Dr. Oz and Omega-3 Supplements

I like Dr. Oz.

A lot.

But the popular TV doctor is off-target with his message on Omega 3 supplements.

To be fair, Dr. Mehmet Oz has done a lot for America’s health. He has a wonderful way of explaining complex medical symptoms and diagnoses to everyday TV watchers.

The problem with Dr. Oz and Omega 3 Supplements:

  • He favors DHA Omega-3 over EPA Omega-3. He actively instructs his followers to avoid EPA.
  • He believes EPA is not ‘really effective.’
  • He believes EPA can cause increased bleeding.

Avoiding EPA entirely may be harmful, especially to Americans and those eating western diets – I’ll explain why in just a minute.

It’s true that DHA and EPA have slightly different roles in your body.

DHA is a STRUCTURAL Omega-3. That means the body uses it to build body parts, especially in fetus and children.

EPA on the other hand, acts as a ‘lubricant.’ It works through all stages of life to reduce inflammation and several diseases associated with it.

DHA is critical for pregnant women and children. Most of the Omega-3 in the brain, eyes, heart and other very active tissues is DHA.

DHA must be consumed by pregnant women to ensure proper development of the fetus. Research has shown that children of women who avoided fish during pregnancy had much lower IQ points than women who ate fish and consumed Omega-3 supplements during pregnancy.

Well, my argument with Dr. Oz is not with DHA and pregnancy, so let’s take that off the table.

My issue with his advice is the avoidance of EPA, an entire fatty acid!

All Omega-3 supplements should ideally provide BOTH DHA and EPA. A prenatal omega-3 supplement could have very high DHA and low EPA levels. That’s OK.

And an anti-inflammatory or anti-depressant focused Omega-3 supplement could have a high EPA to DHA ratio.

Looking at Nature for Answers

Most fish oils naturally have more EPA than DHA. More than 90% of all fish oil sold in the world contains more EPA than DHA.

Salmon has roughly equal parts EPA and DHA. Tuna oil is the rare exception with more DHA.

Looking at Science for Answers

In the last decade, a lot of research has focused on the separate roles of DHA versus EPA. Here are some of the findings:

  • EPA key role in the body is to keep pathological inflammation under control
  • EPA Omega-3 controls disease by reducing inflammation, after all, diabetes, obesity, arthritis are all inflammation related diseases
  • EPA regulates your immune responses
  • EPA protects the heart, brain and nervous system
  • EPA must be constantly provided to the body because it is found in EVERY CELL in your body

Recent clinical trials show:

  • EPA has been shown to moderate the onset and symptoms of Alzherimer’s
  • EPA has been shown to moderate autoimmune disorders
  • EPA can reduce symptoms of mood disorders like depression and schizophrenia
  • EPA has some of the best evidence for reducing cardiovascular disease

It’s no wonder that EPA is being looked at as a new active pharmaceutical ingredient.

EPA-based Rx drugs on the way

High-purity EPA concentrates are being investigated as new ‘drugs’ by several pharmaceutical companies. Epadel and Miraxion are two EPA-based drugs in development.

Omthera Pharmaceuticals is entering Phase III Clinical Testing with Epanova, its EPA-based drug. Pfizer recently spent $800 million to conduct Phase III testing of a new drug.

May be it is a little cheaper to develop a new drug based on EPA fish oil, but are all these pharmaceutical companies wrong?

Phase I Clinical Trials test for safety.
Phase II Clinical Trials prove efficacy.
Phase III confirms efficacy and dosage.

Why would these pharma companies spend millions of dollars on Phase III testing an EPA-based drug if EPA was ineffective?

It’s not that EPA is ineffective. But rather DHA has a undesirable side effect of raising LDL (Bad) cholesterol.

Yet Another EPA-only Drug

Amarin’s new Vascepa drug was recently introduced to the market – talk to your doctor. The clinical trials for this drug were very positive. Vascepa is a triglyceride-reducing drug that’s 96% EPA Omega-3 from fish oil. Amarin specifically chose to leave out DHA from their formula because of its LDL-raising effects. Read more here.

