Vitamin-K1 capsules are fat-soluble vitamins for optimum health. A K deficiency can lead to a bleeding disorder. These tablets contain the same type and degree of activity as naturally-occurring vitamin K. Customers may receive this drug under the name Phytonadione.

Proudly sourced directly from the manufacturer or their approved distributor. Guaranteed genuine and backed by the manufacturer.


Vitamin K1 is used as a blood thickening agent.

Possible Side Effects

Brief flushing sensations and peculiar sensations of taste have been observed with parenteral phytonadione, as well as rare instances of dizziness, rapid and weak pulse, profuse sweating, brief hypotension, dyspnea and cyanosis.

Drug & Food Interactions

Notify your veterinarian of any other medications, including vitamins and supplements, your pet is taking before using this vitamin.


Protect from light at all times. Temporary resistance to prothrombin-depressing anticoagulants may result, especially when larger doses of phytonadione are used.
