At Natural Balance, quality is among our highest priorities. To ensure you get only the best products with the best ingredients, our manufacturer, Nutraceutical, Corp., requires a certificate of analysis from each supplier to ensure product quality. But they don’t stop there. Before any material is used in our formulas, each ingredient is tested in our state-of-the-art laboratory. Nutraceutical’s lab verification procedure includes testing for heavy metals, microbes, bacteria, herbicides, pesticides, major allergens, and purity, identity, and potency. Rest assured, every batch meets the highest-quality standard – because you deserve the best.