Percent Change in LDL Cholesterol after 600 mg each of EPA, DHA or Placebo (Olive oil)

In this study, 110 healthy people were given olive oil or EPA or DHA for 6 weeks. 600 mg of DHA Omega-3 showed about 14% increase in LDL Cholesterol.

DHA Omega-3 raises LDL (bad) cholesterol by about 14%

EPA helps with Depression. DHA does not.

More than a dozen clinical trials have used EPA exclusively to show that it can treat depression as well as prescription medications.

The landmark Oxford-Durham trials used high-EPA fish oil to reduce childhood learning and behavioral problems.

Scientific Proof:

  1. American Journal of Psychiatry. 2003. 160:996-998 concluded that DHA was no more effective in treating major depression than placebo. See reference here. And read full study here.
  2. Schizophrenia Research. 2001. 49(3): 243-251 showed that EPA was superior to DHA in treating schizophrenia. See reference here.
  3. Archives of General Psychiatry. 2002. 59: 913-919 showed that adding EPA to the regimen of prescription drugs yielded better results than drugs alone. See reference here.
  4. Journal of American College of Nutrition. 2009 Oct;28(5):525-42. says EPA but not DHA appears to be responsible for the efficacy of omega-3 long chain polyunsaturated fatty acid supplementation in depression: evidence from a meta-analysis of randomized controlled trials.  See reference here.

EPA is for more than just mood health

Before you think EPA’s role is only mood related, let me point you to the JELIS Study (Japan EPA Lipid Intervention Study), the first primary intervention trial with an Omega-3 and the first (of many) to show a benefit with EPA alone (as opposed to EPA + DHA). EPA showed a remarkable reduction in ‘cardiovascular events’ in almost 19,000 patients. And remember, the patients were Japanese, a population that already gets a lot of Omega-3 in from the regular diet.

Another study from the University of Oslo, Norway concluded that EPA, and not DHA, is primarily responsible for the triglyceride-lowering effect of fish oil. Source: Rambor et al. Eicosapentaenoic acid is primarily responsible for hypotriglyceridemic effect of fish oil in humans.

Natural Conversion of DHA to EPA and Back

Our bodies are capable of converting DHA to EPA using enzymes, but it is not an efficient conversion. Conversion of EPA to DHA is far less efficient or even completely absent due to the requirement of an elongase enzyme followed by beta-oxidation. There are several metabolic factors that influence these elongation and retroconversion steps. Sources: Hansen et al. Lipids. 1998 Feb;33(2):131-8, Grimsgaard et al. Am J Clin Nutr. 1997 Sep;66(3):649-59. Read full paper here.
EPA Omega-3 Supplements
A study conducted at the University of Guelph by the renowned Dr. Bruce Holub estimates that only 9.4% of DHA is retroconverted into EPA. Source: Conquer & Holub. Dietary docosahexaenoic acid as a source of eicosapentaenoic acid in vegetarians and omnivores. Lipids. 1997 Mar;32(3):341-5.

The same authors conducted a similar study, this time, using Algae-DHA. Again, they found that 11 to 12% of DHA was retroconverted to EPA. Source: Conquer JA, Holub BJ. Supplementation with an algae source of docosahexaenoic acid increases (n-3) fatty acid status and alters selected risk factors for heart disease in vegetarian subjects. J Nutr. 1996 Dec;126(12):3032-9. Read full article here.

Both these studies suggest that if you took just DHA, only a tenth of it would be converted to EPA. That’s not enough if you are seeking benefits that only EPA seems to provide, such as mood support.

The new science of Nutrigenomics says that foods are messengers. They convey messages to our body. And tell it what to do – gene expression. A study conducted at the University of Bergen in Norway says that (at least in rats), EPA and not DHA activates the genes that helps reduce triglycerides. Source: Willumsen et al. Lipids. 1996 Jun;31(6):579-92.

It is far more efficient to just take preformed EPA and DHA together.

The American Diet NEEDS EPA Fish Oil

Our bodies are designed to thrive on equal parts Omega-3 and Omega-6.

Unfortunately, due to the presence of omega-6-rich corn oil and soy (vegetable) oil in almost all our foods, we now eat 25, 30 or even 50 times more Omega-6 than Omega-3.

