Key physiological targets, upper safety bounds, and bioavailability metrics.
Why Molybdenum Matters
Molybdate Ion (MoO₄²⁻) • Metalloenzyme Sulfite Oxidase Cofactor
Molybdenum is absorbed in the stomach and small intestine as molybdate (MoO₄²⁻), bound to red blood cells and molybdoenzymes (sulfite oxidase & xanthine oxidase).
Consuming molybdenum-rich lentils, black beans, and firm tofu ensures rapid enzymatic oxidation of toxic sulfites into harmless sulfates.

Frequently Asked Questions: Molybdenum
Peer-reviewed answers to common questions regarding Molybdenum bioavailability, absorption, and safety.
What is the primary biological function of molybdenum in human health?
Molybdenum forms the molybdenum cofactor (Moco), an essential component of enzymes like sulfite oxidase (converting toxic sulfite to sulfate), xanthine oxidase (purine breakdown), and aldehyde oxidase.
What is the daily molybdenum requirement (RDA) for adults?
The adult RDA and FDA Daily Value baseline for molybdenum is 45 mcg/day.
What are the best plant-based sources of molybdenum?
Legumes are the richest sources: cooked brown lentils (148 mcg / 329% DV per cup), lima beans, black beans, firm tofu, oats, and almonds.
Is dietary molybdenum deficiency common?
No. Molybdenum deficiency is extremely rare in humans because legumes and whole grains provide abundant molybdenum far exceeding daily targets.
What is the upper safety limit (UL) for molybdenum?
The Tolerable Upper Intake Level (UL) for adults is 2,000 mcg/day (2 mg/day). High intake from food is excreted rapidly in urine.
How does sulfite oxidase protect brain and vascular tissues?
Sulfite oxidase uses molybdenum to oxidize dangerous sulfite molecules (produced during sulfur amino acid breakdown) into safe sulfate, preventing neural toxicity.
How efficiently is plant molybdenum absorbed?
Molybdenum in plant foods exists as soluble molybdate (MoO₄²⁻) and is absorbed at an exceptionally high rate of 80% to 90% across the stomach and small intestine.
Does cooking lower the molybdenum content of legumes?
No. Molybdenum remains stable during cooking; boiling lentils or black beans retains 90%+ of natural molybdenum.
What happens during excessive molybdenum supplementation?
Extremely high intake (>2,000 mcg/day) can overstimulate xanthine oxidase, increasing blood uric acid concentrations and triggering gout-like joint pain.
Which single plant food delivers over 300% of daily molybdenum in one cup?
Cooked brown lentils (148 mcg / 329% DV) and cooked lima beans (140 mcg / 311% DV) each deliver over 300% DV in a single 1 cup serving.
