Is omega-3 good for anxiety? Let’s take a closer look

What are omega-3s?

Omega-3 fatty acids are nutrients that surround cells, nourishing and strengthening them. There are three acids that make them up:

  • Alpha-linolenic acid (ALA)
  • Docosahexaenoic acid (DHA)
  • Eicosapentaenoic acid (ELA)

The acids are essential fatty acids, which means you must consume them. Your body can’t produce them. ALA comes mainly from vegetable oils, such as soybean or canola. DHA and ALS are found in seafood such as salmon and tuna, which is why many omega-3 supplements are fish oils.

Scientists recommend that healthy adult men get about 1,600 milligrams of ALA per day and healthy adult women take 1,100 milligrams. There is no standard for DHA or ELA.

There are several studies on the impact of omega-3s on the body. They are important for brain, eye, heart, respiratory, and reproductive health. They also contribute to a healthy endocrine and immune system. They also have mental health benefits.

Is omega-3 good for anxiety?

Anxiety relief is one of many health benefits of omega-3. Evidence supports that omega-3s can help relieve anxiety symptoms through their impact on the brain. DHA can significantly affect your neurotransmitters and slow down your brain’s ability to process glucose. TO 2018 meta-analysis of 19 different studies found that people taking high doses of omega-3s (up to 2,000 milligrams) had reduced anxiety symptoms.

Anxiety may be caused by your brain not effectively processing and sending messages to your nervous system. Omega-3s improve processing capacity, which can affect anxiety. It also affects your memory and ability to learn, which can prevent situations that cause anxiety.

Doctors do not recommend using omega-3s as a replacement for psychiatric medications, but with proper medical guidance, adding one to your treatment plan could help.

How to get more omega-3s in your diet

You can get omega-3s through a varied diet that includes varieties of seafood, especially fatty cold-water fish like herring and mackerel. They contain both DHA and ELA. Nuts and seeds like chia and walnuts have ALA. You can also get omega-3s through fortified foods. It is added to some eggs, milk and other dairy products and juices.

Most people get enough omega-3s in their diet for physical health. Being ineffective can lead to an inflamed, scaly rash.

You can increase your intake with dietary supplements. Krill, cod, and algae oil come in capsules that you can take in various doses. Taking them may give you a higher daily dose than you would otherwise get. If you eat some omega-3-rich foods but have symptoms of anxiety, a supplement may help. Normally you shouldn’t have more than 5,000 milligrams. You can often tell if she’s had too much by an upset stomach, heartburn, headaches, or smelly sweat.

Always check that a supplement does not negatively interact with another medication. One of the main interactions of omega-3 supplements is causing bleeding in people taking blood thinners.

Overall, omega-3s are a relatively safe way to improve anxiety symptoms.

Other dietary strategies

Omega-3s aren’t the only supplement that can help. You can also consider these options.

Vitamin D

Hydration is essential for life and water has calming elements. You can get it by drinking non-alcoholic, non-caffeinated drinks. Many foods also contain some water; Grapes, watermelon and celery have high water content. When you’re dehydrated, your brain doesn’t work as efficiently, which makes you nervous. Having four to six glasses per day can keep you sufficiently hydrated.

A high-fat, moderate-protein, low-carbohydrate diet, such as the ketogenic diet, can improve your ability to use antioxidants. There is debate about whether the ketogenic diet is healthy in the long term, so it may be better as a short-term booster.
