Quick Answer: The Best Omega-3 Supplements for 2026

Omega-3 is the single most universally recommended supplement across the longevity experts we track — five out of six take it daily. The reason is simple: the evidence base for EPA and DHA spans cardiovascular health, brain function, mood regulation, and systemic inflammation. Our top picks are ranked by EPA+DHA per serving, third-party purity testing (IFOS certification preferred), triglyceride form, and real-world expert use. Carlson’s and Nordic Naturals lead for overall quality, while Sports Research offers the best value.

How We Evaluate Omega-3 Supplements

Not all omega-3 supplements are created equal — and the differences between a high-quality fish oil and a low-quality one are more significant than most people realize. Oxidized, poorly concentrated fish oil can be ineffective or even counterproductive. Here is exactly what we evaluate.

EPA + DHA Content Per Serving

This is the number that matters — not “total omega-3” on the front label. Many supplements advertise 1,000 mg of fish oil but only deliver 300 mg of combined EPA and DHA. The rest is other fatty acids your body does not need to supplement. We prioritize products that deliver at least 1,000 mg of combined EPA+DHA per serving because that aligns with the dosing ranges discussed by researchers like Dr. Andrew Huberman (who has mentioned targeting 2-3g EPA per day) and Dr. Rhonda Patrick.

IFOS Certification and Third-Party Testing

The International Fish Oil Standards (IFOS) program independently tests omega-3 products for potency, purity, and freshness. An IFOS 5-star rating means the product passed testing for:

• Heavy metals (mercury, lead, arsenic, cadmium) below strict thresholds
• PCBs and dioxins below detectable limits
• Oxidation markers (peroxide value, anisidine value, TOTOX) confirming freshness
• Potency matching or exceeding label claims

NSF Certified for Sport is another strong credential, particularly relevant for products used by athletes or endorsed by physician-oriented brands like Thorne.

Triglyceride vs. Ethyl Ester Form

The molecular form of an omega-3 supplement affects how well your body absorbs it. We strongly prefer triglyceride (TG) form over ethyl ester (EE) form, and we explain why in detail below.

Oxidation and Freshness

Omega-3 fatty acids are vulnerable to oxidation. An oxidized fish oil supplement may smell or taste rancid and could promote rather than reduce inflammation. We check for:

• TOTOX value (total oxidation) — lower is better, ideally under 10
• Packaging — dark bottles or blister packs protect against light oxidation
• Manufacturing transparency — brands that disclose their supply chain and processing timeline

Value Per Milligram of EPA+DHA

Price per bottle is misleading. A $15 bottle with 300 mg EPA+DHA per serving costs more per effective milligram than a $35 bottle with 1,500 mg per serving. We calculate value based on cost per 1,000 mg of combined EPA+DHA at standard dosing.

Detailed Omega-3 Supplement Reviews

1. Carlson’s The Very Finest Fish Oil — Best Overall (Huberman’s Pick)

Overview: Carlson’s has been a recognized name in fish oil supplementation for decades, but what put them on the longevity community’s radar is Dr. Andrew Huberman’s public mention of the brand. On multiple episodes of the Huberman Lab podcast, Huberman has discussed taking a liquid fish oil from Carlson’s, noting the high EPA content and the fact that it is IFOS-certified. That kind of specific, unprompted mention from a neuroscientist carries significant weight.

EPA+DHA Per Serving: 1,600 mg per tablespoon (liquid form) — 800 mg EPA, 800 mg DHA. This is one of the highest concentrations available without prescription.

Form: Triglyceride — the natural, more bioavailable form.

Third-Party Testing: IFOS 5-star rated. Carlson’s publishes batch-specific test results and maintains transparency about their Norwegian fish oil sourcing.

Taste and Usability: Available in natural lemon flavor (liquid) and softgels. The liquid version is genuinely palatable — no heavy fish taste or aftertaste. The softgel option delivers less EPA+DHA per serving (roughly 800 mg per two softgels) but avoids the liquid format some people dislike.

