After I open a product, how long will it retain its labeled potency?
NOW products have an expiration date printed on the packaging. This is the date that the product will retain its labeled potency through, provided that individual product storage recommendations are followed.
Products with the instruction "keep refrigerated" on the packaging should be kept refrigerated, especially after opening. For some products, several days without refrigeration may not affect them much, but longer periods will. For other products, refrigeration ensures that the product is kept in a low humidity environment. Refrigeration is advised to extend the shelf life of many products, especially fish oils, nutritional oils, almond oil, and probiotics.
Any freshness packets or inserts you find in a NOW dietary supplement should be left in the bottle while there is still product in it. Once the bottle is empty, discard any packets before recycling.
What are the Ageless®, desiccant, and charcoal packets in your dietary supplement bottles for?
These packets are used to absorb excess moisture, oxygen or odor within the bottle, and extend the shelf life of the product. NOW and other manufacturers use Ageless® packets to extend shelf life and protect products from degradation.
