Taking fish oil is beneficial in many different ways. It is often recommended for patients with mental health concerns, cancer, heart problems, and a myriad of other conditions. Fish oil comes from the tissues of oily fish, particularly mackerel, lake trout, herring, tuna, salmon, and sardines. Secondary groups of fish that are healthy but have less omega-3 oil are halibut, river trout, catfish, cod, and snapper. Taking a fish oil supplement can deliver more benefits than eating fish alone.
Several studies have shown that people with anxiety and depression had a far lower intake of omega-3 fatty acids than those without those conditions. Adding this to the diet increases the number of serotonin — the "happy hormone" — receptors in a developing brain. For those treating anxiety, EPA omega-3 is a viable supplement. For growing children, choose DHA at the most effective dose of 2000mg per day, if your child's health care provider approves. You may only feel the benefits after three weeks on the fish oil.
