Nutrivit® Puri-D® is the gold standard for purity

Patented One-Step Process for Superior Purity and Cost Savings

Our patented enzymatic conversion process sets a new gold standard for vitamin D purity. By using a highly specific proprietary enzyme, we convert vitamin D3 into its 25-hydroxy form with no side reactions.

This streamlined approach eliminates the risks associated with multi-step fermentation then purification methods by removing steps that can cause:

  • Variability
  • Contamination
  • Supply Chain Uncertainty

THE RESULT: a high-purity, hormone-free calcidiol product you can trust, backed by science.

Efficiency that delivers real value

Our single-step process eliminates unnecessary steps and contamination risks, delivering a clean product without the need for additional processing.

By reducing the steps in manufacturing, we save money and pass those savings directly to our customers.  

  • Every batch is produced in the only vertically integrated, pharma-grade 25 Hydroxy Vitamin D facility in the world.

  • With our single-step enzymatic conversion process, there is almost zero risk of containing the 1,25 hormone

  • Every batch is 3rd party tested, and we’ve never had a single rejection. Ever.

How Nutrivit® Puri-D® works

Nutrivit® Puri-D® was developed for more efficient absorption of 25(OH)D3. Unlike traditional vitamin D3 supplements, Puri-D® bypasses the liver and is rapidly converted into 1,25(OH)2D3 in the kidneys, leading to improved vitamin D status and enhanced performance across multiple species.

Use Nutrivit® Puri-D® for healthier, stronger and more profitable birds

Optimized vitamin D bioavailability leads to superior poultry performance including:

  • Reduced incidence of leg issues
  • Improved feed conversion ratio (FCR) and body weight gain
  • Increased breast meat yield

* Different letters show treatment differences are statistically significant (p<0.01).

  • Treatments fed full or half dose of Nutrivit® Puri-D® exhibited higher circulating levels of 25(OH)D3 vs Control
  • Feeding half dose had no effect on performance
  • Circulating level of 25(OH)D3 was in proportion to the inclusion rate

Sows and their piglets thrive with Nutrivit® Puri-D®

Improve the health and performance of weaned piglets with higher levels of circulating 25(OH)D3 levels, including:
