Around that, we add a pharmacist’s high-level view of the product as a whole — what’s inside, the evidence for its stated use, how transparent the label is, and what safety data exists — so you can see the full picture in one place. It’s educational information from our licensed clinical databases and the clinical staff at HelloPharmacist — not medical advice — and we don’t sell or endorse products. Our editorial policy

HelloPharmacist Scorecard of Molybdenum by Douglas Laboratories

Our pharmacy team’s full take, with four database checks built into the cards below — a summary of what is known, not a grade of the product itself.

What’s inside

Full disclosure
Ingredient Transparency · database check
Full

Every active ingredient lists its own amount on the label.

Why this rating?
  • The label discloses an exact amount for 1 of its 1 active ingredient.
  • No proprietary blends here — you can verify the dose of every single component.

This product contains one active ingredient: molybdenum, a trace mineral your body uses as part of enzymes that help break down certain substances. The tablet also includes microcrystalline cellulose, stearic acid, croscarmellose sodium, vegetable stearate, and silica — these are inactive ingredients that help form and hold the tablet together.

Does it work?

Strong evidence
Evidence for Intended Use · database check
By FDA rules, dietary supplements can’t claim to treat, cure, or prevent disease — so labels speak in careful marketing language. We discern each product’s intended use from its name, label claims, and label statements, then grade the clinical evidence for that use. How these ratings are computed

This product doesn't appear to be marketed for a specific use, so we graded Molybdenum's overall clinical evidence instead.

Strong

Strong clinical evidence supports Molybdenum for:

Why this rating?
  • We looked at the product name, claims, and label statements and couldn't find a stated purpose to grade.
  • Since the label doesn't commit to one use, we graded the ingredient's overall clinical evidence instead.
  • On file: Molybdenum deficiency — rated "Likely Effective" (Natural Medicines).

Molybdenum supplementation is likely effective for treating molybdenum deficiency, a rare condition. For acne, iron deficiency anemia, asthma, osteoporosis, and esophageal cancer, the evidence we hold is insufficient to rate whether it works — meaning either studies are lacking or the existing data is too uncertain to draw conclusions.

The evidence, ingredient by ingredient Molybdenum

How safe is it?

Well-documented data
Safety Information · database check
Well characterized

Adverse-effect, pregnancy, and general safety data are on file for most of these ingredients.

Why this rating?
  • We hold adverse-effect (side-effect) data for 1 of the 1 matched ingredient.
  • Pregnancy & breastfeeding safety ratings cover 1 of 1.
  • General safety write-ups exist for 1 of 1.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

Molybdenum is generally well tolerated when you stay at or below the Tolerable Upper Intake Level of 2 mg per day. The amounts in food and prenatal vitamins are considered fine.

However, high-dose supplements — especially amounts well above the daily limit — carry real risks and are rarely necessary. One case report documented severe effects (psychosis, seizures, brain damage) from doses in the 300–800 microgram range taken over weeks, requiring emergency treatment.

Additionally, people with molybdenum-containing stents should be aware of a documented contact allergy risk that may increase the chance of the artery narrowing again.

Side effects, ingredient by ingredient Molybdenum

Meds to double-check

No known interactions
Known Interaction Concern · database check
No known interactions

No medication interactions are currently documented for the matched ingredients — that isn't a guarantee none exist.

Why this rating?
  • None of the 1 matched ingredient has a documented medication interaction on file.

No interactions are documented in our data for molybdenum with any medications. Even so, always mention any new supplement to your doctor or pharmacist — they know your full medication list and can spot issues we might not see on paper.

The bottom line

Scorecard at a glanceFully disclosed formula with strong clinical evidence behind its ingredients' uses. No medication interactions are currently documented, and safety information is well characterized.

Molybdenum may help if you have a confirmed deficiency, though that's uncommon. If you're considering this supplement, talk with your doctor or pharmacist first — they can confirm you actually need it and make sure the dose fits your situation safely.

Stay well below high-dose levels, and mention it to your healthcare provider if you've ever had heart stents placed.

Molybdenum by Douglas Laboratories: Common Questions

Does Molybdenum by Douglas Laboratories interact with any medications?
We do not currently list a known interaction for the mapped ingredients in Molybdenum. This does not guarantee none exist, so confirm with your pharmacist.
How can one product interact with so many drugs?
Molybdenum contains a single active ingredient, and that one ingredient can interact with many different medications on its own. We check it against each medication and show the mechanism responsible.
Where does this information come from?
The product label data comes from the NIH Dietary Supplement Label Database (DSLD); the interaction data is built on the Natural Medicines database and reviewed by HelloPharmacist pharmacists.
What does molybdenum actually do in my body?
Molybdenum is a trace mineral that helps enzymes break down certain substances in your body. You only need a tiny amount, and most people get enough from food like grains, legumes, and nuts.
Is it safe to take molybdenum while I'm pregnant or nursing?
During pregnancy, the safety data is mixed — it's rated both likely safe and possibly unsafe, which means there's uncertainty. For nursing, dietary amounts appear fine. Talk with your doctor or midwife before taking any supplement during pregnancy or while breastfeeding.
What's the deal with the safety warning about high doses?
Food and normal supplements are safe. But very high doses (way above the recommended 2 mg per day limit) can cause serious problems — one case report documented seizures and brain damage. There's no reason to take more than your body needs.
Will molybdenum help my acne or anemia?
The evidence we have isn't strong enough to say whether molybdenum helps with acne or iron deficiency anemia. If those are concerns, talk with your doctor about proven treatments instead.
Do I actually need a molybdenum supplement?
Molybdenum deficiency is very rare. Most people get enough from everyday foods like grains, beans, and nuts. Ask your doctor if testing or supplementation makes sense for you.
