Molybdenum is an essential nutrient that we get mainly from food. It is normal and healthy to have some molybdenum in the body. Molybdenum is also a metal used in alloys, such as steel, to improve durability. Molybdenum compounds are added as flame retardants to some plastics.
Molybdenum is found in:
- Certain foods, including legumes (beans, lentils, and peanuts), nuts, rice, and liver.
- Some dietary supplements.
- Metal alloys used for a variety of applications, including:
- Artificial joints for the hip and knee.
- Welding supplies and equipment.
- Flame retardants for some plastics, such as polyvinyl chloride (PVC) plastic.