Pricing: Liquid (16.9 oz, ~100 servings): approximately $28-35, making it one of the best values per milligram of EPA+DHA on the market. Softgels are pricier per serving.

What I Actually Buy

I run a high-dose omega-3 protocol — over 3g of combined EPA/DHA daily — so concentration matters more to me than brand loyalty. I’ve tried cheap fish oil from the grocery store and premium brands. The difference comes down to two things: how many capsules you need to hit your target dose, and whether you get fish burps. Higher concentration means fewer pills and fewer burps. I cover my full omega-3 protocol in the omega-3 deep dive article.

I test and compare the supplements I actually take. The CoreStacks Longevity Report — free, weekly.

Pros:

• Highest EPA+DHA per serving in liquid form
• IFOS 5-star certified with batch-specific testing
• Mentioned by Huberman as his fish oil of choice
• Excellent value per milligram of EPA+DHA
• Pleasant lemon flavor in liquid form
• Long track record — Carlson’s has been producing fish oil since 1982

Cons:

• Liquid form requires refrigeration after opening
• Softgel version delivers less EPA+DHA per serving
• Not as widely available in retail stores as Nordic Naturals
• Liquid format is not ideal for travel

Bottom Line: If you want the fish oil that a Stanford neuroscientist publicly uses, with top-tier purity testing and one of the best value propositions on the market, Carlson’s liquid is hard to beat. It is our top overall recommendation.

2. Nordic Naturals Ultimate Omega — Best Widely Available Option

Overview: Nordic Naturals is arguably the most recognized omega-3 brand in the United States, and their Ultimate Omega product is the most popular concentrated omega-3 supplement in the country. Dr. Brad Stanfield has mentioned Nordic Naturals as a reputable brand in his evidence-based supplement discussions, and Dr. Rhonda Patrick has referenced their products when discussing omega-3 quality standards.

EPA+DHA Per Serving: 1,280 mg per two softgels — 650 mg EPA, 450 mg DHA. Solid concentration, though not the highest on this list.

Form: Triglyceride — Nordic Naturals was one of the early advocates for TG-form fish oil and has built their brand around it.

Third-Party Testing: IFOS 5-star rated. Also tested by the European Pharmacopoeia and Council for Responsible Nutrition standards. Nordic Naturals exceeds international standards for freshness and purity.

Taste and Usability: Lemon-flavored softgels. Minimal fishy burps compared to ethyl ester products. Also available in liquid form.

Pricing: 120 softgels (60 servings, two-month supply): approximately $55-65 retail, working out to roughly $30-35 per month.

Pros:

• IFOS 5-star with additional third-party certifications
• Available in virtually every health food store, pharmacy, and online retailer
• Friend of the Sea certified for sustainable sourcing
• Strong reputation in the clinical and practitioner community
• Multiple formulations available (ProOmega, ProEPA, children’s)

Cons:

• More expensive per milligram of EPA+DHA than Carlson’s liquid
• Two softgels needed per serving — four per day if targeting 2,500 mg EPA+DHA
• EPA-to-DHA ratio favors EPA but not as strongly as Thorne Super EPA

Bottom Line: Nordic Naturals is the safe, reliable choice. If you want a brand your doctor has heard of, that is available at your local store, with rock-solid testing credentials, Ultimate Omega delivers.

3. Thorne Super EPA — Best for High-EPA Focus

Overview: Thorne is a physician-grade supplement company trusted by medical professionals, and their Super EPA product is designed for people specifically targeting higher EPA intake. Peter Attia has a well-known partnership with Thorne and has discussed fish oil as a core component of his longevity protocol on The Drive podcast. While Attia has not publicly specified which exact Thorne omega-3 product he uses, the Super EPA aligns with his stated emphasis on EPA for cardiovascular and inflammatory support.

EPA+DHA Per Serving: 1,100 mg per two softgels — 750 mg EPA, 350 DHA. The EPA-heavy ratio makes this a strong choice for those targeting inflammation and mood support, as discussed in the EPA vs. DHA section below.

Form: Triglyceride — pharmaceutical grade.

