidence of skin bruising dropped from 1.2% to 0% after implementing the pathway. This indicates a positive impact on patient outcomes, including fewer strokes and heart failure instances, highlighting the ABC pathway's potential effectiveness in managing atrial fibrillation.
