Omega-3s: where they are found

Omega-3 fatty acids EPA and DHA can be taken in by introducing cold-water dwelling fish into one's diet:

• mackerel
• halibut
• sardines
• salmon
• herring 

Other available sources include Perna canaliculus and krill.

Perna canalicus is a typical New Zealand mollusk, used for centuries by the Maori people to promote good health.

Krill is a crustacean that inhabits Antarctic waters.

Available forms Omega-3

However, EPA and DHA can also be taken in the form of fish oil, microalgae or shellfish supplements.

Onlyfish oil provides both EPA and DHA. In contrast, oil extracted from microalgae contains only trace amounts of EPA and considerable doses of Omega-6. Of these, the most abundant is arachidonic acid (ARA), a precursor of molecules with proinflammatory activity. For this reason in general, microalgae oil is considered an incomplete and unbalanced source of Omega-3 fatty acids. 

In addition, when you choose to enrich your diet by complementing your diet with these types of supplements, it is of paramount importance to make sure that you are dealing with products provided with a certificate of quality and guarantee of purity.

In order to protect one's health, it is necessary to use supplements in which the absence of residues of heavy metals (arsenic, lead, nickel), dioxins, furans, polychlorinated biphenyls (PCBs), mercury and other toxins that, due to industrial pollution, can accumulate in the seas from which the fish come.
