Best Fish Oil for Anxiety (15+ List)

Salmon Oil

In 2014, a team of researchers found that long-term dietary intervention using Atlantic salmon significantly reduced anxiety in subjects. They investigated the effects of consumption of salmon oil on underlying biological mechanisms associated with anxiety. These included physiological measures such as heart rate variability (HRV) and heart rate. 

Salmon oil comes with loads of health advantages, which is why it is a highly sought after dietary supplement. It can prevent inflammation, improve blood flow, support foetal development, and is good for the skin and eyes.

Cod Liver Oil

Another such study done back in 2007 found similar results for cod liver oil on symptoms of depression and anxiety. This team wanted to check whether the oil, rich in omega-3, could help with neurotransmitter regulation. They measured these symptoms using The Hospital Anxiety and Depression Scale (HADS). 

Their findings indicated a negative association between the regular use of cod liver oil and high levels of depressive symptoms. So if you are dealing with anxiety or its common comorbidity depression, add cod liver oil to your staples.

Nordic Fish Oil

The Nordic diet has been established to have a negative association with symptoms of depression and anxiety. This diet includes the regular intake of Nordic fish oil. Many brands have capitalised on this information and started selling Nordic fish oil capsules. 

But, Nordic Naturals is a brand with published research backing its product’s effectiveness. Their fish oil supplement has been proven to reduce anxiety, especially in people with a history of substance abuse.

Krill Oil

Krill oil has been shown to not only lower anxiety but also improve cognitive function. Moreover, it can also help relieve many symptoms of PMS and other menstrual issues. 

It is safe to say that regular intake of krill oil is excellent for mental health and more people should be consuming it. Krill oil can also help with physical health by lowering cholesterol, swelling, and blood clotting.

Herring Oil

A scientific investigation revealed that fish oil containing herring oil was successful in lowering anxiety in pregnant women. It is a substance that is safe to eat for women who are pregnant or breastfeeding. 

Other than lowering anxiety, it can also help with many physical conditions. As it is packed with omega-3 fatty acids, it can regulate heart function and does wonders for foetal development.  Herring oil is rarely sold separately and usually comes as a mix of many fish oils.

Anchovy Oil

Another oily fish is the anchovy, which is more popular for its use in salads and sandwiches. According to this scientific review, anchovy oil is one of the few rich and natural sources of docosahexaenoic acid, also known as DHA.

DHA is a fatty acid abundant in brain cell membranes. It contributes to the normal development of neural and retinal tissues throughout human life. A deficiency of DHA is linked to neuropathology, which includes anxiety. Start consuming more anchovy oil to prevent this.

Mackerel Oil

Mackerel is a common name for pelagic fish belonging to the Scombridae family. These are highly nutritious fish as they provide us with protein and essential fatty acids. This nutritional guide to reducing stress and anxiety recommends the consumption of mackerel to prevent anxiety disorders.

Eating mackerel often can also help you recover from fatigue, improve stamina, and get better skin. If you don’t want to eat the fish meat, these capsules can deliver the same benefits without it.

Tuna Oil

A distant relative of the mackerels is the tuna, a saltwater fish generally used in sandwiches, salads, cutlets, and curries. The high levels of omega-3 fatty acids in this fish can reduce levels of other bodily fats that cause heart disease. 

As we’ve mentioned several times earlier, these good fatty acids also play a role in anxiety prevention and treatment. This 2011 study even demonstrated that tuna oil supplements can improve cognitive functions. What better reason to try these tuna fish softgels!

Sardine Oil

Also called pilchards, sardines are mostly seen as smelly fish stacked into cans, mostly used as bait. While some people enjoy the taste of sardines, it’s definitely not a universal favourite. 

However, since sardines are oily fish, they are used to make omega-3 supplements like this one. This nutrition review found a relationship between omega-3 sources like sardines and the prevention of depression and anxiety. Maybe that should change your mind about including sardines in your diet.

Alaskan Pollock Oil

This fish gets its name because it is widely distributed in the North Pacific Ocean and densely concentrated around the Bering Sea. The Alaskan pollock is popular in healthy diets because it is high in lean protein and low in saturated fat. It also provides us with Vitamin B12, phosphorous, and selenium.

A recent Indian study revealed an association between Vitamin B12 deficiency and anxiety. Since the Alaskan pollock gives at least two nutrients that fight anxiety, you might want to consider eating these capsules.

FAQs (Best Fish Oil for Anxiety)

How much fish oil should I take for anxiety?

You can take a daily dosage of anything between 200-2200 mg of fish oil per day for anxiety. However, if you have a mood disorder, it’s better to take a higher dose of fish oil supplements.

Can fish oil make anxiety worse?

If you stick to the recommended dosage specified by trusted sources like a doctor or nutritionist, this is unlikely to happen. Most of the research on the topic only talks about the benefits of fish oil. So, to avoid this possibility, only take as much fish oil a day as is established safe.

Does Omega-3 calm you down?

As previously cited throughout this article, it has been found that omega-3 fatty acids do have an improving effect on anxiety. It can help you calm down by improving nutrition and digestion. This promotes homeostasis and activates the parasympathetic nervous system, which is the antithesis of anxiety.
