Triacetylruridine

Also known as: TAU, triacetyluridine, uridine triacetate

C
Evidence

Triacetylruridine is a prodrug form of uridine designed for enhanced bioavailability and membrane permeability to support cellular energy metabolism and cognitive function. Preliminary evidence suggests potential benefits for cognitive performance and neuroprotection, though human clinical data remains limited.

Primary uses

  • Cognitive enhancement
  • Mental energy and focus
  • Neurological support
  • Mitochondrial function

How it works

  • Acetylated uridine prodrug improving blood-brain barrier penetration
  • Increases intracellular uridine availability for nucleotide synthesis
  • Supports ATP and phospholipid production in neural tissue
  • May enhance membrane fluidity and synaptic function

Dosage

Typical range
250-1,000 mg daily
Timing
Morning or early afternoon for cognitive support
With food
May be taken with or without food; food may slightly enhance absorption
Duration
Often used in 4-12 week cycles; long-term safety profile not extensively studied
Special populations
Pregnancy and lactation: safety not established; use with caution in those with uridine metabolism disorders

Forms

  • Capsule· 70/100

Safety

Common side effects

  • Generally well-tolerated at typical doses
  • Headache (rare)
  • Gastrointestinal upset (uncommon)

Contraindications

  • History of gout or elevated uric acid (uridine metabolizes to uric acid)
  • Severe liver or kidney impairment
  • Concurrent use with high-dose cytotoxic chemotherapy

Evidence notes

Limited human clinical trials; mostly in vitro and animal model data supporting neurological mechanisms. Some observational use in nootropic communities but lacks robust RCT evidence for cognitive endpoints in healthy humans.

Grade C: Mostly observational or small trials; mechanism is plausible but unproven at scale.
