Before you buy
Both of these are Amazon bestsellers people cross-shop for the same reason: they want a clean fish oil that actually has omega-3 in it, not a cheap 1,000 mg "fish oil" softgel that hides 300 mg of EPA+DHA in fine print.
The real decision here is not "which brand is better." It is how much EPA+DHA you actually want per day, in how many pills, for how little money. Get clear on that and the winner picks itself.
One thing to settle up front: there is no official RDA for EPA or DHA. The NIH Office of Dietary Supplements notes that intake guidelines exist only for ALA, the plant omega-3. Most general-wellness users land somewhere around 250-1,000 mg of combined EPA+DHA per day, which both products cover easily.
If a doctor has flagged your triglycerides and floated a gram-level dose, that is a different conversation, and a different product. We will get to that.
What you actually get per serving
This is where the two diverge, and where most "they're basically the same" reviews go wrong.
Viva Naturals Triple Strength packs a lot into a serving. Two softgels give you 1,500 mg EPA, 570 mg DHA, and 50 mg DPA – about 2,070 mg of EPA+DHA plus a little bonus DPA, per the brand's Amazon product listing. That is a genuinely high-potency serving.
Sports Research keeps it simpler. One softgel of its AlaskOmega 1250 mg fish oil delivers 690 mg EPA and 260 mg DHA, or roughly 950 mg EPA+DHA per pill. Take two and you are at about 1,900 mg, close to Viva's single serving.
So the headline gap is real but smaller than it looks:
- Viva Naturals: ~2,070 mg EPA+DHA in 2 softgels, plus 50 mg DPA.
- Sports Research: ~950 mg EPA+DHA in 1 softgel, or ~1,900 mg in two.
If swallowing fewer, bigger pills matters to you, Viva gets you to a high dose faster. If you would rather titrate your dose pill by pill, Sports Research is more flexible.
Triglyceride vs ethyl ester, and why it barely matters here
You will see a lot of marketing noise about fish oil "form." Here is the short version that actually applies to this matchup.
Fish oil comes mainly as natural triglyceride (TG), re-esterified triglyceride (rTG), or ethyl ester (EE). The cheapest concentrated oils are usually EE. The body absorbs TG and rTG forms more readily than EE.
The most-cited data is Dyerberg and colleagues, 2010, which reported EPA+DHA bioavailability of 124% for re-esterified triglycerides and just 73% for ethyl esters relative to natural fish oil. That is a meaningful gap if you are comparing a TG oil against an EE oil.
But here is the catch: both products in this comparison are triglyceride-form oils. Viva Naturals uses rTG; Sports Research uses a TG concentrate. So the absorption argument that sells premium fish oil does not separate these two. Neither is the cheap EE form you should worry about.
The practical takeaway: take either one with a meal that has some fat, and your body will use the omega-3 well. The form difference here is a wash. If you want the deeper science, our breakdown of omega-3 TG vs EE vs krill bioavailability covers where form actually moves the needle.
Third-party testing and freshness
This is the part that should actually move your decision, and it is good news for both.
Both products carry IFOS certification. The independent International Fish Oil Standards record for Sports Research confirms its AlaskOmega oil is tested for purity, potency, and oxidation, and it also lists IGEN non-GMO testing. Sports Research markets this as a 5-star IFOS rating, and the oil is single-source wild Alaska Pollock with MSC sustainability certification.
Viva Naturals is covered too. The IFOS certification record for Viva Naturals Triple Strength shows multiple tested lots on file.
Freshness is the quiet differentiator with fish oil, since rancid oil is the main reason supplements taste fishy and "repeat" on you. Independent lot testing is the strongest signal you can get that an oil is not oxidized, and both brands clear that bar. If you have ever burped your way through a no-name fish oil, this is why the certified options are worth the small premium.
Cost per gram of EPA+DHA
Price per bottle is a trap. The honest metric is cost per gram of EPA+DHA, because that is the active part you are paying for.
| Product | EPA+DHA per serving | Form | 3rd-party testing | Approx. cost per gram EPA+DHA |
|---|---|---|---|---|
| Viva Naturals Triple Strength | ~2,070 mg (2 softgels) + 50 mg DPA | rTG (re-esterified triglyceride) | IFOS certified | ~$0.36-0.37 |
| Sports Research AlaskOmega 1250 | ~950 mg (1 softgel) | TG concentrate | IFOS 5-star + MSC + IGEN | ~$0.23-0.26 |
The math leans one way. Sports Research's 90-count runs roughly $17-22, and the Costco 150-count drops it further, landing the oil near $0.23-0.26 per gram of EPA+DHA. Viva's 90-count sits around $34 for fewer servings, which works out to roughly $0.36-0.37 per gram (all as of writing – check current price, because both swing on coupons and stock).
