Supplements For Cancer Prevention

Supplements For Cancer Presentation

For most of us the transitioning to a healthy, wholesome, cancer-preventing diet will probably take some time.

During that transition, there are certain natural supplements that can be helpful in supporting our body’s innate cancer-fighting mechanisms. While these supplements are generally considered safe at the therapeutic dose, it would always be wise to double check with a licensed health care provider like a naturopath for personalized dosing.

Top 4 Supplements For Cancer Prevention

Green tea extract

It is very likely that you’ve heard of the health benefits of green tea. It is rich in polyphenols and other compounds, such as EGCG, which have been shown to have good benefits for a whole host of conditions, such as cardiovascular disease.

In the cancer realm, green tea is associated with a reduced risk for ovarian, cervical, endometrial, and breast cancers. More and more evidence accumulates on its benefit for all other cancers.

Green tea not only prevents cancer indirectly as an antioxidant but also actively prevents the initiation and progression of cancer. It can also be successfully used as an adjuvant to chemotherapy and radiation.

The only potential downside to drinking green tea is that you have to drink quite a bit every day to reap all its benefits, and if you’re avoiding caffeine, that could be a problem.

This is where a caffeine-free green tea supplement can really come in handy. Look for formulas standardized to catechins and EGCG, and those that are labeled caffeine-free.


Indole-3-cabinol (I3C) is found mostly in the plants of the Cruciferous family, which include cabbage, broccoli, cauliflower, kale, turnips, etc.

I always say that the best way to get this nutrient is through a diet very rich in vegetables including the cruciferous veggies.

While you work your way towards achieving that rich green diet, consider supplementing I3C or its metabolite DIM in the interim.  

Studies are demonstrating that I3C shifts the metabolism of estrogen down a safer, less cancer-prone pathway. It also supports the liver’s detoxification function, which as you already know, keeps the body clean and  healthy.

Be mindful, however, that raw Cruciferous vegetables may exacerbate thyroid conditions, so if you have issues with your thyroid, make sure that most of your Cruciferous veg is cooked.

Vitamin D

Too many people nowadays are deficient in vitamin D, because it is mired in a lot of paradoxes.

Those with darker skin are more protected from the sun’s harmful radiation, but that also means they can’t produce a lot of vitamin D in their skin.

Those with fair skin are able to produce adequate vitamin D when exposed to the sun, but they are more likely to damage to their skin and put themselves at risk for skin cancer.

The further anyone lives from the equator, the less sun they get throughout the year, reducing their vitamin D producing capacity.

Cancer Preventing Supplements

Supplementing vitamin D becomes a great option to make sure your body is not low on this crucial vitamin. Vitamin D has been shown to prevent unwanted cell proliferation, promote cancer cell death, suppress inflammation and even regulate immune cells.

Keep in mind that vitamin D is a fat-soluble vitamin, which means it can easily accumulate in the body when taking very high doses. Talk to your doctor or naturopath about dosing.


Turmeric is the latest and greatest superfood.

This common spice in south Asian cuisine is raking in the scientific studies on its anti-inflammatory effects. As previously explained, uncontrolled inflammation is the body’s enemy when it comes to wellbeing and cancer risk.

As a potent and safe inflammation fighter, turmeric can really help bring the immune system back in line in inflammatory diseases, but it can also directly prevent the formation and proliferation of cancer cells.

If you are comfortable including turmeric in your daily diet, go for it. If you are weary yet, there are supplements that concentrate the active component (curcumin) into capsules. Look for formulations that include a bit of black pepper to improve absorption.
