What is K 100?
K 100 is a dietary supplement taken to address vitamin K deficiency. Each tablet contains 100 mcg of vitamin K1.
All the K vitamins take part in a chain of reactions that cause blood to clot, so a vitamin K deficiency leads to problems with bleeding and bruising.
Vitamin K1, also called phytonadione, phytomenadione, or phylloquinone, is plentifully available in foods such as green vegetables. Vitamin K deficiency is usually caused by drugs, such as aspirin or antibiotics, that interfere with the body's ability to use vitamin K.
K 100 is taken as a tablet.
What are the side effects of K 100?
K 100 has minimal side effects that are only rarely experienced. While not a complete list, the most common side effects of K 100 are a blue color on the lips, fingernails, or palms, changes in taste, increased sweating, shortness of breath, flushing, and dizziness. Allergic reactions are rare and usually due to the inactive ingredients in K 100.
