Summary of
Interactions with Vitamins, Herbs, and Foods
In some cases, a herb or supplement may appear in more than one category, which may seem
contradictory. For clarification, read the full article for details about the summarized
interactions.
May be Beneficial: Depletion or
interference—The medication may deplete or interfere with the absorption or
function of the nutrient. Taking these nutrients may help replenish them. |
Riboflavin*

May be Beneficial: Side effect
reduction/prevention—Taking these supplements may help reduce the likelihood and/or
severity of a potential side effect caused by the medication. |
Carnitine*

May be Beneficial: Supportive
interaction—Taking these supplements may support or otherwise help your medication
work better. |

Interactions with Dietary Supplements
Carnitine
Animal research suggests carnitine may prevent doxorubicin’s toxicity.1
Coenzyme
Q10
Pretreating people with the antioxidant
coenzyme Q10 before administration of doxorubicin has reduced cardiac toxicity2
—an action also reported in animals.3 Some doctors recommend 100 mg per
day.
Melatonin
Melatonin supplementation (20 mg per day) has decreased toxicity and improved effectiveness of
chemotherapy with doxorubicin.4
N-acetyl cysteine
(NAC)
The antioxidant supplement N-acetyl cysteine (NAC) has protected animals from the
cardiotoxicity of doxorubicin,5 although human research has not been able to
confirm these results.6 Most doctors do not yet suggest NAC for people taking
doxorubicin.
Riboflavin
Animal research suggests doxorubicin may deplete riboflavin and that riboflavin deficiency
promotes doxorubicin toxicity.7
Vitamin
C
The antioxidant vitamin C has protected against cardiotoxicity (damage to the heart) of
doxorubicin in an animal study.8 In this trial, vitamin C significantly increased
the life expectancy of mice and guinea pigs without interfering with anticancer action of the
drug. Despite the lack of human data, some doctors recommend that patients taking doxorubicin
supplement at least 1 gram of vitamin C per day.
Vitamin
E
Animal studies show that the antioxidant
activity of vitamin E protects against doxorubicin-induced cardiotoxicity.9
10 Test tube evidence suggests that vitamin E might also enhance the anticancer action
of the drug.11 Human trials exploring the cardioprotective action of vitamin E in
people taking doxorubicin remain inconclusive; however, some evidence suggests that vitamin E
may allow for higher drug doses without increasing toxicity.12
Anecdotal reports indicate that very high (1,600 IU) amounts of vitamin E may reduce the
amount of hair loss accompanying use of doxorubicin.13 However, while protection
against hair loss was confirmed in a rabbit study, human research has not found this to be
true.14
