TimingEarly morning on an empty stomach for faster hepatic conversion. Onset delayed 60-90 minutes. Avoid afternoon/evening dosing due to long effective duration.Morning, with or without food. Traditional practice involves gradual dose escalation starting from 1 seed daily, increasing by 1 seed per day up to 10-15.

Adrafinil

Nootropics

Mechanism

Inactive prodrug that is hepatically metabolized to modafinil (via hepatic amidase enzymes) and its inactive acid metabolite modafinilic acid. The active metabolite modafinil then exerts its effects as a DAT inhibitor with downstream orexinergic, histaminergic, and noradrenergic activation. Conversion is incomplete — approximately 33-50% of adrafinil is converted to modafinil, with the remainder forming inactive metabolites. The hepatic first-pass metabolism means onset is delayed (60-90 minutes vs. 30-60 minutes for modafinil).

Standard Dosing

300-600 mg once daily (for educational context — unregulated prodrug of a prescription medication)

Timing

Early morning on an empty stomach for faster hepatic conversion. Onset delayed 60-90 minutes. Avoid afternoon/evening dosing due to long effective duration.

Cycle Duration

Short-term or intermittent use strongly preferred. Avoid continuous daily use exceeding 3 months without liver function monitoring.

Side Effects

  • All modafinil side effects apply
  • Elevated liver enzymes (ALT/AST)
  • Potential hepatotoxicity with chronic use
  • Skin reactions
  • GI distress (more common than with modafinil due to hepatic metabolism)

Contraindications

  • Hepatic impairment of any severity
  • Concurrent hepatotoxic medication
  • All contraindications for modafinil apply (cardiac conditions, anxiety disorders, pregnancy)
  • History of liver disease or elevated liver enzymes

Mechanism

Seed oil contains sesquiterpenes, alkaloids (celastrine, paniculatin), and polyunsaturated fatty acids that demonstrate dose-dependent cholinergic activity by inhibiting acetylcholinesterase (AChE) and increasing acetylcholine levels in hippocampal and cortical regions. Provides neuroprotection against oxidative stress through elevation of glutathione (GSH), catalase (CAT), and superoxide dismutase (SOD). Seed extracts attenuate hydrogen peroxide- and glutamate-induced excitotoxic injury in neuronal cells, and exhibit anti-inflammatory and anxiolytic properties.

Standard Dosing

500-1000 mg/day of seed extract (standardized to >8% polyphenols) or 10-15 seeds daily (traditional Ayurvedic dosing, escalated from 1 seed/day)

Timing

Morning, with or without food. Traditional practice involves gradual dose escalation starting from 1 seed daily, increasing by 1 seed per day up to 10-15.

Cycle Duration

Traditionally used in 30-60 day courses. No established cycling protocol from clinical data.

Side Effects

  • GI distress
  • Nausea (especially at higher doses)
  • Diarrhea
  • Sedation at high doses

Contraindications

  • Pregnancy and lactation (insufficient safety data)
  • Known allergy to Celastraceae family plants