On pure value, Sports Research is the clear winner. Viva is not overpriced for what it is; you are simply paying a bit more for the convenience of a high-dose, two-pill serving with DPA included.
The burpless angle, and who each one is for
"Burpless" is Sports Research's main pitch, and there is something behind it. A fresh, well-distilled TG oil is far less likely to cause fishy reflux than an oxidized one. Sports Research leans into this with its single-source Pollock oil, and reflux complaints in reviews are genuinely low.
Viva does not market a burpless coating, but because it is an IFOS-tested rTG oil, fishy repeat is uncommon there too. If you have a sensitive stomach, taking either with food handles most of it.
Here is the clean read on fit:
- Choose Sports Research if you want the best price per gram, a flexible one-softgel dose, sustainability certification, and the gentlest feel.
- Choose Viva Naturals if you want the highest dose in the fewest pills and value the bonus DPA, and you do not mind paying a little more.
For most people doing daily general support, the value pick is the easy call.
The value pick and a smarter alternative

For everyday omega-3 support, Sports Research is the better-value buy of these two, and the burpless feel makes it the easier one to stick with. If you want a bigger dose without juggling pills, Viva Naturals earns its small premium.
But be honest about your goal. If you are chasing a clinical dose for high triglycerides, you would need to swallow a small handful of either product daily, and at that point a prescription omega-3 is more appropriate. That is a doctor conversation, not an Amazon one.
It is also worth seeing how these stack against the premium tier. Our look at whether Sports Research omega-3 is worth it digs into that, and the Nordic Naturals vs Sports Research omega-3 breakdown shows what an extra few dollars per gram does and does not buy you. If Nordic's price stings, the Nordic Naturals alternatives on Amazon roundup lines up cheaper options.
FAQ
Which has more EPA and DHA per serving, Viva Naturals or Sports Research? Viva Naturals, on a serving basis. Its 2-softgel serving gives about 2,070 mg of EPA+DHA plus 50 mg DPA, while one Sports Research softgel gives about 950 mg. Two Sports Research softgels close most of the gap.
Are both fish oils in the triglyceride form? Yes. Viva Naturals uses re-esterified triglyceride (rTG) and Sports Research uses a triglyceride concentrate. Because both are TG-type oils, the absorption advantage that TG has over cheaper ethyl ester oils does not separate these two.
Which is cheaper per gram of omega-3? Sports Research, by a clear margin. It works out to roughly $0.23-0.26 per gram of EPA+DHA versus about $0.36-0.37 for Viva Naturals, as of writing. Confirm current pricing before you buy.
Are these fish oils third-party tested? Both carry IFOS certification through Nutrasource, which tests for purity, potency, and oxidation. Sports Research adds MSC sustainability and IGEN non-GMO testing on its wild Alaska Pollock oil.
Will either one make me burp fish? Less than a cheap, oxidized oil would. Sports Research markets a burpless feel and reflux complaints are low; Viva’s IFOS-tested rTG oil is also unlikely to repeat. Taking either with a meal helps most.
Can I use these for a doctor-recommended high triglyceride dose? You could, but you would need several softgels daily to hit 2-4 grams of EPA+DHA. For a true clinical dose, talk to your doctor about a prescription omega-3 rather than scaling up a retail tub.
The verdict
These two are closer than their marketing suggests. Both are clean, IFOS-certified triglyceride oils, so you are not choosing between good and bad – you are choosing between value and convenience.
Sports Research is the better everyday buy. It costs less per gram of omega-3, the single-softgel format lets you dial your dose, and the burpless feel makes it easy to keep taking. Viva Naturals is the pick when you want a high dose in two pills, with a bit of DPA along for the ride, and you accept the slightly higher price.
Your next step: decide your daily target first, then buy on cost per gram, not cost per bottle. If your goal is a clinical triglyceride dose, route that decision to your doctor instead.
