Why this happens
Simvastatin is a cholesterol-lowering medication (statin) processed primarily by the liver, while vitamin B12 is a water-soluble vitamin absorbed in the gut and used for nerve and blood health. They do not interfere with each other's absorption, metabolism, or effectiveness.
What you should do
You can continue taking both as prescribed. You do not need to separate the doses or change the time of day you take them. Always inform your doctor or pharmacist of all supplements you are taking.
