No, vitamin D is not a mouse poison, warfarin is a mouse poison, also known as coumadin, often used in rehab hospitals, warfarin is known to interfere with vitamin K1 function, Vitamin k1 is the greens vitamin needed for the proper functioning of platelets and clotting.
Vitamin K1 is converted to vitamin K2 in grass fed milk and meat and eggs, and is valuable for tooth repair and development and skeletal development- and making sure vitamin D works as a team with calcium (along with A, and magnesium) as it guides calcium to bones and ensures proper functions as it pulls it out of soft tissues like arteries and nerves and improper places.
K2 prevents heart disease. K2 could safely be used instead of warfarin in knee and hip replacement patients.
