Metrics for Life

The BrainSpan® Assessment is a revolutionary, FDA cleared test that will help you optimize your brain function and increase your overall resilience. 


This is accomplished by measuring, tracking, and improving specific fatty acid and cognitive function metrics. These actionable metrics indicate the health of cells within the brain and throughout the body.

An Integrated Two-Part Test Kit

Cell Structure

  • A brief stick of a finger and then blot a few drops of blood on specially treated filter paper.

  • Specific fatty acids such as the Omega-3 Index, the Omega-6 to Omega-3 ratio and 25 others provide vital information on dietary health.

  • Specific fatty acids play a major role in cell membrane health...and thus the function and resilience of specific organs such as the brain.

Cell Function

  • A 15-20 minute web-based, well-validated set of five cognitive challenges done on a computer or touchscreen device.

  • The test measures 4 main domains of brain function: memory, processing speed, flexibility, attention, and overall executive function.

  • The test requires no special software and only an internet connection.

Simple, Measurable Guidance on How to Improve

Take charge of the factors that can greatly influence the health of your brain and body.

  • Use the simple summary page at the back of the report to track progress and view recommendations.

  • As you make changes and stay committed to them, your scores will improve when performing the recommended re-tests in 90 and 180 days.

Validated and Trusted

In Keep Sharp (Gupta, 2021), New York Times Best Selling author, Dr. Sanjay Gupta,  explains the direct benefit of BrainSpan through an interview with Founder, Dr. Daniel Johnston. Building a better brain can transform the quality of our life. But it all starts with the basics of nourishing our cells with the right types and quantities of fatty acids.

Giving You Confidence:

Tracking Test and Retest Progress

The average Omega-3 Index in the US is about 4%. The optimal ratio based on many well published studies is 9%.

The average ratio of pro-inflammatory nutrients to anti-inflammatory is 25:1. The ratio should be 5:1 or better.

Excess carbohydrates are turned into palmitic acid, disrupting leptin signaling and increasing cell damage.

Your ability to remember and recall information is vital to aging gracefully.

Staying focused on tasks with a high attention to detail is important to productivity.

Quickly understanding and accurately responding to information impacts our entire quality of life.

Practice Integration

Clinically Specific Applications

  • A Stronger Gut-Brain Axis

    Proper fatty acid levels enhance levels of good bacteria in the gut. This improves the health of GI tract and immune system.

  • Improve Focus & Attention

    Most children today are deficient in optimal levels of Omega-3 EPA/DHA. These are critical for focus and development.

  • Improve Lean Body Mass

    Excess dietary carbohydrates and poor Omega-3 intake are both associated with poor weight management and diabetes later in life.

  • Healthier Pregnancies

    Several studies demonstrate improved perinatal outcomes, reduced delivery complications and post-partum depression.

  • Decrease Inflammation

    Inflammation plays a major role in nearly all chronic diseases as well as chronic pain from a variety of conditions.

  • Reduce Cognitive Decline

    Fatty acids play a critical role in both the very young and the very old. Neurodevelopment and resilience to aging depend on fatty acids.

A Workflow to Fit Any Practice

Step 1:

Finger Stick Blood Spot

Collect 2-3 drops of blood on a special card. Then use the postage paid return envelope to mail your sample to our CLIA certified lab.

Step 2:

Take the Cognitive Test

After you register your kit, you will receive access to take a 15 minute cognitive function test. There is no software to download.

Step 3:

View Your Report & Plan

Within 5 days of receiving your sample, your personalized report and recommendations are ready to view, print, or download.

 “BrainSpan® is a powerful health and wellness tool that was conceived during a deployment to combat while serving in the US Army.  The key was not just prevention, but optimization and resilience. No one should live their life today without knowing their BrainSpan numbers."
