Here’s a comparison of OmegaRx to krill oil.
Bottom line; OmegaRx has the same bio-availability, higher levels of purity, is cheaper per gram of EPA/DHA, and it’s highly sustainable placing much less burden on the ecosystem than krill. Details below.
Absorption of omega 3’s, whether in the triglyceride form, phospholipids (krill) or ethyl esters (OmegaRx), has been debated for years. Initially, the absorption of triglycerides and phospholipids is greater within the first 24 hours, however, after 48 hours the plasma concentrations of EPA and DHA are similar.
Bio-availability and Oxidation:
This study indicates that Krill is no more bio-available than (menhaden) fish oil: http://www.ncbi.nlm.nih.gov/pubmed/...dinalpos=2
While astaxanthin helps to prevent rancidity our “proprietary antioxidant blend” achieves the same benefits. Also consider the capsules are the most effective in protecting fatty acids from oxidation. The liquid when returned to the freezer will minimize oxidation. Dr. Sears has performed internal studies that demonstrate very little oxidation with the liquid fish oils during proper handling. Oxidation during shipping is not a concern as the products have been packed using a nitrogen flush removing oxygen from the bottle. A high doses (over 5g/d or 8 OmegaRx capsules) Dr. Sears suggests supplementing with a aloe vera based polyphenol product such as Sea Health Plus. This enhances it’s digestion and absorption.
It’s important to note that Zone Labs has all their fish oils independently tested for contaminants and oxidation levels. See: http://www.ifosprogram.com/files/Zo...001594.pdf
– note Category 3 Stability.
Unfortunately, all waters and therefore all sea life has been exposed to global pollution. It’s interesting to note that as a phospholipid krill oil cannot be purified or concentrated like ethyl esters. Demand that your krill oil has been analyzed by an independent 3rd. party and posted for everyone to review.
This study shows that Antarctic Krill (and other species) do show contamination: http://www.sciencedirect.com/scienc...e7e184b6Co
Neptune Krill Oil:
2 caps of Neptune = 150mg. of EPA & 90mg. of DHA. One capsule of Dr. Sears' OmegaRx = 400mg. EPA & 200mg. of DHA. Dr. Sears recommends 2,500mg. of EPA + DHA per day. That's what our grandparents consumed when they took 1 Tbls. of cod liver oil per day. This figure is also supported in the research literature. To supplement with 2,500mg. of EPA/DHA you need to take 4 OmegaRx or 20 Nepture Krill Oil. A 60 cap bottle is a 3 day supply. Buyer beware! Cost per 1,000mg. of EPA and DHA - OmegaRx = .58 compared to Neptune Krill at more than $3.00.
The Marine Stewardship Council has certified Antarctic krill. However, this site claims that the Antarctic krill fishery is not sustainable. See: http://www.krillcount.org/
Our product manufacturers are varied and the fish are sourced from a number of different locations. All are aware of environment sustainability and concern for the world's sea life. A number of our suppliers have been awarded "The Friends of the Sea" certification or are participating in similar programs. See: http://www.friendofthesea.org/news.php?viewStory
