Vitamin B1 Thiamine HCl / Thiamine Mononitrate

The two dominant commercial forms of Vitamin B1: Thiamine Hydrochloride (highly water-soluble, for pharmaceutical and beverage applications) and Thiamine Mononitrate (less hygroscopic, the preferred form for dry food fortification).

White to almost white crystalline powder for both forms. Slight characteristic odor. Both forms convert to active thiamine pyrophosphate in the body and are nutritionally equivalent.

We supply food-grade, feed-grade, and pharmaceutical-grade Thiamine HCl and Thiamine Mononitrate from manufacturers in China holding ISO, Halal, Kosher and other certifications relevant to the product and production.

Common market grades include Thiamine Mononitrate Standard Food Grade (the dominant form for cereal fortification), Thiamine HCl Food Grade (for beverages and liquid formulations), Pharmaceutical Grade in both forms meeting BP/USP/EP specifications, and Feed Grade variants for animal nutrition.

Bulk and reduced-MOQ shipments. Batch-level COA covering assay, related substances, loss on drying, heavy metals, and microbiology.

Thiamine was the first B vitamin to be discovered (the source of the 'B1' designation), isolated in 1926 by Dutch and Japanese researchers investigating the nutritional cause of beriberi disease in rice-eating populations.

Industrial production proceeds by chemical synthesis through a multi-step pathway, yielding thiamine free base which is then converted to the hydrochloride salt or mononitrate salt for stability and crystallization.

Recognized as a permitted food ingredient by the U.S. FDA, the European Food Safety Authority, and equivalent regulators worldwide. Listed in BP, USP, EP, and JP pharmacopoeias. Recommended Dietary Allowance is 1.1 to 1.2 mg per day for adults.

The choice between Thiamine HCl and Thiamine Mononitrate is application-driven: HCl is highly water-soluble (1 g in 1 mL water) and preferred for liquid pharmaceutical and beverage applications; Mononitrate is less water-soluble but more stable in dry fortified foods and is the dominant form for cereal and bakery fortification globally.

Public-health significance includes mandatory fortification of rice and flour in many Asian and Latin American countries to prevent beriberi, a deficiency disease that historically killed millions in rice-eating populations and remains a concern in some regions today.

• Fortified flour, bread, breakfast cereals, and pasta; mandatory fortification in many countries (Thiamine Mononitrate is the standard form)
• Dietary supplements: B-complex, multivitamin, and energy-positioned formulations
• Pharmaceutical applications: tablets, capsules, injectable preparations, alcohol-recovery treatment
• Animal feed: poultry, swine, aquaculture, and dairy fortification
• Infant formula and clinical nutrition
• Energy drinks and functional beverages (Thiamine HCl form)
• Sports nutrition products
• Beriberi prevention in rice-based diets (the historical and ongoing public-health application)
