and Cancer

What you should know.

There is a difference between consuming antioxidants from

food and antioxidants from supplements.


PLEASE NOTE: antioxidant supplements should not be taken while you’re undergoing cancer treatment.  Some of them are so powerful that they can decrease the effects of your treatment, meaning the treatment won’t work as well.

For example, some antioxidant supplements, such as Vitamins C and E, can cause skin sensitivity and severe reactions when taken during radiotherapy treatment.  They can also interfere with how well chemo drugs work.  Co enzyme Q10, selenium and vitamins A, C and E can also interfere with chemotherapy and prevent the cancer cell damage that it's aiming for. 

Many doctors will advise you to stay away from all supplements and vitamins while you’re on treatment unless, for example you have a Calcium deficiency, then your doctor will advise you keep taking Calcium and Vitamin D supplements. 

There is no reliable evidence that any dietary supplement can help to prevent cancer. But there is evidence that a healthy diet with a variety of whole foods (fruits, vegetables, whole grains, poultry, and fish) can reduce your cancer risk.  Your body absorbs more nutrients from food than it does from most supplements. 

Once you’ve finished cancer treatment and have been given the go ahead from your doctor to resume taking them, certain supplements can be beneficial especially if they’re missing from your diet.  For example, the following supplements have cancer fighting properties, but can also be difficult to incorporate into your diet if you’re not used to them: 

~ Ground flax seed

~ Turmeric

~ Ginger

~ Garlic

Other popular supplements after cancer treatment are:

~ Selenium

~ Glutathione

~ Omega 3 FAs

~ Vitamin C

~ Green tea

~ Vitamin D  

~ Vitamin E

Several studies have shown that these vitamins or minerals can help to reduce certain types of cancer.  They can also be obtained through eating a balanced diet, but may be worth supplementing under the advise of your Physician.


Even if you are finished treatment, please consult your doctor before taking any Vitamins of supplements.
