Hello and thanks for posting

I am sorry to hear about your friend needing chemo but it is good to hear they are doing well after surgery.

When it comes to preparing for chemotherapy it sounds like your friend is already on the right track with eating sensible ( a balanced and healthy diet) avoiding alcohol and not smoking. If they also carry out some regular light exercise as well this also can be useful. We have some information about preparing for treatment physically here and eating here.

As long as patients are eating healthily they should get all the nutrients they need from their food without the need for supplements. Patients undergoing cancer treatments need to check with their own doctor if they are taking or wish to take additional supplements as some may interfere with the treatment. There is more information at this link.

I wish your friend all the best moving forward but do get back if you have more questions.

Take care

Naomi
