Molybdenum + Losartan Potassium

No Known Interaction
Medically reviewed by · Updated July 2026 · Pair last verified Sep 13, 2026
The bottom line No known interaction

We found no known interaction between Molybdenum and Losartan Potassium in our sources. Absence of a documented interaction is not the same as proven safety, and does not guarantee one does not exist. Do not start, stop, or change a medication or supplement based on this page; confirm with your pharmacist or doctor first. Additionally, although there is no interaction, the two are separately associated with some of the same side effects, which would make a new symptom harder to attribute to one or the other.

Interaction report

Molybdenum and Losartan Potassium

We checked these two against our interaction database. Here is what we found.

No Known Interaction Found

We did not find a documented interaction between Losartan Potassium and Molybdenum in our sources. This does not guarantee that the combination is completely free of risk — there is often limited research on supplements and herbal products, especially around drug interactions.

Worth understanding: our licensed dataset holds no drug-interaction record for Molybdenum at all — not against Losartan Potassium, and not against any other medication we track. This verdict therefore rests on the absence of any recorded data, not on research that looked at this combination and found nothing. We cannot rule an interaction out.

If you decide to take both, the practical routine is simple: add one new thing at a time and note the date you started it. If the combination is going to disagree with you, it usually shows in the first days to a couple of weeks — and a start date turns “I’ve been feeling off” into something a pharmacist can actually work with. Do not stop a prescribed medicine on your own.

Always talk with your pharmacist or doctor before making changes to your medications or supplements, particularly if you take several medications or have an ongoing health condition.

No Interaction Found — But Data Suggests Molybdenum and Losartan Potassium May Share a Side Effect

This is not an interaction. Neither one changes how your body handles the other, and nothing here says they react together. What our sources do show is that each has separately been linked to the effects below — so taking both can make those effects more likely to turn up, and harder to pin on one or the other if they do. One of them is worth acting on rather than waiting out — marked below.

  • Low mood Worth acting on Additional detail

    Molybdenum

    “In one case report of a man in his late thirties, dietary supplementation with molybdenum 300-800 micrograms daily for a cumulative dose of 13.5 mg over 18 days resulted in acute psychosis with visual and auditory hallucinations, petit mal seizures, and a life-threatening grand mal attack, related to frontal cortical damage. Chelation therapy with calcium ethylene diamine tetraacetic acid (CaEDTA) was required.”

    Losartan Potassium

    Listed in the ADVERSE REACTIONS section of the FDA label for Losartan Potassium. Read the label on DailyMed ›

Reported for Molybdenum but not commonly for Losartan Potassium: hallucinations and seizures.

Effects for Losartan Potassium come from the ADVERSE REACTIONS section of its FDA label; effects for Molybdenum come from the Natural Medicines adverse-effect record, quoted above. Where a percentage is shown, it is the share of 89,498 voluntary FDA FAERS reports for Losartan Potassium that mention that effect — a reporting proportion, not an incidence rate and not evidence the drug caused it. Wording is matched across sources by our own clinical vocabulary, so treat this as a prompt to pay attention, not a diagnosis.

Pregnancy Possibly Unsafe

When used orally in high doses. Molybdenum might not be safe during pregnancy when used in doses exceeding the UL of 1.7 mg/day for women 14 to 18 years, or 2 mg/day for women 19 and older.

Lactation Likely Safe

When used orally and appropriately. Molybdenum is safe when used in amounts that do not exceed the Tolerable Upper Intake Level (UL) of 2 mg/day for breast-feeding women 19 years of age or older, or 1.7 mg/day for breast-feeding women ages 14 to 18 years.

Lactation Possibly Unsafe

About Molybdenum

What is Molybdenum?

  • Correcting molybdenum deficiency
  • Supporting enzyme function
  • General nutritional supplementation
  • Sulfite sensitivity (popular claim)

Molybdenum is an essential trace mineral your body needs in tiny amounts to help certain enzymes work. Most people get enough from a normal diet, so supplements are rarely needed unless a doctor identifies a true deficiency. At normal dietary amounts it is considered safe, but high-dose supplements should be used cautiously and under professional guidance.

Tablets, capsules, multivitamin/mineral products, liquid drops

An interaction check asks whether these two react with each other — it does not ask whether Molybdenum is a good idea for someone in your situation. Here is what our Molybdenum record says about it on its own.

Molybdenum: dosing

There is no special "treatment dose" of molybdenum for most people, because deficiency is rare and the body only needs a tiny amount. Health authorities have set recommended daily intakes that are met easily through a normal diet.If you choose to use a supplement, follow the dose on the product label and do not exceed it.

About Losartan

What Is Losartan Used For?

Brand name: Cozaar

Losartan tablets — available as branded Cozaar and several generic products — are used to treat high blood pressure (hypertension) in adults and children 6 years and older. Lowering blood pressure reduces the risk of strokes and heart attacks. Losartan tablets are also used to reduce the risk of stroke in people with high blood pressure who also have left ventricular hypertrophy (an enlarged left side of the heart). Note: evidence suggests this stroke-risk benefit may not apply to Black patients.

Losartan tablets are additionally approved to protect the kidneys in people with type 2 diabetes, high blood pressure, and signs of kidney damage (diabetic nephropathy). Arbli, the oral suspension form, shares these same approved uses.

Most-Reported Side Effects for Losartan Potassium

From FAERS, the FDA’s public side-effect reporting system (89,498 reports, all brands). Reports are voluntary and are not proof the drug caused the effect.

Taking Molybdenum and Losartan Potassium Together: Common Questions

Is it safe to take Molybdenum with Losartan Potassium?
We do not list a known interaction between Molybdenum and Losartan Potassium. That does not guarantee the combination is risk-free, so confirm with your pharmacist or doctor — especially if you take other medications or have a health condition.
Do Molybdenum and Losartan Potassium have any of the same side effects?
Yes — our sources link each of them separately to one of the same effects. That is not an interaction: neither changes how your body handles the other. It does mean that if one of those effects turns up, it can be harder to tell which one is behind it. They are listed on this page with the source behind each.
Does Losartan Potassium interact with any supplements?
Yes. Losartan Potassium has documented interactions with 253 supplements in our database — Molybdenum is not one of them. The Losartan Potassium interaction page linked on this page lists every one, ranked by severity.
