Scientific Dual-Coverage Profile

Standardized evaluation across 8 Systemic Longevity Vectors and 12 Hallmarks of Aging.

Heart & Cardiovascular

Neutral Pathway
0/ 100

No direct primary biochemical modulation of heart health; pathway is neutral for Ceremonial Matcha Green Tea (EGCG & L-Theanine).

Brain Longevity & Cognition

Foundational Target (65-100)
88/ 100

Synergistic combination of caffeine with high-dose L-theanine promotes relaxed cognitive alertness (alpha brainwave state) while EGCG crosses into the CNS to scavenge peroxynitrite radicals and inhibit acetylcholinesterase.