Third-Party Testing: NSF Certified for Sport, which means it is independently tested for banned substances and label accuracy. This is one of the more rigorous certifications available.

Taste and Usability: Small, easy-to-swallow gelcaps with minimal odor. Thorne’s manufacturing quality control means very few reports of fishy burps or aftertaste.

Pricing: 90 gelcaps (45 servings, approximately 1.5 months): $42-50, working out to roughly $35-40 per month. Premium pricing.

Pros:

• NSF Certified for Sport — one of the strictest testing certifications
• High EPA-to-DHA ratio ideal for inflammation and mood protocols
• Trusted by physicians and longevity practitioners
• Thorne’s manufacturing standards are pharmaceutical-grade
• Small, easy-to-swallow gelcaps

Cons:

• The most expensive option per milligram of EPA+DHA on this list
• Lower total EPA+DHA per serving than Carlson’s or Momentous
• Available primarily online — limited retail distribution
• Thorne products require practitioner code for best pricing

Bottom Line: Thorne Super EPA is for the person who wants physician-grade quality and is specifically targeting high EPA intake. If your protocol prioritizes EPA (as Attia’s and Huberman’s discussions suggest), this is a top-tier choice — just be prepared to pay for it.

4. Momentous Omega-3 — Best for Huberman Lab Listeners

Overview: Momentous has become closely associated with the Huberman Lab podcast through an ongoing partnership. Dr. Huberman has discussed Momentous products extensively, and their omega-3 formulation was reportedly developed with input from researchers focused on optimal EPA+DHA delivery. It is worth noting that this is a brand partnership — Huberman has a financial relationship with Momentous. We mention this because transparency matters, though it does not diminish the product quality.

EPA+DHA Per Serving: 1,500 mg per two softgels — 900 mg EPA, 600 mg DHA. Strong EPA concentration with meaningful DHA.

Form: Triglyceride — sourced from wild-caught fish.

Third-Party Testing: NSF Certified for Sport. Third-party tested for heavy metals, PCBs, and oxidation markers.

Taste and Usability: Standard softgels, lemon-coated to reduce fishy aftertaste. Well-tolerated based on community feedback.

Pricing: 60 softgels (30 servings, one-month supply): approximately $40-45. This makes Momentous one of the pricier options, but the per-serving EPA+DHA content partially offsets the cost.

Pros:

• High EPA+DHA per serving — 1,500 mg per two softgels
• NSF Certified for Sport
• Formulated with research-oriented dosing in mind
• Convenient one-month supply packaging
• Well-integrated with Huberman Lab protocol information

Cons:

• Brand partnership with Huberman means endorsement is not purely independent
• Premium pricing compared to Carlson’s or Sports Research
• Relatively new brand — less long-term track record than Carlson’s or Nordic Naturals
• Only available direct from Momentous website

Bottom Line: If you follow Huberman’s protocols and want a product designed around the dosing ranges he discusses, Momentous is a convenient, high-quality choice. Just factor in the brand-partnership context and compare value per milligram against Carlson’s liquid.

5. Sports Research Triple Strength — Best Budget Option

Overview: Sports Research does not have the expert endorsement profile of Carlson’s or the physician reputation of Thorne, but their Triple Strength omega-3 consistently delivers strong purity testing at a price point that makes high-quality fish oil accessible. For readers who want IFOS-certified omega-3 without paying premium brand pricing, this is the product we recommend.

EPA+DHA Per Serving: 1,040 mg per one softgel — 690 mg EPA, 350 mg DHA. The single-softgel serving is a real advantage for simplicity.

Form: Triglyceride — clearly labeled on the bottle, which not all budget brands do.

Third-Party Testing: IFOS 5-star rated. Also carries the Marine Stewardship Council (MSC) certification for sustainable sourcing.

Taste and Usability: Enteric-coated softgels designed to dissolve in the intestine rather than the stomach, significantly reducing fishy burps. Single softgel per serving is a major convenience advantage.

Pricing: 180 softgels (six-month supply): approximately $25-30, which works out to $4-5 per month. This is by far the best value on this list.

