You can obtain plentiful omega-3 fatty acids from foods such as walnuts, salmon and other cold water fish or take a krill oil, fish oil, or flaxseed oil supplement to obtain additional fatty acids.
Fish oil, krill oil, and flaxseed oil supplements all provide essential fatty acids, with flaxseed oil capsules a plant-based source for vegans and vegetarians.
If you are considering fatty acid supplementation but are concerned about taking fish oil, krill oil might offer a good alternative with the added benefit of antioxidants and readily-absorbed fatty acids.
For more information about the benefits of krill oil vs. fish oil, check out Everest Nutrition's comparison page, or speak to your doctor or pharmacist about what kind of supplement is best for you.
In addition to being the richest and most bioavailable source of Omega 3s, krill oil will not cause any of the side effects associated with fish oil such as fish burp, gas or fish breath.
