Our Quality Guarantee

• Our products are manufactured in strict adherence to GMPs (Good Manufacturing Practices) and rigorous internal protocol. Ingredients are independently tested for purity and potency as well as for heavy metals. Our products are certified Kosher by an independent company.


• Our products are manufactured in the United States, in NSF®-certified facilities. NSF certification is optional and provides a reputable, third-party verification that manufacturers are in compliance with the GMPs. For over 75 years, NSF International has been the world leader in standards development, product certification, education and risk-management for public health and safety.


• Our ingredients and products are subjected to rigorous laboratory testing to ensure potency, quality, content and purity.


• We use the highest quality raw materials, including pharmaceutical grade components wherever available. These materials are carefully selected from the most reputable suppliers and have been tested for purity and content.


• Our products are formulated by leading experts in the fields of eyecare and nutrition science. Formulations and product updates are carefully reviewed by our Scientific Advisory Board, comprised of renowned ophthalmologists and researchers in the fields of nutrition and eye health.


• For our products that contain fish oil (HydroEye®, OmegaAdvance® and Optic Nerve Formula®), we use the first and only pharmaceutical grade fish oil to achieve US Pharmacopoeia (USP) verification – one of the most rigorous quality assurance verifications in the world. The fish oil is rigorously tested for heavy metals (including mercury, lead and arsenic) and marine contaminants; it’s sourced from cold, pristine, deep waters off South America where there are significantly less environmental impurities; and it undergoes multiple tests to ensure stability and molecular distillation, a purification process that concentrates omega-3s and helps eliminate contaminants.


• Our products are frequently updated based on new, emerging research and reflect the most current science.


• Our products are covered by a 30-day money back guarantee. HydroEye is covered by a 60-day money back guarantee.
