Introducing SynChill™ Pure
Pure Confidence, Pure Safety
The competitive environments in which horses perform are inherently unnatural—separated from their herd, surrounded by movement, noise, and predators (humans) on all sides. Their heightened awareness, a vital survival instinct, can make them unpredictable and reactive, compromising both performance and safety.

Why is the NASC Quality Seal Important?
For horse owners evaluating supplements, NASC (National Animal Supplement Council) certification is one of the clearest indicators of product quality and manufacturer accountability.
In practical terms, it means the company follows audited quality control standards that incorporate FDA regulations 21 CFR Part 507 (animal food safety and preventive controls) and 21 CFR Part 111 (dietary supplement cGMPs). Certified companies are required to maintain traceable ingredient sourcing, standardized manufacturing procedures, and documented batch records , reducing the risk of contamination, mislabeling, or inconsistent dosing.
NASC certification also requires adverse event reporting and labeling compliance , which adds a layer of transparency and oversight that is otherwise limited in the animal supplement space. For the consumer, this translates to greater confidence that what is on the label is actually in the product and in the stated amounts
In a market where supplements are not “approved” by the FDA, NASC certification serves as a practical proxy for credibility, safety, and consistency, helping horse owners make more informed purchasing decisions.
