D-VITIX™ D₃ — Nature's Boost.
Rapid absorption for stronger livestock.
A 25-Hydroxyvitamin D₃ (Calcifediol) feed additive that bypasses hepatic hydroxylation — delivering the active metabolite directly to where it's needed for calcium metabolism, skeletal integrity, immune resilience, and reproductive performance.

Pellet-feed compatible
Cool, dry, sealed
What It Is — and why it works faster.
Conventional Vitamin D₃ (cholecalciferol) requires hepatic conversion to 25-Hydroxyvitamin D₃ before it can act on calcium and phosphorus metabolism. D-VITIX™ delivers the active metabolite directly — bypassing that liver-dependent step entirely.
D-VITIX™ D₃ is 25-Hydroxyvitamin D₃ (Calcifediol). Unlike cholecalciferol, it bypasses the liver's first hydroxylation step and rapidly elevates serum 25(OH)D₃ levels — within 48–72 hours in feeding studies. The result is faster physiological impact on calcium and phosphorus regulation, immune cell signaling, and reproductive performance.

Dosing Matrix — two concentrations, one chemistry.
D-VITIX™ ships in two active concentrations. 1.25% is the high-efficiency choice for low-inclusion premixes — typical for integrators optimizing formulation efficiency. 0.05% offers higher-inclusion flexibility for commercial feed mills and pre-starters.
D-VITIX™ D₃ 1.25
High-efficiency inclusion for low-dosage premixes. Preferred by integrators seeking formulation efficiency in vitamin/mineral premixes and concentrated feed blends.
D-VITIX™ D₃ 0.05
Higher-inclusion flexibility for feed manufacturers. Easy to dose across compound feed, pre-starters, and customizable premix formulas. Suited to commercial mills and specialty feeds.
Best results achieved under well-balanced nutrition programs with adequate calcium and phosphorus levels. KYNAD technical team provides customized dosage recommendations based on livestock species, production goals, and feed format.
