Scoring Methodology

How Vitaei evaluates and ranks longevity interventions based on scientific evidence.

Evidence Tier System

Every molecule in the Vitaei index is assigned one of three evidence tiers based on the quality and quantity of human research.

Tier I

Multiple Human RCTs

Multiple randomized controlled trials in humans demonstrating efficacy. Gold standard for safety and efficacy. Examples: Metformin, Vitamin D3, Omega-3.

Tier II

Human Trials (Early)

Early-stage human trials or observational studies showing promise. Requires further validation. Examples: NMN, Rapamycin, Spermidine.

Tier III

Mechanism / Animal Studies

Strong mechanistic evidence or animal studies, but limited human data. Promising but speculative. Examples: Fisetin, Urolithin A.

Hallmark Mapping

Each intervention is mapped to the 12 hallmarks of aging it addresses, based on peer-reviewed literature.

H01

Genomic instability

DNA damage and repair defects

H02

Telomere attrition

Chromosome end shortening

H03

Epigenetic alterations

DNA methylation changes

H04

Loss of proteostasis

Protein misfolding and aggregation

H05

Mitochondrial dysfunction

Energy production decline

H06

Cellular senescence

Growth arrest and inflammation

H07

Stem cell exhaustion

Regenerative capacity loss

H08

Altered intercellular communication

Signaling pathway disruption

H09

Nutrient sensing dysregulation

mTOR/AMPK imbalance

H10

Microbiome alterations

Dysbiosis and inflammation

H11

Disabled macroautophagy

Cellular cleanup failure

H12

Chronic inflammation

Inflammaging

Price Calculation

Prices are calculated as cost per active milligram per day, based on verified vendor pricing and recommended dosing.

Price/day = (Product cost / mg of active ingredient) × recommended daily dose
