DHA (docosahexaenoic acid) and EPA (eicosapentaenoic acid) are two different types of omega-3 fatty acids found in fish and other sea creatures. They differ from each other in chemical structure and are present in different ratios in foods and supplements. In some products, the emphasis is more on DHA, in others on EPA, depending on the chosen formulation.

Anchovies and sardines are small fish that are low in the food chain. As a result, they naturally accumulate fewer heavy metals compared to larger fish such as tuna. These types are also rich in both DHA and EPA, which makes them very suitable for omega-3 supplements.

DHA (docosahexaenoic acid) is an omega-3 fatty acid that naturally occurs in oily fish such as salmon, mackerel, sardines, and anchovies. It is also found in algae, which is a plant-based source of DHA.
