Why These Seven Ingredients Together?

Our formulation rationale — how we believe these compounds may complement each other, based on their individual mechanisms.*

Metabolic Energy Support

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.*

Cholinergic Support

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.*

Neurotransmitter 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.*

Stress Response Support

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.*