Pros:

• IFOS 5-star certified — same testing standard as Carlson’s and Nordic Naturals
• Single softgel per serving (most competitors require two)
• Extraordinary value — roughly $0.15 per day at single-serving dosing
• MSC certified for sustainable sourcing
• Enteric coating reduces fishy burps effectively
• Widely available on Amazon with strong review history

Cons:

• No specific longevity expert endorsements
• Lower EPA+DHA per serving than Carlson’s liquid or Momentous
• Would need two softgels per day to approach 2,000+ mg EPA+DHA targets
• Less brand prestige than physician-grade options

Bottom Line: Sports Research Triple Strength is the omega-3 we recommend for people who want proven quality (IFOS 5-star) at a fraction of the premium brand cost. If budget is a factor, start here.

6. Kori Krill Oil Mind & Body — Best Krill Oil Option

Overview: Krill oil operates differently from fish oil. While it delivers EPA and DHA, the omega-3s in krill oil are bound to phospholipids rather than triglycerides, which some research suggests may enhance absorption — particularly into cell membranes and potentially across the blood-brain barrier. Dr. Rhonda Patrick has discussed the unique properties of krill oil-derived omega-3s, particularly the phospholipid-bound DHA and the naturally occurring antioxidant astaxanthin.

EPA+DHA Per Serving: 600 mg per two softgels — 300 mg EPA, 150 mg DHA, plus 150 mg of other omega-3s. Also provides 750 mcg of astaxanthin, a potent carotenoid antioxidant.

Form: Phospholipid-bound — this is the key differentiator from fish oil.

Third-Party Testing: MSC-certified sustainable Antarctic krill sourcing. Third-party tested for contaminants and potency.

Taste and Usability: Smaller softgels than standard fish oil. Virtually no fishy aftertaste — this is one of krill oil’s genuine advantages.

Pricing: 120 softgels (60 servings, two-month supply): approximately $55-65, or $30-35 per month. More expensive per milligram of EPA+DHA than any fish oil on this list, but the phospholipid form and astaxanthin content change the comparison.

Pros:

• Phospholipid-bound omega-3s for potentially enhanced membrane absorption
• Natural astaxanthin content (antioxidant)
• Virtually no fishy aftertaste or burps
• Smaller softgels than fish oil options
• MSC-certified sustainable sourcing

Cons:

• Significantly lower EPA+DHA per serving than fish oil options
• More expensive per milligram of EPA+DHA
• Not suitable for anyone with shellfish allergies
• Harder to reach 2,000+ mg EPA+DHA targets discussed by longevity experts
• Less extensive research base than fish oil

Bottom Line: Krill oil is not a direct replacement for high-dose fish oil in a longevity protocol. But if you struggle with fish oil tolerance, want the antioxidant benefits of astaxanthin, or are specifically interested in the phospholipid-bound absorption angle, Kori is a quality krill oil option. Consider it as a complement to, not a substitute for, concentrated fish oil. See our fish oil vs. krill oil comparison below for the full breakdown.

EPA vs. DHA: What Matters for What

EPA (eicosapentaenoic acid) and DHA (docosahexaenoic acid) are both omega-3 fatty acids, but they serve different primary roles in the body. Understanding the distinction helps you choose the right product for your goals.

EPA: Inflammation and Mood

EPA is the omega-3 most strongly associated with anti-inflammatory effects and mood regulation. Key research findings discussed by experts include:

• Dr. Andrew Huberman has discussed EPA’s role in modulating neuroinflammation on the Huberman Lab podcast, citing research suggesting that 1,000-2,000 mg of EPA per day may support mood and be relevant in the context of depression research. He has noted that higher EPA-to-DHA ratios may be more impactful for mood-related outcomes.
• Meta-analyses published in journals including Translational Psychiatry and JAMA Network Open have found that omega-3 supplements with higher EPA content showed more consistent effects in studies on depressive symptoms than those with higher DHA content.
• EPA competes with arachidonic acid for enzymatic conversion, which is a mechanism by which it may reduce pro-inflammatory eicosanoid production.