This is a formula for disaster. Why? Because the byproducts of Omega-6 (ARA) cause inflammation in tissues and organs. This contributes to several diseases like obesity, diabetes, high triglycerides, heart disease and depression.

Given our pro-inflammation diet, we MUST have EPA to ‘cool’ down the inflammation. EPA supplementation alone is not the answer – this new study suggests reducing Omega-6 works slightly better. Source: Wiet et al. Lipids. 2010 Aug;45(8): 683-92.

Another famous doctor, Dr. Barry Sears, outlined exactly how and when you’d get sick by looking at your ARA to EPA ratio. See his book, The Omega Rx Zone. Harper Collins. Check out page 95.

With the growing mountain of new scientific evidence supporting the benefits of EPA, I’m finding it very hard to believe that EPA is ‘not really effective.’

OK, how about EPA and excessive bleeding, you say?

Well, the American Journal of Cardiology just published a paper from scientists at Drexel University that says high-dose fish oil by itself or even if combined with aspirin ‘is safe and does not increase risk of bleeding.’

Again, the bleeding argument is old.

When Jorn Dyerberg, the ‘father’ of Omega-3 first discovered that Eskimos were protected from heart diseases from their high Omega-3 levels, he also noticed increased incidences of nosebleeds.

What most people (including Dr. Oz, I presume) don’t know is that the average Eskimo (or Inuit) consumes 13,000 mg of Omega-3. Americans average 100 mg.

You’d have to eat 43 (yes forty three!) retail-grade fish oil pills every day for a long time to equal Eskimos in nosebleeds.

Can you say the same thing about the safety of Tylenol, Aspirin or any of the other OTC drugs whose safety we take for granted?

Dr. Oz and Algae-based Omega-3 Supplements

He claims that algae-derived DHA give you “DHA’s perks without the fishy burps that fish oil capsules may cause.”


DHA, regardless of where it comes from, is extremely sensitive to oxygen, light, heat and metals. All these things cause oxidation (rancidity.) And oxidation causes DHA (or EPA) to smell.

It does not matter if the DHA (or EPA) comes from fish or algae. If it is poorly handled or stored, it will spoil. It will stink and it will make you burp. Period.
Algae DHA Omega-3 supplement
If you don’t believe it, go to Walmart and buy a Spring Valley DHA 900 mg made with algae-DHA. Or talk to my wife who took one pill and gagged.

Algae-based DHA is neither more nor less susceptible to rancidity than fish oil based Omega-3 supplements.

Dr. Michael Roizen, Dr. Oz’s long-time business partner and co-author, is/was a scientific and medical consultant to Martek Biosciences Corporation (DSM), the algae DHA company.

Algae is a great source of DHA. After all, that’s where fish get it from! In the not-too-distant future, we will run out of fish to feed our expanding population – so algae-sourced DHA & EPA is the sustainable future of Omega-3 supplements. But for now, making EPA from algae is still very tricky.

Doctor Oz, it hurts your TV audience when you disparage EPA. That bugs me. May be it bugs me more because I’m associated with OmegaVia, a high-EPA formula. But I don’t tell people to avoid DHA! On the contrary, I encourage it.

But I see recently that you’ve been warming up to EPA.

What Other Experts are Saying…

In the last week, I spoke to three doctors about this and got four different opinions.

But here are a few public opinions:

“I was surprised to see him miss the all-important Omega-3 fat known as ‘EPA’. EPA and DHA are similar; they are found together in foods and work together in the body. Would you choose to use your left hand without your right hand when they work better together?”

“…when it came to recommending omega-3 fats, known to be vital to cardiac health, Dr. Oz, once again, gave recommendations only for DHA, and not EPA. DHA is one of the 2 functional omega-3 fats, but some of the best evidence for prevention of heart disease is attributed to EPA and how EPA works in the body. I sure would like to discuss this with Dr. Oz, and welcome the opportunity to show him the scientific evidence.”

– Gretchen Vannice, Expert Nutrition Researcher and Dietitian, in her blogs titled:
Why is Dr. Oz missing EPA?
Oh, no! Dr. Oz

Diabetes: Dr. Oz, How Did You Get It So Wrong?

