                                According to research published by the National Institutes of Health, over 50% of retail fish oil products tested in one study exceeded voluntary oxidation limits, a primary factor that determines the shelf life of liquid fish oil. This means that while the expiration date is a guide, proper storage is crucial for maintaining the quality and effectiveness of your supplement.
