No doubt you have heard about the importance of omega-3. You probably know you should be taking fish oil supplements, but most people don’t know what exactly fish oil does or why they should take it.
More importantly, are there any risks or side effects when taking fish oil? I hope this article will clear up everything for you.
What Are Fish Oil Supplements?
EFAs (essential fatty acids) are long chain, polyunsaturated fatty acids. Despite their essential nature, your body is unable to produce them in house. Therefore we need to get them from the foods we eat every day.
Polyunsaturated fatty acids are omega-3 (alpha-linolenic acid) and omega-6 (linoleic acid). There is also omega-9 but it’s not essential so therefore we only really need to worry about the first two.
Essential fatty acids have a number of roles within the body including:
- Gives us healthy hair
- Promoting healthy cell membrane formation
- Take care of thyroid and adrenal gland activity
- They help with production of many hormones
- Are responsible for brain development
- Breaking down cholesterol
When these are consumed, they’re broken down into EPA (eicosapentaenoic acid) and DHA (docosahexaenoic acid). EPA and DHA are responsible for a number of bodily functions and offer many physical and mental health benefits.
Where Does Fish Oil Come From?
Fish oil is sourced from either deep water farmed or wild caught, cold water, oily fish including:
- Albacore Tuna
The Dangers of Essential Fatty Acid Deficiency
Perhaps you’re wondering what happens if we don’t get enough of these essential nutrients? Believe it or not, if you’re deficient in omega-3 and omega-6, it can lead to you losing your hair, losing vision and even change your mental state.
A significant amount of research has also been done in the area of omega-3. Findings have shown that correct levels of EPA and DHA in the body can have positive effects on a number or chronic diseases and conditions such as cancer, cardiovascular disease, ADHD and depression.
Infact, most recently the US Food and Drug Administration (FDA)released a report announcing a qualified health claim that omega 3s, most specifically EPA and DHA, for reduced risk of coronary heart disease (CHD).

On occasion, there are some unpleasant, yet mild side effects experienced when using fish oil supplements including:

If the fishy taste really bothers you, yet you still want to the benefits of a supplement, try freezing the capsules. It won’t make them any harder to swallow since you take them whole, but the taste will decrease significantly. They won’t melt and release their pungent fluid until further down your digestive tract.

Fish Oil Interactions
Every time I recommend a health product or dietary supplement, I make sure to mention that if you have an ongoing illness or take prescription medicines, check with your doctor before starting. Fish oil is no exception.
Fish oil can interact with blood thinning medicines such as warfarin. If you have a clotting disorder, you shouldn’t take a fish oil supplement unless directed by your physician. It can thin the blood and increase bleeding. (source)
Most importantly, it is crucial that you never exceed the dose of fish oil supplements stated in the directions of use. There is a tendency amongst the fitness community to up the dosage in order to help you achieve weight loss and fitness goals faster. This should never be done without the direction of a medical professional.
