Omega-3 fatty acids docosahexaenoic acid (DHA) and eicosapentaenoic acid (EPA) have been proven to support the body’s natural anti-inflammatory response, support cognitive function, and promote muscle growth. The problem is that the most common sources of EPA / DHA are fish oils that are poorly sourced and processed. Typically they’re low potency, contaminated, and/or oxidized.

Natural Stacks™ Krill Oil uses only sustainably harvested krill from the pristine Antarctic ocean. It’s immediately cold-pressed while still on board the vessel to preserve the biological benefits of the krill. Then it goes through a proprietary purification process and is lab tested to ensure that the krill oil has absolutely zero toxins, heavy metals, or other impurities.

Krill oil is superior to fish oil because the EPA and DHA omega-3 fatty acids in krill are bonded to cell-building phospholipids. This give krill oil significantly greater bio-absorption than fish oil. Also krill oil contains natural antioxidants including vitamin A, and vitamin E, and astaxanthin.

Optimal EPA / DHA Ratio

Our krill oil complex is formulated to outperform any other marine oil product on the market. We used small amount of Friend Of The Sea-certified tuna oil to increase the ratio of DHA to EPA, because DHA is the primary structural component of the brain.

DHA is essential for neurological development and function, while EPA can influence mood. They’re both anti-inflammatory and have complementary effects, but DHA appears to be more important for optimal performance because it’s the predominant fatty acid in the brain and nervous system.

Almost all wild caught fish has more DHA than EPA, yet most fish oil supplements on the market have more EPA than DHA because of their low grade sourcing techniques. Natural Stacks™ Krill Oil contains 160 mg DHA and 80 mg EPA. [1]

300 mcg of astaxanthin (7X more than most Krill Oil products)

Naturally found in krill, astaxanthin is thought to be the most powerful antioxidant found in nature. The only two main sources of this fat-soluble antioxidant are the microalgae that produce it (haematococcus pluvialis) and the sea creatures that consume the algae. It’s what gives salmon their pink color and is the driving force behind their incredible endurance.

Most krill oil products don’t say how much astaxanthin is in their product. Natural Stacks™ Krill Oil proudly offers 300mcg of the super-antioxidant in every serving.

Improved brain function

Last year, Japanese scientists examining 45 healthy elderly males concluded that “n-3 polyunsaturated fatty acids activate cognitive function in the elderly. This is especially the case with krill oil, in which the majority of n-3 polyunsaturated fatty acids are incorporated in phosphatidylcholine, causing it to be more effective”. [2]

A recent 7-week rodent study found “a robust antidepressant-like potential and beneficial cognitive effect of Krill Oil”. The results indicated that the “active components (EPA, HDA, and astaxanthin) in Krill Oil facilitate learning processes”. [3]

After a 35 days experiment on healthy people, it was discovered that “Omega-3 supplementation is associated with an improvement of attentional and physiological function, particularly those involving complex cortical processing”. [4]

Krill Oil as a Natural Anti-Inflammatory

A randomized, double blind, placebo controlled study on 90 patients clearly indicated that a daily dose of krill oil “significantly inhibits inflammation and reduces arthritic symptoms within a short treatment period of 7 and 14 days”. [5]

A rodent study evaluating to the impact of krill oil on arthritis found that “mice fed the krill oil diet demonstrated lower infiltration of inflammatory cells into the joint” and suggested that “krill oil may be a useful intervention strategy against the clinical and histopathological signs of inflammatory arthritis”. [6]

Krill Oil - superior to Fish Oil

A 2013 double blind, placebo-controlled study on 24 healthy volunteers found that “Krill oil consumption increased plasma n-3 PUFA concentration, including EPA and DHA, and reduced n-6:n-3 ratios compared with fish oil”. [7]

In a recent double-blind crossover trial comparing krill oil with fish oil demonstrated that “the highest incorporation of EPA+DHA into plasma phospholipid was provoked by krill oil”. Researchers found an “unexpected high content of free EPA and DHA in krill oil, which might have a significant influence on the availability of EPA+DHA from krill oil”. [8]

A study comparing krill oil with fish (menhaden) oil discovered that “when expressed per mg of EPA or DHA consumed there was a trend toward a greater increase in plasma EPA and DHA with krill oil”. [9]
