Phosphatidylserine
Phosphatidylserine (PS) is an amino acid derivative that is fat soluble and found in high amounts in the brain, where it contributes to cognitive functioning. PS has been studied the most for cognition in adults over 50, for people with high chronic stress, and for exercise performance, but further research is needed to confirm any benefit.

Ginkgo biloba is the most commonly ingested herb for brain health. While it may boost cognition in older populations, this effect is not very reliable or generalizable.
Fish Oil
9 shared conditions · 448 outcomes
Fish oil is a mix of mostly EPA and DHA derived from fatty fish. It reduces triglycerides, but does not seem to affect the rate of cardiovascular events. It appears to reduce the symptoms of depression and improve some painful, inflammatory conditions.
Bacopa Monnieri
9 shared conditions · 53 outcomes
Bacopa monnieri is an Ayurvedic nootropic herb traditionally used for memory and cognitive enhancement ('Medhya Rasayana'). C-grade evidence for anxiety improvement, anhedonia (in depression), and alertness. D-grade for attention and Alzheimer's symptoms (no effect). Memory benefits are more consistent but require 8-12 weeks of consistent use. Works primarily via bacosides affecting cholinergic and serotonergic systems. One of the better-studied herbal nootropics but effects are modest and slow-developing.
Vitamin E
8 shared conditions · 274 outcomes
Vitamin E is a fat-soluble antioxidant that protects cells from oxidative damage and is found in several common foods. Supplementing with extra vitamin E does not have broad health benefits, except in people with vitamin E deficiency, and long-term high-dose supplementation may cause harm.
Panax Ginseng (Korean Ginseng)

Piracetam is the parent compound of the racetam class of nootropic supplements. When supplemented, it provides a mild boost to brain function.
L-Tyrosine
7 shared conditions · 182 outcomes
L-Tyrosine is an amino acid that is used as a precursor for the synthesis of the catecholamines dopamine (DA) and norepinephrine (NE). DA and NE are depleted under stressful conditions, which can compromise cognitive function. L-Tyrosine supplementation may help alleviate acute stress-induced cognitive decline by restoring catecholamine levels in the brain.
