Why These Seven Ingredients Together?
Our formulation rationale — how we believe these compounds may complement each other, based on their individual mechanisms.*
Benfotiamine + Alpha-Lipoic Acid
Benfotiamine supports cellular glucose metabolism while Alpha-Lipoic Acid supports mitochondrial energy production and antioxidant activity. Together they are intended to support the cellular energy processes that may underlie brain fog.*
Huperzine A + Black Maca + Phosphatidylserine
Huperzine A and Black Maca have both been studied for effects on acetylcholinesterase, while Phosphatidylserine supports neuronal membrane integrity — intended together for multi-targeted cholinergic support.*
L-Glutamic Acid + Huperzine A + 5-HTP
L-Glutamic Acid is an amino acid involved in neurotransmitter synthesis. Combined with serotonin precursor support from 5-HTP, this axis is intended to support neurotransmitter balance.*
Phosphatidylserine + Black Maca
Phosphatidylserine has been studied for effects on the cortisol stress response, while Black Maca is a traditional adaptogen. Together they are intended to support cognitive resilience under stress.*
