Barry Sears - Mythologies of Fish Oil drsears.com/overview

using a 2:1 ratio of EPA and DHA provides the best clinical benefits as it ensures there will be adequate levels of both EPA and DHA.

What is the correct ratio of EPA to DHA that will provide maximum health benefits?

What is important is not the ratio of EPA and DHA in a supplement, but the ratio of AA/EPA in the blood. The AA/EPA ratio provides insight into the potential balance of the initiation of inflammation and its eventual resolution. The ideal AA/EPA ratio is between 1.5 and 3 as found in the Japanese population. For comparison, the AA/EPA ratio in the American population is 18. The higher the AA/EPA ratio, the less likely you are to have sufficient ability to resolve inflammation therefore creating chronic low-level inflammation that is the underlying cause of virtually all chronic disease. DHA levels will always be higher than EPA levels in the blood because of the continuing metabolism of EPA into DHA. I have found that using a 2:1 ratio of EPA and DHA provides the best clinical benefits as it ensures there will be adequate levels of both EPA and DHA. You need them both because they have different functions.

High-dose Omega-3 Fatty Acids

It is often difficult to obtain adequate levels of omega-3 fatty acids (EPA and DHA) that are the molecular building blocks to produce a specialized group of hormones known as resolvins. Resolvins are critical to the resolution of inflammation. Without adequate levels of these omega-3 fatty acids in the blood, it is impossible to make adequate levels of resolvins to return the body back to equilibrium after the initiation of inflammation. If the initiation phase of inflammation is too strong or the resolution phase is too weak, the result is chronic cellular inflammation. To achieve adequate levels of resolvin formation, a healthy person will require a minimum of 2.5 grams per day of EPA and DHA. For those with an existing chronic inflammatory disease, the levels of EPA and DHA required can be considerably higher to increase the resolution of existing cellular inflammation.

SPECIAL TOPICS » The Omegas (3, 6, 9) » High dose (1800 mg/day) EPA (fish oil) Regenerates HDL Function heartlifetalk.com/forums/

Recent research (2014) confirms what Dr. Barry Sears has long recommended. In this study, high dose (1800 mg/day) EPA was shown to be efficiently incorporated into HDL particles and improve HDL function and promotes cholesterol efflux from macrophages. I have long taken EPA:DHA at 2:1 ratio or 2660 mg EPA: 1300 mg DHA for total of about 4000 mg/day based on Dr. Barry Sears recommendation to control inflammation. This is close to my heart (no pun intended) since I am sure it was a significant factor in regression. This was part of a different approach I examined to prevent the genesis of atherosclerosis, rather than what most on other sites promoted (calcification focus). With 2:1 EPA:DHA fish oil and increased oleic acid (EVOO, omega-9), it reduces the amount of arachidonic acid in LDL particles that causes oxidization of LDL particles. So, it is good to know that there are HDL "regeneration" benefits to EPA's anti-inflammatory properties. The best source of information on O3, O6, and inflammation is Dr. Barry Sears (books and website):

One of the highest concentrations of omega-3s

Viva Naturals Omega-3 Fish Oil gives you 2,000 mg of omega-3s, 1,400 mg of EPA and 480 mg of DHA per serving. That’s 3x more than many leading omega 3 supplements (to get the same amount from some others, you’d have to take 4-6 pills a day). So it’s a potent, convenient way to get the benefits of fish oil pills you’re looking for, like heart and brain support.

Easy to absorb

Our fish oil delivers its omega-3s in triglyceride form, shown to be better absorbed than another form called ethyl esters. They’re easy-to-swallow softgels, too. So when it comes to helping you make the most of omega-3s, we’ve got you covered.

Unique extraction method cuts fishy burps

No one wants to deal with fishy burps or aftertaste, so we cut the chance through a method called supercritical extraction. It’s just a fancy way of saying that we separate out the omega-3s using carbon dioxide, rather than heat or harsh chemicals. This starves any bacteria hanging around that would need oxygen to survive, and strips away toxins and heavy metals.

IFOS 5-Star certified pure

We only use small fish (like anchovies, known to have fewer toxins at the start). They’re caught from the highly-regulated coastal waters of Peru using sustainable fishing practices. To help you feel great about your choice, each batch is IFOS 5-Star certified, meeting the highest international standards for purity and potency.
