HERE FOR THE GOOD PART
For the nights you want back.
You give the day plenty. Give your nights a little care, too.
YOUR EVENING. RECLAIMED.Unwind physical tension in muscles & nerves†
Most sleep supplements hide tiny mineral doses behind compound weights or cheap magnesium oxide. Every Nightspan scoop delivers a true 250 mg of elemental magnesium from fully reacted magnesium bisglycinate to support normal muscle and nerve relaxation before bed.†
Deep, restorative rest—100% melatonin-free†
Stop overriding your endocrine rhythm with synthetic sleep hormones. Nightspan unites 3,000 mg of free-form glycine, 250 mg elemental magnesium, 200 mg L-theanine, 28 mg saffron, and 15 mg zinc so you can use it every single night and wake up clear-headed.†
Fuel cellular recovery & energy metabolism†
Magnesium powers over 300 enzymatic reactions, helping your cells produce energy and maintain electrolyte balance while you rest—supporting true cellular restoration without a single stimulant.†
Structural support for bone & protein synthesis†
Beyond your evening wind-down, 250 mg of elemental magnesium and 15 mg of chelated zinc contribute directly to bone health and normal protein and DNA synthesis overnight.†
Replaces 5 separate nightstand pill bottles
Matching Nightspan's exact doses with capsules means swallowing 6 to 8 pills a night across five separate bottles ($56.57/month weighted retail value). Nightspan puts the entire clinical lineup into one effortless evening glass.

You don't have a melatonin deficiency. You have an unquieted evening nervous system.
You carried the entire day—the decisions, the deadlines, the messages, and everyone else's priorities. Yet the moment your head hits the pillow and the room goes dark, your nervous system stays locked in high gear. You replay conversations, run through tomorrow's calendar, or snap awake at 2:47 a.m. staring at the ceiling. Your body is spent, but your mind never got the signal to power down.
Read the full story
Melatonin gummies try to solve that by flooding your receptors with a synthetic hormone—often trading a quick knockout for a 3 a.m. rebound and a heavy morning hangover. And standard sleep capsules simply cannot fit the 3,000 mg of free-form glycine and 250 mg of elemental magnesium your body actually uses to cool down and settle in without forcing you to swallow a handful of chalky pills at bedtime.
Nightspan solves both problems in one smooth evening scoop. Three full grams of free-form glycine pair with 250 mg elemental magnesium bisglycinate, 200 mg calming L-theanine, 28 mg standardized saffron extract, and 15 mg chelated zinc. Every milligram is printed right on the front—so you can close the day decisively and wake up ready to own your morning.†
SOUND FAMILIAR?
Bedtime shouldn’t feel like another shift.
- You get into bed exhausted, and your brain immediately opens twenty mental tabs.
- Melatonin leaves you groggy and flat through your first two hours of the morning.
- You're tired of swallowing 6 to 8 giant magnesium and amino acid capsules before bed.
- Waking up at 2:47 a.m. steals the deep, unbroken rest your tomorrow depends on.
MAKE ROOM FOR THIS.
Your evening, on your terms.
- A physical and mental exhale within 30 to 60 minutes of your evening glass.†
- Steady, hormone-free sleep support you can rely on every night of the week.†
- One clean scoop that replaces five separate supplement jars on your nightstand.
- Crisp, clear-headed mornings where you wake up restored before the alarm even finishes.†

SIDE-BY-SIDE FORMULA AUDIT · ZERO MELATONIN, ZERO COMPROMISE
Why Nightspan beats melatonin gummies and single-mineral chews on every count.
A magnesium gummy gives you one mineral and stops. Lemme Sleep floods you with 5 mg of synthetic melatonin and trace 20 mg magnesium. Nightspan delivers five full-dose evening actives—3,000 mg free-form glycine, 250 mg elemental magnesium, 200 mg L-theanine, 28 mg saffron, and 15 mg zinc—with zero melatonin.

SP NUTRITION
A single-mineral gummy leaves 4 evening actives out.
Its listed formula has no separate 3,000 mg free-form glycine dose, no 200 mg L-theanine, no 28 mg saffron, and no chelated zinc. Nightspan puts all four alongside 250 mg of true elemental magnesium in one evening scoop.
LEMME SLEEP
5 mg of synthetic melatonin—and a tiny fraction of the calm minerals.
Lemme Sleep lists just 50 mg L-theanine and 20 mg magnesium citrate alongside 5 mg melatonin. Nightspan delivers 4× the L-theanine (200 mg) and 12.5× the elemental magnesium (250 mg from bisglycinate), plus 3,000 mg free-form glycine, 28 mg saffron, and 15 mg zinc—100% hormone-free.

See the labels behind the comparison
Amounts are per labeled serving: two gummies for each named competitor and one Nightspan serving. “Not included” refers to these specific formulas. †SP’s page states 400 mg magnesium bisglycinate; its label also says 400 mg magnesium from 400 mg bisglycinate chelate. No elemental conversion or magnesium-dose ranking against SP is used here. Nightspan’s magnesium amount is elemental. Lemme’s Supplement Facts panel declares 20 mg elemental magnesium, supplied as citrate. The 4× and 12.5× comparisons are against Lemme Sleep only.

