NOW Foods Ultra Omega-3 Review: Quality Budget Pick or Overrated? (2026)

Short Version, and What This Review Does Differently

NOW Foods Ultra Omega-3 is a concentrated fish oil delivering 500 mg of EPA and 250 mg of DHA per softgel, or 750 mg of long-chain omega-3 fatty acids in total. That is roughly two and a half times more active material than a standard fish oil capsule.

Most reviews of this product repeat the same press release. The three things they leave out are exactly the three that change your buying decision.

First: what is actually sold in Estonia is far more often NOW's standard Omega-3 line than the Ultra version, and those two are not the same product. If you buy NOW fish oil from a local shop, you are probably buying the weaker one. Second: fish oil prices cannot be compared per bottle, only per gram of EPA and DHA, and that calculation often reverses the ranking. Third: a purity certificate applies to a batch, not to a brand, and no marketing material makes that distinction.

All three are worked through below, with our own shelf prices at the time of writing.

Ultra Omega-3 and Standard NOW Omega-3 Are Not the Same Product

NOW Foods is an American manufacturer founded in Illinois in 1968 that makes a large share of its products in-house rather than ordering from a contract manufacturer. For fish oil that means molecular distillation, encapsulation and packaging happen under one roof. It is the brand's strongest argument and it is not marketing talk.

The confusion comes from the naming. In fish oil, NOW runs at least two lines of different strength at the same time.

Standard Omega-3 1000 mg. Each softgel contains 1000 mg of fish oil, of which about 180 mg is EPA and 120 mg is DHA, or 300 mg combined. This is the classic 18/12 concentration that has been the market standard for decades.

Ultra Omega-3. The same 1000 mg softgel, but concentrated: 500 mg EPA and 250 mg DHA, or 750 mg combined. That is two and a half times more active material in the same capsule.

This difference is the core of the whole article. If you take the standard version and want the amounts actually used in research, you have to swallow two and a half capsules for every one Ultra capsule. That changes both the daily capsule count and the real monthly cost.

And here is the honest part about the Estonian market. What is on our shelf at the time of writing is the standard NOW line, not Ultra. NOW Omega 3 1000mg 100 Softgels is 13.90 euros, NOW Omega 3 1000mg 200 Softgels is 20.90 euros and the 500-count bottle is 44.90 euros. The Ultra version is essentially absent from Estonian retail, and where it does appear it is usually a private import where shipping and lead time eat the price advantage. There is no point hiding that: if you came here looking specifically for Ultra, the honest answer is that you will have to do arithmetic instead.

Why 1000 mg on the Label Does Not Mean 1000 mg of Omega-3

The most common mistake at the fish oil shelf is reading the big number on the front of the box. 1000 mg is the amount of fish oil in the capsule, not the amount of EPA and DHA. The gap can be more than threefold.

The only number that matters is in the small print of the nutrition panel: EPA and DHA in milligrams per capsule. Add those two together and you have the only comparable figure. Everything else on the packaging, including the word "ultra", is a name rather than a quantity.

The same logic applies to claims like "twice as strong". Stronger than what? The only honest comparison is in milligrams of EPA and DHA.

Three practical consequences follow.

First, two products at the same bottle price can deliver completely different amounts of active material. Second, the cheaper bottle is frequently the more expensive product. Third, if your daily dose is three capsules of a weak oil, the bottle empties three times faster and the annual cost quietly triples.

Price Comparison: What a Gram of EPA and DHA Actually Costs

The calculation is simple. Multiply the capsule count by the EPA plus DHA per capsule, divide by a thousand to get grams, then divide the price by those grams.

Below it is done with our own shelf prices at the time of writing. The last row is an international reference point rather than a product we carry, and it is in the table specifically to show what concentration does to price.

Two conclusions. The larger pack is almost always cheaper per gram, and the concentrated product is cheaper even when its bottle price is higher. That is exactly why Ultra is popular internationally.

But there is a third conclusion nobody states: the large pack is only cheaper if you finish it before the oil oxidises. Five hundred capsules at one per day is nearly a year and a half. By the end of that it is not the same product you bought. Two to three months is the realistic limit. More on that immediately below.

