Omega-3 to Omega-6 Ratio Experiment

Recommended Posts

In the last month or so I've started using Cronometer (before I used Myfitnesspall for a year) and with the new data available to me in Cronometer, I decided to drive my Omega-3 to Omega-6 ratio closer to 1:1 and see what happens in 6 months.

My main source of Omega-3 is unfortified brown flax meal of which I eat between 40 and 70 grams a day. I eat smaller amounts of chia seeds and steel cut oats (all organic, so not fortified). I also eat about 15-20 grams of walnuts and about 20 grams of "raw" cacao nibs every day. I've started eating mushrooms every day as well, in addition to legumes (Black Gram, since it has a great Omega-3 to Omega-6 ratio, lentils, quinoa, chick peas, occasionally black rice, etc.). I also eat a good amount of leafy greens, roots, broccoli sprouts and an apple or a pear almost every day.
My last test showed (I am in my late 50s):

Cholesterol: 170
LDL: 87
HDL: 73
Triglycerides: 54
HSCRP: 0.35 (this was a weird jump from 0.02 a year earlier, but the change doesn't appear significant).

My resting heart rate is 50-51 on Fitbit and 48 according to Cardiogram.

I've stopped taking multi-vitamins, now I take:
B12 (2000)
D (2000) (I am genetically predisposed to have somewhat lower absorption of both and my numbers show me at the lower end)

gGlucosamine (1000)
Q10 (200)
Citracal (half a dose (1 caplet), mostly because I found a large bottle :)
Alpha-GPC (300)
Curcumin (Natrol 2x250 CurcuWin)

I also take 2 caps of Olive Leaf extract, but when I run out, I am switching to bulk Olive Leaf Powder from Frontier, maybe 3-4 grams a day.

I am a vegetarian, mostly vegan, except that I eat cheese maybe three times a month and eggs maybe once a month.

Since I started being more religious about tracking my food intake and nutrients with Cronometer, as well as going for a three mile hilly hike/run 5-6 days a week, my BMI has dropped to the high 18 and my body fat, according to my scale hovers about 10%. I now eat within a 9-12 hour window. I am almost struggling to eat enough to keep up to 80%-85% of my caloric requirement, based on Fitbit and Cronometer -- I have to often eat over 2000 calories to do it. Don't need to get skinnier :) I am 6'1", 141 lbs today, 13.8 lbs fat, 120.6 lbs muscle mass, 6.5 lbs bone mass and 85.7 lbs body water.

I'll post what happens based on the Omega-3 to Omega-6 ratio change in about six months, when I'll have another blood panel. I like data and this is kind of fun for me.

I am curious if someone else has already done it?

My experiments run more in the line of nutrients versus bodyweight/bodymass. Buy the way, the new feature in the gold cronometer version allows direct correlation between variables, for example you can choose plots to superimpose your bodyweight to omega 3/6 ratio and see the joint behaviour of them.

It is more usually used to monitor Calories vs bodyweight but ha sno limitations I reckon. Only drawback you must subscribe to the gold edition.

in addition to legumes (Black Gram, since it has a great Omega-3 to Omega-6 ratio

I wouldn't be too concerned about the ratio for Black Gram since it's almost fat free.

Here is the nutritional data I have found for Black Gram (also known as mungo beans or Urad Dal):

"Mungo beans — aka Urad Dal — are by far the best choice with 603mg Omega 3 and just 43mg Omega 6 in one cup cooked (not to be confused with mung beans)."

So, after running close to 1:1 ration of Omega-3 to Omega-6, I noticed some significant changes:

Cholesterol: 153
LDL: 72
HDL: 71
Triglycerides: 51

My testosterone has gone up a bit, to just over 900 ng/dL

Interestingly, my IGF-1 has also gone up to over 180 ng/mL, although my insulin is pretty low at 2.5 uIU/mL, with glucose at 83. My protein intake (all plant) is 1.39g per kg, which is kind of high, I guess, but I don't know if I can drop it significantly and still stay all green for all the nutrients in Cronometer.

Today Withings has me at 64.2kg, 18.7 BMI,  9.6% body fat and 85.8% muscle mass.


I am a vegetarian, almost vegan, so my Omega 3 comes from stuff like flax, chia, legumes, walnuts and greens. Almost no olive oil (maybe 3-4 times a month, about 2 tbsp at a time or so). I do take olive leaf powder almost every day.

So, the big change is the drop in total cholesterol. I wonder what's with the IGF-1, but I am happy with my numbers overall and will likely keep the the 1:1 Omega 3 to Omega 6 ratio going forward.

I just completed a four-month experiment where I took 900mg of EPA+DHA each day. In the six months period prior, I was taking half of that amount, or 450 mg. Prior to that I was not taking any.

The results confirmed my suspicions that supplementation with Omega-3s is detrimental to my blood markers.

Back when I cut out olive oil and was not supplementing other than eating flax seed every day and based on Chronometer, my Omega-3 to Omega-6 consumption was roughly 1:1, my total cholesterol had dropped to the mid-140s.

After listening to a bunch of lectures and reading studies, I took an Omega test and my score was sort of low, so I tried supplementing, but my cholesterol went up. I stopped Omega-3 supplementation for a while because of it, and it leveled off.

So, I kept hearing about the great benefits of Omega-3 supplementation on shows like Atta's and Rhonda Patrick's, and decided to try again, And like clockwork, my total cholesterol goes up as does my LDL-C, and they are dose dependent, apparently.