Dr. Oz Gets It Wrong On Fish And Mercury and National Fisheries Institute weighs in as well.

Dr. Sears, a Doc of a Different Stripe

Dr. Sears on EPA fish oil
Dr. Barry Sears, founder and chairman of Zone Labs, has said the key to benefits from consumption of fish or fish oil supplements are due to the EPA, not the DHA.

“Because the brain contains relatively low amounts of EPA compared to DHA, it has always been assumed that it was the DHA that gave rise to these benefits. In fact, an entire industry was built on the concept of supplementing infant formulas with DHA would improve the neurological health of both the mother and child. Of course, no one ever tested this hypothesis until now.”

The October issue of the Journal of the American Medical Association published an article looking at the dietary supplementation with a fish oil supplement exceptionally high in DHA and very low in EPA. Unfortunately, the results were the opposite of the prevailing thoughts. In fact, the researchers found no cognitive benefits for either the mother or child. This calls into question why we are supplementing infant formulas with DHA.

The answer is that benefits of fish consumption or fish oil supplementation are due to the EPA, not the DHA.”

Omega-3 supplements


Overall, I think, Dr. Oz has done a tremendous job informing and educating. I respect and look up to him for that. But I see that he is warming up to EPA, noting in a recent YouDocs newspaper column that “EPA is getting its due.”

Nutritionally, America is SO off-balance, that any national awareness Dr. Oz brings to Omega-3 (DHA or EPA), will improve our well-being and reduce our health care costs drastically.

  1. Dr OZ approach backed by science and Dr Doughman review. We’re looking to speak the truth from a metabolism point of view about “Directional Omega-3 Metabolism”.

    Source-Omega Reviews DHA Retroconversion Metabolic Dosing Using Algae Oil Omega-3s as a Fish Oil Sub

    “What all the human omega-3 red blood cell data independently points out is that DHA is always 3 to 8 fold more abundant than EPA in human blood and tissues, even after prolonged intake of high doses of predominantly EPA” Dr Doughman.

    Source-Omega revealed their discussion, forwarding that composition studies in 1978 proved DHA is naturally the most abundant omega-3 form in the human body and blood in comparison to EPA levels in untreated individuals (Sanders et al., 1978). In 1986, a review by Herold and Kinsella of human volunteers treated with fish oil omega-3s revealed higher DHA fatty acid composition in red blood cells compared to EPA, despite high EPA intake (Herold and Kinsella, 1986).

    Fish oils have been an abundant source of EPA, so fewer studies may have taken into consideration that DHA is the most abundant omega-3 long chain fatty acid because EPA was the main omega-3 given as a fish oil treatment.

    When Conquer and Holub published on algae oil DHA treatment of human subjects in 1996, a detailed double-blind randomized placebo controlled study, the authors found blood omega-3 parameters consistent with humans taking high dosages of fish oil (Conquer and Holub, 1996). The 1996 study showed RBC increases in both DHA and EPA through accretion of DHA and retroconversion of DHA. Other metabolism studies have shown DHA is also a template that will provide all the C22, C20, and C18 omega-3s needed in the body through retroconversion, say Source-Omega scientists.

    DHA delivers saturation levels of omega-3s to RBC membranes when the DHA dosage for adult clinical use begins with 1.0 g to 1.2 g DHA per day, which company results, or previous published studies show can provide saturation levels of omega-3s within 90 days (Arterburn et al., 2008).

    The scientific literature shows high-dose DHA derived from microalgae lowers hypertriglyceridemia after 90 days of treatment, by up to 26 percent with at least 1 g DHA daily (reviewed by Ryan et al., 2009). With a safe, effective dosage range for any adult, the GRAS safety registration of algae oil and the dosage range have been positively ruled-upon, as such, by several international regulatory bodies.

    “The summary of these historical studies together suggest ‘directional omega-3 metabolism’, where fish oil is ‘uphill’ and algae oil is ‘downhill’. EPA intake leads to multistep synthesis to DHA with fish oil. DHA intake leads to a single step retroconversion to EPA with algae oil. The body knows how to balance its final levels from each direction, but ‘downhill’ appears more efficient at high omega-3 doses,” said Doughman.

