Fish Oil Does Not Improve Brain Function In Healthy People

How to Use Fish Oil For Weight Loss & Fat Loss (Dosing, Duration & More)

This article has discussed the effects of fish oil on Alzheimers disease and mild declines in brain function, but many wonder about its effects in people with normal brain function.

Observational studies report that eating more omega-3 fatty acids from fish is significantly correlated with better brain function. However, these studies evaluated fish consumption, not fish oil supplements.

Furthermore, correlational studies like these cant prove cause and effect .

Most of the higher-quality controlled studies agree that supplementing with omega-3s from fish oil does not appear to improve brain function in healthy individuals with no existing memory problems.

In a study of 159 young adults, taking supplements containing 1 gram of fish oil per day did not improve brain function, compared to a placebo .

Similarly, multiple studies in older adults have shown that taking fish oil supplements did not improve measures of brain function in people with no memory problems .

Summary Clinical studies have shown that healthy people with normal brain function did not see improvements in brain function after taking fish oil supplements.

Clinical Evidence Of Brain Benefits

A number of studies have demonstrated the benefits of omega-3 fatty acids on brain functioning. One study, published in the June 2006 issue of the journal, “Experimental Gerontology,” showed that omega-3 supplementation provides a mild protective effect against the development of age-related cognitive impairment. Another study, published in the November 2005 issue of the “European Journal of Clinical Investigation” studied the effects of omega-3 supplementation on cognitive functioning and mood in healthy volunteers. The results found a beneficial effect on attention and complex cortical processes as well as improved mood. A systematic review published in 2006 in the journal, “Dementia and Geriatric Cognitive Disorders” states that limited clinical evidence suggests that omega-3 supplementation may help reduce the risk of dementia. Despite these results, more clinical studies are needed to evaluate the specific benefits of flaxseed oil on cognitive functioning.

What Are Fish Oil Omega

Omega-3 fatty acids are polyunsaturated fats responsible for most of the brain and mental health benefits of fish oil.

Fish oil primarily contains two types of omega-3 fatty acids EPA and DHA.

These two fatty acids are components of cell membranes and have powerful anti-inflammatory functions within the body. They are also well known for their critical roles in human development and heart health .

In the human diet, EPA and DHA are almost exclusively found in fatty fish and fish oil. Because most people do not consume the recommended amounts of fish, many people likely fall short of getting enough EPA and DHA in their diets .

The body can make EPA and DHA out of another omega-3 called alpha-linolenic acid . ALA is found in a number of food sources, such as walnuts, flaxseeds, chia seeds, canola oil, soybeans and soybean oil.

However, humans cant convert ALA to EPA and DHA very efficiently, with estimates reporting that less than 10% of the amount of ALA you consume is converted to EPA or DHA .

Therefore, taking fish oil may be a good option, especially for those who dont eat much fish but are still looking to gain some of the health benefits of omega-3 fatty acids.

Summary EPA and DHA are the two primary omega-3 fatty acids found in fish oil. Because people often fall short of their recommended fish intake, fish oil supplements may be a convenient alternative to give you the health benefits of omega-3s.

Does That Mean Fish Oil Makes Me Smarter

The fish oil you get from eating healthy amounts of fish each week is good for your brain. That is clear. However, it is not necessarily the case that higher amounts of fish oil will inevitably boost your cognitive abilities beyond the benefits you will get from simply getting enough fish oil from fish.

Taking fish oil does not make you smarter or help you remember when you already have an adequate intake Explains Dr. Hussein Yassine, Keck Medicine Endocrinologist at USC in Los Angeles and Associate Professor of Medicine at USCs Keck School of Medicine

Unfortunately, more is not better when you are already at the beginning of the study. This is not a smart pill you cant take it and remember things, he adds.

Omega Fatty Acids Reduce Inflammation

Inflammation has recently been the focus in the search;to understand Alzheimers Disease. While inflammation’s relationship to;Alzheimers Disease is;not completely understood, we know that inflammation can contribute heavily to the deterioration of the brain seen in Alzheimers Disease. Omega Fatty Acids;reduce this inflammation and some studies have subsequently found that Omega Fatty Acids;reduce the likelihood of Alzheimers Disease and cognitive decline.

