Vitamin B1, also known as thiamine or antineuritisin, is synthesized by fungi, microorganisms and plants, but animals and humans can only obtain it from food. Vitamin B1 is mainly found in the seed skin and germ, such as rice bran and bran content is very rich, in yeast content is also very rich. Thiamine is a combination of pyrimidine and thiazole rings and is involved in sugar metabolism in the body.
Vitamin B1 plays an essential role in carbohydrate metabolism and helps support the body’s natural energy production.
Applied widely in dietary supplements, fortified foods, and daily wellness products.
Free samples available, with complete COA, TDS, and MSDS technical documents supplied.