If your primary goals are mood support or managing inflammation, prioritize EPA. Thorne Super EPA and Momentous Omega-3 both offer EPA-dominant ratios.

DHA: Brain Structure and Eyes

DHA is a structural component of the brain and retina. It makes up a significant portion of the omega-3 fatty acids in neural tissue and is critical for:

• Dr. Rhonda Patrick has extensively discussed DHA’s role in brain health on FoundMyFitness, emphasizing that DHA is essential for neuronal membrane fluidity and that low DHA status is associated with cognitive decline in aging populations. She has been particularly vocal about DHA’s importance during pregnancy and early development.
• DHA constitutes approximately 40% of the polyunsaturated fatty acids in the brain and approximately 60% in the retina.
• Research published in Alzheimer’s & Dementia has explored associations between higher omega-3 index (a measure that includes both EPA and DHA levels) and brain volume in older adults.

If your primary goals are cognitive longevity and brain health, ensure adequate DHA. Carlson’s liquid provides a balanced 1:1 EPA-to-DHA ratio that covers both bases.

The Practical Answer

Most longevity experts do not obsess over the EPA-to-DHA ratio in isolation. They focus on getting enough total EPA+DHA — typically in the range of 2,000-3,000 mg combined per day. At that total intake, you are getting meaningful amounts of both. If you have a specific goal (mood support = more EPA; brain/eye health = ensure DHA is adequate), you can bias your product choice accordingly.

Triglyceride vs. Ethyl Ester: What Experts Recommend

This is one of the most important quality distinctions in omega-3 supplements, and most buyers do not know to check for it.

What Is the Difference?

• Triglyceride (TG) form: The natural form of omega-3 as it exists in fish. Three fatty acid chains attached to a glycerol backbone. This is how your body is designed to absorb dietary fats.
• Ethyl ester (EE) form: A synthetic form created during the concentration process. One fatty acid chain attached to an ethanol molecule. Cheaper to produce at high concentrations.

Why It Matters

Research published in journals including Prostaglandins, Leukotides and Essential Fatty Acids has shown that triglyceride-form omega-3s demonstrate meaningfully higher bioavailability compared to ethyl ester form. Dr. Rhonda Patrick has discussed this distinction and has noted her preference for the triglyceride form.

Key differences:

Factor	Triglyceride (TG)	Ethyl Ester (EE)
Bioavailability	Higher — absorbed more efficiently	Lower — requires additional enzymatic step
Food requirement	Absorbed well with or without food	Requires high-fat meal for adequate absorption
Oxidation resistance	More stable	More susceptible to oxidation
Cost	More expensive to produce	Cheaper to produce
Expert preference	Recommended by Patrick, Stanfield	Not specifically recommended by any expert we track

How to Check

Look at the Supplement Facts panel on the back of the bottle. If it says “fish oil (as triglycerides)” or “triglyceride form,” you are good. If it says “fish oil concentrate (ethyl ester)” or does not specify, assume ethyl ester. All six products on our list are triglyceride form — we consider it a baseline requirement.

---

How to Read an Omega-3 Label

The front of an omega-3 bottle is marketing. The Supplement Facts panel on the back is where the truth lives. Here is what to look for:

Step 1: Ignore “Total Fish Oil” — Find EPA + DHA

A supplement may say “1,000 mg Fish Oil” on the front. Flip it over. What matters is the EPA and DHA breakdown:

• Good: 1,000 mg fish oil containing 600 mg EPA + 400 mg DHA = 1,000 mg EPA+DHA
• Bad: 1,000 mg fish oil containing 180 mg EPA + 120 mg DHA = 300 mg EPA+DHA

That second product would require three to four servings per day to reach 1,000 mg EPA+DHA. Many inexpensive fish oils sold in bulk at warehouse stores fall into this category.

Step 2: Check the Serving Size

Is the serving one softgel or two? Some brands list impressive numbers per “two softgels” — which doubles your actual consumption rate and cost.

