Product Overview
25-hydroxyvitamin D3 (25-OH-D3) is the primary circulating metabolite of vitamin D3 and can be absorbed without hepatic conversion. Our powder form is produced through a controlled chemical synthesis and coating process, delivering consistent particle size and flow properties for uniform distribution in premixes and complete feed. All three grades are supplied as microcapsules or coated granules, giving outstanding stability and consistent activity through feed processing and storage.
