OMEGA-3
BIOMARKER TEST
Rugby players absorb sub-concussive impacts across every session. DHA - the primary Omega-3 fatty acid in brain tissue - is the structural material your brain uses to recover from those hits.
The average athlete's Omega-3 Index sits around 4–4.5%. The 8% threshold, established primarily in cardiovascular research and increasingly applied to neurological health, is met by fewer than 1% of athletes tested. Most collision sport athletes have never had their levels measured (Heileson et al. (2025)).
01
Brain Protection
DHA constitutes a significant portion of brain cell membrane structure. Adequate Omega-3 status supports the neurological resilience required for collision sport athletes.
02
Recovery Capacity
Anti-inflammatory pathways are directly linked to EPA and DHA status. Low index = blunted recovery from both training load and contact events.
03
measurable progress
Omega-3 Index is a quantifiable biomarker that measures the omega-3 in your red blood cell membrane & indicates your long term omega-3 status. This is a level of precision nutrition you cannot achieve with generic blood tests as blood plasma only reflect the levels on the day of testing.

WORK WITH ELIZA
-
Fewer than 1% of collision sport athletes meet the Omega-3 threshold associated with neurological health and recovery. Most have never been tested. This home finger-prick blood test gives you your actual Omega-3 Index — the precision nutrition you cannot achieve with generic reference ranges used in blood tests.
What you get:
Your current Omega-3 Index level (blood tests can’t give us this level of detail)
Full fatty acid profile report including markers of inflammation
Omega-3 dietary analysis
Individual prescription of food and/or supplements to move your omega-3 index to optimum
Information explaining what your result means for your brain health, recovery capacity, and contact load tolerance
Option to also include Vit D testing
Precision nutrition, tailored to you & your life.
-
For anyone interested in optimising their nutrition for thriving. In 45 minutes, you receive a complete audit of your current nutrition approach and a clear plan to address where the gaps are costing your mental or physical performance. The same assessment framework used with elite athletes, applied to you.
