One Nightspan formula, three ways to arrange your purchase
Every Nightspan option begins with the same five-active formula. You can keep the first order small, buy more of the powder in one transaction, or consider a separate arrangement for repeat deliveries. Once you want the formula, the offer should fit the way you want to bring it into your life.
The existing planned options below make the distinction visible. These are planned product subtotals, not approved final charges; shipping, tax, availability, and final terms will be shown before purchase.
| Planned option | Exact contents | Planned product price | What makes the choice different |
|---|---|---|---|
| One-time single jar | One Nightspan jar | $89 once | A smaller first order with no automatic renewal |
| One-time three-jar package | Three Nightspan jars | $165 once; $55 per jar | More of the same formula in one purchase, with no automatic renewal |
| Single-jar replenishment | One Nightspan jar per proposed delivery | $55 every 30 days, planned | A separate proposed recurring purchase arrangement |
A three-jar subscription is a different proposed option whose price and cadence are not approved. It does not inherit the one-time three-jar price. No subscription enrollment, payment, order, or reservation is created by selecting a preference here.
The one-time three-jar package reaches the same planned $55 unit price as single-jar replenishment, with a different commitment: $165 for three jars at once and no automatic renewal. Replenishment proposes $55 for one jar every 30 days, with recurring charges. If you want the smaller one-time order, the $89 jar keeps that choice available. The detailed comparison below puts the savings and first outlay side by side.
Why begin the formula with glycine?
Glycine gives Nightspan a connection to a recognizable hope: a more satisfying night. Small human research examined 3 g glycine in people dissatisfied with their sleep. The cited study found improvements in participants' sleep ratings and the time taken to fall asleep, with unchanged sleep architecture. It included Ajinomoto-affiliated researchers and did not test Nightspan. Read the glycine study.
That finding is worth your attention when better sleep is why you began looking. It is also specific enough to explain a formulation choice. Nightspan starts with 3,000 mg of free-form glycine: 3 g, the amount in the cited study. The numerical connection helps explain the foundation of the product; it does not establish the same outcome from a five-active blend.
Nightspan's working panel makes free-form glycine its own entry. You do not have to guess how much was intended or derive the number from the name of a mineral form. The 3,000 mg is visible alongside the other active amounts.
There is now a reason for this ingredient to have a place in the evening you pictured. You may have arrived hoping for an easier transition from the day into sleep, or simply to wake with a more satisfying impression of the night. Glycine's research makes the ingredient relevant to that interest. The next part of Nightspan's case is what the additions bring alongside it.
A glycine foundation with a broader evening approach
Magnesium bisglycinate adds a specific mineral form investigated in adults reporting poor sleep. L-theanine brings another amino acid with its own sleep-research history. Saffron introduces a botanical approach based on a standardized extract, with the final material still pending. Zinc completes the formula in a supporting nutrient role. These selections make the jar more than a glycine purchase.
The appeal is strongest when those additions answer interests you already have. Perhaps glycine first drew you in, but you also wanted to explore magnesium in its bisglycinate form and the botanical approach represented by saffron. Nightspan lets you choose that broader selection, including its L-theanine and zinc, as a single powder with its amounts already set out.
You can picture what that means at home. The ingredients you wanted to explore have a single place on your shelf. There is one product to keep on hand, with its composition already chosen. For someone who welcomes the whole design, that is a tangible reason to prefer this powder to continuing the search ingredient by ingredient.
The finished Nightspan combination has not been clinically tested. The individual ingredients explain its design; choosing them together gives you the specified selection in one powder.
What is in the jar, and why the details matter
This is the complete working formula. Amounts, final material matches, and label directions remain subject to approval.
| Active | Working amount | Working form or specification |
|---|---|---|
| Glycine | 3,000 mg | Free-form |
| Magnesium | 250 mg elemental | Fully reacted bisglycinate |
| L-theanine | 200 mg | Free-form |
| Saffron extract | 28 mg | Planned affron-type source; at least 3.5% Lepticrosalides; final material pending |
| Zinc | 15 mg elemental | Bisglycinate |
You can identify the free-form glycine separately
The formula includes both free-form glycine and magnesium bisglycinate. These are two entries in the same product. Reading them separately keeps the intended design clear and gives you a useful way to compare the working panel with another product.