Step 3: Look for Form Disclosure

“Triglyceride form” or “TG” should be stated somewhere on the label or product page. If it is not mentioned, the product is likely ethyl ester.

Step 4: Find Third-Party Certifications

IFOS 5-star, NSF Certified for Sport, USP, or ConsumerLab seals indicate independent testing. A brand’s own “purity tested” claim without independent verification is marketing, not evidence.

Step 5: Check for Additional Ingredients

Some omega-3 products include added vitamin D, vitamin E (as a natural antioxidant to prevent oxidation — this is fine), or lemon/orange oil for flavor. Avoid products with a long list of artificial ingredients, fillers, or unnecessary additives.

---

How Much Omega-3 Do You Need? What Experts Take

Omega-3 dosing is one of the more convergent topics among longevity experts — most land in a similar range, which is notably higher than the typical supplement label’s “suggested use.”

Expert Dosing Overview

Expert	Reported Daily EPA+DHA	Notes
Andrew Huberman	~2,000-3,000 mg, emphasizing EPA	Has discussed targeting 2g+ EPA for mood and inflammation support on the Huberman Lab podcast
Peter Attia	~2,000+ mg (estimated)	Includes fish oil as a core supplement in his longevity framework, as discussed on The Drive
Rhonda Patrick	~2,000+ mg, emphasizing DHA importance	Extensive FoundMyFitness content on omega-3 index testing and DHA for brain health
Brad Stanfield	~2,000 mg	Includes omega-3 in his evidence-based longevity supplement list on YouTube

The Practical Range

Based on expert protocols and published research, the range most commonly discussed in the longevity community is:

• Minimum effective: 1,000 mg combined EPA+DHA per day
• Common expert range: 2,000-3,000 mg combined EPA+DHA per day
• Upper range discussed: 3,000-4,000 mg EPA+DHA per day (typically under physician supervision with blood work monitoring)

The Omega-3 Index

Dr. Rhonda Patrick has been a prominent advocate for testing your omega-3 index — a blood test that measures the percentage of EPA and DHA in your red blood cell membranes. An omega-3 index of 8-12% is considered optimal based on cardiovascular research. Most Americans test below 4-5%. This is one area where testing can directly inform your dosing decisions rather than guessing. The test is available through services like OmegaQuant.

Fish Oil vs. Krill Oil vs. Algae Oil

This is one of the most common questions in the omega-3 space, and the answer depends on your priorities.

Factor	Fish Oil	Krill Oil	Algae Oil
EPA+DHA per serving	High (1,000-1,600 mg)	Low-moderate (300-600 mg)	Moderate (400-800 mg, DHA-dominant)
Form	Triglyceride	Phospholipid	Triglyceride
Absorption	Well-absorbed in TG form	Potentially enhanced via phospholipid delivery	Well-absorbed
Additional benefits	—	Astaxanthin (antioxidant)	Vegan/vegetarian, no ocean contaminant risk
Cost per mg EPA+DHA	Lowest	Highest	Moderate
Sustainability	Varies by source	Generally sustainable (Antarctic krill managed)	Most sustainable — no fishing required
Allergen concern	Fish allergy	Shellfish allergy	None
Best for	High-dose protocols, best value	People who cannot tolerate fish oil, want astaxanthin	Vegans, vegetarians, those avoiding fish products

Fish Oil: The Default Choice for Longevity Protocols

Fish oil remains the standard recommendation among the longevity experts we track because it offers the highest EPA+DHA per serving at the best value. If you are targeting the 2,000-3,000 mg per day range most experts discuss, fish oil makes this achievable with one to two servings per day. Krill oil would require four to six capsules daily to approach the same intake.

Krill Oil: A Niche Option with Unique Properties

Krill oil’s phospholipid-bound omega-3s are an interesting delivery mechanism, and the included astaxanthin provides antioxidant value. However, the lower EPA+DHA per serving makes it impractical as a sole omega-3 source for high-dose protocols. Some people use krill oil alongside fish oil for the phospholipid diversity and astaxanthin.

