Source Naturals Night Rest™ with Melatonin (100 Tablets) – Bio-Aligned Formula™
If your mind races the moment your head hits the pillow, or you toss and turn trying to find deep physical relaxation, Source Naturals Night Rest (Item #SN0358) was formulated specifically for you. Unlike single-ingredient sleep pills that only address one part of rest, Night Rest is a Bio-Aligned Formula™ designed to address the three primary biological barriers to a restful night: an overactive central nervous system, tense musculoskeletal tissue, and disrupted circadian rhythms.
Why Source Naturals Night Rest Stands Out:
✓Dual-Action Magnesium Matrix: 200 mg of highly bioavailable magnesium glycinate and taurinate to calm tense muscles and soothe the nervous system.
✓Direct Calming Neurotransmitters: 100 mg of GABA paired with 502 mg of glycine to help quiet mental chatter.
✓Circadian Clock Reset: 4 mg of pure melatonin to signal your body that it is time to drift off naturally.
✓Time-Tested Botanical Infusion: Passionflower, skullcap, and concentrated 4:1 chamomile extract for holistic botanical relaxation.
✓Flexible Dosing: Scored tablets make it simple to start with a half tablet or take up to two depending on your individual sensitivity.

How Night Rest Works: The 3 Body Systems Explained in Layman's Terms
Most common sleep aids rely exclusively on heavy doses of melatonin or sedating antihistamines. While they might knock you out, they often leave you feeling groggy the next morning because they overlook why you could not sleep in the first place. Source Naturals takes a systemic approach by synchronizing three distinct body systems:
1. The Mind (Brain & Nerves)
When you cannot shut off your thoughts, your brain is firing excitatory signals. Night Rest provides GABA and Glycine – the biological "brakes" of the brain – to gently lower neurological volume and ease tension.
2. The Body (Muscles & Heart)
Physical tension, tight shoulders, and restlessness make settling down difficult. Organic Magnesium Glycinate & Taurinate encourage tight muscle fibers to relax and promote a calm, steady heart rhythm.
3. The Rhythm (Circadian Clock)
Exposure to artificial light and screen time suppresses your pineal gland. A 4 mg dose of Melatonin replicates your natural bedtime signal, prompting you to feel drowsy right on schedule.
Deep Dive: Ingredients Backed by Clinical Sleep Science
Every ingredient in Source Naturals Night Rest was selected for its specific biochemical role. Here is what modern clinical research tells us about how each component supports healthy, restorative sleep:
1. Magnesium Chelate Complex (200 mg – 48% DV)
Magnesium acts as a natural gatekeeper for NMDA receptors (excitatory nerve pathways) and helps activate calming parasympathetic pathways. Instead of cheap magnesium oxide, which frequently causes digestive upset and is poorly absorbed, Night Rest utilizes magnesium glycinate and taurinate.
Scientific Evidence: A double-blind, randomized clinical trial published in the Journal of Research in Medical Sciences demonstrated that oral magnesium supplementation significantly improved sleep time, sleep efficiency, and melatonin concentrations while decreasing sleep onset latency and morning serum cortisol levels (Abbasi et al., 2012).
2. Glycine (502 mg)
Glycine is a soothing amino acid that lowers your core body temperature before sleep by promoting vasodilation (widening of peripheral blood vessels). Dropping core body temperature is the body's natural cue to enter deep, slow-wave sleep.
Scientific Evidence: Polysomnographic research published in Sleep and Biological Rhythms verified that glycine ingestion prior to bedtime significantly shortens the time required to fall asleep and stabilizes sleep architecture without causing next-day hangover sensations (Yamadera et al., 2007).
3. GABA – Gamma-Aminobutyric Acid (100 mg)
GABA is the chief inhibitory neurotransmitter in human physiology. It prevents neurological over-firing when thoughts are racing, helping soothe the nervous system into a resting state.
Scientific Evidence: Clinical evaluations indicate that oral GABA administration increases alpha brain waves (associated with calm relaxation) while suppressing beta brain waves (associated with active stress and worry) within 60 minutes of consumption (Abdou et al., 2006).
4. Melatonin (4 mg)
Melatonin is a hormone produced by the pineal gland that coordinates the circadian sleep-wake cycle. In modern environments filled with blue light from smartphones, computers, and TVs, natural nighttime melatonin synthesis is commonly postponed.
Scientific Evidence: A rigorous meta-analysis of nineteen clinical trials comprising 1,683 subjects published in PLoS ONE confirmed that melatonin significantly decreases sleep onset latency, increases total sleep duration, and boosts overall subjective sleep quality (Ferracioli-Oda et al., 2013).
Centuries of traditional European and American herbalism are united with standardized science. Chamomile (standardized 4:1 extract) contains the flavonoid apigenin, which binds to specific calming receptors in the brain. Passionflower and Skullcap (Scutellaria lateriflora) synergistically support peaceful muscular tone and nighttime comfort.
Scientific Evidence: In a double-blind trial, Passiflora incarnata demonstrated measurable improvements in sleep quality ratings over placebo (Ngan & Conduit, 2011). Similarly, randomized clinical investigations confirm that chamomile extract markedly enhances sleep scores among individuals experiencing nighttime sleep difficulties (Adib-Hajbaghery & Mousavi, 2017).