The 3,000 mg free-form glycine entry remains distinct from the glycine in a mineral's compound name. The worked Supplement Facts guide shows how to read that separate entry alongside elemental mineral amounts and pending powder weight.
Nightspan is the blend containing that glycine foundation and all four additions. Its identity stays the same whether you choose one jar or three.
The mineral amounts are printed as elemental
Magnesium and zinc are expressed as their elemental amounts: 250 mg and 15 mg, respectively. The form is identified in the next column. This lets you compare like information rather than mistaking the weight of a named compound for the stated amount of mineral.
For someone already drawn to magnesium, Nightspan brings the mineral into the same powder as the glycine foundation. That is one reason this formula could earn a place in your evening. If you already use magnesium or zinc, place the panels together and account for overlapping amounts before adding a blend; the actual mineral quantities matter to that choice.
Nightspan's proposed magnesium form is fully reacted bisglycinate; zinc is listed as bisglycinate. The specification is information about the formula. It is not a claim that this product has demonstrated superior absorption or that a particular form will suit every reader.
The saffron material is part of the choice
Nightspan's working specification names an intended standardized saffron approach. The final source and material match are still pending. That distinction is worth keeping in view because evidence about a botanical depends on more than the familiar name of the plant.
The proposed 28 mg extract, planned affron-type source, and at least 3.5% Lepticrosalides specify the botanical approach Nightspan is being developed to include. For a reader interested in the standardized saffron research, that is a particular reason to look at this design. Confirming the final source is part of delivering the ingredient that attracted your interest.
If that material identity is essential to your preference, wait for confirmation before committing. You can still see the intended role now: a botanical beside the amino acids and minerals, in a formula built around the glycine amount that began the case. Nightspan's appeal depends on these actual selections coming together.
You can also read the Nightspan product details. The full working panel remains here so that deciding about the offer does not require another page to learn its contents.
Why these ingredients belong beside glycine
The evening you want is still the reason for exploring the details. You hope to sleep well and welcome the next morning with a satisfying night behind you. The ingredient research below concerns parts of that interest, and explains why Nightspan's selection extends beyond glycine alone.
Magnesium bisglycinate adds a specific mineral approach
Magnesium is an essential mineral with normal nerve and muscle functions. A trial of its bisglycinate form in adults reporting poor sleep found a small improvement in insomnia-symptom scores; this does not establish the effects of Nightspan or that everyone needs supplemental magnesium. Its working elemental amount gives you a specific entry to evaluate. NIH magnesium information, the magnesium trial.
The mineral form gives you something concrete to choose alongside glycine. When magnesium was already part of the approach you wanted, Nightspan brings it into the same powder at 250 mg elemental magnesium as fully reacted bisglycinate. The combination's appeal is those selections together; this ingredient trial does not demonstrate that their effects add up.
L-theanine brings another sleep-research interest
L-theanine brings another amino acid into the design. A review found improvements in some self-rated sleep measures across interventions containing it, while noting limited research on L-theanine alone and uncertainty about dose and duration. Nightspan's working 200 mg is a formulation choice, not a universal effective-dose claim. The L-theanine review.
Being able to call a night a good one is part of what many people mean by sleeping better. That makes self-rated outcomes relevant to the hope behind this purchase. Theanine is included as a distinct 200 mg free-form active, giving that separate research interest a place beside Nightspan's glycine foundation.
Saffron introduces the botanical part of the design
Saffron adds a botanical with human research on self-rated sleep using a specifically standardized extract. The findings for that extract do not automatically apply to every saffron material. Its inclusion is worth evaluating through the actual source and working amount, with the final material match still to be established. The saffron trial.
For someone who wanted to explore a botanical as well as amino acids and a mineral, saffron gives the formula a broader character. Its research interest is human sleep experience. Its identity is material-specific. Both belong in the reason you may want the proposed extract together with Nightspan's other actives.
