Omega 3 Unfiltered: The clear guide to stop wasting money on empty capsules

1. Are fats bad? Not all. What Omegas are

In summer, “fat” sounds like beach-fryer food… but your body needs certain fats to thrive. Don’t demonize them all. Among them, essential fatty acids that your body CANNOT make and must get from food.

Omega-3 → derived from ALA (alpha-linolenic acid)
Omega-6 → derived from LA (linoleic acid)

From ALA you can make EPA and DHA (under 1%). From LA you can make AA (arachidonic acid). These are the “bricks” of cell membranes. Excess trans/saturated fats = rigid walls; polyunsaturated like Omega-3 = flexible walls. Poor cell-to-cell communication equals dysfunction.

2. Arachidonic acid (AA) and health

AA is the most abundant omega-6 in Western diets. Found in eggs, cheese, cured meats, meat and fish. Necessary, but in excess drives chronic inflammation. Sugar + refined vegetable oils = more AA. Balancing AA vs EPA/DHA is key.

3. Types of Omega-3 and sources

Land: flax, chia, walnuts. Very low conversion to EPA/DHA.
Sea: oily fish, krill and microalgae. Fish don’t make it; they get it from phytoplankton. Choose sardines, anchovies, mackerel, bonito… Avoid large fish like tuna (heavy metals).

4. What about algae?

Some microalgae contain EPA/DHA, though often at low doses. Vegan microalgae supplements are usually limited to ~250 mg DHA, whereas fish oils can go up to 3000 mg/day. They also tend to provide more DHA than EPA, limiting anti-inflammatory effect.

5. Benefits by type

DHA: brain & vision (memory, focus, dry eye, neurodegeneration prevention).
EPA: natural anti-inflammatory (joints, skin, mood, cardiovascular health).

6. Which to take

Prefer marine (EPA+DHA). Vegans: microalgae, with dosing limits.
Form: triglycerides and phospholipids are best absorbed. Avoid ethyl ester (EE).
Capsules: animal gelatin preferred; carrageenan is a vegan option but may irritate.
Seals: IFOS (purity), FOS (sustainability).
Dose: <1 g = nutritional effect, ≥1 g = physiological effect.

7. Storage & antioxidants

Omega-3 oxidizes easily. Refrigerate after opening. It’s a good sign to see antioxidants like vitamin E or rosemary extract. Krill naturally contains astaxanthin.

8. Conclusion

Choosing Omega-3 isn’t just buying capsules: check dose, origin and purity. In average fish oil, only ~30% is actual Omega-3. Cheap ends up expensive—invest in quality and keep the habit: eat oily fish at least 3 times a week.
