Thanks for your question. Unfortunately, it’s almost like asking if eating just an apple is sufficient, or if you should be eating other fruits as well. Krill Oil has a good variety of essential fatty acids (EFAs) in them, but it doesn’t have all of the EFAs and there are other sources that have different benefits that you might also want to consider.
Some EFA examples:
- Flax Seed Oil has Alpha Linolenic Acid (ALA), which Krill Oil does not, as well as more Linoleic Acid and Oleic Acid than Krill.
- Borage Oil has Gamma Linolenic Acid (GLA). Krill does not.
- Fish Oil has more EPA and DHA than Krill Oil has, and the list goes on...
However, while Krill Oil may have less of some of those nutrients, it does have more of a variety of those nutrients than the other EFA products mentioned (plus some that none of the other EFA products have).
This doesn’t mean that you must take a variety of other EFA products to get any benefits, but each source has their own unique benefits. Whether you take Krill Oil for the variety, Fish Oil for the higher amounts of EPA and DHA, Borage Oil for the hormone balance and skin benefits, or any other option, they are all good nutritional options for EFA supplementation.
