    Arachidonic Acid: X-Factor vs Egg Yolks?


    For myself and those of you who might be interested i've done a bit of a comparaison between Arachidonic Acid content in eggs and X-factor by muscular nutrition. I'm not a nutritionist or qualified to make and recommendations, so take what i say at face value.

    So I'm assuming the content of Arachidonic Acid of eggs: (sources below)
    at the high estimate:
    195mg per yolk

    low estimate:
    65mg per yolk

    duck eggs:
    445mg per yolk


    Quantity of Arachidonic Acid 4 pills daily X-factor:
    250mg x 4 = 1000mg Total
    How many Chicken Egg yolks needed to match this?

    High Estimate:
    1000 / 195* 2 = 5.12 yolks

    Low Estmate:
    1000 / 65 * 2 = 15.38 yolks

    How Many Duck Egg yolks? (Sourced from one of the links above)
    1000 / 445mg = 2.24 yolks

    Cost wise:

    X-Factor:
    100 Softgels for $45 (nutraplanet.com)
    100 * 250mg = 25g total per bottle
    25g / $45 = 0.55g/$

    Chicken Egg Yolk:
    High Estimate:
    Tesco.co.uk Big and Fresh box of 10 eggs = 1.98 = $4.12
    195mg per yolk * 10 = 1950mg per box
    1.95g / $4.12 = 0.47g/$

    Low Estimate:
    Tesco.co.uk Big and Fresh box of 10 eggs = 1.98 = $4.12
    65mg per yolk * 10 = 650mg per box
    0.65g / $4.12 = 0.16g/$

    Cheap Eggs: (High est)
    Tesco Value Eggs Minimum Weight Box Of 15 = 1.28 = $2.66
    195mg per yolk * 15 = 2925mg per box
    2.92g / $2.66 = 1.09g/$

    Duck Egg Yolk:
    891 mg per yolk
    Tesco Finest duck Eggs = 2.28 for 6 = $4.75
    445mg * 6 = 2670mg per box
    2.67g / $4.75 = 0.56g/$

    From this (assuming my calculations are right) both Duck eggs and chicken eggs can be comparable in cost to x-factor as a source of AA. Of course there is a downside to eggs, you get more fat/cholesterol, but then also you get more protein.

    So I regularily consume 5-6 eggs per day just for natural bulk, does that mean i'm on an equivalent X-factor cycle? Or is there another ingredient in X-factor which makes it more potent? Maybe i might even switch to duck eggs and see if there is any difference.

    Regardless i'll still be trying an x-factor cycle soon. Feel free to comment/flame etc..


    These estimates are per 100g (Including egg white, although AA is only found in the yolk). I'm estimating 100g is about 2 eggs.
    Sources Arachidonic Acid per 100g/egg.

    390mg - jn.nutrition.org/cgi/content/abstract/125/10/2528
    375 mg - food-allergens.de/symposium-vol1(2)/data/birds/birds-composition.htm
    163.1 mg - ps.fass.org/cgi/reprint/84/1/167.pdf

    interesting writeup, there are a few of us here currently on Xfactor and also bumped our egg consumption up...

    would love to see some replies

    I just started my first xfactor cycle on monday using bulk powder, I am eating at least 1 dozen whole eggs a day and steak just as recommended. I already feel it working, I'm much more sore then I usually am and I got a pump all day long, tmrw is my first off day since I started, I thinkthe pump will stay through then. I weigh the most I have in probably 4 months, 188. I can start seeing abs showing, which hasn't happened in a long time and veins in my arms popping out that have never popped out before, long after my workouts are done... today was arm day and the pump was so big that it hurt my forearms really bad where I could barely complete my preachers.... I love this stuff, looking forward to seeing big gains!

    Looks like you did your math consistently, not sure if there were any assumptions made that are false. I haven't looked into XFactor/AA products too seriously. Looks like some good math though, and could prove interesting.
    I wonder what the bioavailability is in eggs vs. the caps. Eggs are pretty natural, and if it's like egg protein it should have an almost perfect score.

    Nice write up. Props!

    do you AA consumers only take AA PWO. I was thinkingabout running it this way as to avoid any lipid profile or cardiovascular risk.

    Also with the eggs, part of the question is if cooking damages AA. from what I read, hard boiled does very little damage, breaking open the yolk while cooking (scrambled) does the most damage, over medium or easy is close to boiled.

