Key Evidence Takeaways:
- EPA competes directly with arachidonic acid to suppress inflammatory 2-series prostaglandins, dramatically easing painful menstrual cramps.
- Therapeutic doses of EPA and DHA (2,000–3,000 mg) lower circulating triglycerides by 20% to 30% and reduce cardiovascular events in women.
- DHA forms over 90% of brain polyunsaturated fatty acids, supporting postpartum mood and hippocampal volume in aging.
- Target an Omega-3 Index of greater than 8% for optimal cardioprotective and neuroprotective resilience.
Frequently Asked Questions
Can omega-3 help with menstrual cramps?
Yes! Clinical trials have found that 1,000 to 2,000 mg/day of high-EPA omega-3 fatty acids can be as effective as ibuprofen for reducing primary dysmenorrhea pain by downregulating uterine prostaglandins.
How long does it take for omega-3 to improve dry eyes?
Because fatty acids must integrate into the lipid layer of the meibomian glands, noticeable improvement in tear film stability and dry eye irritation typically takes 6 to 12 weeks of consistent supplementation.
