  • Iron

  • Potassium

Bone health is too often over-looked by Oncologists, when it should be an essential component of the treatment care plan for ALL people with cancer.

Please talk to your doctor about whether or not you should be taking a Calcium or Vitamin D supplement.

Another easy way to get Vitamin D is from direct sunlight. 

Aim to get 10-30 minutes of sun several times a week, but safely of course, wearing a sunscreen with an SPF of 50 or more.
