Vitamin C: Oral Use

Vitamin C, available in several foods and dietary supplements, shows some anticancer effects, including better survival among people with breast cancer.

.

Vitamin C: Intravenous Use

Vitamin C can be given intravenously to achieve much higher blood levels and enhance its antioxidant and anti-inflammatory effects, with limited evidence of improved cancer survival when used with conventional treatments.

.

Time in Nature or Forest Bathing

Simply spending time in nature shows benefits both for body terrain factors linked to cancer and for reducing cancer risk. It may also help with symptoms common among people with cancer.

.

Resveratrol

Resveratrol is a natural antioxidant compound found in grape skins and other foods and widely available as a supplement. It is linked to body terrain that is less favorable to cancer growth and spread.

.

Melatonin

Melatonin supplements mimic the effects of your own naturally produced melatonin in promoting sleep, and research shows melatonin can have a substantial role in cancer outcomes and side effects.

.

Iodine

As an essential nutrient, iodine is needed for thyroid function, and a deficiency is linked to higher risk of thyroid and stomach cancers. Some evidence shows that treatment with molecular iodine before breast cancer surgery may improve tumor response and reduce some side effects.

.

Green Tea or EGCG

Green tea and its extracts may provide substantial benefit for body terrain factors, especially body weight, high blood sugar and insulin resistance, inflammation, oxidative stress, each of which is linked to cancer development and growth.

.

Fasting or Calorie Restriction

Calorie restriction and fasting, whether for 12 or more hours every night or occasionally for longer periods, can contribute to lower body weight, blood sugar, and insulin resistance, plus fewer unpleasant chemotherapy-related side effects.

.

Berberine

Berberine, an active ingredient in several plants, shows good effects in managing high blood sugar and excess body weight, plus lower risk of colorectal cancer.

.

Aspirin

Aspirin is a widely available over-the-counter medication that shows substantial effects at promoting survival and reducing risk of many types of cancer, plus reducing inflammation and managing pain due to inflammation.
