Molybdenum 500 by Seeking Health

If wine, dried fruit, or packaged foods trigger headaches or flushing, you’re likely reacting to sulfites, and a molybdenum supplement can help. It’s also useful if you’re taking sulfur-heavy products like NAC or MSM and feel “sulfur intolerance.” Most healthy adults who eat legumes and whole grains get enough; this higher-dose capsule is for targeted use, not daily multivitamin duty. If you track labs, keep an eye on Uric Acid and Copper, Serum if using long term.

Molybdenum is the mineral cofactor that turns on sulfite oxidase, the enzyme that converts sulfite into sulfate for easy excretion. It also powers aldehyde oxidase, which helps clear acetaldehyde from alcohol and other aldehydes, and xanthine oxidase, which makes uric acid from purines. That explains both the upside for sulfite intolerance and the downside: higher doses can nudge Uric Acid upward in susceptible people. It does not meaningfully chelate heavy metals despite online claims.

Seeking Health suggests one capsule daily with food. In practice, 500 mcg is a high dose, so many patients start with one capsule every other day for 1 to 2 weeks, then adjust based on symptoms. You can time it before a known sulfite exposure, or use short courses during periods of high sulfur intake. For maintenance beyond a few weeks, consider stepping down to a lower-dose molybdenum.

If you have gout or a history of high Uric Acid, avoid high-dose molybdenum or use only with clinician guidance and lab monitoring. Long-term high intake can lower copper status; watch for low Copper, Serum or low ceruloplasmin, new anemia, or hair pigment changes. Pregnancy and breastfeeding: use only if your clinician recommends it. This is not a substitute for limiting high-sulfite foods if you are very sensitive.
