Omega-3 fatty acids are among the most studied nutrients in the world — and for good reason. They support heart function, brain performance, inflammation control, immune resilience, and emotional wellbeing. Despite this, most people aren’t getting enough.
🧠 Why Omega-3 Deficiency Matters
EPA and DHA are omega-3 fats found in marine sources like fatty fish and algae. A deficiency can lead to:
- Chronic inflammation and pain
- Increased cardiovascular risk
- Brain fog and poor cognitive function
- Low mood or emotional instability
- Fatigue, dry skin, or joint stiffness
These signs are often misattributed to stress or aging, allowing deficiency to go unnoticed for years.
🍟 Common Causes of Low Omega-3
- Low intake of oily fish (salmon, sardines, anchovies)
- Vegetarian or vegan diets without algae-derived omega-3
- High omega-6 intake from processed foods and seed oils
- Poor fat absorption or chronic gut inflammation
🧪 How to Test for Omega-3 Deficiency
The Omega-3 Index is the gold standard blood test to measure EPA and DHA levels in red blood cells. It reflects long-term intake and correlates with cardiovascular and cognitive health.
At VitaminTestKits.com, choose from:
- Omega-3 Index Basic Test – a simple measure of EPA + DHA % in blood
- Omega-3 Plus Ratios Test – includes your omega-6:3 and AA:EPA ratios
- Omega-3 Complete Test – includes total omega-3, trans fats, and 24 individual fatty acids
All tests use an at-home dried blood spot (DBS) kit, are easy to use, and include a full lab report with actionable insights.
📈 What’s a Good Omega-3 Index?
An Omega-3 Index of 8% or higher is considered optimal for heart and brain health. Most people in Western countries have levels between 3% and 5% — well below ideal.
🐟 How to Improve Your Omega-3 Levels
- Eat oily fish 2–3 times per week
- Take a quality fish oil or algae-based omega-3 supplement
- Reduce omega-6-rich seed oils like sunflower or soybean oil
- Track your results with follow-up testing every 3–6 months
Tip: DHA, the omega-3 that accumulates in the brain, takes time to build up — consistency matters more than dose.
🧬 Why Test, Not Guess?
Even if you supplement, you might not reach your target Omega-3 Index. Factors like dose, absorption, product quality, and dietary habits affect how your body responds. Testing gives you the data to personalise your plan and stay on track.

🔎 FAQs About Omega-3 Deficiency
What’s the difference between EPA and DHA?
EPA (eicosapentaenoic acid) supports inflammation regulation and cardiovascular health. DHA (docosahexaenoic acid) is vital for brain structure and cognitive function. Both are measured in the Omega-3 Index.
How often should I test my Omega-3 levels?
We recommend testing every 3–6 months if you are adjusting your diet or starting supplements. Once stable, yearly testing is sufficient.
Can I test omega-3 levels at home?
Yes. All Omega-3 tests from VitaminTestKits.com use dried blood spot (DBS) technology, which allows easy at-home collection with a finger prick.
What if my Omega-3 Index is too low?
Increase fatty fish intake, consider a daily omega-3 supplement (1,000–2,000mg EPA+DHA), and reduce processed seed oils. Retest after 3 months to check your progress.