Fish Oil May Benefit Mild Memory Loss

The omega-3 fatty acids found in fish oil play important roles in brain function and development. There are also claims that fish oil can improve brain function in people with memory problems, such as those with Alzheimers disease or other cognitive impairments.

Alzheimers disease is the most common type of dementia and impacts brain function and quality of life in millions of elderly adults. Finding a supplement that could improve brain function in this population would be a major, life-changing discovery.

Unfortunately, a review of the research found no compelling evidence that omega-3 supplements like fish oil improve brain function in people with Alzheimers disease .

On the other hand, several studies have suggested that taking fish oil supplements may improve brain function in people with more mild types of brain conditions like mild cognitive impairment or age-related cognitive decline .

These types of conditions arent quite as severe as Alzheimers disease, but they still result in memory loss and sometimes other types of impaired brain function.

One study gave 485 older adults with age-related cognitive decline either 900 mg of DHA or a placebo every day. After 24 weeks, those taking DHA performed better on memory and learning tests .

Based on this research, it appears that fish oil supplements may be most beneficial when people start taking them in the early stages of brain function decline. If you wait too long, fish oil may be of little benefit to the brain.

Three Strategies To Try Instead

Do a brain workout. Enhancing reasoning and memory abilities learning a new language, for instance might help delay or slow decline. A 10-year trial found that such training can help increase cognitive processing speed and sharpen reasoning skills.

Exercise your body. In 2011, one study estimated that a million cases of Alzheimers disease in the United States were caused by sedentary lifestyle. Several studies have found that physical activity walking, weightlifting, yoga or tai chi, for example may delay or slow cognitive decline but not prevent it.

Manage blood pressure. Lowering blood pressure dramatically reduces the risk of heart disease and stroke, which are risk factors for memory loss.

Possible Fish Oil Side Effects

Some people who are hypersensitive to fish or have a known allergy to fish products may have a negative reaction to fatty acids which were derived from fish. Some fish oil tablets are also produced with alpha-linolenic acids which come from nuts, which may aggravate those which have an allergy to these products. In many cases these allergies will manifest themselves as a skin rash, but the symptoms could be more severe depending on the severity of your allergies. People with this concern will need to avoid using these products.

In some cases, fish oil pills may cause loose stools, nausea, diarrhea, and decreased appetite, fat in the stools, vomiting or constipation. These side effects can be minimized by taking a fish oil capsule that is coated, which is designed to help eliminate the “fish burps” many users complain about. Starting with low doses of the supplement and working up to a full dose can also help minimize side effects. You can also pair fish oil supplements with meals so that they enter your body more slowly, minimizing the risk of side effects occurring.

Can Fish Oil Improve Your Health

The American Heart Association recommends consuming oily or fatty cold-water fish twice a week. Fish is one of the best ways to get your omega-3 fatty acids intake and reap its numerous health benefits. It is an excellent source of protein and, in comparison to other fatty meat products, it has low saturated fat.

However, if youre a vegetarian or do not consume fish, you can consult your doctor for dietary alternatives to fish and fish oil.

Lets look at some of the fish oil benefits for men, though some of these benefits also apply to everyone.

1. Fish Oil Can Boost Male Fertility

Various research studies have suggested that Omega-3 improves semen quality, volume, erectile function and even prevents prostate cancer.

Recently, the first observational study on the association between fish oil supplementation intake and improved testicular function conducted also showed these supplements to be beneficial to mens health. The study was conducted on 1,700 young, healthy Danish men who averaged around nineteen years of age. Those who took fish oil supplements reported higher semen volume and improved sperm quality. Those who took other supplements, such as multivitamins did not show the same effects, pointing to possible links between fish oil supplements and better sperm counts.

Other studies have also found positive associations between fish oil supplements and sperm quality.

