Omega-3
Omega-3 Fatty Acids (EPA/DHA)
Essential fatty acids critical for brain health, cardiovascular function, and inflammation regulation. One of the most studied and recommended supplements globally.
How Omega-3 Works
EPA (eicosapentaenoic acid) and DHA (docosahexaenoic acid) are incorporated into cell membrane phospholipids, improving membrane fluidity and receptor function. EPA is the primary anti-inflammatory omega-3, serving as a precursor to resolvins and protectins — specialized pro-resolving mediators that actively terminate inflammatory responses. DHA constitutes 30-40% of brain cortical phospholipids, supporting neuronal membrane integrity, synaptic plasticity, and neuroprotection. Both compete with pro-inflammatory omega-6 (arachidonic acid) for cyclooxygenase and lipoxygenase enzymes.

Side Effects & Safety
Interactions & Contraindications
Drug Interactions
- •Blood thinners (warfarin, aspirin, clopidogrel) — omega-3 has mild antiplatelet effect, monitor INR
- •Blood pressure medications — omega-3 may mildly lower blood pressure (additive effect)
- •Orlistat (weight loss drug) — reduces omega-3 absorption
Supplement Interactions
- •Synergistic with astaxanthin for cardiovascular and anti-inflammatory benefits
- •Vitamin E — protects omega-3 from oxidation (many quality fish oils include it)
- •Curcumin — combined anti-inflammatory effects via different pathways
Food & Timing
- •Best absorbed with a fat-containing meal
- •Wild-caught fatty fish (salmon, mackerel, sardines) provide EPA+DHA directly
- •Plant sources (flaxseed, chia) provide ALA with very poor conversion to EPA/DHA (<5%)
Who Should Avoid
- •Fish or shellfish allergy (unless using algae-derived omega-3)
- •Scheduled surgery — discontinue high-dose omega-3 5-7 days before due to antiplatelet effect
- •Active bleeding disorders

Frequently Asked Questions
For general health, 1-2g of combined EPA+DHA daily. For targeted anti-inflammatory effects, 2-4g of EPA+DHA (clinical doses used in REDUCE-IT trial for cardiovascular benefit). Focus on the EPA+DHA content on the label, not total fish oil. A capsule containing 1000mg fish oil may only deliver 300mg EPA+DHA.
Triglyceride-form fish oil has better absorption than ethyl-ester form. Look for brands that specify 'TG form' or 'rTG form' (re-esterified triglyceride). High-quality brands available in the UAE include Nordic Naturals, Carlson, and WHC. Algae-based omega-3 (from microalgae) is the best vegan option and avoids ocean contaminant concerns.
If you consume 2-3 servings of fatty fish (salmon, mackerel, sardines) per week, you may be getting adequate omega-3. However, most UAE residents do not eat enough fatty fish. Additionally, farm-raised fish has significantly lower omega-3 content than wild-caught. An omega-3 index blood test (target 8-12%) can determine your actual status.
Reputable fish oil manufacturers use molecular distillation to remove heavy metals, PCBs, and dioxins. The final product typically contains negligible mercury. Look for third-party tested brands with IFOS (International Fish Oil Standards) certification. Small fish sources (sardines, anchovies) naturally accumulate less mercury than large predator fish.