Usage Instructions, Dosage Protocol & Best Practices
Because everyone's brain chemistry and sensitivity to melatonin and calming herbs are unique, finding your personal "sweet spot" is the key to waking up refreshed rather than sluggish.
Suggested Use & Titration:
First-Time Users: Begin by taking 1/2 to 1 tablet 30 to 60 minutes before bed. Many individuals find that half a tablet (yielding 2 mg of melatonin and 100 mg of magnesium) provides sufficient relaxation without leaving residual morning sleepiness.
Standard Serving: Take 1 to 2 tablets with a small glass of water 30 to 60 minutes before you intend to sleep.
Maximum Intake: Do not exceed 2 tablets in a 24-hour period unless directly supervised by a qualified medical professional.
Sleep Hygiene Tips to Maximize Results:
✓Dim Overhead Lighting: Melatonin works in tandem with darkness. Dim indoor lamps 45 minutes before sleep to amplify your body's response.
✓Avoid Heavy Meals Late: Try to take Night Rest on an empty or light stomach to speed digestion and nutrient uptake.
✓Maintain a Cool Bedroom: Glycine promotes nighttime heat dissipation; setting your thermostat between 65°F and 68°F complements this physiological cooling process.

Frequently Asked Questions (FAQ)
Will Source Naturals Night Rest leave me groggy the next morning?
Most users wake up feeling refreshed because Night Rest combines low-to-moderate doses of targeted botanicals and amino acids rather than relying on overwhelming amounts of sedatives. If you experience mild morning grogginess, try reducing your intake to half a tablet or taking it an hour earlier in the evening.
How much melatonin is in each serving of Night Rest?
A full two-tablet serving delivers 4 mg of melatonin. If you cut the tablet in half along its score line, you receive 1 mg of melatonin, while one single whole tablet provides 2 mg. This allows you to tailor your melatonin intake to your body's sensitivity.
How does Night Rest differ from plain melatonin supplements?
Plain melatonin only triggers the biological "time to sleep" signal in your brain; it does not ease tense muscles or stop racing thoughts. Night Rest pairs melatonin with magnesium to relax muscles, GABA and glycine to quiet nervous chatter, and chamomile and passionflower to soothe mental tension.
Can I take Night Rest alongside prescription sleep medicines or antidepressants?
No. Night Rest should not be combined with prescription sleep aids, tranquilizers, MAO inhibitors, or corticosteroids without direct guidance from your prescribing physician. Combining botanical sedatives with prescription sleep medications can cause excessive central nervous system depression.
Is Source Naturals Night Rest non-habit forming?
Night Rest contains nutritional amino acids, dietary minerals, and gentle traditional herbs that do not cause physical dependency like pharmaceutical benzodiazepines or "Z-drugs." However, it is intended for occasional sleeplessness. Practicing consistent bedtime habits is always recommended for long-term sleep wellness.
What size bottles are available, and how long does a 100-tablet bottle last?
This bottle contains 100 tablets (Item #SN0358). If you take the full 2-tablet serving nightly, the bottle provides a 50-day supply. If you take 1 tablet nightly, it provides a 100-day supply. Source Naturals also produces Night Rest in 50-tablet (SN0357) and 200-tablet (SN1387) varieties.
