Theacrine
Theacrine is a purine alkaloid structurally similar to caffeine but with a longer half-life (~26 hours vs ~6 hours) and less habituation. Studies show subjective improvements in energy and mood without affecting hemodynamics. Often combined with caffeine for enhanced cognitive performance. Found naturally in Kucha tea. Does NOT cause tolerance over 8 weeks unlike caffeine.

Cistanche is a parasitic desert plant used in Traditional Chinese Medicine for vitality, sexual function, and cognition. Contains phenylethanoid glycosides including echinacoside and acteoside. RCT (n=48, 8 weeks): 5g/day Cistanche deserticola significantly increased testosterone, reduced cortisol, improved 1RM squat and muscle endurance (p<0.05). Reduced CRP and CK markers (p<0.01). RCT for chronic fatigue (n=190, 60 days): Cistanche+Ginkgo improved fatigue symptoms. Clinical study (48 weeks, 300mg/day): Improved cognitive function in moderate Alzheimer's patients. Preclinical systematic review (20 studies, n=1696): Strong neuroprotective effects.
Vitamin C

Vitamin C, or ascorbic acid, is an essential vitamin and a very popular supplement due to its antioxidant properties, safety profile, and low price. Many people supplement with vitamin C because it is believed to reduce symptoms of the common cold.
Urolithin A
1 shared condition · 7 outcomes
Urolithin A is a gut-microbiome-derived metabolite from pomegranate and berries that activates mitophagy (removal of damaged mitochondria). RCTs show ~12% improvement in muscle strength and significant endurance gains in older adults. Also reduces inflammation (CRP) and improves mitochondrial efficiency. One of the more promising healthy aging supplements with solid human evidence. Only ~40% of people produce UA naturally - supplements bypass this variability.
Tryptophan
1 shared condition · 6 outcomes
L-tryptophan is an essential amino acid precursor to serotonin. 40 controlled studies show doses ≥1g reduce sleep latency. Effective for mild-moderate depression but not severe. Used successfully for seasonal affective disorder. Do not combine with SSRIs/MAOIs (serotonin syndrome risk). 1989 contamination incident (EMS outbreak) was traced to single manufacturer - supplement itself is safe.

Spermidine is a polyamine that induces autophagy by inhibiting EP300 acetyltransferase. Epidemiological studies link higher dietary intake to 24% reduced mortality and lower cardiovascular/cognitive disease risk. RCTs show cognitive benefits in elderly. Major ongoing trial (POLYCAD) testing cardiovascular effects. One of the more promising longevity compounds with actual human data. Found in wheat germ, aged cheese, mushrooms, soybeans. Levels decline with age.
