Vitamin K3

CAS #58-27-5

Vitamin K3, also known as menadione, is a synthetic supplement that acts as a precursor for vitamin K2



Vitamin K3, also known as menadione, is a synthetic supplement that acts as a precursor for vitamin K2, the most useful form of vitamin K for the human body. Since menadione does contain some vitamin K activity, it is commonly placed in livestock feed and some pet food to increase nutrient content. The use of vitamin K3 supplements in most developed countries is banned due to its possible side effects, such as damage to internal organs like kidneys or liver. Research on vitamin K3 has shown that it has some effect in combating certain types of cancer, yet research in regards to human safety remains inconclusive.
