Fatty Acid
Total Omega-3 Fatty Acids
Also known as: omega-3, n-3 polyunsaturated fatty acids, n-3 PUFA, total omega-3
The collective measurement of omega-3 polyunsaturated fatty acids, including EPA (eicosapentaenoic acid), DHA (docosahexaenoic acid), and ALA (alpha-linolenic acid), which are essential fatty acids critical for cardiovascular, neurological, and inflammatory health. Supplements typically list total omega-3 content alongside individual EPA/DHA amounts.
Daily target & upper limit
500 mg / dayTotal Omega-3 Fatty Acids has an established daily reference intake. See best forms, label synonyms, upper-limit warnings, and top-scoring supplements:
Total Omega-3 Fatty Acids dosage reference →Primary uses
- cardiovascular health
- triglyceride reduction
- brain and cognitive function
- inflammatory response modulation
- eye health support
- mood and mental health
How it works
- substrate for anti-inflammatory mediator production (resolvins, protectins)
- incorporation into phospholipids in cell membranes
- modulation of gene expression related to lipid metabolism
- improvement of endothelial function
- reduction of platelet aggregation
- NLRP3 inflammasome inhibition
Dosage
- Typical range
- 500-4000 mg daily total omega-3 (composition varies: typically 300-2000 mg EPA+DHA combined)
- Timing
- with largest meal of the day
- With food
- absorption substantially improved when taken with meals containing dietary fat
- Duration
- minimum 4-12 weeks for measurable cardiovascular/triglyceride effects; long-term use (6-24 months) typically required for cognitive or anti-inflammatory outcomes
- Special populations
- pregnant/nursing women: 200-300 mg DHA daily recommended; older adults: may derive greater cardiovascular benefit; individuals with familial hypertriglyceridemia: higher doses (2-4g daily) used under medical supervision

Evidence notes
Robust RCT evidence from major cardiovascular trials; consistent meta-analyses demonstrate benefits for triglycerides and cardiovascular outcomes. EPA+DHA efficacy best established at 2-4g daily; ALA evidence more modest.
Grade A: Multiple well-designed human trials support the main claims.
