A more white or cloudy color may appear due to the presence of Stearic Acid. This is a safe, non-toxic, and naturally occurring saturated fatty acid that comes from the production of both animal and plant fat/oil.
Because our oil is sourced only from wild fish, the amount of Stearic Acid (and resulting white or cloudy color of the oil) will vary depending on where and what type of food the fish were finding before they were caught. Oils with a higher stearic acid content will become even more cloudy when refrigerated.
If the oil is opened before the expiration date, it is safe to use.
