We provide sodium molybdate dihydrate powder, a key trace mineral raw material with excellent water solubility where molybdenum exists stably in the form of molybdate anions.
Sodium molybdate dihydrate exists as a white crystalline powder that dissolves rapidly and completely in water, and can be uniformly dispersed in aqueous systems or solid premixes as molybdate ions. Through strict purity control, ICP-MS trace heavy metal detection, and customized particle size and bulk density control, we have successfully solved the three core pain points of trace molybdenum supplementation: difficulty in accurate content, difficulty in uniform mixing, and difficulty in controlling impurities. This allows this "trace yet crucial" mineral to be safely, accurately, and efficiently applied to end products.

Benefits of Sodium molybdate dihydrate powder
Provides a highly bioavailable source of molybdenum: Sodium molybdate is the most common water-soluble inorganic salt form of molybdenum, completely dissociating in water into molybdate and sodium ions.
Supports the activity of various molybdenum-dependent enzymes in the body: Molybdenum is a cofactor for xanthine oxidase, sulfite oxidase, and aldehyde oxidase, participating in purine metabolism, sulfur-containing amino acid metabolism, and drug metabolism.
Supports normal purine metabolism: Molybdenum participates in the conversion of xanthine to uric acid, helping to maintain normal regulation of uric acid levels in the body.
Supports normal metabolism of sulfur-containing amino acids: As a cofactor for sulfite oxidase, molybdenum participates in the metabolism of cysteine and methionine.
Helps maintain the balance of sulfite levels in the body: Sulfite oxidase oxidizes toxic sulfites into harmless sulfates, a process in which molybdenum is indispensable.

FAQ
Q: What dietary sources provide molybdenum?
A: Dietary molybdenum is found naturally in legumes (beans, lentils, peas), grains, leafy green vegetables, liver, and dairy products. However, soil molybdenum levels vary geographically, making supplementation or fortification necessary in some regions or specialized products.
Q: Is molybdenum safe as a dietary supplement?
A: Yes. Molybdenum has GRAS (Generally Recognized as Safe) status from the US FDA for use as a nutrient supplement in foods and supplements.
Q: What is the difference between sodium molybdate and ammonium molybdate?
A: Sodium molybdate (Na₂MoO₄·2H₂O) is the preferred form for human nutrition because it is sodium-based and well-absorbed. Ammonium molybdate contains ammonia, making it less suitable for dietary supplements and food applications. Sodium molybdate dihydrate is the USP/Food Chemical Codex (FCC) standard form.
Q: Can sodium molybdate affect copper levels?
A: Very high levels of molybdenum can theoretically interfere with copper absorption and metabolism. However, dietary supplement levels are far below levels that would impact copper status. Standard multivitamin formulations that include molybdenum also include adequate copper to maintain proper mineral balance.
Q: Can it be used in tablet formulations?
A: Yes. Sodium molybdate dihydrate powder can be used in direct compression tablet blends, capsule filling, and liquid formulations.
