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.
What’s inside
Full disclosure
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
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.
How safe is it?
Well-documented data
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
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.
