Alpha-GPC

Nootropics

Mechanism

Highly bioavailable choline source that crosses the blood-brain barrier efficiently via passive diffusion. Serves as a direct precursor for acetylcholine synthesis and phosphatidylcholine, a major structural component of neuronal membranes. Also stimulates growth hormone release via cholinergic activation of GHRH-releasing neurons in the hypothalamus. Contains ~40% choline by weight.

Standard Dosing

300-600 mg/day

Timing

Morning or pre-workout. Can be taken with or without food. Split into 1-2 doses.

Cycle Duration

Ongoing; no cycling required for standard doses

Side Effects

  • GI distress
  • Headache
  • Dizziness
  • Fishy body odor at high doses
  • Potential TMAO elevation with chronic high-dose use

Contraindications

  • Active peptic ulcer disease
  • TMAO concerns — emerging research links high choline intake to elevated TMAO and cardiovascular risk

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