Supplementing with 900mg of Omega-3s:

C-Total: 185 mg/dl
HDL-C: 66 mg/dl
LDL-C: 109 mg/dl
VLD-C: 10 mg/dl
Apo B: 82 mg/dl

Lipoprotein(a): 75 nmol/L

450mg of Omega-3s:
C-Total: 164 mg/dl
HDL-C: 65 mg/dl
LDL-C: 90 mg/dl
VLD-C: 9 mg/dl
Apo B: 76 mg/dl

Lipoprotein(a): 39 nmol/L

No supplementation with Omega-3s:
C-Total: 138 mg/dl
HDL-C: 63 mg/dl
LDL-C: 69 mg/dl
VLD-C: 6 mg/dl
Apo B: 64 mg/dl

Lipoprotein(a): 21.8 nmol/L

The Lipoprotein(a) is the weirdest, as everything I read is that it is relatively stable through one's lifetime and needs to be tested only once. Apparently not, in this case. For what it's worth, my doctor claims that he sees variations, so maybe I am misreading something.

I have started questioning the methodology of the studies, as I have noticed that those interviewed are generally connected with the industry, either involved in selling supplements, or promoting tests by entities they have interest in. Then there is the Levels type company consultant or employee, who pushes the high fat diet because that's what keeps the CGMs at a flatline and the subscriptions going.

It's an experiment involving a single subject, of course, and I may just be weird. Or wrong. But in any case, I am done with Omega-3 supplements.

A possible explanation here is a methodology of the testing. AFAIR there is an old way to do the things where no real "fractions" testing is done, there are calculations. In this case Lp(a) which is a part of LDL fraction could perhaps suffer if LDL is not directly measured but calculated with formulas. This is just a guess how it could be wrong, no idea if actually it is done that way. But this raised my curiosity and I will give this test another shot when will do my next tests.

Regarding other lipidogram-related stuff and omega-3 supps, from my experience the things looks a bit different.

My TC/HDL/LDL values are oscilating constantly in +-5-7% range, so I can't derive the conclusion if omega supplements are causing any difference and so far I am not ready to cancel it out due to (probably useless) race to get the recommended o3/o6 ratio in the test.

I am supplementing 2 huge Now ultra caps, thus 2x 500/250 daily for a year or so, last time my apolipoB was the same as before I switched to supplementation instead of small amounts of fish and I thought it is pretty stable thing as well. Maybe this one also should be re-tested, then o3/o6 ratio assesment and maybe I will drop the supps because the longer I think about them the less I am sure that this is not a pure marketing, despite people saying these things are the best studied molecules and they are needed "for sure".

thanks for the suggestion, Igor. I considered the possibility of a lab problem, but when I went back and checked and all three apo(a) tests were done by Labcrorp. While this doesn't eliminate the possibility, it reduces the likelihood.

Other lipid markers are off too, like my Free Fatty Acids, which have literally doubled at 0.7 mEq/L from before supplementation.

Also, my Insulin has doubled at 7.2 ulU/mL, which supports my theory (high free fatty acids prime one for insulin resistance).

I've eliminated Omega-3 supplementation and will retest in about three months to see if it has had an effect. I plan to keep most other things the same.

Indeed, such a radical change from a such relatively minor dietary adjustment is extraordinary.

(And I can assure you I  have researched the hell out of that subject.)

I am open to any other suggestions for the cause 🙂

I don't have any other issues that pop up on the tests, with thyroid, kidney and liver values all good, low inflammation markers, low PWV, no tissue injuries and no other drugs/supplements.

But even if the lipo(a) value is off because of a lab error or methodology, my lipids are definitely significantly worse than when I was not supplementing with Omega-3, and they get worse with increasing the dose.

I am wondering if the results showing supplementation benefits are because study subjects already have metabolic and lipid issues, while in my case I started Omega-3 supplementation while at what I consider to be optimum numbers for someone my age.

To boot, my Lp-PLA2 activity has also increased with supplementation 😞

Of course, it may be simply correlation, but this is my second try with Omega-3 supplements, and both had negative effects on my lipid markers. And this time it got worse as I doubled the dose.

I guess I'll know if elimination of Omega-3 supplementation improves my results in about three months.

Hi, Saul!

Just curious, what is "excellent" and are you on any medication that affects cholesterol?

So, it seems that Omega-3 supplementation, does increase cholesterol:

Despite their excellent ability to reduce triglycerides naturally, EPA and DHA actually increase LDL cholesterol, concerning some doctors and medical researchers.[4] All types of EPA/DHA seem to have this LDL-increasing effect, including prescription-based fish oil (Lovaza), over-the-counter fish oil supplements, and EPA/DHA supplements made from algae instead of fish.

The purported benefits of such increase being of the "large and fluffy" variety are at least debatable. And at this point I am also dubious about the patented Omega-3 Index test I have paid for a couple of times, as the more I look into it, the less it makes sense except as a supplement-pushing scheme.

It's quite quite telling that it's not easy to find such info about Omega-3s, as virtually all headlines fail to mention this, even when referring to studies that find such an LDL-C increase, despite the "fluffy" qualifications.

@Saul, I am still curious if you are on statins and what is "excellent" as it seems it may be pertinent to one's decision to supplement with Omega-3s.

I'll reserve final judgment for myself until I test again in three months or so, but I have become far more leery of medical headlines, and even many studies lately.

Well, Dr. Klaper changed his Omega-3 supplementation practice.

I am still not convinced of the benefits of supplementation, partially because high Omega-3 is not necessarily prevalent among studied populations with unusually high longevity, and partially because I am inclined to think that supplementation may dial down natural conversion. Plus, I am not convinced that the Omega Test is relevant to cognition.

But here it is:
