An Ingredient Geek's Guide to Buying Fish Oil

4 Steps to Getting the Good Stuff

Smart people take fish oil. Really smart people know the exact kind to buy and how much to take. Here's your guide.

I bought my first supplements at age 16: some chalky protein powder and a "kit" of assorted mystery tablets. I'm not sure what that kit contained, but the guy on the package had big muscles. Research complete!

Thankfully, I later educated myself about supplements. I became a total ingredient geek. I've been a supplement consumer ever since and an employee of a supplement company for over 25 years.

I used to assume that everyone took a similar path: they hear about a supplement's benefits, they do some research to know exactly what ingredients to look for and how much to use, and then they carefully read labels and compare products.

Well, most people don't do that. Take fish oil for example. Millions of people hear about the health benefits (which are indeed awesome), and then they either grab a bottle of the cheapest stuff at the grocery store or order whatever is 20 bucks or less on Amazon. Predictably, many don't get any of the benefits.

Let's fix that. Here's how an ingredient geek buys fish oil (Buy at Amazon).

The Geek's Guide

Step 1: Purity

First, I want a clean fish oil supplement. This was a problem in the past. When fish oil first hit the market, many were rancid and all stank to high heaven. The refining process sucked. Some cheapo products still have these issues.

High-quality fish oil supps use molecular distillation. They're rigorously tested for PCBs, dioxins, mercury, and other heavy metal contaminants. They're also self-emulsifying. This removes all or most of the aftertaste and "fish burps."

Step 2: DHA Content

I want a fish oil with a lot more DHA than EPA. The latter is good stuff, no doubt, but the more we learn about fish oil, the more we realize that DHA is the powerhouse omega-3 fatty acid.

For example, DHA plays the biggest role in preventing or slowing Alzheimer's, boosting sexual health, preventing heart arrhythmias, lowering diastolic blood pressure, and increasing lifespan in general. DHA is the more powerful inflammation smasher.

Men especially need more DHA in their fish oil. Men have lower amounts of DHA despite eating the same amount of fatty acids as women. The natural biosynthesis of DHA is much higher in women than it is in men. (Woman privilege!)

DHA also has the biggest impact on glucose utilization and neurotransmission, meaning that if you take fish oil for its anxiety-squashing benefits, you want it to contain mostly DHA.

So, why do most fish oils contain more EPA than DHA? Because that's what fish naturally contain. A supplement company has to do some manufacturing ninjutsu to make their product higher in DHA, which takes more effort and makes the product cost more. But most supplement makers don't care. They know their average customer doesn't know a thing about DHA and just wants to feel good about taking fish oil.

Here's another dirty trick the cheap fish oil makers use: They don't tell you the ratio of EPA and DHA. Instead, they lump those numbers together on the label: it's often 500 mg or less. Since whole fish usually has about a 2:1 ratio, that means the actual EPA/DHA ratio is more like this:

  • 333.33 mg of EPA
  • 166.67 mg of DHA

That's a puny amount of DHA and part of the reason why those supplements are under $20.

Step 3: The Amount Needed for Benefits

Almost every good study on fish oil shows its numerous health benefits, but not all of them. If you dig deep into these studies, what you often find is that the researchers simply didn't use enough.

For example, in the studies looking into fish oil's effects on anxiety and depression, the effective doses are typically 2000 mg or more. Lower doses didn't do the trick. Another example: One study looked at fish oil's ability to combat heart attacks and strokes but only used 840 mg. a day of EPA/DHA. The scientists concluded that fish didn't help much with the stroke part. However, other studies show it does if you use 2,200 to 3,000 mg.

Knowing this, the supplement connoisseur (geek) looks for highly concentrated fish oil.

I looked up some of the best-selling brands on Amazon, products that sell up to 20,000 units per month. One such product only contained 1000 mg. If you follow the directions on the label, you won't be getting enough fish oil to reap any benefits.

Sure, you could take more, but now that bargain price isn't such a bargain, is it?

Step 4: The Bioavailability

Pharmaceutical companies don't just think about the drug itself. They think about how to get that drug in you to do its job: its bioavailability and absorption efficiency. That's the best way to ensure consistent results.

Cheap fish oil makers gather up a bunch of fish, squeeze them dry, and encapsulate the oily fat. Okay, they probably do more than that, but they don't consider bioavailability.

High-absorption fish oil is made using self-emulsification, a process where the fish oil is formulated to naturally form a stable emulsion when it comes into contact with an aqueous phase, like the digestive fluids in the gastrointestinal tract. This process enhances the bioavailability and absorption.

If a fish oil product doesn't say it uses self-emulsification, then you're probably just getting juiced fish.

This Fish Oil Checks All the Boxes

As an ingredient geek who got to be an "insider" in a supplement company, I see how our fish oil is made: it checks all the boxes above. Every step is accounted for.

Flameout DHA-Rich Fish Oil (Buy at Amazon) is clean and highly concentrated. It contains more DHA than EPA and it's self-emulsified.