Zinc has a supporting nutrient role
Zinc supplies a supporting essential mineral involved in normal protein production and cell processes. That nutrient role does not establish extra sleep benefits from the powder. The 15 mg elemental working entry is part of the full panel you should account for. NIH zinc information.
The zinc entry is included as bisglycinate. It completes the proposed nutrient design and needs to fit the products you already use. If keeping zinc separate matters to you, that remains a reason to prefer a different arrangement, even when glycine first drew your attention.
Together, the ingredient reasons explain a particular preference: glycine gave you a starting point; magnesium's form appealed; theanine and standardized saffron broadened your interest; and the supporting zinc suited the blend you wanted. Nightspan gathers that selection in one powder. It is a considered purchase for an evening you care about, with the finished combination still untested.
When that selection fits, the practical benefit is easy to picture: the actives you wanted, already combined in one powder. You accept fixed amounts in exchange for that convenience.
The wider glycine story stays connected to the actual product
Glycine has normal roles beyond the evening-supplement discussion. It appears in collagen's repeating structure, is a component of glutathione, and participates in the body's pathway for making creatine. Those connections explain biological interest; they do not establish skin, antioxidant, strength, or energy outcomes from Nightspan. Collagen structure, glutathione definition, creatine synthesis.
These roles give glycine a broader biological identity than a bedtime label suggests. They can enrich your interest in the ingredient while Nightspan remains the same defined five-active formula. A powder containing glycine is not automatically interchangeable with collagen or creatine.
It also contains no NAC. GlyNAC research examines glycine combined with N-acetylcysteine, including a trial in older adults; that is a different intervention and not evidence of age reversal or longer life from Nightspan. The GlyNAC trial.
A separate study used 15 g glycine daily in adults with metabolic syndrome. Its amount and population cannot substantiate metabolic, blood-pressure, or blood-sugar claims for this 3 g five-active blend. Do not increase servings to imitate that research: more powder also increases the other four actives. The higher-dose glycine study.
The broader story remains available in the product information. You can appreciate that biology and still choose Nightspan for the evening approach that first attracted you. The next comparison is practical: whether this combination gives you more of what you want from the product you bring home.
Give the alternatives a serious look
Pure glycine: the appeal of a narrow decision
Pure glycine is a credible alternative when that is the only new ingredient you want. It keeps the purchase narrow and preserves the freedom to decide separately about magnesium, theanine, saffron, and zinc.
That simplicity matters if your existing products have been selected for particular reasons. A glycine-only purchase can fit around those choices. It also suits someone who is interested in the leading ingredient and does not want to choose the additions.
Nightspan earns a preference when you want the 3 g glycine foundation together with its specified magnesium form and the additional amino acid and botanical approach. With zinc included as a supporting nutrient, the powder gathers that broader selection into one product. Those are the additions you would be paying to have together.
This is a decision about product design and convenience. The presence of more ingredients does not establish that Nightspan will produce a greater sleep effect than glycine alone. The stronger reason to choose it is wanting the whole proposed formulation at the disclosed amounts.
Your existing magnesium product: the appeal of familiarity
An existing product can have a real advantage: you know what it contains and how it fits your current arrangement. There is no need to dismiss that familiarity to appreciate a different formula.
The reason to consider a change is what you want beside that mineral. Glycine's 3 g sleep research may have caught your interest, followed by theanine and saffron. Nightspan makes that broader approach available as one proposed formula if its magnesium amount and supporting zinc also fit.
If retaining a particular magnesium amount or brand matters more, your existing arrangement keeps that flexibility. If you welcome Nightspan's whole composition, its powder offers one place for those related interests.
Account for the amounts across products before deciding what belongs together. A blend is a whole product choice. The purpose of seeing the individual entries is to make that choice deliberate, including the minerals that may already appear elsewhere in your supplements.
Separate supplements: the appeal of control
Choosing separate ingredients gives you control over the brands, forms, and amounts you select individually. It lets you keep one product while deciding differently about another. For someone who enjoys building an arrangement piece by piece, that can be a meaningful benefit.
There is also practical work involved: several panels, purchases, containers, and reorder decisions. You may enjoy that involvement. Or, at the end of a full day, you may welcome having the ingredient selection settled in one powder.
