Hi Deva,
As you are new to CML and asking for suggestions. I recommend you read a few things first to get you oriented.
You'll meet Trey soon enough who will comment directly. He has written a pretty good summary of CML information for people new to CML. Start there:

Another very good reference are the actual guidelines doctors are encouraged to follow during the course of your treatment:

Throughout your journey and as you read and write on this forum, you will find many opinions on what to do, what not to do as you decide on your treatment plan. One size does not fit all. Many of us have unique responses that do require tweaking of dose, drug or other options. As you read, you may find you fit in with one or more other patients who have similar history to you. They can be a good resource as well.
Regarding vitamins - where much debate does occur - I have found that TKI's do deplete the body of some minerals. In particular, magnesium. To help with cramps its recommended you take at least 400mg magnesium per day (I take Magnesium taurate) split in two doses - morning and just before bedtime. I do not take calcium as food contains plenty of calcium in our diet typically. I do take vitamin D3 in order to keep my vitamin D level above 50 and below 80 ng/ml. It's important to have your vitamin D level checked before supplementing too much. I take vitamin K2 (200 mcg) which works with vitamin D.
Read, learn, participate and you will find the fear of CML begin to fade. You will be fine. CML is the one cancer that is being beaten by innovation in treatment. Also - go ahead and add a "signature" line to your profile detailing your diagnosis, TKI and treatment milestones (see mine below). It's good way for others commenting on your questions to know your history as you proceed.