    Each method then flows towards a somewhat pre-defined homeostatic balance of cellular and tissue specific omega-3 compositions, the data suggest.

  2. As a retired RN (from the days when medical opinion dictated that none of us needs vitamin supplements if we eat a “balanced diet”), — I applaud and concur with your take on Dr. Oz’s limited simplistic approach and his propensity for recommendations when he dares to believe he is thinking “outside of the box”,,,, yet in truth, he is only just beginning to peek through a pinhole in the box! Initially, I found Dr Oz interesting to watch, but for sometime now, I can’t listen to opinions without me literally arguing with the TV set. He consistently falls short of the “complete truth”. I actually pity his audience who often look to him as a God authority — & buy into all he says without question. Thank you for going deeper into the issue & explaining what poor Dr. Oz has so sadly missed in his conclusions!

    • Hi – thank you. I like Dr. Oz. I think he means well. I just don’t listen to him when it comes to nutrition or diet. Our medical schools don’t focus on nutrition, so most doctors miss the opportunity to realize that bad diets cause a lot of our chronic diseases. And that good nutrition can prevent them. The problem is that most doctors think good nutrition = low-fat and plenty of whole grains!

  3. I have taken Fish Oil [ omega 3,6,9 – derived from Fish oil, flaxseed, and borage oil] which contains both DHA, EPA and ALA and have also taken DHA Alga -900 – to date I have experienced better results concerning memory retention, testosterone increase, lessened depression, lowered blood pressure, change in cholesterol, overall mood and better eye sight when using an Omega 3,6,9 1000mg twice/day than using only DHA at the same mg dosage.

    • Hi David – thanks for sharing. Everyone is different. There is one ingredient in the 3-6-9 pills that is not present in the DHA 900, namely EPA. It is possible that the EPA was doing the trick for you. EPA and not DHA helps with depression and mood. Certainly, as I mentioned above, DHA is critical. But so is EPA. If that’s what you need, then algae oil will not give you what you need. You body converts about 10% of DHA to EPA but that conversion is inefficient. And you certainly don’t need any more Omega-6 or Omega-9 that what your diet already provides. My suggestion is to get an Omega-3 ONLY product. I think you’ll notice more of these benefits you’re looking for.
      – Vin Kutty

    • Hi Ursula – without a gallbladder, your liver has to work extra hard to digest fats. This is part of the reason why you are having issues with Omegas. You may want to try taking your fish oil with a meal that does not have as much fat. Or you may want to try taking krill oil – these have very little oil and Omegas…they may be easier to digest but they also come with very little Omegas. Hope this helps.
      – Vin Kutty

  4. I want to know what brand of omega 3 from algae is good for my 9 year old son and the right dosage per day. Thank you,

  5. makes on difference. DHA studies indicate that your body will make EPA from DHA. I suspect if you look it also makes DHA from EPA but I haven’t seen that in print yet. The really important questions are are we getting enough and how much is too much. Is it fresh clean and sustainable. After that it is just what is handy and affordable.

    • Hi – Yes, your body can convert DHA into EPA. This process if called retroconversion. But only about 10-12% or so is converted when DHA is present in good quantities. This is not enough. EPA can also be converted to DHA but this is much, much harder the other way around. This conversion rate is usually a percent or less. But you are absolutely correct in adding perspective to the discussion in suggesting that we get ‘enough.’ We don’t know the answer to ‘how much is too much’ yet. For most people, 2-3 grams or 2000-3000 mg of Omega-3 per day ought to be plenty.
      – Vin Kutty