That is Nightspan's practical advantage when the formula fits. You give up the ability to adjust each active independently and gain the group as a single product. Your evening has one selected powder to make room for, rather than several separate ingredient purchases to manage.
The cost of separate supplements depends on the ingredients, quantities, and products you would actually buy. Compare that basket with the Nightspan option you want. The powder's convenience can be valuable even when it is not the cheapest way to purchase every listed ingredient.
Another evening blend: the appeal depends on its actual panel
Two products can both be melatonin-free and ask you to choose different ingredients or formats. If Native Sleep is on your shortlist, compare its capsule formula with Nightspan, including the dated ingredient evidence and purchase terms.
Nightspan's answer is a 3,000 mg free-form glycine foundation with the four named additions and a melatonin-free composition. It gives a particular set of ingredient interests one home. That is the design to compare with the other jar you are considering.
| Approach | What you retain | What you decide |
|---|---|---|
| Pure glycine | A narrow ingredient purchase | Whether glycine alone is the product scope you want |
| Your current magnesium product | Familiarity with an existing selection | Whether you want to change the overall ingredient arrangement |
| Separate products | Individual control over each selection | Whether that flexibility is worth managing several products |
| Nightspan | The selected five-active formula in one powder | Whether this full panel fits your preferred approach |

When the complete selection earns its value
The value of Nightspan begins before the package size. It is the value of getting the formula you actually wanted to choose: the glycine foundation, a specific magnesium approach, theanine and standardized saffron, with supporting zinc accounted for.
Perhaps the research opened the door, but the complete design is what makes this powder appealing. You can picture it at home because the ingredients now have reasons behind them. The evening you wanted to give more attention has led to a product you can name and a composition you understand.
That gives a larger package a legitimate place in the next decision. If you want more of this formula on hand, a lower unit cost is useful. If the formula has not earned your preference, a lower unit cost cannot supply the missing reason. Quantity follows the product you want to own.
When Nightspan is what you want on your shelf, the package comparison becomes useful.
Which kind of Nightspan purchase are you making?
Now bring the choice back to your home and your budget. You want Nightspan to have a place in your evening; the remaining question is how much to bring home and how to arrange future purchases. These three situations give each option a practical purpose.
You want a smaller first order
You like Nightspan's glycine foundation and the ingredients beside it, and want the smaller one-time order. At the planned $89 product subtotal, one jar asks for less upfront than the planned $165 three-jar package. It does not renew automatically.
The reason to select it is the size of the purchase. It is not a promise that one jar is a sufficient test of a medical outcome, nor does it represent a defined period of use while serving information remains unsettled.
You can want to give your evening some attention and still prefer a limited first purchase. One jar lets the size of the order reflect that preference. You receive the complete formula you chose, with the freedom to make a separate decision about any later order.
You want more of the same formula on hand
You have a clear preference for Nightspan and want several jars in one purchase. The planned $165 package supplies three of the same powder at $55 per jar. Its appeal is having more of the formula you want at a lower unit cost than three planned one-time single-jar purchases.
This can suit someone who would like the ingredient choice settled and the next jars already on the shelf. The planned $76 above a single-jar order buys two additional Nightspan jars now. You make one purchase for that quantity and retain the choice about whether and when to order again. That is a different kind of convenience from agreeing to future charges.
The larger order should follow confidence about the formula's fit and the quantity you want. A lower unit price cannot settle whether you want the ingredients. When that decision is already made, it can help you choose how to purchase them.
You prefer arranging repeat orders
Replenishment is a different preference. It concerns a proposed future delivery arrangement, with recurring charges and a schedule that must be clearly stated before enrollment. It is useful to evaluate separately from the question of how many jars you want in a one-time order.
Someone who likes arranging purchases in advance may find that approach attractive. Someone who wants to decide about every future order may prefer one-time purchasing. The important distinction is knowing which arrangement you have chosen and what its actual terms would be.
Nightspan's proposed single-jar replenishment is $55 every 30 days. That arrangement could appeal if you prefer to organize repeat purchases in advance; its cadence still needs to suit your actual use once final directions are available. A three-jar subscription remains separately unpriced with its cadence pending.
