What this protocol is
Built for the person who gets home at 9:30pm and is supposed to sleep by 11:30.
The original version was built on Western sleep hygiene defaults: a 9-to-5 schedule, dinner at 7pm, supplements at 9pm, asleep by 10:30. That describes approximately zero Indian desk workers in Delhi, Mumbai, or Bengaluru.
This revision is calibrated to what actually happens: a commute ending at 9–10pm, dinner at 10:30, and a target sleep time of 11:30pm–midnight. Supplement timings, caffeine cutoffs, and the melatonin dosing window have all been recalculated around that reality.
What changed from the original version
The IST commute reality
Metro commute data from the Ministry of Housing and Urban Affairs (2023) puts the average one-way commute in Mumbai at 67 minutes, Delhi at 58 minutes, Bengaluru at 54 minutes. Workers leaving office at 8:30–9pm arrive home between 9:30 and 10pm.
Standard sleep hygiene recommends eating dinner at least 3 hours before bed. If a person wants to sleep at midnight, dinner should be at 9pm. They are walking in the door at 9:45pm. Dinner happens at 10:15–10:30. The 3-hour window is structurally unavailable — not because of poor choices, but because of geography and work culture.
A sleep protocol that ignores this isn't a sleep protocol for Indian desk workers. This revision starts from the 10pm arrival, not from a textbook ideal.
How a 10:30pm dinner affects your melatonin
Melatonin secretion from the pineal gland is suppressed by light and by food-entrainable circadian signals. A meal at 10:30pm — particularly one containing carbohydrates — activates gut-brain pathways that delay the evening melatonin rise by approximately 45–90 minutes relative to a 7pm dinner.1
This is not a reason to avoid eating late — it is a reason to account for it when timing supplemental melatonin. If your endogenous melatonin onset is pushed to 11:30pm by the late meal, taking exogenous melatonin at 9pm does not reinforce your biology — it gets ahead of it, which can phase-advance your rhythm and make tomorrow's 8am meeting harder.
The revised timing window: take melatonin at 10:30–10:45pm for a target sleep time of midnight. This places the dose approximately 75 minutes before target sleep onset — the window most chronobiological research supports for entrainment rather than sedation.2
Revised caffeine cutoff table
Caffeine's half-life in healthy adults averages 5–6 hours, with a wide individual range (3–9 hours) depending on CYP1A2 enzyme activity.3 The table below shows the last acceptable dose time by caffeine amount, targeting residual caffeine below 25–30mg at 11:30pm bedtime.
| Caffeine dose | Source example | Fast metaboliser | Average | Slow metaboliser |
|---|---|---|---|---|
| 65 mg | 1 cup chai / green tea | 8:30 pm | 7:30 pm | 6:00 pm |
| 100 mg | Espresso / 1 scoop pre-workout | 9:00 pm | 7:30 pm | 5:30 pm |
| 150 mg | Large filter coffee / most RTDs | 8:30 pm | 7:00 pm | 5:00 pm |
| 200 mg | Double shot / high-dose pre-workout | 8:00 pm | 6:30 pm | 4:30 pm |
Target sleep time: 11:30 pm. Residual threshold: ≤25 mg at bedtime. Fast = 3.5h half-life; Average = 5.5h; Slow = 8h.
A 200mg caffeinated pre-workout taken at 7:30pm means a slow metaboliser has ~110mg active at midnight. No supplement in this protocol counteracts direct adenosine receptor blockade at that level. Switch to a stimulant-free pre-workout for evening sessions, or train earlier.
The supplement stack
Three compounds. One optional fourth. Everything else marketed for sleep is either redundant, less-evidenced, or more expensive for a comparable result.
Magnesium is a cofactor for GABA receptor function and for the enzymes involved in melatonin synthesis. Deficiency — common in Indian diets low in nuts, seeds, and green vegetables — is associated with impaired sleep quality and elevated nocturnal cortisol.
Glycinate is chosen over magnesium oxide — ubiquitous in Indian supplement stores — which has poor bioavailability (4–10% vs ~80% for glycinate) and reliably causes loose stools at sleep-relevant doses. Glycinate also provides glycine, an inhibitory neurotransmitter with independent evidence for improving sleep quality.4
L-theanine increases alpha-wave brain activity — the relaxed-but-awake state associated with reduced mental chatter without sedation. It does not cause drowsiness; it reduces the arousal that prevents sleep onset.
A 2019 crossover RCT in 30 adults found 200mg theanine reduced sleep onset latency by 13 minutes and improved self-reported sleep quality without altering sleep architecture.5 Best understood as an anxiolytic adjunct — particularly useful for "mind won't stop running" insomnia rather than "can't stay asleep."
This is the most contentious number in Indian supplement culture. Every pharmacy in India sells 3mg, 5mg, and 10mg tablets. The chronobiological literature consistently points lower. Melatonin at physiological doses (0.3–0.5mg) acts as a chronobiotic — it signals the circadian system to shift into sleep phase. At 3–10mg, it acts more as a sedative, producing grogginess that outlasts its usefulness and can disrupt circadian phase the following day.6
Zhdanova et al. (2001) found no significant difference in sleep latency between 0.3mg and 3.0mg melatonin — but 0.3mg produced significantly less next-day grogginess. The 10× doses sold in India are a retail convenience, not a clinical recommendation.
The 90-minute protocol card
All timings assume a midnight sleep target. Adjust proportionally for 11:30pm or 12:30am targets.
Monthly cost breakdown
Prices from Amazon.in, April 2026. Theanine and melatonin are used only on nights where sleep quality is a concern — actual monthly cost may be lower.
What this protocol doesn't fix
Supplements can adjust timing signals and reduce arousal thresholds. They cannot address structural sleep debt from chronic short sleep, untreated sleep apnoea (common and underdiagnosed in Indian adults with central obesity), or severe anxiety disorders requiring clinical treatment. If you have used this protocol consistently for 4 weeks without improvement, the problem is upstream of supplements — a physician assessment is warranted.
