Pure Encapsulations Melatonin-SR

Sleep is the single most effective recovery tool you have — and it's the one most athletes still fight. Late training sessions, travel across time zones, race-week anxiety, and screen time all disrupt the melatonin your brain naturally produces to regulate sleep. The result is lighter sleep, more middle-of-the-night wake-ups, and mornings where you feel like you never rested at all.

Pure Encapsulations Melatonin-SR uses MicroActive® sustained-release technology to deliver 3 mg of melatonin that absorbs quickly and stays active in your system for up to six hours. That means you fall asleep faster and stay asleep through a full recovery cycle — not just the first couple of hours.

Sustained Release for Full-Night Coverage – Most melatonin supplements spike and fade within a couple of hours, leaving you wide awake at 2 a.m. MicroActive® technology provides rapid initial uptake followed by a steady, sustained presence in your bloodstream for up to six hours. You get help falling asleep and staying asleep.

Supports Your Circadian Rhythm After Disruptions – Travel days, early-morning training starts, and late-night race logistics throw off your internal clock. Melatonin-SR helps reset your sleep-wake cycle so your body adapts faster to schedule changes — critical during race week and heavy travel blocks.

Clean, Low-Dose Formula Built for Daily Use – At 3 mg per capsule, this is a precise, research-supported dose that reinforces your body's natural melatonin production without overwhelming it. No groggy hangover, no dependency concerns, and absolutely zero unnecessary additives.

Melatonin is the hormone your pineal gland produces to signal your body that it's time to sleep. It regulates your circadian rhythm — the internal clock that governs sleep, hormone release, and recovery processes.

When training stress, blue light, or travel disrupts that clock, supplemental melatonin helps your body recalibrate. The sustained-release delivery in this formula mimics the way your body naturally releases melatonin throughout the night, rather than dumping it all at once.

How to Use Melatonin-SR

Take 1 capsule 30-60 minutes before your target bedtime. The sustained-release formula starts working quickly and continues for up to six hours.

For best results, take it at the same time each night to reinforce your circadian rhythm if needed. This is especially important during travel blocks or when transitioning between training phases with different schedules.