Buy Flameout at Amazon

Flameout contains five times more DHA than EPA:

  • DHA 2000 mg
  • EPA 400 mg

The total amount of this triglyceride form of fish oil is 4200 mg and you get it all in just a three-softgel serving. There's no need to double or triple the dosage to get the benefits.

The price? Well, it's not under $20, but it also doesn't suck.

Hey, buy whatever fish oil you want. But do your body a solid and follow all the steps above to ensure you're getting the good stuff.

Your article today: “DHA prevents heart arrhythmias”

NY Times article today:
“In a 2021 study, Dr. Albert and her colleagues combined the results from seven trials and concluded that taking omega-3s was associated with a 25 percent greater risk of A-fib on average. The risk was even higher when people took larger doses, they found.”

:face_with_raised_eyebrow::man_shrugging:

Hmm, researchers funded by multiple pharmaceutical companies find that elderly people who already have heart problems tend to have more heart problems as they get even older, even though they self-reported taking fish oil. Seems legit. :wink:

This article reminded me - I recently opened a bottle of Flameout from my previous shipment and it abso-fucking-lutely reeked like rotten fish washed up on the beach. What’s more, the capsules were stuck together like a 13 year-old’s dirty socks.

Being the forty-something old bodybuilder that I am, I’ve lived through the explosive shits of Phosphagain loading phases and drank American Bodybuilding’s Critical Mass in the 90’s, whose protein would form an appetizing snot-like consistency as in went down your throat (insert pun here), and then give you the explosive shits.

So figuring I’ve lived through worse, and with another Flameout shipment a week or two away, I pried the capsules apart and took them anyway. Man, was that rough, lol.

Even though I refrigerate my Flameout after opening, the smell and taste initiated the gag reflex each time I took it. I made it through a week or so until my new shipment arrived, which had none of the aforementioned issues, of course.

Naturally, I coulda/shoulda reached out to support (the wife told me to, but I wanted to show her how tough I was), as the only thing I can think of is there’s a ruptured capsule somewhere in there. It did, however, make me curious - is there any deleterious effect to taking these if one busted in the bottle, or does it simply just become a very unpleasant experience?

Sounds like something happened in shipping. Contact customer service and I’m sure they’ll send you a replacement.

Thanks, Chris, I’ll do that.

Another more ponderous question - given all the mixed messaging from the scientific community regarding high-dose fish oils (over 1g) and heart arrhythmias, specifically a-fib, are you aware of any evidence that Flameout’s much higher DHA/EPA ratio might offset or reduce such risk (if it even truly exists)?

I’m always skeptical of metadata studies such as these, as they do not control for a number of variables, and the media is always quick to imply causation.

  1. Should we refrigerate after opening the bottle?

  2. Just started my third bottle. I have to say, I think it has definitely helped with mild depression and anxiety that I would frequently get. Also, even though my cholesterol is always low (170-180), the ratio of bad to good cholesterol has always been not good. With my most recent labs, mint total was 160 and my ratio was improved as well. I’ve also been eating very healthy lately, but I do think the fish oil also helped.

You don’t have to, unless maybe you’re not going to finish a bottle in months. I do keep my Flameout in the fridge, but that’s just an old habit really. (In the “old days” with super stinky fish oil, people would even keep it in the freezer.)

I’m not, but we have to assume that most studies use standard fish oil, which is much higher in EPA than DHA (same as the fish it’s made from). I’d be curious about this too because every study I’ve seen recently is focusing on DHA as the real powerhouse of the duo. And in these self-reported, free-living studies, we also have to assume that most people are grabbing whatever fish oil is sold on the cheap at their grocery store pharmacy section.

does Fish Oil impact your energy levels?

Yes, but not in a traditional stimulant kinda way.

For example, improved blood flow and oxygen delivery to tissues might indirectly boost energy levels, along with reduced inflammation in turn reducing the fatigue that can come along with it. Same with the perceived-energy side of things: fish oil can stave off depression which will likely present as improved “energy.”

So, yes, but not in a “keep you awake at night” kinda of way.

That fits

I got cute recently. Decided that since I’m eating two to three helpings of fish a week that I don’t need fish oil. Because I read that somewhere. So I quit taking my DPA… Don’t do that. I noticed energy levels impacted. I would get tired. In the middle of the day. And maybe it’s depression because those two things can be tied together… But I’m pretty confident it is from me stopping my fish oil intake. Because it’s the only thing that’s changed.

Thanks for the feedback

@Chris_Shugart The first thing that struck me was that an obese/lazy/genetically unfortunate person (currently healthy) may not be willing to diet/and or exercise. Instead they take a fish oil supplement. And probably others. Then they get heart disease - but thats more likely because of their lifestyle decision not the presence of the supplement.
By the way this is not a homage to fish oil supplements, its an observation on the way so many studies do not observe the old adage of the way you do something is the way you do everything. Good habits = multiple good habits and vice versa.
Studies need a way to filter out other variables. This is even more difficult in meta studies which are unlikely to set the same parameters to each other. And in MHO a major flaw in meta studies generally.
