HelloPharmacist Scorecard of Molybdenum 500 mcg 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.

From our pharmacy team — supplement deep dive

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, an essential mineral your body needs in small amounts for proper enzyme function and metabolism. At 500 micrograms per capsule, it's designed to help meet your daily molybdenum needs.

The capsule also contains microcrystalline cellulose, gelatin, vegetable stearate, and silica as inactive ingredients.

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 is likely effective for treating molybdenum deficiency — a rare condition in people eating a typical diet. For acne, iron deficiency anemia, asthma, osteoporosis, and esophageal cancer, the evidence is too limited to know whether molybdenum supplements help.

These ratings reflect what we know from the available research, but they don't rule out other uses your doctor might consider.

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 at normal dietary amounts and those in standard prenatal vitamins is generally well tolerated. This 500 mcg dose is well below the safe upper limit of 2 mg per day set for adults.

However, the safety data flags concern with long-term high-dose supplementation — one case report documented severe neurological problems (psychosis, seizures, and toxic brain damage) in a man who took 300–800 mcg daily over 18 days. For pregnancy, dietary amounts and standard prenatal doses are likely safe, though high-dose supplements should be avoided unless your doctor advises otherwise.

Lactation safety data shows likely safety at normal levels.

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 the ingredients we could check. Before you start, mention this supplement to your doctor or pharmacist, especially if you take medications that affect mineral absorption or if you have kidney disease.

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.

This product is appropriate if you've been diagnosed with molybdenum deficiency or your doctor has recommended it. For other purposes, the evidence doesn't yet support its use.

At the 500 mcg dose, it's unlikely to cause problems if taken as directed — but avoid taking much higher doses on your own. Talk with your doctor or pharmacist about whether you actually need a molybdenum supplement, since most people get enough from food.

Molybdenum 500 mcg by Douglas Laboratories: Common Questions

Does Molybdenum 500 mcg by Douglas Laboratories interact with any medications?
We do not currently list a known interaction for the mapped ingredients in Molybdenum 500 mcg. This does not guarantee none exist, so confirm with your pharmacist.
How can one product interact with so many drugs?
Molybdenum 500 mcg 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.
Does this molybdenum supplement actually do anything?
It's likely effective if you have molybdenum deficiency, which is rare in people eating a normal diet. For other conditions like acne or asthma, there isn't enough reliable evidence to say whether it helps. Your doctor can test whether you're deficient and tell you if you really need it.
Is 500 mcg a safe dose?
Yes, 500 mcg is well below the safe upper limit of 2 mg per day. At this dose taken as directed, molybdenum is generally well tolerated. The safety concern comes from much higher doses taken over time — one case report documented serious neurological problems at 300–800 mcg daily over 18 days.
Can I take this if I'm pregnant or breastfeeding?
Dietary amounts of molybdenum and doses in standard prenatal vitamins are likely safe during pregnancy. High-dose supplements should be avoided unless your doctor recommends them. Lactation appears safe at normal levels. Talk with your doctor before starting any supplement while pregnant or nursing.
What is molybdenum actually for in my body?
Molybdenum is an essential mineral that helps your body run enzymes involved in metabolism and other vital functions. You need only small amounts, and most people get enough from food like grains, legumes, nuts, and vegetables.
Will this interact with my medications?
No interactions are documented in our data for this ingredient. That doesn't guarantee none exist, so mention this supplement to your doctor or pharmacist before you start, especially if you take medications that affect how your body absorbs minerals.
