Essential Fatty Acids, or EFAs, are considered "essential fats" because they are required for good health but cannot be produced by our bodies. Research has shown that in order to foster good health and prevent deficiency, EFAs must be consumed daily. Satisfying the daily recommendation of EFAs through diet has become difficult due to the growing concern of environmental toxins in fish. Additionally, other factors inhibit the absorption of essential fats such as poor diets, alcohol consumption, aging, low levels of key vitamins and minerals, and certain medications. Research shows that the safest and most reliable source of Omega-3 fats is a high quality fish oil supplement. This means a supplement that is fresh, molecularly distilled, and guaranteed pure and free of environmental contaminants. We carry Nordic Naturals fish oil supplements in both adult and child strengths because they guarantee their purity and quality.
