    Thank you, Doctor! I take fish oil because I don't eat fish often and I am a higher risk for heart disease. I was diagnosed with AFib with RVR last year and I guess I will chat with my PC and cardiologist if I should even be taking this supplement. You're the best.

    The actual incidence of Afib in the non-fish oil users was around 4.2%, while that in the fish oil users was 4.8% - this represents an absolute risk increase attributable to using fish oil of just 0.6%. Another study published in 2020 and included nearly the same group of participants as the current UK Biobank study found regular use of fish oil was associated with a 13% lower risk of all-cause mortality, a 16% lower risk of dying from cardiovascular disease, and a 7% lower risk of incident cardiovascular disease events (i.e., myocardial infarction or stroke).

    A cautionary note: The majority of "fatty fish" commonly available are Farm Raised and fed all kinds of cereal/antibiotics/growth hormones and other crap to increase production and profit. Buy wild caught fish but unfortunately these types of fish are hard to find in many areas and are way more expensive.. Do your research before just assuming the fish you buy at a grocery store is all that good for you because it's usually a mixed bag of good things for you wrapped in a "bad" package.

    Second comment: My anecdotal experience is: I used to have AF sometimes a decade ago and it went away for the most. A few months back I started taking 1h of Omega3 a day and after a few weeks I noticed palpitations and short bursts of what I felt when I was diagnosed with AF. I stopped the pills and the palpitations went away. I had no clue about this research then, on the contrary, my placebo mindset told me "this is good for your heart". Maybe a total coincidence, but funny that it fits.

    Omega-3 EPA and DHA does have some anti-inflammatory properties, which is helpful, but they are mostly beneficial for brain and skin health. It is Omega-3 ALA which is beneficial to heart health, and that is found in abundance in flax seed but is not present in fish oil. Fish get their omega-3s from algae, so it is reasonable to expect that omega-3 in algae oil would be the same. If purchasing fish oil, look for ones that are purified to remove mercury.

    I used to take 5 grams fishoil per day because several UA-cam/doctor influencers said optimal DHA/EPA were 1grams each, that required me to take 5 grams overall fishoil, and I started experiencing weird heart palpitations this year even tho I been doing this for several years.
    My hypothesis is that it was due to oil going oxidized because I opened the capsules and oil smelled really bad. I bought another brand, opened caps, oil smelled fresh and chest discomfort went away, but came back 3 weeks later so I opened the caps again and sure enough, the oil smelled fishy again, so it went in the garbage can.
    I don't want to waste more money on fish oil now, these caps go bad after few weeks even if they are in the refrigerator.

My continual shift in diet I feel was more the cure for the problem, but the only reaction I got from taking this, was if I bumped my arm on something I'd get broken capillaries. My triglycerides were down to 88 and I asked my doctor if I could stop taking the medicinal fish oil, my concern was I could get internal bleeding. I take a lower does of fish oil now instead of the prescription and no problems anymore.

    Comparison between
    the Sacha Inchi Oil and the Fish Oil
    I. The process of obtaining the supplies
    The Sacha Inchi (Plukenetia Volubilis Linneo ) is a seed obtained through the cultivation in organic earth located in the Central Forest of the Peru in medium altitudes and it implies all the corresponding agricultural works. The required extension area is related to the amount of production that is desired to obtain, 1 Ha of earth produces 1000 Kg of seed in the first year, then, the production increases gradually until the 3rd year, when it reaches its maximum productivity, the first harvest is achieved after 10 months; to obtain 1Kg of oil it is required an average of 6 Kg of seed. At the moment exists little seed offer in relation to the demand; The oil production does not yet reach important volumes due to the fact that it is a new product, and it will take its value in the market as the demand increases and the cultivation areas expand.
    The fish - usually fish of cold water - is the supply of the fishmeal and the remaining oil constitutes a sub-product which is directly encapsulated (softgels), or it is used as a base -deodorized - to elaborate other products, such as snacks, cookies, candies, tofees, etc”¦, which already have a wide established market since many years ago.
    II. Oil obtaining Process
    The Sacha Inchi is an organic vegetable product which content goes through an extraction process in cold, to be converted into an extravirgen oil, allowing the human being to count with a product which enables him to metabolize his own omegas (precursory acids O-6, O-3, and O-9), creating in consequence a natural order.
    The fish oil, having an animal origin offers the human being the O-3, metabolized by the said organism which was used as supplier source in the process of the oil production; the source precursor is the plankton.
    III.Comparison among their main components
    The Sacha Inchi has over 47% more content of linolenic acid, the O·3 precursor The fish oil has from 22% to 33% of O·3, being the anchovy the best fish for the O·3 Oil.
    Due to the fact, that the Sacha Inchi contains the precursor a-linolenic in superior quantity, it is able to produce more EPA and DHA (Omega 3), than any other fish and it offers an ideal combination of O·3 (in more content), besides the O.6 and O.9.
    The Sacha Inchi has 3.85% of Palmitic acid and 0.0% of Palmitic-oleic. & nbsp;
    The Anchovy has 19.9% of Palmitic acid and 10.5% of Palmitic-oleic.
    A less content of these components better for the human body.
    The Sacha Inchi has 93.69% of Unsaturated Fatty Acids.
    The fish oils can contain from 65% to 77% Unsaturated Fatty Acids.
    The higher percentage makes it more favourable to the health.
    The Sacha Inchi has 6.4% of Saturated Fatty Acids.
    The fish oils can contain from 22% to 35% of Saturated Fatty Acids.
    The lowest percentage of saturated fatty is the most healthy.
    The smell and the flavor of the Sacha Inchi is like the nature and similar to the beans.
    The smell and the flavor of the fish oil is well known. When a person takes softgels of fish oil may belchs the fish flavor.
    The complementary process to eliminate the characteristic smell and flavor of the Sacha Inchi Oil and the development of the sub-products with flavor discretion (final product), is already a reality and slowly, but in a progressive and sustained way they will occupy a higher level in the market to those products, which are elaborated on basis of fish oil, due to their superior characteristics.
    IV. Conclusion
    ALL THIS MEANS THAT SACHA INCHI OIL, IS THE PRECURSOR SOURCE OF O·3 (WITH AN IDEAL COMBINATION OF O·6 AND O·9) OF VEGETABLE AND ORGANIC ORIGIN ALLOWS THE HUMAN BEING TO METABOLIZE THEIR OWN O·3, BECOMING A VERY SUPERIOR HEALTH PRODUCT IN RELATION TO THE FISH OILS WHICH CONTAINS O·3.

