Summary of Interactions with Vitamins, Herbs, & Foods

Types of interactions: Beneficial Adverse Check

Replenish Depleted Nutrients

  • Potassium-depleting diuretics, including loop diuretics, cause the body to lose potassium. Loop diuretics may also cause cellular magnesium depletion, although this deficiency may not be reflected by a low blood level of magnesium. Magnesium loss induced by potassium-depleting diuretics can cause additional potassium loss. Until more is known, it has been suggested that people taking potassium-depleting diuretics, including loop diuretics, should supplement both potassium and magnesium.

    People taking loop diuretics should be monitored by their doctor, who will prescribe potassium supplements if needed. Such supplementation is particularly critical before surgery in patients with a history of heart disease. In a preliminary study, people with low blood levels of potassium (in part related to diuretic use) had a higher incidence of serious problems resulting from surgery (including death) compared with those having normal potassium levels. Fruit is high in potassium, and increasing fruit intake is another way of supplementing potassium. Magnesium supplementation is typically 300–400 mg per day.

  • Folic Acid

    One study showed that people taking diuretics for more than six months had dramatically lower blood levels of folic acid and higher levels of homocysteine compared with individuals not taking diuretics. Homocysteine, a toxic amino acid byproduct, has been associated with atherosclerosis. Until further information is available, people taking diuretics for longer than six months should probably supplement with folic acid.

    The interaction is supported by preliminary, weak, fragmentary, and/or contradictory scientific evidence.
  • Vitamin B1

    People with congestive heart failure (CHF) treated with the loop diuretic furosemide may be at risk for vitamin B1 deficiency due to: 1) the disease, 2) treatment with furosemide, and/or 3) inadequate dietary vitamin B1 intake. In a study of people with CHF, long-term furosemide therapy was associated with clinically significant vitamin B1 deficiency due to urinary losses. This furosemide-induced vitamin B1 deficiency may worsen heart function in patients with CHF and may be prevented or corrected with vitamin B1 supplementation.

Potential Negative Interaction

  • Dandelion
    Herbs that have a diuretic effect should be avoided when taking diuretic medications, as they may increase the effect of these drugs and lead to possible cardiovascular side effects. These herbs include dandelion, uva ursi, juniper, buchu, cleavers, horsetail, and gravel root.
  • Digitalis (Digitalis purpurea) refers to a family of plants commonly called foxglove that contain digitalis glycosides, chemicals with actions and toxicities similar to the prescription drug digoxin. Loop diuretics can increase the risk of digitalis-induced heart disturbances. Loop diuretics and digitalis-containing products should only be used under the direct supervision of a doctor trained in their use.

  • Herbs that have a diuretic effect should be avoided when taking diuretic medications, as they may enhance the effect of these drugs and lead to possible cardiovascular side effects. These herbs include dandelion, uva ursi, juniper, buchu, cleavers, horsetail, and gravel root.

    Use buckthorn (Rhamnus catartica, Rhamnus frangula, Frangula alnus) or alder buckthorn for more than ten days consecutively may cause a loss of electrolytes (especially the mineral potassium). Medications that also cause potassium loss, such as some diuretics, should be used with caution when taking buckthorn or alder buckthorn.

Explanation Required 

  • Licorice

    Licorice (Glycyrrhiza glabra) may enhance the side effects of potassium-depleting diuretics, including loop diuretics. Loop diuretics and licorice should be used together only under careful medical supervision. Deglycyrrhizinated licorice (DGL) may be used safely with all diuretics.

    The interaction is supported by preliminary, weak, fragmentary, and/or contradictory scientific evidence.
  • Diuretics, including loop diuretics, cause increased loss of sodium in the urine. By removing sodium from the body, diuretics also cause water to leave the body. This reduction of body water is the purpose of taking diuretics. Therefore, there is usually no reason to replace lost sodium, although strict limitation of salt intake in combination with the actions of diuretics can sometimes cause excessive sodium depletion. On the other hand, people who restrict sodium intake and in the process reduce blood pressure may need to have their dose of diuretics lowered.

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