I Am A Very Healthy Eater So I Was Surprised

I am a very healthy eater so I was surprised when my doctor said my cholesterol was high at 230. It made sense when we found out that my vitamin D was very low since i don't get enough sun. My doctor just subscribed Vitamin D pills and Simvastatin 10 mg for me. I see that Simvastatin has a lot of side effects. Is there an alternative med i she can subscribe?
