Why Omega-3 Matters for Mood

EPA and DHA are membrane-building fats concentrated in the brain. Adequate intake helps maintain flexible signaling, modulate inflammatory pathways, and may support antidepressant response in some individuals.

EPA/DHA integrate into membranes and influence inflammatory and neurotransmitter pathways.

Frequently Asked Questions

1) Fish vs algae-DHA — which should I choose?

If you eat fish, aim for 2 servings/week. If not, discuss algae-DHA with your clinician.

2) Can I just take ALA (flax/chia) instead?

ALA is helpful but converts poorly to EPA/DHA. Include ALA, but prioritize EPA/DHA sources.

3) What if I dislike fish?

Try canned options with sauces, fish cakes, or consider algae-DHA after discussing with your clinician.

4) Is mercury a concern?

Choose low-mercury fish (salmon, sardines, trout) and vary sources.

5) How quickly might I notice benefits?

Diet routines typically settle in 2–4 weeks. Track mood/energy KPIs to see changes.
