Measurable Bioavailability
A dose-dependent increase in plasma Trp:LNAA ratio — the gold-standard marker for brain tryptophan availability. A casein control beverage decreased the ratio by 9% in the same study.
NA2R® is a clinically proven tryptophan-rich egg protein hydrolysate engineered to raise brain serotonin — naturally, measurably, and at doses that work in your formulation.
Serotonin synthesis starts with tryptophan. NA2R® is engineered with a uniquely high Trp:LNAA ratio — so more tryptophan crosses the blood-brain barrier, and more serotonin gets made.
NA2R® is an enzymatic hydrolysate of hen egg white protein. Its amino acid composition is precision-engineered to maximise the tryptophan-to-large neutral amino acid (Trp:LNAA) ratio — limiting competition at the transport site that matters most.
Tryptophan competes with other LNAAs at the LAT1 transporter on the blood-brain barrier. NA2R®'s low-LNAA matrix clears the competition — measurably raising the plasma Trp:LNAA ratio by up to 48% within 90 minutes of consumption.
More brain tryptophan triggers the tryptophan → 5-HTP → serotonin pathway. Clinical outcomes include balanced mood, reduced fatigue, sharper focus, faster reaction time, and improved sleep quality — at regulatory-approved doses.

NA2R® is backed by 7 peer-reviewed studies published in leading scientific journals. These are the headline findings.
A dose-dependent increase in plasma Trp:LNAA ratio — the gold-standard marker for brain tryptophan availability. A casein control beverage decreased the ratio by 9% in the same study.
Randomised double-blind controlled trial: NA2R® produced a significant shift toward positive emotional processing and prevented the wellbeing decline observed in the placebo group.
19-day parallel RCT: chronic NA2R® treatment improved emotional bias, increased mental energy levels, accelerated reaction times, and improved sustained attention throughout the treatment period.