FIVE SEPARATE BOTTLES. ONE NIGHTSPAN FORMULA.
What would these ingredients cost separately?
Across 44 single-ingredient capsule listings, the quantity-weighted retail cost for Nightspan’s five daily ingredient amounts comes to $56.57 per 30 days. Nightspan puts all five into one 30-serving pouch.
| Ingredient | Daily amount | 30-day amount | Low | Weighted | High |
|---|---|---|---|---|---|
| Free glycine | 3,000 mg | 90,000 mg | $7.32 | $13.87 | $36.00 |

THE MATH, IN PLAIN VIEW
How we calculated buying it separately
We show the cost of the ingredient amount used in 30 days, then show the whole-bottle checkout cost separately. Those numbers answer different questions.
REAL BOTTLE · BEST NATURALS GLYCINE · OCTOBER 9, 2026
90 capsules cover 30 days of Nightspan’s glycine amount.

50% used90 capsules remain from the 180-capsule bottle
30-day amount allocated$7.50
Whole bottle paid upfront$14.99
The comparison counts the half-bottle amount used. A customer still buys the full bottle and keeps the other 90 capsules.
12 GLYCINE LISTINGS · WEIGHTED RESULT
$13.87 is the glycine estimate—not the cost of that one bottle.
Across the 12 listings, we divide $271.92 in bottle prices by 1,765,000 mg of labeled glycine, then multiply by Nightspan’s 90,000 mg 30-day target.
$271.92 ÷ 1,765,000 mg × 90,000 mg = $13.87
The same calculation is done ingredient by ingredient. The five weighted amounts add to $56.57 for 30 days across the full 44-listing sample.
THREE DIFFERENT COMPARISONS
A shopping basket is not the weighted estimate.
$102.85 upfront buys the bottles selected for the lowest normalized 30-day costs; those bottles’ ingredient portions allocate to $37.65. That is a different basket and method from the $56.57 weighted estimate.
$68.81 upfront is the sample’s lowest-cash basket; the 30-day ingredient portions in that basket allocate to $47.11.
$56.57 is the separate quantity-weighted estimate from 44 listings—not either basket’s checkout total.
How the 30-day allocation works
For each listing, we normalize the label to ingredient milligrams per capsule, then calculate: bottle price × (Nightspan’s 30-day target ÷ total labeled ingredient in the bottle). The weighted ingredient cost is (sum of listing bottle prices ÷ sum of labeled bottle quantities) × 30-day target. We add the five ingredient results.
Magnesium and zinc use elemental amounts. Saffron listings match the ≥3.5% Lepticrosalides specification. Proportional capsule costs may not equal a whole-capsule routine.
Open the full 44-listing price set and sources
Capsule equivalents and bottle shares are quantity-allocation math, not dosing instructions. A result above 100% means the target quantity exceeds one bottle. Customers buy whole packages, so upfront checkout cost differs from these prorated allocations. Prices are a dated snapshot, before tax, shipping, coupons or Subscribe & Save; offers change. This compares labeled ingredient quantities, not Nightspan’s manufacturing cost, clinical equivalence, or a guaranteed checkout price. Full source basis and calculations are retained in the project research record.

LET’S TALK ABOUT IT.
Here’s why it earns its place.
I already take magnesium. Why upgrade to Nightspan?
Even if you take magnesium, buying separate bottles to match Nightspan's 3,000 mg free-form glycine, 250 mg elemental magnesium, 200 mg L-theanine, 28 mg standardized saffron, and 15 mg zinc costs $56.57 every 30 days ($102.85 upfront across 5 bottles) and requires swallowing 6 to 8 capsules every night. Nightspan gives you all five in one scoop for less.
I hate how melatonin makes me feel the next morning. Is there any in here?
Zero. Nightspan is 100% melatonin-free and hormone-free, engineered specifically for people who want deep nighttime rest and crisp, clear-headed mornings.†
Why is Nightspan a powder instead of capsules?
Physics. Three grams of glycine plus 250 mg of elemental magnesium bisglycinate, L-theanine, saffron, and zinc physically cannot fit into one or two capsules—it would take 6 to 8 large pills every night. One smooth scoop in water delivers the full clinical mass effortlessly.
What if it doesn't work for my routine?
You are protected by our 90-day money-back guarantee from delivery. Put Nightspan to the test for a full 90 nights; if you aren't thrilled, request a purchase-price refund with no return shipping required.
GOOD QUESTIONS
Let’s clear a few things up.
How much glycine is in one serving?
Every scoop delivers a full 3,000 mg (3 g) of standalone free-form glycine—completely separate from the glycine bound inside our magnesium and zinc bisglycinate chelates.
How is Nightspan different from a magnesium-only product?
Magnesium-only supplements leave out the other four pillars of evening rest. Nightspan combines 250 mg elemental magnesium with 3,000 mg free-form glycine, 200 mg L-theanine, 28 mg standardized saffron extract, and 15 mg elemental zinc in one scoop.
Does Nightspan contain melatonin?
No. Nightspan is melatonin-free. It supports your body's natural wind-down without synthetic hormones or morning grogginess.†
What form of magnesium is used?
Nightspan supplies 250 mg elemental magnesium as fully reacted magnesium bisglycinate. The 250 mg is the true elemental magnesium yield itself; the full bisglycinate compound weighs more.
Is this just glycine powder?
No. Nightspan pairs its full 3,000 mg free-form glycine serving with 250 mg elemental magnesium, 200 mg L-theanine, 28 mg standardized saffron, and 15 mg elemental zinc in one complete night-time formula.
Who is Nightspan for?
For adults who want a complete, high-dose night-time formula with glycine, magnesium, L-theanine, saffron and zinc—without melatonin or 8-capsule pill fatigue.
