HelloPharmacist Scorecard of Molybdenum 250 mcg by Dr. Clark Research Association Dr. Clark Zentrum

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 250 micrograms per capsule. Molybdenum is a mineral that plays a role in several enzyme systems in your body.

The remaining ingredients are rice flour, gelatin, and sodium molybdate (an inactive ingredient form of molybdenum in the capsule itself).

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, which is rare in people eating a typical diet. For acne, iron deficiency anemia (low blood iron), asthma, osteoporosis, and esophageal cancer, the evidence available to us is insufficient to say whether molybdenum helps.

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 from food and standard prenatal vitamins is generally fine. High-dose supplements, however, may cause problems and are rarely necessary—avoid them unless your doctor advises otherwise.

When taken by mouth in amounts that don't exceed 2 mg per day, molybdenum is generally well tolerated. Case reports exist of very high supplemental doses (300–800 micrograms daily over weeks) causing serious neurological effects including hallucinations, seizures, and brain damage requiring chelation therapy, though these are rare.

People with molybdenum contact allergies (sometimes from stainless steel stents) should be cautious.

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 the ingredients we hold information on. That said, check your exact medications with the search tool on this page, and confirm with your doctor or pharmacist before starting.

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 useful if you have molybdenum deficiency, which is uncommon. If you're considering it for another reason, the evidence doesn't yet support those uses.

Because high-dose molybdenum supplements carry rare but serious risks, talk with your doctor or pharmacist about whether 250 mcg daily is right for you and whether you actually need a supplement.

Molybdenum 250 mcg by Dr. Clark Research Association Dr. Clark Zentrum: Common Questions

Does Molybdenum 250 mcg by Dr. Clark Research Association Dr. Clark Zentrum interact with any medications?
We do not currently list a known interaction for the mapped ingredients in Molybdenum 250 mcg. This does not guarantee none exist, so confirm with your pharmacist.
How can one product interact with so many drugs?
Molybdenum 250 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.
What is molybdenum and what does it do in the body?
Molybdenum is a mineral that helps several enzymes work properly in your body. Most people get enough from their diet—legumes, grains, and nuts are good sources. It's rarely deficient in people eating normally.
Is this dose safe to take every day?
At 250 micrograms daily, this product stays well below the safe upper limit of 2 mg per day and should be well tolerated. That said, very high doses over time have caused serious side effects in rare cases, so stick to the label dose and talk with your doctor if you're taking it long-term for a reason other than a confirmed deficiency.
Can I take this if I'm pregnant or breastfeeding?
Pregnancy safety data shows mixed ratings—some sources say likely safe, others say possibly unsafe. Lactation appears likely safe. Because the safety picture isn't entirely clear, talk with your doctor or pharmacist before taking this supplement during pregnancy or while nursing.
Will this help my acne or anemia?
The evidence we have on file doesn't establish that molybdenum works for acne or iron deficiency anemia. If you're considering it for either condition, check with your doctor first about what the research actually supports.
What are the side effects?
At normal doses up to 2 mg per day, molybdenum is generally well tolerated with few reported side effects. Very high doses, taken over weeks, have caused rare but serious neurological effects including hallucinations and seizures. People with a molybdenum contact allergy should be cautious.
