KRILL OIL vs FISH OIL: Which Omega 3 Supplement Is Better (IS IT SAFE)
A Comparison of Krill and Fish Oils: Is One Better Than the Other?
Essential Fatty Acids
Why do people take fish oil or krill oil? Because both contain Essential Fatty Acids (or EFAs). EFAs are long-chain polyunsaturated fats that are "essential" because our bodies do not manufacture them, and they must be obtained from outside sources. The two main EFAs are Omega 3s and Omega 6s.
A healthy balance of EFAs is needed for healthy hormone production and thyroid function; for cell membranes; for brain function; for cardiovascular health (think cholesterol and triglycerides); for inflammation reduction; and for healthy skin and hair ... to name a few.
The typical Western diet has an overabundance of Omega 6s. They are found in things like highly processed corn oil, soybean oil, sunflower oil, and nuts and seeds. These foods, especially the oils, are found in just about any packaged, convenience food. There is no lack of Omega 6s in most people's diets.
The recommended ratio of Omega 6 to Omega 3 is 2:1. The American diet has more like a 10:1 ratio or even higher. A diet high in Omega 6s is directly attributed to inflammation and disease.
To balance out the high consumption of Omega 6s, it is important to get adequate amounts of Omega 3s. These are much less prevalent in the Western diet. In foods, Omega 3s are found largely in seafood, and to a lesser extent, in foods like flax seed, hemp, chia, and walnuts. Many choose to use supplements to gain enough essential Omega 3s, however.
The important forms of Omega 3 are EPA and DHA. These are ONLY found in fish and seafood (and marine algae). The form of Omega 3s in nuts and seeds is ALA, which must be converted in the body to become EPA and DHA. But this doesn't happen easily or as effectively.
So let's look at a couple of the supplements that contain biologically-ready forms of EPA and DHA: fish oil and krill oil.