Alternatives on our shelf

OstroVit Omega 3 Ultra 90caps is 13.90 euros and is more concentrated than the same brand's base line. Check the exact EPA and DHA figure on the label, because that number, not the capsule size, drives the calculation above.

BIOTECHUSA Mega Omega 3 90softgels is 19.90 euros and comes from a Hungarian manufacturer, which for some buyers is a meaningful argument in favour of a European supply chain.

If you are not sure whether you tolerate fish oil well, the cheapest way to find out is a small pack. OstroVit Omega 3 30caps is 3.90 euros, less than a coffee out. Buying a large tub before testing tolerance is a common way to waste thirty euros.

The full range with labels and amounts is in the omega-3 category.

Oxidation Is the Real Quality Problem With Fish Oil

The worst property of fish oil is that it goes rancid. Long-chain fatty acids are chemically unstable, and oxygen, heat and light break them down. Oxidised fish oil is not merely less useful; it is a different substance from the one you paid for.

How large the problem is was shown by an analysis carried out in New Zealand. The study tested thirty-two fish oil products on the market and found that most exceeded recommended oxidation marker limits, with 83 per cent of samples above recommended peroxide values, and that only three products contained EPA and DHA within ten per cent of their label claim (Albert et al., 2015). This is not the story of one bad brand; it is a category-wide problem.

What to do about it in practice:

Buy a pack you can finish in two to three months. A three-hundred-capsule stockpile is not a saving if half of it reaches spoilage.

Store the bottle somewhere dark and cool, not on a windowsill or next to the stove. A kitchen cupboard beats a countertop.

Vitamin E in the ingredient list is a good sign. It is an antioxidant that slows breakdown, not a filler.

If a capsule smells strongly of fish on opening, or tastes bitter, the oil has probably already degraded. Sound fish oil has a faint smell.

IFOS and Certificates: What They Actually Prove

IFOS is an independent fish oil testing programme that checks heavy metals, PCBs, dioxins, oxidation markers and whether the EPA and DHA content matches the label. A brand willing to send its products in is a good sign in itself, because the results are published.

But here is the nuance no brand emphasises. An IFOS report applies to a batch, not to a brand or a product in general. A five-star result on one 2023 lot says nothing about the bottle currently in your hand.

If the certificate matters to your buying decision, the only sensible step is to look up your lot number on the manufacturer's or the programme's site and check whether a report exists for it. If it does not, the certificate describes the brand's history rather than a property of your product.

This is not a criticism of NOW. It applies identically to every brand that advertises with a certificate, and it is the reason this review does not contain the sentence "this product is IFOS 5-star". I do not know which lot reaches you, and neither does any other review that writes that sentence.

How Much EPA and DHA per Day Is Reasonable

EFSA has set a dietary reference value of 250 mg of EPA and DHA per day for adults (EFSA, 2010). That is covered by one standard fish oil capsule, or roughly two portions of oily fish a week. It is a baseline, not the level used in studies.

The amounts used in research are typically substantially higher, often in the range of one to two grams of EPA and DHA per day. Reaching that with the standard NOW line means three to seven capsules a day, which makes the price calculation above look completely different. With Ultra capsules the same amount would be one to three. This is exactly where the concentration difference turns into money.

How do you know whether your level is low at all? The Omega-3 Index is a blood test measuring EPA and DHA as a proportion of red blood cell fatty acids (Harris & von Schacky, 2004). Unlike how you feel, it is a number you can measure before and after. Several private laboratories in Estonia offer it, and it is the only way to stop guessing.

Why does the amount matter at all? EPA and DHA do not act like a drug that works an hour after you take it. They are built into cell membranes, where they change the fatty acid composition of the membrane and the profile of signalling molecules derived from it (Calder, 2015). Changing membrane composition takes weeks. A two-week course shows nothing, and that is the single most common reason people abandon fish oil.

How to Take It So It Absorbs, and What to Do About Fishy Burps

Fish oil absorption depends on whether there is fat in the digestive tract at the same time. A review of the bioavailability of long-chain omega-3 fatty acids shows that taking them with a fat-containing meal increases absorption substantially compared with taking them on an empty stomach (Schuchardt & Hahn, 2013).

The practical rule is simple. Take the capsules in the middle of lunch or dinner, not with your morning coffee. If your lunch is an undressed salad or a piece of fruit, that is not a good place for fish oil.

