Price: Viva costs about 45% less per gram of omega-3

On Viva’s own store, 180 softgels cost $55.99 (90 servings). On Carlson’s, 130 softgels cost $49.90 (65 servings). Viva gives more omega-3 in each serving and still costs less for it: $0.62 a serving against $0.77. On Amazon the order is the same.

Cost per 1,000 mg of EPA+DHA = price ÷ servings ÷ (mg of EPA+DHA per serving ÷ 1,000). List prices from each brand’s store, September 29, 2026; Amazon prices for the bottles our buttons open (Viva 180 softgels, Carlson 130 softgels), checked November 6, 2026.

Testing: both are on IFOS; Viva has far more lot reports

Both lots we read passed every test and held more EPA and DHA than the label says. IFOS also checks freshness, meaning how far the oil has started to spoil. Lower numbers are fresher. Peroxide measures early spoiling: 3.87 in Carlson’s lot and 0.55 in the Viva lot we read (lot SG26050712), against a limit of 5. IFOS’s overall score, TOTOX, adds a second test: 17.74 for Carlson and 4.73 for Viva (limit 19.5). The fish oil trade group GOED says that second test reads falsely high in flavored oils, and Carlson’s is lemon, so judge Carlson by peroxide. A lot report covers one batch, so look up the lot number on your bottle.

Form and fish

Form. Viva’s label and IFOS listing say re-esterified triglyceride (rTG): fish oil that was concentrated, then turned back into the form found in fish. The label Carlson filed with NIH says its omega-3s are “reported as ethyl ester,” the form most concentrated fish oil takes. Triglyceride absorbs a little better. The gap is smallest when you take fish oil with a meal that has some fat. Triglyceride vs ethyl ester.

Fish. Both use anchovy, sardine and mackerel. Viva names Peru, Chile and Morocco as the sources. Carlson’s label says “Norwegian fish oil” and “wild caught” but does not name where the fish were caught.

Carlson’s liquid vs Viva

Carlson The Very Finest Fish Oil is a lemon liquid. A teaspoon gives 800 mg EPA and 500 mg DHA, and the label says triglyceride form. IFOS lists it (CRLL0027) with 3 lot reports. At Carlson’s price, $34.90 for 200 mL (40 teaspoons), it costs $0.67 per 1,000 mg of EPA+DHA, more than Viva’s $0.30. Keep it in the fridge once open and use it within 100 days. Buy it if you don’t like swallowing softgels. Check the price.

Questions

Is Carlson fish oil third party tested?

Yes. IFOS lists Carlson Elite Omega-3 Gems (listing CRLL0014) with 1 lot report when we read it on October 27, 2026. Carlson Elite is on none of the other lists we search.

Is Viva Naturals fish oil third party tested?

Yes. IFOS lists Viva Naturals Triple Strength Omega-3 Fish Oil (listing VIVN0008) with more than 100 lot reports. Match the lot number on your bottle to the list. It is on none of the other lists we search (NSF Certified for Sport, Informed Sport, Informed Choice, NSF/ANSI 173 and USP Verified).

Which has more omega-3?

Viva. Two Viva softgels give 2,070 mg of EPA+DHA; two Carlson softgels give 1,400 mg. Skip the big number on the front of each bottle. Viva’s front counts all the fish oil. Carlson’s front counts every omega-3, not just EPA and DHA. The EPA+DHA line on the back is the one to compare.

Is Carlson Elite Omega-3 Gems triglyceride or ethyl ester?

Ethyl ester. The label Carlson filed with NIH says its omega-3s are “reported as ethyl ester.” Carlson’s website does not name a form. Viva’s label and its IFOS listing say re-esterified triglyceride (rTG).

Do they cause fishy burps?

We found no test of either for burps. Viva says its oil has “no fishy burps or aftertaste.” Carlson adds lemon flavor. Both labels say to take the softgels with a meal.

How much omega-3 should I take a day?

Studies of fish oil used about 500 to 4,000 mg of EPA+DHA a day. One Viva softgel gives about 1,035 mg; two Carlson softgels give 1,400 mg. Talk to your doctor before taking more than about 3,000 mg a day or if you take a blood thinner. Our omega-3 dosage guide covers the numbers.
