Benefits of Both Krill and Fish Oil
Eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) are two omega 3s fatty acids found in fatty fish like salmon and crustaceans like krill. Scientists believe EPA and DHA give cell membranes a healthy structure, thus facilitating fluid and nutrient retention and flushing out of waste. There are certain organs in the body where EPA and DHA have been observed to have specific benefits.
Both epidemiological and clinical trials suggest that omega-3 fatty acids support cardiovascular health. The American Heart Association and the Mayo Clinic recommend eating fatty fish at least twice a week, but for those who cannot manage this for any reason, supplementation is recommended.
EPA and DHA are found abundantly in eye tissue, particularly in the ocular tissue. Both are known to support tear production and maintain fluidity in the membranes of the eye. When EPA and DHA are combined with micronutrients such as lutein/zeaxanthin, vitamin C, vitamin E, and zinc they exhibit a positive effect on vision protecting it against damage from sun, light, oxygen and age.1-2
Bones and Joints
Many different studies show that both EPA and DHA may help to support bone and joint health. Some studies have shown that taking omega-3 capsules regularly may help support joint comfort.3
There are significant amounts of DHA found in the brain’s neuron membrane phospholipids which is why DHA is thought to play a role in cognitive health. Scientists believe DHA may play a role in facilitating the transmission of nerve signals thereby helping in the proper functioning of the nervous system.4
Krill or Fish: What’s it to Be?
Krill sales were up in the natural channels in 2014 accounting for 12 percent of the total omega-3 supplement sales. Should you add a krill supplement to your product line? Is there a vast difference between krill and fish oil? Will your customers gain more benefits from taking krill capsules than fish oil capsules? Is it more expensive to manufacture krill oil capsules than fish oil capsules? Here’s some information.
Differences in Krill and Fish Oil5
• Krill oil is extracted from crustacean shellfish that live in the Antarctic Ocean.
Fish oil is extracted from fatty fish like cod and salmon found in the ocean.
• Because krill is extracted from fish found in waters that are less contaminated kill oil may be a more purified product.
Contamination is often a concern with fish oils, though fish oil extracted from the waters around Alaska or higher up may have the same pure properties.
• Fish oil comes in fat-soluble triglyceride form consisting of three parallel strings of fat, namely EPA, DHA, and omega 6.
Krill oil comes in water-soluble phospholipid form consisting of two fatty acids on one side and other health-friendly compounds on the other side such astaxanthin and choline.
• Fish oil yields more fat per pound than krill.
Do either have an advantage over the other?
Advantage of krill
•The water-soluble phospholipid form of krill is believed to allow for faster absorption in the body. Because krill oil is more quickly absorbed by the body it is argued that smaller amounts are required, but this theory has not been proven.6It can also be argued that faster bioavailability is an inconsequential consideration since the time factor is not critical. The critical factor is absorption of these healthy nutrients by the body and the omega-3s of both krill and fish oil are efficiently absorbed by the body.
• Krill oil contains less omega-6 fatty acids than fish oil. Omega-6 is the bad fat to be avoided. In contrast krill offers compound with health-promoting benefits. Astaxanthin is a neuron-protecting antioxidant and choline is a neuron-transmitter building block.
• Finally, in terms of sustainability, krill are deep-water, marine planktons abundantly available on ocean beds, a seemingly unending harvest. Fish oil is obtained from fatty fish like cod or salmon.
Advantage of fish oil
• Krill oil is generally more expensive than fish oil because the process to procure krill oil is more expensive. Fish oil generally takes about 3 to 4 days to decompose allowing a longer time for processing. In contrast, krill gets decomposed within 2 to 3 hours. Because krill has to be transported live to the manufacturing unit or frozen on harvesting, the entire process becomes a lot more expensive.
• As of now, more extensive research has been done on fish oil than krill.
Info for Manufactures & Business Owners
Both krill and fish are great sources of omega-3 fatty acids. Supplement business owners might want to consider offering both varieties to their customers. Partner with a GMP-certified supplement manufacturer, like NutraScience Labs, who can help you produce omega-3 capsules that contain fish oil that is pure, fresh and in a form that has a higher bio-absorption rate.
