Elad Gil's pragmatic longevity stack and what he's watching next

Executive overview

Most longevity content is noise. The fundamentals — sleep, exercise, diet — account for the majority of what actually matters. A short list of supplements may help at the margins, but the more interesting territory is experimental: rapamycin pulsing, ketone esters, bioelectric medicine, and ibogaine as a neurological "reboot."

The real edge in longevity right now is knowing what to wait for, not what to take today.

The short list that actually holds up

• Creatine and vitamin D are the two supplements Elad names without hesitation
• Sleep, exercise, and diet remain the dominant variables — most other interventions collapse back into these
• Methylation issues or medications (e.g., omeprazole) can affect magnesium absorption — worth monitoring
• Urolithin A has mounting data; worth attention for mitochondrial health
• Ketone esters and salts may be useful for cerebral vasculature, particularly for those with family history of Alzheimer's or Parkinson's

Fasting and mitophagy

• Intermittent fasting and periodic three-to-seven day fasts (or fast-mimicking diet) can foster autophagy and mitophagy
• Not a constant practice — occasional, with intention
• Based on input from Dr. Dominic D'Agostino

Rapamycin — interesting with heavy caveats

• Rapamycin is a genuine area of interest, but it is an immunosuppressant
• Misuse without medical oversight carries real risk
• One hypothesis being explored: combining Norwegian 4x4 interval training with rapamycin pulsing and measuring hippocampal volume changes

Ibogaine as neurological reboot

• The "reboot" concept — like rebooting a computer — has a real pharmacological candidate in ibogaine
• Flood dosing has allowed opiate addicts to emerge without physical withdrawal symptoms
• Pre/post MRI studies (Nolan Williams's lab) showed apparent reversal of brain age markers in veterans with traumatic brain injury
• Mechanism may involve glial-derived neurotrophic factor (GDNF)
• Dangerous: can cause fatal cardiac events; magnesium co-administration reduces risk; requires medical supervision

Bioelectric medicine and brain stimulation

• Non-invasive brain stimulation is viewed as one of the next major frontiers
• Relevant for psychiatric conditions and potentially performance enhancement
• GLP-1 agonists offer a preview of system-wide behavioral shifts from a single intervention
• Implants may follow non-invasive approaches over time

What Elad is waiting for

• "Real drugs" — still in development — are the bigger opportunity
• Eye drops to address lens-muscle weakening (a neurosensory aging target)
• Obesetrapib — not yet ready, but worth tracking
• Peptides are largely cosmetic in effect (BPC-157, melatonin analogues)
• General anesthesia warrants more caution than commonly assumed — mechanisms poorly understood; some patients emerge with lasting memory or personality changes

Heuristic for filtering

• "No biological free lunch" — a simple but useful filter for avoiding pitfalls
• High experimentation in earlier years; now more conservative
• Waiting for cleaner signal before adding interventions; ideally one at a time