Understand the package value in real numbers
The three-jar package has a clear economic attraction if you want that quantity. At the planned figures, three one-time single jars cost 3 × $89 = $267. The planned three-jar package is $165, so the same three jars cost $102 less, a reduction of about 38.2%. Each jar works out to $55 instead of $89.
These are planned product subtotals, with shipping, tax, and final terms still pending. The $267 comparison comes from three of the existing planned $89 single-jar options. It is a same-quantity comparison, not a former selling price or an estimate for another brand.
Your first outlay tells the other part of the story. Compared with buying one $89 jar, the $165 package asks for $76 more upfront and gives you two additional jars. You receive three times the jars for about 1.85 times the initial product subtotal. That can make the larger purchase attractive without disguising its size.
| The comparison | Planned arithmetic | What it means for your choice |
|---|---|---|
| Three jars bought as single-jar purchases vs. one three-jar package | $267 vs. $165; $102 less, about 38.2% | The package costs less for the same three jars |
| A first one-jar order vs. a first three-jar order | $89 vs. $165; $76 more | The additional first outlay brings two extra jars |
| Unit cost in the three-jar package | $165 ÷ 3 = $55 | A lower jar cost in exchange for buying more at once |
| Single-jar replenishment vs. the three-jar one-time package | Both $55 per jar, planned | One arrives on a recurring schedule; three are bought together without renewal |
The package therefore suits a reader who wants three jars of this formula and values paying less for that quantity. The one-time single jar suits a reader who wants the lower initial subtotal. Both are understandable ways to make room for the same evening powder. The savings apply to the product you receive, with no promised difference in results between order sizes.
Compare the commitment as well as the unit price
The shared $55 unit price does not make replenishment and the three-jar package equivalent arrangements. The planned one-time package asks for $165 and supplies three jars together. Proposed single-jar replenishment asks for $55 per delivery every 30 days and establishes recurring purchases. One spreads product purchases across deliveries; the other buys the quantity upfront.
If you want the $55 planned unit price while deciding separately about every future order, the one-time three-jar option has a particular advantage. If arranging repeat deliveries is what you value, consider replenishment on its full renewal and cancellation terms. Choose the purchase mode that gives you the arrangement you want.
The proposed 30-day recurring cadence does not establish how long one jar lasts. Final serving information is pending, so no use duration can be assigned to either package. A study duration does not determine the quantity you should buy.
The published first-batch proposal is a 90-day purchase-price refund without returning the jar. Its eligibility, exclusions, window start, request method, tax and shipping treatment, and processing timing still need final terms. It does not promise a sleep outcome. Read the current shipping and returns status, then review the approved full charges and applicable policy before payment becomes available.
Questions worth answering before you choose
Is Nightspan the same product as Dayspan Glycine?
Yes. Nightspan is the public name for this Dayspan Glycine product. It is the five-active evening powder shown on this page, with 3,000 mg of free-form glycine and the four other working actives. The product details remain available at the Glycine route.
The name identifies the same complete formula across the product details and package choices. There is no second sleep product required alongside it, or separate plain-glycine version behind this offer.
I mainly want glycine and magnesium. Why accept saffron and 15 mg zinc as well?
Saffron adds a botanical approach with research on self-rated sleep using a particular standardized extract. Zinc adds an essential mineral with a supporting nutrient role. They change what you are buying: Nightspan includes both, as well as 200 mg free-form L-theanine, rather than stopping at glycine and magnesium.
The additions earn their value when your interest has broadened to include theanine's and saffron's separate research. Receiving them together then becomes an advantage. The final saffron material still needs confirmation, especially when that identity is decisive for you.
The zinc entry is a different question. Its presence is part of the proposed nutritional design, not a reason to assume an extra sleep effect or ignore a mineral you already take. If you want to keep zinc separate, or the saffron addition does not appeal, glycine and magnesium products selected individually preserve that control.
Choose Nightspan when you welcome those five entries together. That is the reason for the blend to earn your preference before a multipack price attracts you.
I already take magnesium or zinc. How should I approach this choice?