  6. I can tell you from firsthand experience that EPA is extremely effective for depression and inflammation. And I mean EXTREMELY. perhaps not for everyone and not every type of depression but, after reading the omega-3 connection by Dr. Stohl, I immediately forced my girlfriend to start taking it. She resisted until she understood I couldnt take being with such a negative person anymore. I paid for the brand they use at Harvard. She took therapeutic amounts as per my instructions (she wouldnt read the book, naturally). The results were nothing short of miraculous. its worth noting she also had major physical pain that the fish oil, no doubt, improved greatly and this likely also had an effect on her depression so it may be less effective for those with no physical pain but, according to Harvard docs, it is very effective and it was for her too. (in case you were curious – I would be – she improved beyond my wildest expectations. so much so that she started to deny that it was the fish oil that was helping her but rather that it was her inner spiritual growth – a load of crap, obviously. not that she wasnt experiencing growth – I’m sure she was but the lifting of the wet blanket of depression and pain allowed that to happen and the fish oil was clearly responsible. the funny thing is that within days she started to grudginly admit the fish oil was helping. then a few days later “really helping”. within weeks she said “I havent felt this good in years”. and the whole time she had resisted the thought of taking it. so…….shocked and amazed (and intellectually fascinated by her behavior), I ended things as I couldnt take it anymore. some people have strong emotional needs or reasons for not feeling well or being a victim or always having something to complain about. But its incredible to see it happen with an intelligent person who experienced such incredible results. Anyway, EPA is critical!!!! great article! thank you!

    • Hi Allen – thanks for sharing that. Very good to hear. Depression is not just hard on the person going through it – those around them suffer too.

      Thanks again.
      – Vin Kutty

  7. An intelligent though ordinary person without specialized scientific training and knowledge has a difficult time coming to terms with all the conflicting claims about DHA, EPA, Omega 3s, 6s and 9s and so forth. One thing I do know, and you’ve alluded to it briefly, is that with so many fish being killed to make fish oil supplements, we are surely driving them to extinction. Algal oils might prove helpful when all the fish are gone, but then the algae, a food required by many marine organisms, also will be “gone” because humans think somehow any form of exploitation of other creatures or the environment is okay if it benefits humans. Now we are talking about products made from krill? These organisms are the essential food source for baleen whales, which consume incredible amounts of them every day. Now we humans decide to “harvest” krill for our benefit (screw the whales). Where is it all leading so that producers of nutrition products can enrich their bottom lines? Of course you don’t want to hear this, and I don’t blame you. In the future, none of these products will exist and probably in retrospect will be considered as primitive as we now consider cod liver oil. There has to be a better way that is good for humans, the environment and the other organisms with whom we share this very finite planet.

    • Hi Richard – great comment!

      Actually, I DO want to hear this! We SHOULD be talking about this!

      Food fish are in more dire (direr?) straits than fish used to make oil. Oil fish are still fairly abundant. But the weather patterns are so screwed up that they’ve not been able to catch oil fish (anchovy, sardine etc.) off the coast of Peru the last couple of years, which is where most oil fish come from. Peruvian fishery is not MSC certified sustainable. Wild fluctuations etc. So we switched to Alaskan fishery a year ago, which is Marine Stewardship Certified Sustainable. Sustainable oil is much more expensive and we ate the cost. It hurts our bottomline but it was the right thing to do.

      Algae oil is all from algae farmed in vats and pools. We don’t get algae from the ocean. This technology is still too expensive. It won’t become viable until fish oil gets too expensive – not too distant future.

      Krill oil – when people figure out how many of those pills they’ll need to take to make it work, they’ll stop taking it and the whales will have more to eat. Self-correcting problem.

      Again, thank you for bringing this up.

      – Vin Kutty

      • Thanks for your straightforward reply, Vin. I did realize after the fact that the algae in those supplements which you recommend for vegans is made in vats, not taken from the ocean. I’d like to tour such a factory, though. As for the krill oil thing being “self-correcting,” I’m not so sure; humans are a strange species, and most of the ones who have the money will spend it, regardless of the consequences if they think they (the dominant and most important species after all), will benefit. So many are just clueless as to immense suffering their habits cause to animals, or don’t want to be bothered.

