Can I take Simvastatin and Vitamin d together?

Why this happens

Vitamin D and simvastatin are both processed by the same enzyme in the liver (CYP3A4). High doses of vitamin D might speed up this enzyme, causing the body to break down simvastatin a bit faster than usual. Conversely, some studies suggest vitamin D helps prevent the muscle aches sometimes caused by statins.

What you should do

You can safely take these together. You do not need to change your dose, but it is always good practice to inform your doctor or pharmacist about any supplements you are taking. If you notice your cholesterol levels rising or experience unusual muscle pain, speak with your GP.
