Summary of Interactions with Vitamins, Herbs, & Foods
Replenish Depleted Nutrients
- Vitamin D
Oral corticosteroids reduce absorption of calcium3 and interfere with the activation and metabolism of the vitamin,4 , 5 , 6 , 7 increasing the risk of bone loss. Doctors can measure levels of activated vitamin D (called 1,25 dihydroxycholecalciferol) to determine whether a deficiency exists; if so, activated vitamin D is only available by prescription. A study of rheumatoid arthritis patients treated with low amounts of prednisone found that those who received 1,000 mg of calcium per day plus 500 IU of vitamin D per day for two years experienced no bone loss during that time period.8 An analysis of properly conducted trials concluded that supplementation with vitamin D and calcium was more effective than placebo or calcium alone in protecting against corticosteroid-induced osteoporosis.9 Most doctors recommend 1,000 mg of calcium and 400–800 IU vitamin D per day for the prevention of osteoporosis.The interaction is supported by preliminary, weak, fragmentary, and/or contradictory scientific evidence.
Preliminary data suggest that corticosteroid treatment increases chromium loss.10 Double-blind trials are needed to confirm these observations.The interaction is supported by preliminary, weak, fragmentary, and/or contradictory scientific evidence.
A controlled trial found that a single dose of the synthetic corticosteroid dexamethasone suppressed production of melatonin in nine of 11 healthy volunteers.11 Further research is needed to determine if long-term use of corticosteroids interferes in a meaningful way with melatonin production, and whether supplemental melatonin would be advisable for people taking corticosteroids.The interaction is supported by preliminary, weak, fragmentary, and/or contradictory scientific evidence.
Oral corticosteroids increase the urinary loss of potassium.12 This may not cause a significant problem for most people. Individuals who wish to increase potassium intake should eat more fruits, vegetables, and juices rather than taking over-the-counter potassium supplements, which do not contain significant amounts of potassium.
Corticosteroids may increase the loss of vitamin B6.13 One double-blind study of people with asthma failed to show any added benefit from taking 300 mg per day of vitamin B6 along with inhaled steroids.14 Therefore, while small amounts of vitamin B6 may be needed to prevent deficiency, large amounts may not provide added benefit. Some doctors recommend that people taking corticosteroids for longer than two weeks supplement with at least 2 mg of vitamin B6 per day.
Reduce Side Effects
Preliminary data suggest that supplementation with chromium (600 mcg per day in the form of chromium picolinate) may prevent corticosteroid-induced diabetes.15 Double-blind trials are needed to confirm these observations.
Horny Goat Weed
According to preliminary human studies, horny goat weed offset some of the side effects of corticosteroids.16
When applied to the skin, glycyrrhetinic acid (a chemical found in licorice (Glycyrrhiza glabra)) increases the activity of hydrocortisone.17 This effect might allow for less hydrocortisone to be used when combined with glycyrrhetinic acid, but further study is needed to test this possibility.18
One preliminary study found that in people with fibrosing alveolitis (a rare lung disease), supplementation with 600 mg N-acetyl cysteine three times per day increased the effectiveness of prednisone therapy.21
Zinc and Biotin
Children with alopecia areata who supplemented 100 mg of zinc and 20 mg biotin each day, combined with topical clobetasol, showed more improvement compared to children who took oral corticosteroid drugs.22 Controlled research is needed to determine whether adding oral zinc and biotin to topical clobetasol therapy is more effective than clobetasol alone. However, until more information is available, caregivers should consider that children with alopecia who are currently taking oral corticosteroids might benefit from switching to supplements of zinc and biotin along with topical clobetasol.
Potential Negative Interaction
Oral corticosteroids cause both sodium and water retention.24 People taking corticosteroids should talk with their doctor about whether they should restrict salt intake.
Use of buckthorn (Rhamnus catartica, Rhamnus frangula, Frangula alnus) or alder buckthorn (Rhamnus catartica, Rhamnus frangula), for more than ten days consecutively may cause a loss of electrolytes (especially the mineral potassium). Because corticosteroids also cause potassium loss, buckthorn or alder buckthorn should be used with caution if corticosteroids are being taken.25
In animal research, applying aloe (Aloe vera) gel topically along with a topical corticosteroid enhanced the hormone’s anti-inflammatory activity in the skin.26 No human research has investigated this effect.
Use of buckthorn (Rhamnus catartica, Rhamnus frangula, Frangula alnus) or alder buckthorn (Rhamnus catartica, Rhamnus frangula), for more than ten days consecutively may cause a loss of electrolytes (especially the mineral potassium). Because corticosteroids also cause potassium loss, buckthorn or alder buckthorn should be used with caution if corticosteroids are being taken.28
Taking the oral corticosteroid methylprednisolone with grapefruit juice has been shown to delay the absorption and increase the blood concentration of the drug.29 The mechanism by which grapefruit juice increases the concentration of methylpredniolone in the blood is not known, but it is suspected that it may interfere with enzymes in the liver responsible for clearing the drug from the body. In certain people, grapefruit juice may, therefore, enhance the effects of methylprednisolone. The combination should be avoided unless approved by the prescribing doctor.
Licorice (Glycyrrhiza glabra) extract was shown to decrease the elimination of prednisone in test tube studies.30 If this action happens in people, it might prolong prednisone activity and possibly increase prednisone-related side effects. A small, controlled study found that intravenous (iv) glycyrrhizin (an active constituent in licorice) given with iv prednisolone prolonged prednisolone action in healthy men.31 Whether this effect would occur with oral corticosteroids and licorice supplements is unknown.
An animal study has shown that glycyrrhizin prevents the immune-suppressing actions of cortisone—the natural corticosteroid hormone produced by the body.32 More research is necessary to determine if this action is significant in humans taking oral corticosteroids. Until more is known, people should not take licorice with corticosteroids without first consulting a doctor.
Corticosteroids may increase the body’s loss of magnesium.33 Some doctors recommend that people taking corticosteroids for more than two weeks supplement with 300–400 mg of magnesium per day. Magnesium has also been reported to interfere with the absorption of dexamethasone.34
Pomegranate juice has been shown to inhibit the same enzyme that is inhibited by grapefruit juice.35 The degree of inhibition is about the same for each of these juices. Therefore, it would be reasonable to expect that pomegranate juice might interact with oral corticosteroids in the same way that grapefruit juice does.
Oral corticosteroids have been found to increase urinary loss of selenium.36 , 37 The importance of these losses is unknown.
In some people, treatment with corticosteroids can impair wound healing. In one study, topical or internal vitamin A improved wound healing in eight of ten patients on corticosteroid therapy.38 In theory, vitamin A might also reverse some of the beneficial effects of corticosteroids, but this idea has not been investigated and no reports exist of such an interaction in people taking both vitamin A and corticosteroids. People using oral corticosteroids should consult with a doctor to determine whether improved wound healing might outweigh the theoretical risk associated with concomitant vitamin A use.
Although blood levels of vitamin A appear to increase during dexamethasone therapy39—most likely due to mobilization of the vitamin from its stores in the liver—evidence from animal studies has also indicated that corticosteroids can deplete vitamin A from tissues.40