        It’s nice that vegans are being seen as less freakish than in the past (partly I would assume, because they now represent a viable market), but why have we vegans chosen that path in the first place? It is because of the incredible dark side of our species, most of it anyway, that demands food and products we can live without, for convenience, taste, fashion and whatever, regardless of the incredibly cruel exploitation of animals involved. We do to them every day, by the billions, what we would consider criminally unethical if done to humans. Unfortunately, humans always have been addicted to causing suffering to other humans as well. Most people want to have their cheeseburgers in peace, and not be bothered by freaks like me, as we also think it’s okay to kill children with drones in countries like Afghanistan and Pakistan, as long as our children are not killed; but perhaps, some day we will evolve to be truly human and deserve the “wise” in our name homo sapiens. Be well,

        Richard D

  8. I am confused as to what I should take? I know fish oil is good for you and I try to eat salmon or some type of fish weekly but I would like to take a supplement but I do not know what to buy & how much in mg of EPA & DHA should I be taking so that my body absorbs the correct amount of each. I have a family history of alzhiemers, heart problems, & diabetes. I want to be proactive in keeping these health issues at bay.
    Please advise.
    Thank you

    • Hi Courtney – you should definitely talk an integrative physician if you are concerned about preventing Alzheimers and diabetes. Prevention is not something regular doctors and medical system does well. They mostly handle symptoms and cure AFTER you get the disease. If you want to prevent these diseases, talk to an integrative or preventive MD. Find them here: http://paleophysiciansnetwork.com

      Hint: if you’re worried about Alzheimer’s read Dr. Perlmutter book: http://drperlmutter.com/the-premise-of-grain-brain/ Interestingly, what prevent Alzheimers will also prevent diabetes, according to him.

      As for Omega-3, aim for about 1000 mg per day. Get a concentrated formula – something pharma grade. Don’t worry too much about mg EPA or DHA etc. First get the Omega-3 in you. As you learn more, you can switch brands and find one that is more ideal.

  9. Hi, Please let me know whether I can take Nordic Naturals,”Algae Omega”? It has (2 soft gels) EPA 180mg, and DHA 320 mg. Will this 2 capsule routine will help my Bad Cholesterol? I never had High cholesterol earlier but I got it recently, so will this supplement help me control my Overall Cholesterol? I have HDL 52. It is expensive also. One bottle with 120 soft gels cost $50.00. Please let me know. Thank you.

    • Hi Lalima – yes, it is a very good product. However, it will not change your cholesterol. It will lower your triglyceride, a much more predictive marker of heart health, if you take 3000 mg of Omega-3 or so per day.

  10. Hello!

    Please answer this question! Is it true that EPA and DHA compete with each other for binding sites in the cell membranes?

    I’ve suffered from tiredness/insomnia/depression since the summer of 2012. I wake up in the middle of the night, or too early in the morning, and I have problems focusing during the day (even when I’ve slept relatively much uninterrupted) , and I just don’t feel as happy. I’ve been trying taking Omega-3 with 60% EPA and 40% DHA for eleven weeks, and I guess it helps a little bit. However, supposedly DHA is good for insomnia (according to a recent study) and EPA is good for depression, so if they compete, which omega-3 should I take?

    Ps. English is my second language, so excuse me if I’ve not expressed myself well enough!


    • Hi Sebastian – there is some degree of ‘competition’ between EPA and DHA when it comes to depression. But for the most part, they are complimentary. You could always increase your ratio of EPA to DHA a little bit. And increase your daily dosage to 2000 mg of Omega-3. Beyond that, I suspect there are several dietary and lifestyle factors that will probably need to be addressed. I seriously doubt Omega-3 deficiency alone is the cause of your troubles. I suggest you look into a low-sugar, anti-inflammatory diet like Paleo or Zone. And take dramatic steps to reduce stress (exercise, yoga, meditation) and make sure you walk at least 10,000 steps a day. And get PLENTY of sunlight exposure in the summertime.

  11. Hi, can you recommend what brand name of omega 3 to get, there are so many in the market, it gets confusing. Thank you!

  12. Hi. What is the recommended dosage and ration of EPA -DHA? The prenatals I am taking contains 200mg of DHA but no EPA. I am considering taking the Nordic naturals algae omega which contains 180 mg EPA and 320 mg DHA. Do you think this is a good dosage? Thanks.

    • Hi Min – if you’re taking a prenatal, I assume you are pregnant. Congratulations. 200 mg of DHA per day is very low, especially during the third trimester, when your baby’s brain is growing fast. I would switch to the Nordic Natural products and take at least 2 or 3 of it per day…however, if you are pregnant, please work with your OB and make sure everything you take is OK with your doctor.