Contextual Fear Conditioning Test

The contextual fear conditioning test was conducted as reported previously,,. Mice were first habituated to the behavioral room, and were then allowed to freely explore the apparatus for 3min. During training, mice were placed in a conditioning chamber A, and exposed to tone-foot-shock pairings , with an interval of 80s, 24h after training. Mice were returned to the chamber A to evaluate contextual fear learning. Two hours later, cued fear conditioning was performed. Each mouse was placed into novel chamber B, monitored for 3min. Freezing during training and testing was scored using Med Associates Video-Tracking and Scoring software. Data were analyzed using a two-tailed Students t-test or one-way ANOVA and the Bonferroni test.

Fish Oil Sources And Why It Could Be A Good Catch


Fish oil is primarily found and extracted from oily fish varieties, such as salmon, tuna, mackerel, sardine, herring, and trout. It contains two highly beneficial types of omega-3 fatty acids for many health conditions:

  • Docosahexaenoic acid
  • Eicosapentaenoic acid

But heres the catch: your human body cannot make omega-3 polyunsaturated fatty acids. You are dependent on food sources to supplement these vital nutrients. But this is not a big deal since you could consume foods that are rich in omega-3 fatty acids, such as oily fish, or consume fish oil in the form of supplements.

As a side note, you can also find another type of omega-3 fatty acid called alpha-linolenic acid in some plant sources, such as walnuts, flax seeds, pumpkin seeds, and chia seeds. You cannot find alpha-linolenic acid in fish oil, and interestingly, your body converts ALA into DHA and EPA, but in very small amounts. So, if you want your Omega-3 in balance, you will have to consume DHA, EPA, and ALA via food sources or supplements or a combination of both.

Fish Oil May Improve Depression

Finding treatments for depression and other mental health disorders continues to be a public health priority, and the desire for non-medicinal interventions to improve symptoms will likely increase.

People have long thought that fish oil is linked to improvements in mental health, but does the research actually back up this claim?

A recent review of clinical studies concluded that taking fish oil supplements improved depressive symptoms in people with depression, with effects comparable to those of antidepressant medications .

However, the greatest improvements in depressive symptoms seemed to occur in people who were also taking antidepressants. Additionally, people tended to see greater effects when the fish oil supplement contained higher doses of EPA .

It is still unclear how EPA and omega-3s improve depressive symptoms.

Researchers have suggested it may be related to their effects on serotonin and serotonin receptors in the brain. Others have proposed that omega-3s from fish oil could improve depressive symptoms through anti-inflammatory effects .

Additional evidence suggests that fish oil may improve other mental health conditions like borderline personality disorder and bipolar disorder.

However, more high-quality research is needed before the medical community can make definitive recommendations .

Dha May Benefit Alzheimers Patients Without Apoe

Then, study participants were divided into two groups depending on whether they had the so-called ApoE-e4 gene variant. Itâs associated with an increased risk of developing Alzheimerâs disease.

In the people who had the ApoE-e4 gene variant, there was again no benefit from DHA treatment. In contrast, those without the ApoE-e4 gene variant who received DHA had a slower rate of memory decline.

âThis is an intriguing provocative result, but requires further study for confirmation,â Quinn says.

He says itâs a mistake to compare this study to the one in healthy adults because they looked at such âvery different populations of patients.â

But the conflicting findings raise the possibility that treatments for Alzheimerâs have to be given âvery, very earlyâ to be effective, Thies says.

What Are The Benefits Of Fish Oil For Memory

Eating a diet rich in fish is good for your brain and preserving long-term cognitive function. Whether supplements can deliver the same benefit is much less clear.


Whered you put those keys again? What did you come in this room for? And remember that thing you needed to, um, remember for work? If only taking something like a fish oil supplement could bust through all your brain snags.

While the research is mixed on fish oil supplements, its clearer that its good for your brain when it comes to consuming fish oil via food . Overall, research shows that fish intake helps with cognitive health and helps prevent a decline in cognitive abilities, says Puja Agarwal, PhD, a nutritional epidemiologist and assistant professor of internal medicine at Rush University Medical Center in Chicago. And the good news is that you may be able to reap these benefits with just one serving of fish per week, she says.

Heres why fish is thought to be so good for your brain. Fish oil contains certain omega-3 fatty acids, particularly EPA and DHA , notes the National Center for Complimentary and Integrative Health . You can consume fish oil via eating fresh fish or seafood or by taking a supplement.
