Gut barrier
The intestinal mucus layer shields the body from digestive enzymes and bacteria; animal studies show it thins with age and with food emulsifiers, and she considers its integrity essential to healthy aging (the autodigestion theory).
5 interventions act here
C15:0 (Pentadecanoic Acid)
Odd-chain saturated fat linked to better metabolic and heart health in observational studies; supplement trials show minimal effect.
Skeptical
Arginine
Semi-essential amino acid that fuels T cells and feeds spermidine; reduced amyloid-beta in Alzheimer's mice.
In my stack
L-Glutamine
Abundant amino acid fueling gut lining cells and mucus; she takes it to protect the gut barrier.
In my stack
Light at Night & Melatonin
Bright days and dark nights maximize melatonin, an antioxidant linked to lower mortality and Alzheimer's protection.

Microplastics Reduction
Cutting nanoplastic exposure, found in arterial plaque and brain tissue, and keeping the gut barrier strong.
