Omega-3

Snapshot

Omega‑3 fatty acids are essential polyunsaturated fats—primarily EPA, DHA, and ALA—that support cardiovascular, cognitive, and inflammatory health.

 

---

What is Omega‑3?

Omega‑3s are long‑chain polyunsaturated fatty acids distinguished by a double bond three carbons from the methyl end. The main forms are eicosapentaenoic acid (EPA), docosahexaenoic acid (DHA), and plant‑derived alpha‑linolenic acid (ALA).

---

Where It Comes From

EPA and DHA are found in fatty fish (salmon, mackerel, sardines), fish oil supplements, and microalgae oils. ALA is present in flaxseed, chia seeds, walnuts, and canola oil.

---

Key Nutrients & Compounds

Supplemental omega‑3s provide high‑purity EPA and DHA ethyl esters or triglycerides, which integrate into cell membranes, modulate eicosanoid synthesis, and support neuronal function.

---

Health Benefits

Omega‑3s support heart health by lowering triglycerides, reducing blood pressure, and improving endothelial function. They promote brain development and cognitive performance, modulate inflammatory responses, and may aid joint comfort and mood regulation.

---

Recommended Dosage

General health: 250–500 mg combined EPA+DHA daily. Cardiovascular support: 1 g EPA+DHA daily. High‑dose therapeutic regimens (e.g., hypertriglyceridemia) may use 2–4 g per day under medical supervision.

---

How to Use It

Take omega‑3 supplements with meals, preferably containing fat, to enhance absorption. For algae‑based DHA, follow product‑specific guidelines. Maintain consistent daily intake for optimal tissue incorporation.

---

Who Should Use It?

Individuals seeking cardiovascular support, cognitive maintenance, or management of mild inflammation. Vegetarians and vegans may benefit from algae‑derived DHA/EPA supplements.

---

Possible Interactions or Cautions

High doses (>3 g/day) may increase bleeding risk; caution in individuals on anticoagulant or antiplatelet therapy. Fish oil supplements can cause mild gastrointestinal upset or fishy aftertaste.

---

Final Thoughts

Omega‑3 fatty acids are foundational for metabolic, cardiovascular, and neurological health. Ensuring adequate EPA and DHA intake through diet or supplements supports long‑term wellness.
