Role of n-3 long-chain polyunsaturated fatty acids in human nutrition and health: review of recent studies and recommendations
Open accessAbstract
Long-chain (LC) n-3 polyunsaturated fatty acids (n-3 PUFAs), in particular docosahexaenoic acid (DHA) and eicosapentaenoic acid (EPA), are nutrients involved in many metabolic and physiological processes, and are referred to as n-3 LCPUFA. They have been extensively studied for their effects in human nutrition and health. This paper provides an overview on metabolism, sources, dietary intake, and status of n-3 LCPUFA. A summary of the dietary recommendations for n-3 LCPUFAs for different age groups as well as specific physiological conditions is provided. Evidence for n-3 LCPUFA in cardiovascular diseases, including new studies, is reviewed. Expert recommendations generally support a beneficial effect of n-3 LCPUFA on cardiovascular health and recommend a daily intake of 500 mg as DHA and EPA, or 1-2 servings of fish per week. The role of n-3 LCPUFA on brain health, in particular neurodegenerative disorders and depression, is reviewed. The evidence for beneficial effects of n-3 LCPUFA on neurodegenerative disorders is non-conclusive despite mechanistic support and observational data. Hence, no definite n-3 LCPUFA expert recommendations are made. Data for the beneficial effect of n-3 LCPUFA on depression are generally compelling. Expert recommendations have been established: 200-300 mg/day for depression; up to 1-2 g/day for major depressive disorder. Recent studies support a beneficial role of n-3 LCPUFAs in reducing the risk for premature birth, with a daily intake of 600-800 mg of DHA during pregnancy. Finally, international experts recently reviewed the scientific evidence on DHA and arachidonic acid (ARA) in infant nutrition and concluded that the totality of data support that infant and follow-on formulas should provide both DHA and ARA at levels similar to those in breast milk. In conclusion, the available scientific data support that dietary recommendations for n-3 LCPUFA should be established for the general population and for subjects with specific physiological conditions.

TL;DR
This review summarizes n-3 LCPUFA metabolism, sources, intake/status, and expert recommendations, focusing on cardiovascular disease, brain health, pregnancy, and infant nutrition. It concludes that dietary recommendations are supported for the general population and specific physiological conditions, while evidence for neurodegenerative disorders remains non-conclusive.
Key findings
- Cardiovascular expert recommendations generally support benefit and recommend a daily intake of 500 mg DHA + EPA, or 1–2 servings of fish per week; EFSA set an adequate intake of 250 mg/day EPA + DHA for adults. In VITAL, the primary outcome was not statistically significant but showed an 8% reduction in major cardiovascular events, 28% lower total myocardial infarction, and 50% lower fatal myocardial infarction; REDUCE-IT reported that 4 g/day EPA reduced first major adverse cardiovascular events by 25% and cardiovascular death by 20%.
- For brain health, evidence for neurodegenerative disorders is non-conclusive and no definite expert n-3 LCPUFA recommendations are made; depression evidence is generally compelling, with ANSES recommending 200–300 mg/day and MDD guidelines recommending 1–2 g/day net EPA. A 2019 meta-analysis of 26 studies and 2,160 participants found an overall beneficial effect on depression symptoms, with EPA-pure and EPA-major formulations at ≤ 1 g/day showing clinical benefits.
- During pregnancy, recent studies support 600–800 mg/day DHA to reduce premature birth risk; one trial with 800 mg/day DHA reported early-preterm birth at 1.09% vs. 2.25% (P = 0.03), and another with 600 mg/day DHA reported longer gestation by 2.9 days and greater birth weight by 172 g. International experts concluded infant and follow-on formulas should provide both DHA and ARA at levels similar to breast milk.
- Globally, less than 20% of the world’s population consume ≥ 250 mg/day of seafood-origin n-3 LCPUFA; blood EPA + DHA levels were very low (≤ 4%) in North, Central, and South America, Europe, the Middle East, Southeast Asia, and Africa, and high (> 8%) in countries adjacent to the Sea of Japan, Scandinavia, and some indigenous or non-Westernized populations.
Methods
- Narrative review; no primary data collection. It provides an overview of n-3 LCPUFA metabolism, dietary sources, intake and status, and expert recommendations, then reviews recent evidence in CVD, brain health, pregnancy/prematurity, and infant nutrition.
- Evidence base includes expert reports (FAO/WHO, EFSA, IOM, NHMRC, ANSES, AHA), randomized trials (e.g., VITAL, REDUCE-IT, pregnancy DHA trials), observational studies, systematic reviews, and meta-analyses.
- Main analysis is qualitative synthesis and interpretation of cited literature; no systematic search strategy or quantitative pooling is described.
Limitations
- Stated in the paper: EPA and DHA intake estimates are limited by food composition databases and dietary reporting errors; neurodegenerative evidence is non-conclusive; clinical trials are less conclusive than observational studies; no tolerable upper intake level for n-3 LCPUFA could be established due to insufficient data; not all reviews support a beneficial role in cardiovascular health, with heterogeneity among populations, n-3 status, and intake discrepancies.
- Evident from the text: as a narrative review, it lacks a described systematic search, inclusion criteria, risk-of-bias assessment, or meta-analytic synthesis, so conclusions depend on the selected cited studies and expert interpretations.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
A language model drew the claims from the paper on 2026-10-09, under version 3 of the claim definition (model deepseek-v4.1-flash, prompt extract-v3).
A second model labelled each claim on 2026-10-09 (model jev-1.13-20260917, definition revision gold-guideline-v0.2).
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
