Triacetyluridine (TAU), also known as uridine triacetate, is a nucleoside and precursor for uridine, a component of RNA. Triacetyluridine is one of the most bioavailable forms of uridine with important neurological potentials.


Triacetyluridine (TAU) Benefits and Uses

Triacetyluridine (TAU) is a pyrimidine nucleoside, which is composed of the nucleotide uracil bound to a ribose sugar, and is a component of RNA (ribonucleic acid). RNA is the compound responsible for the translation of genes into proteins.

Triacetyluridine has benefits on cognitive functions such as learning and memory. Although there are many available forms of dietary Uridine, Triacetyluridine appears to be the most bioavailable type and most regarded for its neuroprotective properties. Research suggests that supplementing with Triacetyluridine boosts mood, mental energy and has an overall neuroprotective effect.


Triacetyluridine supplements are also known by a few different names, including:

  • Uridine Triacetate
  • TAU
  • PN401
  • Vistogard
  • Xuriden
  • Vistonuridine
  • Uridine, 2’,3’,5’-triacetate
  • Tri-O-acetyluridine
  • Triacetyl uridine

Scientific Consensus

Studies show that using Triacetyluridine (TAU) within the recommended serving size is generally safe with only mild potential adverse effects. Anecdotal evidence has found TAU may be the most effective when stacked with other supplements such as choline. TAU may cause side effects such as nausea, headaches and upset stomach.

There isn’t sufficient data regarding the safety of Triacetyluridine for pregnant or breastfeeding women, or if it can be used by children. Please consult with your doctor before trying this product.

Triacetyluridine (TAU)

Triacetyluridine is a naturally-occurring compound and precursor to the nucleoside Uridine (pictured to the left). Uridine plays an important role in cellular signaling, and supports both CDP-Choline and dopamine levels in the brain. For this reason, Triacetyluridine is becoming a sought after dietary supplement for its perceived effect in boosting cognitive function, memory and mood. - Promotes Healthy Memory and Cognition - Potent Neuroprotective Benefits - Supports a Positive Mood
