Omega-3 Fatty Acids (EPA/DHA)

Use an omega-3 supplement that delivers enough EPA, usually via fish oil, with a common target around 1–3 g of EPA per day and at least about 1 g/day for mood-related benefits. Many recommendations pair EPA with some DHA rather than seeking EPA-only products, and liquid fish oil is often suggested as a cost-effective way to reach the dose. The main rationale is support for mood, cognition, and brain health, with some mentions of anti-inflammatory effects and possible help for headaches or depressive symptoms.
