Vitamin B6 Pyridoxine HCL
Vitamin B6 Pyridoxine HCL, also known as Pyridoxine Hydrochloride, is a water-soluble form of vitamin B6 used extensively in the pharmaceutical, food, and feed industries. It is essential for protein metabolism, neurotransmitter synthesis, red blood cell formation, and immune function. As a stable and bioavailable form of B6, it is widely incorporated in dietary supplements, fortified foods, clinical nutrition, and animal feed.
Vitamin B6 Pyridoxine HCL
Primary Uses
Pharmaceutical Industry
- Therapeutic Agent: Used in tablets, capsules, and injections to treat and prevent vitamin B6 deficiency, peripheral neuropathy, premenstrual syndrome, and certain types of anemia.
- Supportive Therapy: Administered alongside isoniazid or hydralazine to prevent drug-induced B6 deficiency.
- Neurological Health: Supports cognitive function and nerve health, particularly in elderly populations.
Nutraceuticals & Dietary Supplements
- Multivitamins: Included in B-complex and energy formulas to support metabolism, reduce fatigue, and improve immune function.
- Prenatal Supplements: Common in formulations for pregnant women to prevent nausea and ensure fetal brain development.
Food & Beverage Industry
- Food Fortification: Added to cereals, baby foods, energy bars, and beverages to enhance nutritional content.
Secondary Uses
Animal Nutrition
- Feed Additive: Used to promote growth, feed efficiency, and immune support in poultry, swine, cattle, aquaculture, and pet food.
Cosmetics & Personal Care
- Skin & Hair Care: Sometimes included in formulations for scalp health, dandruff control, and overall skin wellness due to its role in protein metabolism.
Clinical & Hospital Nutrition
- Parenteral Nutrition: Incorporated into IV nutrition solutions for patients with malabsorption or undergoing long-term hospitalization.
Biotechnological & Research Applications
- Enzyme Studies: Used in cell culture and microbial fermentation processes requiring pyridoxal phosphate-dependent enzyme activity.
- Vitamin Metabolism Research: Applied in studies related to amino acid metabolism and neurological development.