Algae Oil: The Plant-Based Alternative

For vegans, vegetarians, or anyone who wants to avoid fish-derived products, algae oil is the answer. Algae is where fish get their omega-3s in the first place — fish do not produce EPA and DHA, they accumulate it from eating algae and smaller organisms that eat algae. Algae oil tends to be DHA-dominant, which is relevant for brain health but may require supplementation with an EPA source for anti-inflammatory protocols. Brands like Nordic Naturals Algae Omega offer options in this category.

Frequently Asked Questions

When should I take omega-3 supplements?

Dr. Andrew Huberman has discussed taking omega-3 supplements with meals, particularly meals containing dietary fat, to enhance absorption. This is especially important for ethyl ester forms (which we do not recommend), but even triglyceride-form omega-3s are absorbed best alongside a meal. Morning or evening does not matter for efficacy — consistency matters more than timing.

Can I get enough omega-3 from food instead of supplements?

It depends on your diet. Fatty fish like wild salmon, mackerel, sardines, and anchovies are excellent sources of EPA and DHA. Two to three servings of fatty fish per week may provide sufficient omega-3 for some people. However, most longevity experts who target 2,000+ mg of EPA+DHA daily find supplementation more practical and consistent than relying solely on dietary intake. Dr. Rhonda Patrick has discussed how even regular fish consumers often test below optimal omega-3 index levels.

What is the difference between omega-3, omega-6, and omega-9?

These refer to different families of fatty acids defined by the position of their first double bond. Omega-3 (EPA, DHA, ALA) and omega-6 (linoleic acid, arachidonic acid) are essential — your body cannot produce them. Omega-9 (oleic acid, found in olive oil) is non-essential. The modern Western diet typically provides excessive omega-6 relative to omega-3, which some researchers, including Dr. Rhonda Patrick, have discussed as a factor in chronic inflammation. Supplementing omega-3 can help rebalance this ratio.

Are there side effects from omega-3 supplements?

Common, generally minor side effects reported include fishy aftertaste or burps (less common with TG-form and enteric-coated softgels), mild digestive discomfort at high doses, and potential for slightly increased bleeding time. The bleeding concern is most relevant for people on blood-thinning medications or approaching surgery. Dr. Peter Attia has discussed monitoring blood work when taking high-dose omega-3 supplementation as part of a comprehensive health protocol.

How do I know if my omega-3 supplement is rancid?

Smell it. Seriously. Cut open a softgel or smell the liquid — fresh fish oil should have a mild, slightly oceanic or citrus scent (if flavored). A strong, unpleasant fishy smell indicates oxidation. Check the expiration date, store your fish oil in a cool, dark place (refrigerate liquid forms after opening), and buy from brands with IFOS certification, which includes oxidation testing.

Is 1,000 mg of fish oil the same as 1,000 mg of omega-3?

No — and this is one of the most common sources of confusion. 1,000 mg of fish oil refers to the total oil in the capsule, which includes EPA, DHA, and other fatty acids. The EPA+DHA content may be only 300-500 mg of that total. Always check the Supplement Facts panel for the EPA and DHA breakdown, not the front-of-bottle “fish oil” number. See our label-reading guide above for details.

Do I need to take omega-3 if I already eat fish regularly?

Possibly not, but the only way to know is testing. The omega-3 index blood test (discussed by Dr. Rhonda Patrick) measures your actual EPA and DHA status. Even regular fish consumers sometimes test below the 8% threshold considered optimal. If you eat fatty fish three or more times per week, your needs may be met through diet alone. If you eat fish once a week or less, supplementation is likely warranted based on the expert discussions we track.

Should I choose a higher EPA or higher DHA supplement?

This depends on your primary goals. For mood and inflammation support, research discussed by Dr. Huberman suggests prioritizing EPA. For cognitive health and brain structure, Dr. Patrick emphasizes adequate DHA. For general longevity and health maintenance, a balanced ratio (like Carlson’s 1:1 EPA:DHA) covers both bases. Most experts focus on total intake of 2,000+ mg combined EPA+DHA per day rather than obsessing over the ratio. See our EPA vs. DHA section above for the full breakdown.
