Q: I’ve heard a lot about fish oil? Is it something I should take?

A: Fish oils contain omega-3 essential fatty acids which help to reduce blood viscosity, increase good cholesterol (HDL) and lower triglycerides. Essential fatty acids cannot be made by the human body but are ‘essential’ for normal metabolism. Therefore, we must acquire them in our diet. Omega-3 fatty acids are often lacking in the modern diet, which is instead higher in omega-6 type fatty acids. Omega-6 fatty acids are found mostly in animal products and contribute to the body’s inflammatory response, vital for our immune system. The problem is not the omega-6 fatty acids, but rather that our diet provides us with too much omega-6 and not enough omega-3. The idea behind supplementing with fish oil is to provide the body with a healthy amount of omega-3 oils, and to create a more appropriate balance between omega 6 and 3 fatty acids in the body. Because fish oils are so beneficial in this aspect, they are an appropriate supplement for many people.

If you are vegetarian, vegan or opposed to animal supplements, you can also consider other oils that contain healthy amounts of omega 3 oils. Fish oils are often the first choice because they provide the greatest amount of omega 3 oils per serving. There are, however, many other non-animal sources of omega 3 fatty acids including flax seeds, hemp, canola, walnut, pumpkins, soy, algae, and purslane.

Talk to your Naturopathic Physician about whether a fish oil supplement is a good choice for you and what to look for in selecting a supplement. It is important to read all labels and look for certified products tested for Mercury and other contaminants and is guaranteed to be shelf-stable (to not turn rancid).
