The human body needs both plant and animal sources of omega-3 fats, but they are not interchangeable.
Plant-based omega-3 provides alpha linoleic acid (ALA), which the body inefficiently converts to EPA and poorly converts to DHA. Plant-based sources of omega-3 include flaxseed, walnuts, pumpkin seeds and chia seeds. These help to boost ones overall ALA intake.
Fish and marine oil supplements are a direct source of EPA and DHA.
EPA and DHA are essential in digestion, blood clotting, memory, learning and functions of cell receptors. These from ones diet. You may choose to increase your intake of wild-caught Alaskan salmon, mackerel, anchovies and herring to do so.
However, if these are not available, choose to use a krill oil supplement rather than fish oil. Since fatty acids are insoluble in water they need to be packaged in a type of lipoprotein to be transported within your blood. An unprocessed fish oil supplement is bound in triglycerides while krill oil is mostly bound in phospholipids.
It is the phospholipids in krill oil that make this form of omega-3 supplement easily bioavailable in the 1st 72 hours. As we consume fish oil, the liver must attach it to a phosphatidylcholine while krill already contains this substance, yet another reason krill oil demonstrates more efficient cellular uptake.
In addition to these advantages, fish oil has a higher likelihood of oxidative damage, making it less stable than most other supplements. In testing 54 of the best-selling supplements, 1 lab found 59.2% of the products had levels of omega-3 that varied by more than 10% of what was labeled on the bottle.
The testing also revealed 92.5% had measurable amounts of Mercury, known to damage the nervous system, digestive tract and immune system, as well as on the lungs, skin and kidneys, so…
