| Standard Dose | 500-1000 mg/day of seed extract (standardized to >8% polyphenols) or 10-15 seeds daily (traditional Ayurvedic dosing, escalated from 1 seed/day) | 800-2400 mg/day divided into 2-3 doses |
| 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. | Morning and early afternoon; avoid evening dosing due to mild stimulatory effect. Can be taken with or without food (water-soluble). |
| Cycle Duration | Traditionally used in 30-60 day courses. No established cycling protocol from clinical data. | Cycles of 8-12 weeks on, 4 weeks off |

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.

Modulates cholinergic neurotransmission by preventing scopolamine-induced decreases of acetylcholine in the hippocampus and cortex. Enhances D-aspartate release and modulates AMPA receptor activity. Demonstrates mild stimulatory properties without affecting dopaminergic or serotonergic systems, making it a 'cleaner' cognitive enhancer among racetams.
