Omega-3 fatty acids are a special type of polyunsaturated essential fatty acids found primarily in cold-water fish and purified fish oils.  They help to maintain the health of your heart, brain, eyes, skin, hair, joints and immune system.

These fatty acids are actually necessary for your overall health. But since your body doesn't have the ability to produce them, you need to get them from food sources or dietary supplements. 

Here are some of the benefits of omega-3 fatty acids:

1. It helps to reduce menstrual cramps.

Omega-3 can help to reduce menopausal symptoms and menstrual cramps, and headaches.  It is also known to help combat breast cancer.  Low concentrations of fatty acids are linked to menstrual discomfort in women. 

2. It helps to improve cardiovascular health.

The greatest benefit of omega-3 to your health is its ability to lower bad cholesterol levels and high blood pressure.  This can greatly help to boost cardiovascular health. 

3. It helps to alleviate inflammation.

Omega-3 contains anti-inflammatory properties which help to alleviate inflammation due to joint problems, asthma, arthritis and osteoporosis.  Its ability to lower bad cholesterol levels is a plus for diabetics and people with heart problems.

4. It helps to fight cancer.

Several studies suggest that omega-3 fatty acids contain properties which help to prevent or even reverse the progression of certain types of cancer including breast cancer, colon cancer and prostate cancer.

Omega-3 also helps to improve your immune system to protect you from organisms that trigger colds, flu, allergies and fever.

5. It helps to improve mental health.

Omega-3 is known as a brain booster or brain food which helps to enhance your mental health and improve your ability to concentrate.  It is also believed to play a role in preventing Alzheimer's disease.

These are some of the known health benefits of omega-3 fatty acids. As a word of caution, you should take note that excessive intake of these substances can cause bloating and nausea.  You should avoid complications by taking omega-3 in moderation.
