Summary of Interactions with Vitamins, Herbs, & Foods

Types of interactions: Beneficial Adverse Check

Replenish Depleted Nutrients

Reduce Side Effects

  • Fruit-Flavored Drinks

    Often, people who undergo chemotherapy develop aversions to certain foods, sometimes making it permanently difficult to eat those foods. Exposing people to what researchers have called a “scapegoat stimulus” just before the administration of chemotherapy can direct the food aversion to the “scapegoat” food instead of more important parts of the diet. In one trial, fruit drinks administered just before chemotherapy were most effective in protecting against aversions to other foods.1

  • Ginger

    Ginger (Zingiber officinale) can be helpful in alleviating nausea and vomiting caused by chemotherapy.2 , 3 Ginger, as tablets, capsules, or liquid herbal extracts, can be taken in 500 mg amounts every two or three hours, for a total of 1 gram per day.

  • Melatonin

    In preliminary research, large amounts of melatonin were used successfully in combination with tamoxifen in a few people with breast cancer for whom tamoxifen had previously failed.4 The amounts used in this study should be taken only under the supervision of a doctor.

  • Chamomile

    A liquid preparation of German chamomile (Matricaria recutita) has been shown to reduce the incidence of mouth sores in people receiving radiation and systemic chemotherapy treatment in an uncontrolled study. 5

    The interaction is supported by preliminary, weak, fragmentary, and/or contradictory scientific evidence.
  • Eleuthero

    Russian research has looked at using eleuthero (Eleutherococcus senticosus) with chemotherapy. One study of patients with melanoma found that chemotherapy was less toxic when eleuthero was given simultaneously. Similarly, women with inoperable breast cancer given eleuthero were reported to tolerate more chemotherapy.6 Eleuthero treatment was also associated with improved immune function in women with breast cancer treated with chemotherapy and radiation.7

    The interaction is supported by preliminary, weak, fragmentary, and/or contradictory scientific evidence.

Support Medicine

  • Melatonin

    In preliminary research, large amounts of melatonin were used successfully in combination with tamoxifen in a few people with breast cancer for whom tamoxifen had previously failed.8 The amounts used in this study should be taken only under the supervision of a doctor.

  • Gamma Linolenic Acid

    Gamma-linolenic acid (GLA), found in evening primrose and borage oils, may enhance the therapeutic effects of tamoxifen. A small group of breast cancer patients took 2.8 g of oral GLA per day in addition to tamoxifen, in a preliminary trial.9 Another group of breast cancer patients took tamoxifen alone. Those taking the GLA-tamoxifen combination appeared to have a better clinical response than did those taking tamoxifen alone. However, the results of this preliminary research are far from conclusive and need to be confirmed in a larger, more definitive trial.

    The interaction is supported by preliminary, weak, fragmentary, and/or contradictory scientific evidence.
  • Milk Thistle

    Milk thistle’s (Silybum marianum) major flavonoids, known collectively as silymarin, have shown synergistic actions with the chemotherapy drugs cisplatin and doxorubicin (Adriamycin) in test tubes.10 Silymarin also offsets the kidney toxicity of cisplatin in animals.11 Silymarin has not yet been studied in humans treated with cisplatin. There is some evidence that silymarin may not interfere with some chemotherapy in humans with cancer.12

    The interaction is supported by preliminary, weak, fragmentary, and/or contradictory scientific evidence.
  • PSK

    The mushroom Coriolus versicolor contains an immune-stimulating substance called polysaccharide krestin, or PSK. PSK has been shown in several studies to help cancer patients undergoing chemotherapy. One study involved women with estrogen receptor-negative breast cancer. PSK combined with chemotherapy significantly prolonged survival time compared with chemotherapy alone.13 Another study followed women with breast cancer who were given chemotherapy with or without PSK. The PSK-plus-chemotherapy group had a 25% better chance of survival after ten years compared with those taking chemotherapy without PSK.14 Another study investigated people who had surgically removed colon cancer. They were given chemotherapy with or without PSK. Those given PSK had a longer disease-free period and longer survival time.15 Three grams of PSK were taken orally each day in these studies.

    Although PSK is rarely available in the United States, hot-water extract products made from Coriolus versicolor mushrooms are available. These products may have activity related to that of PSK, but their use with chemotherapy has not been studied.

    The interaction is supported by preliminary, weak, fragmentary, and/or contradictory scientific evidence.
  • Tocotrienols

    Tocotrienols are compounds similar to vitamin E that are found in palm oil. Test tube studies have shown that tocotrienols enhance the effects of tamoxifen.16 Controlled studies are needed to determine whether supplementing with tocotrienols might enhance the anticancer effects of tamoxifen.

    The interaction is supported by preliminary, weak, fragmentary, and/or contradictory scientific evidence.

Reduces Effectiveness

  • Tangeretin

    Preliminary research in animals found that the citrus flavonoid tangeretin (found primarily in the peel of citrus fruits) interferes with the ability of tamoxifen to inhibit tumor growth.17 Although the evidence is far from conclusive, people taking tamoxifen should probably avoid citrus bioflavonoid supplements, as well as beverages and foods to which citrus peel oils have been added.

    The interaction is supported by preliminary, weak, fragmentary, and/or contradictory scientific evidence.

Potential Negative Interaction

  • none

Explanation Required 

  • none

The Drug-Nutrient Interactions table may not include every possible interaction. Taking medicines with meals, on an empty stomach, or with alcohol may influence their effects. For details, refer to the manufacturers’ package information as these are not covered in this table. If you take medications, always discuss the potential risks and benefits of adding a new supplement with your doctor or pharmacist.
