Is NOW Foods Ultra Omega-3 Good? Nutrition & Benefits

The National Center for Complementary and Integrative Health (NCCIH) reviewed 23 studies with nearly 44,000 participants and found that EPA and DHA from marine sources lower triglycerides by roughly 15% on average. The NIH Office of Dietary Supplements quantifies this further: each 1 gram per day increase in long-chain omega-3s reduces triglycerides by about 5.9 mg/dL. This effect is dose-dependent and well-replicated, making it the most reliable reason to take a concentrated fish oil like NOW Foods Ultra Omega-3.

The anti-inflammatory evidence is moderate and more condition-specific. Mayo Clinic notes that fish oil can reduce joint stiffness and tenderness in rheumatoid arthritis, but the response varies significantly with dose, duration, and individual factors. It's not a universal anti-inflammatory — it works for some inflammatory pathways but not others, and the effect size is modest compared to pharmacological interventions.

Cardiovascular event reduction from fish oil supplements is where the evidence gets genuinely mixed. While eating oily fish twice a week is consistently associated with lower cardiovascular risk in observational studies, supplement trials have been far less impressive. The REDUCE-IT trial showed clear benefit from high-dose prescription EPA (icosapentaenoic acid, brand name Vascepa), but that's a pharmaceutical-grade, highly purified EPA at 4 grams per day — not an over-the-counter fish oil supplement. Most OTC fish oil trials for heart attack and stroke prevention have been neutral or weakly positive. The supplement is not a substitute for the complex nutritional matrix of actual fish.

And then there's the claim that virtually every consumer fish oil article includes but shouldn't: weight loss. The NCCIH 2020 review is explicit — EPA and DHA 'do not affect body fat.' This finding comes from the same large body of evidence that established the triglyceride benefit. Omega-3s are not thermogenic, they don't meaningfully suppress appetite, and they don't increase metabolic rate. Any article implying fish oil helps with fat loss is either misreading the evidence or deliberately misleading readers. This is the single biggest gap between what consumers are told and what the data actually show.

The practical concern is entirely about tolerability. GLP-1 medications slow gastric emptying as part of their mechanism — that's one reason they reduce appetite and can cause nausea. Adding a fish oil supplement that sits in the stomach and potentially causes reflux means you're layering one GI irritant on top of a medication that already challenges GI comfort. The enteric-coated formulation solves this by delivering the oil past the stomach, but if you're using standard softgels, timing matters: take them with your largest meal of the day, not on an empty stomach or with a light snack.

There's also a positive case for omega-3 supplementation during GLP-1 therapy that goes beyond triglyceride numbers. Many people prescribed GLP-1 medications are managing cardiometabolic risk — obesity, type 2 diabetes, dyslipidemia, hypertension. The triglyceride-lowering effect of EPA and DHA addresses one component of that risk profile independently of weight loss. As body weight drops on a GLP-1 medication, lipid panels often improve, but the addition of omega-3s may provide incremental triglyceride reduction that complements the medication's effects. This is not a substitute for the GLP-1 drug — it's an adjunct that targets a specific lipid parameter the medication may not fully normalize on its own.

If you're using a GLP-1 medication and considering NOW Foods Ultra Omega-3, the enteric-coated version taken with a meal is the formulation most likely to deliver the cardiovascular benefits without adding to the nausea burden. Start with one softgel daily and assess tolerability before increasing the dose.
