The capsules smell, taste or look different from what I am used to

Algae oil is a natural product and due to the nature of the oil some variability in the clarity of the product has been observed. With long-term storage at cooled temperature conditions, some semi-solid material may appear in the oil. This is not expected to adversely affect the quality of the product, but the oil must be mixed well to re-suspend this material before use.

Because fish get their Omega-3 from consuming algae, the smell and taste of fish and algae oil are related to each other.
