50-150mcg daily
With or without food, Any time of day
Sodium Molybdate or Molybdenum Glycinate
1 serving daily (as directed on label, typically 1-2 tablets/capsules)
With breakfast, With lunch (if GI sensitive)
Capsule or softgel
Combined supplementation is unlikely to be clinically significant at standard doses. Excessive molybdenum may impair copper status over time.
Keep total molybdenum below 2000 mcg/day from all sources. Standard multivitamin molybdenum content is well within safe limits and rarely requires additional supplementation.

Effects of cocoa extract and a multivitamin on cognitive function: A randomized clinical trial
Alzheimer's & Dementia (2023) · Rct · n=2262
Multivitamin-mineral supplementation (not cocoa extract) drove significant cognitive improvements in COSMOS-Mind
Limited direct RCT evidence. One controlled trial showed effects on metabolic parameters with molybdenum intervention. Conservative estimates given sparse human data and reliance on mechanism-based extrapolation from enzyme cofactor function.
Based on COSMOS trials (n=5765) showing equivalent of 2.0 years cognitive decline prevention. Effects most pronounced in those with cardiovascular disease. Study duration was 3 years. Effectiveness reflects conservative interpretation of memory and global cognition improvements.
AI-estimated from published studies. Interpret as directional guidance.
Multivitamin has a higher evidence score (6/10 vs 3.5/10) and wins in 2 of 3 categories.
For reduce inflammation, Molybdenum has a higher relevance score (60 vs 50).
Combined supplementation is unlikely to be clinically significant at standard doses. Excessive molybdenum may impair copper status over time. Keep total molybdenum below 2000 mcg/day from all sources. Standard multivitamin molybdenum content is well within safe limits and rarely requires additional supplementation.
