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.
300-600 mg/day
Morning or pre-workout. Can be taken with or without food. Split into 1-2 doses.
Ongoing; no cycling required for standard doses
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.
