What is Zinc picolinate?
Zinc picolinate (CAS 17949-65-4) is a zinc salt of picolinic acid used as a bioavailable zinc source in nutritional and functional product formulations.
Where is Zinc picolinate used?
- Dietary supplements: elemental zinc delivery in capsule, tablet and powder formats where absorption efficiency is a key criterion
- Personal care: antimicrobial and sebum-regulating activity in anti-acne creams and scalp treatments
- Animal nutrition: chelated zinc source in premixes and compound feeds
- Pharmaceutical formulators use it in nutraceutical and OTC product development where a well-tolerated, organic zinc form is specified.
Good to know: Its chelated structure supports efficient zinc delivery compared to inorganic zinc salts.
Commercial specifications
- Elemental zinc content verified by certificate of analysis for every batch
- USP and FCC standards
- Bulk supply in kilogram and metric-ton quantities
