If you're not getting this blood test, you're doing yourself a huge disservice. Here's everything you need to know.
When doctors draw blood and run a standard panel, they're usually checking things like blood cell count, blood sugar, kidney function, liver enzymes, and cholesterol. Hopefully, you're getting a comprehensive hormone panel, too. These things are important, and your doctor will quickly prescribe drugs to "fix" any issues that come up.
What doesn't your doctor typically check? Magnesium, zinc, and vitamin D. These deficiencies are widespread and strongly impact your overall health. But Big Pharma doesn't make money from nutritional supplements, so screw you, buddy.
By now, you're probably at least requesting a vitamin D test or paying for one out of pocket. Good for you. But there's another, newer test you should be getting, too.
The Omega-3 Index Test
This test has only been widely available for a few years, but it's catching on. The concept was proposed by Dr. William Harris and Dr. Clemens von Schacky in a landmark paper back in 2004. They argued that measuring EPA and DHA in red blood cell membranes was a better predictor of cardiovascular risk than dietary intake or plasma levels.
They were right, and today you can request the test from your doctor, order an at-home finger-prick test, or use one of those walk-in labs like Quest or LabCorp. The cost? Typically, $60 to $120. Insurance doesn't cover it, but it's worth getting.
What the Test Tells You
The Omega-3 Index test measures the percentage of EPA and DHA (the key long-chain omega-3 fatty acids) in your red blood cell membranes. When you get the results back, here's what to look for:
- Less than 4% – High-risk zone
- 4-8% – Intermediate zone
- 8-12% – Optimal zone
The typical U.S. average is 4-5%, right at the danger zone. But what do these numbers mean?
From High Risk to Optimal
First, let's look at the problems associated with a low score, around 4% and below.
Brain and Mental Health Risks:
- Depression and anxiety
- Poor memory
- Brain fog
- Mood instability (less emotional resilience, more stress sensitivity)
- Cognitive decline (higher dementia and Alzheimer's risk)
- ADHD-like symptoms
Physical and Neurological Risks:
- Inflammation, including neuroinflammation
- Visual fatigue and eye-brain signaling issues
- Higher risk of stroke-related brain damage
- Weaker synaptic plasticity (limits learning)
- Sleep problems
Now let's flip it. What benefits do you get when you hit the 12% "neuroprotective elite" level?
Mental and Cognitive Benefits:
- Crystal-clear focus (faster processing, improved attention span)
- Sharper memory
- Mood stability
- Resilience to stress
- Lower dementia risk
- Better sleep
Physical and Neurological Benefits:
- Optimal neuronal membrane fluidity
- High synaptic plasticity
- Anti-neuroinflammatory state (less brain inflammation)
- Protection from stroke and brain injury
- Eye support (DHA-rich membranes in the retina enhance vision and eye-brain coordination)
- Slower brain aging
In short, 12% isn't just good. It's a brain-optimized, longevity-favoring state.
How to Hit 12%
Populations with high fatty fish intake (like Japan) often score 9-12% on the Omega-3 Index. But remember, the average American is hovering right at the danger zone, and even daily fish eaters have a hard time getting close to 12% without the right supplementation.
DHA is the primary omega-3 for brain, heart, and eye health, and most fish oil supplements contain far more EPA. Even after months of taking standard fish oil, you'd be lucky to get anywhere near 12%.
What you need is a high-dose, DHA-rich formula using Labrasol (caprylocaproyl polyoxyl-8 glyceride). This pharmaceutical delivery agent essentially makes fish oil 3-4 times more effective.
That's why we included it in our fish oil, Flameout (Buy at Amazon), which contains five times more DHA than EPA. Just take three softgels per day.
Note: Labrasol is also used in D Fix Vitamin D (Buy at Amazon) and the T-booster Omega-Man (Buy at Amazon).
