Overview

Piracetam is a compound that gained attention in the mid-20th century, often described as a nootropic. It is a derivative of GABA (gamma-aminobutyric acid), although its mechanism of action does not primarily involve GABA receptors. First synthesized in the 1960s, it has been studied for its potential effects on cognitive functions, particularly in areas like memory and learning. It is available under various brand names, with Nootropil being one of the most recognized globally. While extensively studied, its classification and regulatory status vary significantly across different countries, being available as a prescription drug in some, and an over-the-counter supplement in others, or not approved for medical use in others (Examine.com, DrugBank). Structurally, Piracetam is a cyclic derivative of GABA, with the chemical formula C6H10N2O2. Its half-life in the body is approximately 5 hours, meaning it takes about 5 hours for half of the administered dose to be eliminated. It is generally lipophilic, allowing it to cross the blood-brain barrier. Piracetam's primary route of excretion is via the kidneys, largely unchanged (DrugBank). It can be taken with or without food, and has been studied for morning administration. It is not an injectable compound.

Known interactions

  • Category rule: glp1 × supplement
    Note

    GLP-1 medications slow stomach emptying, changing how/when oral supplements absorb; rapid weight loss raises the importance of protein and micronutrients.

    Time oral supplements when nausea is lowest; prioritize protein and micronutrients; discuss with your provider.

  • Category rule: supplement × medication
    Note

    Some supplements change how the body processes medications (absorption, liver enzymes, or additive effects).

    Specific pairs are checked against a licensed drug database and shown with their own severity. Always confirm with your provider or pharmacist.

  • Compound-pair rule
    Synergy

    Racetams increase acetylcholine turnover; adding a choline source can prevent headaches from choline depletion.

    Consider stacking 300–600 mg alpha-GPC with racetam doses.
