PRODUCT DETAILS

Unlike Thiamine Hydrochloride (Thiamine HCl), which is highly water-soluble but prone to degradation under humidity and heat, Thiamine Mononitrate is significantly more stable and non-hygroscopic (does not readily absorb moisture from the air). This superior environmental stability makes it the undisputed global industry standard for dry food fortification, flour enrichment, multivitamin tablets, and dry animal feed premixes.

Taurine

Taurine is a conditional amino acid, meaning it can be synthesized by the human body but is also obtained from dietary sources.

Ascorbic Acid

Ascorbic Acid, widely known as Vitamin C, is a naturally occurring organic compound with potent antioxidant properties. Appearing as a white to light yellow crystalline powder, it is highly water-soluble and plays a critical role in human health, food preservation, and industrial manufacturing.

Inositol

Inositol, historically referred to as Vitamin B8, is a naturally occurring sugar alcohol and a crucial component of cell membranes. It plays a vital role in cellular signaling, lipid metabolism, and neurotransmitter regulation. Appearing as a white, odorless crystalline powder with a mildly sweet taste, Inositol is highly stable and water-soluble.

L-5-Methylfolate Calcium

L-5-Methylfolate Calcium is the calcium salt form of L-5-methyltetrahydrofolate, which is the predominant, biologically active form of folate found in nature. Appearing as a white to light yellowish crystalline powder, it represents the most advanced generation of folate supplementation.Unlike synthetic folic acid, L-5-Methylfolate Calcium does not require complex enzymatic conversion in the human body. It is absorbed directly by the cells, making it the premier choice for pharmaceuticals, high-end nutraceuticals, and functional foods.

Pyridoxal-5-Phosphate (P5P)

Pyridoxal-5-Phosphate (P5P) is the metabolically active, coenzymatic form of Vitamin B6. Appearing as a white to light yellow crystalline powder, it is a vital catalyst for over 140 distinct enzymatic reactions within the human body.