Put the complete working panel beside the products you already use. Nightspan proposes 250 mg elemental magnesium and 15 mg elemental zinc, along with its other actives. Identify the overlap before deciding what belongs in your arrangement.
The question is whether you want this complete blend, not whether two products can be assumed to fit together because both contain familiar nutrients. You may value keeping an existing selection and choosing other ingredients separately. Or the Nightspan design may be closer to the combined product you have been looking for.
A clinician or pharmacist can help with individual questions involving medicines, conditions, or total supplement intake. Nightspan is not for children. Pregnancy, nursing, medication use, or a medical condition warrant appropriate clinical guidance; kidney conditions are relevant when considering supplemental magnesium.
Does the melatonin-free formula promise better sleep without the drawbacks of melatonin?
The formula is melatonin-free. That answers a composition preference; it does not establish a comparative safety or effectiveness claim. The relevant evidence concerns the individual ingredients and the specific interventions described in their sources.
The finished Nightspan combination has not been clinically tested, and no particular sleep outcome or result date is promised. Your reason to choose it can still be specific: interest in the ingredient rationale, a preference for the complete panel, and the convenience of that selection in an evening powder.
You can act on the melatonin-free preference through the included ingredients that made Nightspan appealing to you.
Would three jars be a better way to start than one?
If you want three jars, the planned $165 package is $102 less than three planned $89 single-jar purchases. If you want one jar, choosing the package asks for $76 more upfront. Both comparisons matter: the package lowers the cost of buying three while increasing the first purchase over buying one.
One jar gives a smaller initial order. Three give more supply in one transaction. Neither quantity establishes a duration of use, a clinical trial length, or a better chance of a promised result. Final serving information is not being converted into a time claim here.
Choose the formula first. When you know you want it, the package comparison becomes a practical decision about quantity and cost rather than a way of resolving uncertainty about the product itself.
Does a package choice automatically start a subscription?
No. The one-time single jar and one-time three-jar package do not renew. Replenishment is a separate proposed purchase mode with its own billing and delivery arrangement. Selecting a preference during this preview creates no subscription or payment.
The proposed single-jar recurring price and cadence are stated as planned. A three-jar subscription has separate unapproved terms. It cannot be assumed to use the one-time multipack price or the single-jar replenishment schedule.
Before enrollment, the recurring total, frequency, and cancellation information need to be clear beside the choice. A person who wants to decide about every future purchase can choose one-time purchasing when it becomes available. A person who prefers an agreed repeat order can evaluate replenishment on its actual terms.
What about preparation, serving count, delivery, and returns?
Final preparation directions, serving information, and suitability details will come with the approved label. This page does not assign a drink recipe, a dosing time, or a number of days to the jar. The working active amounts explain the formula; they are not instructions for use.
The completed offer also needs its final all-in charges, delivery information, and return eligibility. Those facts should be available before you pay. An eventual returns policy is a commercial arrangement, not proof that an ingredient study predicts your experience.
The useful decision now is whether Nightspan and a particular package appeal to you. Its ingredient reasons and the price comparison give that choice substance. The final label and terms will complete the purchase information.
Make room for an evening powder you have a reason to want
Imagine an ordinary evening at home. The work is put away. A book or a conversation has some of your time again. Among the things you have chosen for yourself is a powder whose ingredients drew more than a passing glance.
You remember why this powder earned the space. The 3 g glycine foundation connected with your interest in sleeping better. You wanted the magnesium form, free-form theanine, and planned standardized saffron beside it, with supporting zinc accounted for. The complete selection appealed more than arranging each ingredient separately.
That is a concrete reason to make room for Nightspan. The evening remains yours to shape; the product is one deliberate choice within it. Its melatonin-free composition respects the preference you began with, while its included actives give the jar its own identity.
Now match the order to your preference. One planned $89 jar keeps the first one-time purchase smaller. Three planned jars for $165 put more on hand at $55 per jar, without automatic renewal. Proposed $55 single-jar replenishment every 30 days is a separate recurring arrangement; final terms remain pending.
The formula you have explored is the formula behind each option. Bring those ingredient reasons to the package selection and choose the order that fits.
