Understanding Molybdenum: Normal vs Optimal Ranges
Also known as: mo
?What is Molybdenum?
Molybdenum is an essential trace mineral that serves as a cofactor for several enzymes including xanthine oxidase, sulfite oxidase, and aldehyde oxidase, which are involved in the metabolism of sulphur-containing amino acids and purines. It is found in legumes, grains, and leafy vegetables. Deficiency is extremely rare.
!Why It Matters
Molybdenum cofactor deficiency (a genetic condition) causes severe neurological damage in neonates. Excessive molybdenum intake can interfere with copper metabolism, causing copper deficiency. Industrial exposure (mining, alloy production) rarely causes toxicity. Clinical testing is primarily relevant in suspected genetic enzyme deficiencies or TPN monitoring.
Reference Ranges
| Range Type | Min | Max | Unit | Note |
|---|---|---|---|---|
| Lab Normal | 0.1 | 3 | μg/L | Standard lab reference range |
| Optimal | 0.1 | 3 | μg/L | Evidence-based optimal range for health |
| Longevity Target | 0.1 | 3 | μg/L | Per longevity medicine research (Attia et al.) |
Lab normal ranges may vary between laboratories. Optimal and longevity targets are based on research literature and should be interpreted with your physician.
Symptoms of Imbalance
- Deficiency (cofactor deficiency): seizures, brain damage in infants
- Excess: gout-like joint pain, copper deficiency symptoms
How to Improve Your Levels
- 1Dietary sources: legumes (especially lentils and black-eyed peas), whole grains
- 2No supplementation needed for most people — deficiency is extremely rare
When to Test
Suspected molybdenum cofactor deficiency (neonatal seizures); TPN monitoring; research contexts.
