All products are not created equally. All AGE QUENCHER™ Vitamins have been granted Natural Product Numbers (NPNs) by Health Canada. This means that our products have been assessed for quality, safety and efficacy by Health Canada. All AGE QUENCHER™ products are subject to mandatory review, approval and quality requirements. As NPN holders each batch of products produced go through third party testing for identity, purity and potency of active ingredients. Our pre-market review of products can assure you that what is on the label is what is in the bottle, and that health claims are supported by proper evidence. Please note that before taking any of our products, we recommend that you talk your health care provider.
