12 Benefits of Fish Oil Supplements Rich in Omega-3 Fatty Acids

Fish is one of the most widely consumed proteins in the world, with nearly five billion pounds of fish consumed yearly in the United States. It is no wonder why it is such a popular food, since it is much lower in saturated fats than other sources of protein, high in protein, and high in Omega-3 Fatty Acids. Salmon, rainbow trout, sardines, tuna, and anchovies are all high in fatty acids, which are necessary for many healthy functions in the body that is not produced in large amounts naturally in the body.

For those who do not like the taste of fish or are worried about the potential for high levels of mercury in regular fish consumption, fish oil supplements can be a great way to reap the benefits of Omega-3 Fatty Acids. The two most important fatty acids in fish oil supplements are DHS and EPA. (1)

Below are twelve benefits of regular consumption of fish oil supplements.

1. Fish Oil Can Help With the Symptoms of ADHD

Unlike some supplements that adults can safely take but children shouldn’t, fish oil supplements can safely be consumed by people of all ages. New diagnoses of Attention Deficit/Hyperactivity Disorder, also known as ADHD, in both children and adults are on the rise in the United States, as is the prescription of potentially dangerous prescription psychotropic drugs. While severe cases of ADHD will not see enough benefits to remove medication, omega-3 fatty acids can help increase attention spans.

It is important to talk to your doctor about any supplements you are taking in conjunction with prescription medicine to ensure there aren’t any potential side effects.

2. Fish Oil Can Help to Ease Anxiety and Depression

Anxiety and depression are the two most common mental health concerns in the United States, annually affecting three million and fourteen million adults respectively. While no one fully understands the exact cause of these two illnesses, there are studies that show that the omega-3 fatty acids can help ease the symptoms. In one study, omega-3 fatty acids were found to decrease inflammation in the brain caused by two proteins: IL-6 and TNF-Alpha, which helped to lower anxiety levels in medical students. These two proteins are also lowered with anti-anxiety and anti-depression medications. These benefits have also been seen in those who suffer from bi-polar disorder, which in some cases, can be difficult to treat. (3)

3. Fish Oil Can Provide Relief from IBS

Irritable bowel syndrome is one of the most commonly diagnosed gastrointestinal conditions in the United States, and treatment plans have to be tailored to the individual’s symptoms, as not everyone with IBS presents in the same way.

There is also evidence that chemotherapy can be more effective when omega-3 fatty acids are taken regularly during treatment, and may even help reduce the side effects of chemotherapy and radiation.

However, it should be noted that recently there have been studies that have indicated that diets high in omega-3 fatty acids can actually contribute to an increased risk of prostate cancer, which are contrary to other studies suggesting that omega-3 fatty acids decrease the risk of this type of cancer.

However, by avoiding fish, pregnant women are missing out on the healthy benefits of omega-3 fatty acids for both themselves and their unborn child. (9)

Women who consume enough of these fatty acids decrease their risk of both pre- and post- natal depression as well as gestational-diabetes. It also ensures that women do not experience premature labor. For the unborn child, a healthy amount of omega-3 fatty acids throughout the pregnancy contributes to more brain development in the uterus. This increased development is evident for years after birth. It also helps prevent any ocular issues that can occur in newborns. Many benefits of fish oil are transferred to the fetus through the placenta.

Omega-3 fatty acids can help to promote healthy memory and prevent brain shrinkage, a common hallmark of Alzheimer’s disease. (10) It is interesting to note that those in countries who consume the Mediterranean diet, which is characterized by lean protein, including fish, and plenty of fruit and vegetables, have much lower rates of Alzheimer’s than the United States. While genetics can play a part in the development of Alzheimer’s, a healthy diet full of produce and omega-3 fatty acids can play a huge role in prevention.

Fish oil, being high in good cholesterol, raises the levels of HDL in the body, removing bad cholesterol from the body.