The clock time itself does not matter. Splitting the dose starts to matter above three capsules a day, where dividing between two meals is better for both tolerance and absorption.

Fishy burps arise mainly for two reasons: the capsule dissolves too early in the stomach, or the oil is already partly oxidised. What helps: taking the capsule mid-meal rather than at the start; keeping the bottle in the fridge, because a cold capsule dissolves more slowly; and switching product if the problem persists, because it is often specific to a batch. What does not help: splitting the capsule, washing it down with a lot of water, or hoping that taking it at night means you will not notice.

The Estonian Context: Winter, Fish and Vitamin D

In Estonia the case for fish oil is stronger than it is on the Mediterranean, and the reason is not only that people here eat less oily fish than in Norway.

A population-based Estonian study found clear seasonal variation in vitamin D levels, markedly lower in the winter months than in summer (Kull et al., 2009). Omega-3 and vitamin D are different things and one must not be substituted for the other, but in an Estonian winter they fall into the same hole. Oily fish intake drops, there is no sun, and neither improves on its own between December and March.

The practical conclusion is dull and true: if you are going to take a supplement over winter anyway, it is sensible to look at both at once rather than buy three things in three separate months. The interaction between vitamin D, K2 and omega-3 is written up separately here: D3, K2 and omega-3. On the vitamin side, the range is in the vitamin complexes category.

One more local point worth saying out loud. On an Estonian pharmacy shelf, fish oil is often more expensive per gram of EPA and DHA than the sports shop equivalent, because pharmacy capsules are frequently weaker. That is not a quality difference, it is a concentration difference, and it is the one place where the calculation above genuinely saves you money.

Who Should Skip This Product

Fish oil is not a universal purchase, and the honest list is short.

Vegans and vegetarians. The active material comes from fish and the capsule shell is usually gelatin. The only serious alternative is algal oil, which costs more but supplies DHA straight from the source.

Anyone with a fish allergy. Obvious, but worth repeating, because the product name does not always contain the word fish.

Anyone already prescribed treatment affecting blood clotting, or with surgery scheduled. Starting larger doses in that situation is a conversation with your doctor, not a decision to make alone.

Pregnant and breastfeeding women. DHA matters in that period, but the choice of product and dose belongs with a midwife or doctor, because not every fish oil is intended for it.

Anyone who wants one capsule that covers everything. This product contains no vitamin D and nothing beyond fish oil.

And the most practical point: anyone who does not intend to take it for at least three consecutive months. Membrane composition does not change faster than that, and a shorter course is money that went into capsules rather than into a result.

FAQ

Is NOW Ultra Omega-3 available in Estonia?

What is on our shelf at the time of writing is the standard NOW Omega-3 1000 mg line, not the Ultra version. Ultra is generally absent from Estonian retail. If you see it offered somewhere, check the label for whether the capsule really contains 500 mg EPA and 250 mg DHA, because the names are similar and the mix-up is common.

How many standard NOW Omega-3 capsules equal one Ultra capsule?

About two and a half. Ultra provides 750 mg of EPA and DHA per capsule, the standard line 300 mg. Two and a half standard capsules give 750 mg, which in practice means two or three.

Is more expensive fish oil always purer?

No. Price and purity are not proportional. Purity can only be verified through a batch test report, and the oxidation problem was found widely across the whole price range in the study cited above (Albert et al., 2015). Price more often reflects concentration and packaging than purity.

Does fish oil have to be kept in the fridge?

It is not mandatory, but it helps in two ways: it slows oxidation and reduces fishy burps, because a cold capsule dissolves more slowly in the stomach. What you should definitely avoid is storing it on a windowsill or anywhere warm.

How long do I need to take it before anything shows?

The fatty acid composition of membranes changes over weeks, not days (Calder, 2015). A realistic assessment period is three months, and the only objective measure is an Omega-3 Index test before and after (Harris & von Schacky, 2004).

Are expensive test-and-supplement systems better than plain fish oil?

The blood test is useful, but you can order it separately and usually more cheaply. The pricing structure of one such system is taken apart separately here: Zinzino BalanceOil review. A look at the budget end is here: Mivolis Omega-3 1000.