    I've been using the 65mg number, and eating 16 eggs a day, generally 4 over easy and 12 hard boiled. breakfast today was eggs over easy on top of a tilapia fillet with some seasoned salt. yum!

    I got my 65mg from Egglands Best nutritional department.

    http://www.egglandsbest.com/

    i've stopped using their eggs actually so as to avoid the omega 3 content, but I believe that its accurate.

    Values for Steak and liver from jn.nutrition.org/cgi/content/abstract/125/10/2528

    Beaf steak (Minced Steak is cheaper)
    9 = $18.7353 per 1kg
    So 200g steak is equal to about 1/4 of an X-factor pill
    350mg of AA per 1kg
    0.35 / 18 = 0.019g/$

    Pig Liver
    1.88 = $3.91 per 1kg
    200g Liver = 2.35 X-factor pills
    2940mg per 1kg
    2.940 / 1.88 = 1.56g/$

    Liver appears to be a very cheap source, but personally i can't stand it.

    I wonder if the AA content of liver tabs is very high? I wonder if someone might release some liver tabs standardized for AA?

    So far my diet looks to contain about 2 or 3 grams... And I figured I just had doms cause I have been training hard, but come to think of it, I am sore as hell.

    AA is a patented omega 6 fatty acid. gaspari paid to have the right to use AA. I think paying to get AA standardized for liber tabs or what not would make it super expensive considering that AA is basically owned by molecular nutrition.

    20:4 undifferentiated 720 mg 100g chicken heart raw
    20:4 undifferentiated 610 mg 100g chicken heart cooked,simmered

    Looks like the AA content does decrease with it being cooked. I could check eggs as well but im pretty sure it would apply.

    Easy 20:4 refers to AA or 20:4 n-6 does? On the web it just said 20:4 refers to AA.

    can of fish oil from sardines
    20:4 undifferentiated 3828 mg

    Downside is 2000 calories of fat for the 4mg of AA.

    V nice site, good find EasyEJL.

    Looks like Liver, Brain, Heart, pancreas (yum), egg yolk, fish oil and salmon seem to be the most abundant sources (Top 1000, 999 Foods Highest in 20:4 undifferentiated<br>(based on levels per 100 grams)). Assuming 20:4 undifferentiated is the same as 20:4 n-6

    Nutritiondata is an awesome site. The best part is if you're whipping up a recipe, you can add all the ingredients to the pantry, set it to the # of servings you made, and then you can print a label with the complete breakdown, right down to the minerals if you want. So massive chicken stew --> 6 Containers, Print labels and you've got some easy meals with all the numbers!

    wow. didn't know that! I was attracted the breakdown of nutritions in each foods. fullness vs nutrition. And a breakdown of fats carbs and protien. The detailed list of fatty acids and other details is very nice as well. better than any other calorie count website ive seen.

    Yum pancreas and oats for breakfast!

    20:4 n-6 is AA, but the undifferentiated includes 20:4 n-6 and20:4 n-3. So I dunno how much of any of these is 20:4 n-3. no way to tell from there.

    Eicosatetraenoic acid 20:4 (n-3) is an omega 3 acid, which your supposed to avoid while supplementing x-factor. I'm confused about the data on nutritiondata because it refers to 20:4 undifferentiated as eicosatetraenoic acid and it's common name as arachidonic acid. Any expert on here who can clarify?

    well look, about 4 others also fall in as eicosatrienoic acid. it does have that under systematic name, so perhaps AA falls into that "category" ? it does bind with same receptors...

    I'm not sure how you can patent a naturally occurring fatty acid. My bet is that the patent is really on the extraction method.

    The Patent is on selling/marketing it as a muscle buiding supplement (i think). You can still by it directly from manufacturers

    (Edit - Zootreeves beat me to it )

    I thought it was a patented by MN for a specific use of AA , namely to increase lean mass or something like that.

    Syntrax sells it as a test booster, but they are being sued my MN regardless.

    Im not sure why someone like NOW can't just sell AA with no claim other than its a dietary supplement, or a Omega 6 'blend' high in AA content. Probably because there is no real healthy lifestyle use of it, as most health professionals would not recommend mega dosing it.

    AA is added to baby formula, and Im sure MN is not getting a royalty on that, so there is likely an avenue that one could take, perhaps adding it to a protein mix? I dunno.

    what do you think of pig's liver as food rich in ArA? (870mg/100g) or lard (1700mg/100g)? Any health concerns?