      The body does convert the ALA in the sources you described to EPA/DHA , although in very small doses. There is also strong evidence that unsaturated fats have a separate absorption pathway from saturated fats. In other words, walnuts are very healthy, but fight fish oil for absorption, whilst providing way less of the EPA/DHA benefit. That steak on the other hand, may not be that healthy in comparison, but barely interferes with a EPA/DHA absorption from a supplement. Due to the low conversion rate of ALA to EPA/DHA, the amount of walnuts you'd need to generate a EPA/DHA load akin to a fish oil supplement is very high. It's probably not healthy to eat that many nuts for other reasons. The overall situation is nuanced.

    Yes, fish oil supplements did give me arrythmia, or atrial tachycardia. I was on statins, which eventually poisoned me, but because they gave me joint pain and swelling I was advised to take fish oil supplements. I did this for many years, but between the statins and the fish oil I became extremely ill. Now I have given both up and after 5 months I am finally feeling normal again, and managing my cholestrol with diet, which includes oily fish one to two times a week.

I also monitor my heart doing an ECG with my Apple Watch, regularly too. I have been taking 4,000mg of Fish Oil under advice of my doctor to counteract the problems I have with my bowels due to my Spinal Cord injury and I have had 0 issues with Atrial Fibrillation doing this for a number of years now.

    • @NoUseForMySoul
      @NoUseForMySoul 4 місяці тому

      ALA gets converted to EPA/DHA at very low ratios. As far as I'm aware, positive health effects boil down to the EPA/DHA. That does not make ALA bad, it's just way harder to get a significant effect in a study without feeding a person absurd amounts of ALA.

    • @Reversed82
      @Reversed82 4 місяці тому

      AFAIK (might be inaccurate) DHA/EPA in fish bioaccumulates from some species of algae, so effectively algae oil is kind of just skipping elements in the food chain. also "algae oil" sounds generic but commercially, as i understand it, it's apparently only viable to produce it via some specific types of micro-algae.
      i'm _guessing_ it wouldn't matter in the trials whether fish oil or algae oil would be used since it's the same molecule 🤷‍♂

    Many people get confused by the numbers. We should not conflate the FISH OIL number on the front of the bottle, say 1000 mg and the OMEGA -3 number (on the front or back of the bottle) say 300 mg omega-3. Only part of that number is what we're after.
    Only part of that Omega-3 is the vital elements called EPA and DHA which could add up to only 250 mg. So when it is suggested you take 1000 mg it is referring to that last group, EPA and DHA. So I take 4 Softgels, 250 x4 = 1000 mg EPA and DHA,. Thats 4, 1000mg of FISH oil totaling 4,000 mg FISH OIL but only 1,000 mg EPA/DHA.... Am I correct???

    Complicated subject! I had been taking the Costco TruNature EPA/DHEA product (600 EPA/300 DHEA) for a while but have temporarily discontinued largely due to this study. Of course, I have preexisting cardiovascular issues. I have replaced it at least temporarily with very high doses (3,750 mg) of aged garlic. My worry in using both would be blood-bleeds in the brain - which is one of the dangers of going too far to thin the blood. I've also taken a low dose of Nattokinese for years. Recent research that I've come across on UA-cam seems to be suggesting that large doses (either 11,000 or 22,000 - not fully clear on this) of Nattokinese taken twice daily (due to the supplement's half-life...) is capable of removing plaque from arteries. That Vascepa study conducted by company a few years back, combining large dosages of EPA-only with a statin drug also claimed to be capable of removing preexisting plaque from arteries. What to believe? I don't know. It would seem to me that for patients with significant coronary artery buildup, removing preexisting plaque would be the ideal.

    Thanks for the update. I'm wondering if there have been any studies comparing Omega-3 precursors to DHA/EPA supplementation, or even just looking at these precursors without comparing them to another intervention, in terms of cardiovascular outcomes. Speaking of course about ALA (either in supplement form, or in foods like flax meal, hemp seed meal, or chia seeds). I was diagnosed with heart disease over 10 years ago and went plant-based about 7 years ago, and at that time I went on the strict Esselstyn diet, which I later moderated off of, but still continue to eat plant-based, and take in about 2 tbsp of flaxmeal per day. I've tried algae oil on occasion but never sustained it possibly because I detected feeling a bit "off" when taking it, although it could have been psychological, or unrelated, who knows. I take a statin and am in generally good health with no known cardiovascular events for over 5 years now, low LDL for that time period as well. I haven't heard of such studies with ALA supplements or foods and I really wish there was something that might definitely say whether this was of a benefit at all or completely useless (at least in terms of prevention of secondary events).
