HelloPharmacist Scorecard of Moly-B by Carlson

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.

Moly-B contains one active ingredient: molybdenum, a trace mineral your body uses to activate certain enzymes that help break down amino acids and other compounds. The product also includes several inactive ingredients — cellulose, maltodextrin, silicon dioxide, croscarmellose sodium, stearic acid, magnesium stearate, and ethylcellulose — which serve as fillers, binders, and capsule material.

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
Strong

Clinical evidence supports at least one of this product's ingredients for its stated purpose.

Why this rating?
  • The label markets this product for: metabolism support and enzyme activation.
  • We looked for evidence on: Molybdenum deficiency.
  • The strongest evidence on file: Molybdenum is rated "Likely Effective" for Molybdenum deficiency (Natural Medicines).

Molybdenum supplementation is likely effective for molybdenum deficiency, a rare condition in people who eat a varied diet. For acne, iron deficiency anemia, asthma, osteoporosis, and esophageal cancer, we don't have enough reliable evidence to say whether it works.

Unless you've been diagnosed with a molybdenum deficiency by your doctor, the evidence doesn't support this supplement for these other uses.

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 well tolerated and considered safe. High-dose supplements, however, are a different story.

The safety data advises against taking high-dose supplements unless your doctor recommends it — amounts should not routinely exceed 2 mg per day. At very high doses (well above what this product likely contains), molybdenum has been linked in rare cases to severe neurological symptoms including psychosis and seizures.

One case report also noted that people with molybdenum-containing stents may develop an allergy to the metal. For pregnancy, the data shows likely safety, though one rating flags possibly unsafe — talk with your doctor if you're pregnant or planning to be.

For breastfeeding, it's considered likely safe.

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 molybdenum in this product. That said, it's always smart to mention any new supplement to your doctor or pharmacist, especially if you take medications for a chronic condition.

The bottom line

Scorecard at a glanceFully disclosed formula with clinical evidence supporting its stated purpose. No medication interactions are currently documented, and safety information is well characterized.

Moly-B is straightforward: it's one mineral in a simple tablet, with no documented medication interactions. It makes sense if your doctor has told you that you have a molybdenum deficiency.

For other reasons, the evidence isn't there yet. If you're pregnant, breastfeeding, or take any medications regularly, touch base with your doctor or pharmacist before starting — not because of interactions we know of, but to make sure it fits your individual health picture.

Moly-B by Carlson: Common Questions

Does Moly-B by Carlson interact with any medications?
We do not currently list a known interaction for the mapped ingredients in Moly-B. This does not guarantee none exist, so confirm with your pharmacist.
How can one product interact with so many drugs?
Moly-B 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?
Molybdenum is a trace mineral that helps your body activate certain enzymes involved in breaking down amino acids and other compounds. You get small amounts from food, and it's essential in tiny quantities — but most people eating a varied diet get enough without supplementing.
Can I take this if I'm pregnant?
The data shows molybdenum is likely safe in pregnancy, though one rating flags possibly unsafe. Since there's some uncertainty, talk with your doctor before starting to make sure it's right for you and your baby.
Is molybdenum safe in high doses?
No. The safety data advises against high-dose supplements unless your doctor prescribes them. In rare cases, very high doses have caused severe neurological problems including psychosis and seizures. Stick to the recommended amount and don't exceed 2 mg per day without medical advice.
Does this supplement work for acne or asthma?
We don't have enough reliable evidence to say. Molybdenum is likely effective only for molybdenum deficiency, which is rare. If you're looking to treat acne or asthma, talk with your doctor about options with stronger evidence.
What are the inactive ingredients?
Moly-B includes cellulose, maltodextrin, silicon dioxide, croscarmellose sodium, stearic acid, magnesium stearate, and ethylcellulose — fillers and binders to hold the tablet together. None of these are active ingredients.
