A little care at the start of the day. An evening you look forward to.
You would like to feel comfortable in your skin as you head into the day. And when the evening comes, you would like to put the day down and look forward to bed. Those can both matter to you without being the same wish.
Essentials brings collagen peptides, hyaluronic acid, lutein, zeaxanthin and vitamin C together for you. Nightspan brings the glycine, magnesium, theanine, saffron and zinc together. The pair lets you explore both complete formulas from the start.
One of each is an easy quantity to begin with. You can make room for both now and decide about larger orders later.
One for the care you take with your skin.
Collagen may already be part of the way you care for your skin. Or you may be deciding about your first powder. Essentials lets that choice include more than collagen alone.
It starts with 10 grams of hydrolyzed collagen peptides, Types I and III. Hyaluronic acid, lutein, zeaxanthin and vitamin C come with them.
The collagen research examines skin moisture and elasticity. Hydration concerns moisture; elasticity concerns how skin responds to stretching. Those measures give researchers a way to investigate changes in the skin after people take a collagen preparation.
A 2023 review brought together 26 randomized trials involving 1,721 people. Its pooled findings favored hydrolyzed collagen over placebo for skin hydration and elasticity. The trials used different preparations and doses; a 2025 review found no significant benefits in its high-quality or non-pharmaceutical-funded subgroups. These reviews give the ingredient findings their scope and context. 2023 collagen review, 2025 collagen review.
Hyaluronic acid is included at 200 mg active content as fermentation-derived sodium hyaluronate. Research has studied specific oral preparations for skin hydration and joint symptoms; those findings do not establish effects for this finished formula. The material profile, including supplier assay, purity and molecular-weight specification, is still pending. HA skin study, HA joint study.
Essentials contains 10 mg lutein and 2 mg total zeaxanthin isomers. A small, commercially supported study reported improvements in skin measures, with the combined oral and topical approach producing the strongest overall results. Its oral preparation supplied 10 mg lutein with 0.6 mg zeaxanthin as an oil-based softgel, so it differs from this formula. Lutein and zeaxanthin study.
Vitamin C has an established nutritional role: your body needs it for normal collagen production†. Essentials includes 500 mg actual vitamin C beside the collagen peptides and carotenoids. NIH vitamin C information.
Ten grams of collagen, with the additions already in the bag.
| Essentials active | Amount | Form |
|---|---|---|
| Hydrolyzed collagen peptides | 10,000 mg | Types I & III |
| Hyaluronic acid | 200 mg active content | Fermentation-derived sodium hyaluronate |
| Lutein | 10 mg active | Final powder grade pending |
| Total zeaxanthin isomers | 2 mg active total | RR-zeaxanthin + meso-zeaxanthin; split and grade pending |
| Vitamin C | 500 mg actual vitamin C | Enhanced-bioavailability powder selection; supplier and grade pending |
Astaxanthin is not part of current Essentials. These are locked active amounts; final Supplement Facts, qualified materials and use directions remain pending.
Perhaps hyaluronic acid, lutein or zeaxanthin caught your attention after you chose your present collagen. Their declared amounts are listed alongside the full collagen serving.
Each 30-serving bag of Essentials brings those additions together with the full 10 grams of collagen peptides, with every active amount stated separately.
That is the concrete choice in Essentials: hyaluronic acid, lutein, zeaxanthin and vitamin C alongside the full collagen serving, each with its own declared amount.
The amounts stay fixed together, so increasing the powder would increase every active. Follow the product's directions rather than adjusting the serving to get more of one ingredient. If you need control over individual amounts, separate products give you that flexibility.
Essentials is not vegan; its collagen is animal-derived. Check the complete allergen and cross-contact information, and keep your usual sun protection in place. This powder does not replace sunscreen.
You can read the complete Essentials offer for the fuller ingredient explanation and individual purchase options. The pair contains one 30-serving bag of that same formula. Essentials ingredients and research.
The second bag begins with something quite different: the night you would like to have, and the day you hope will follow it.
One for the night you would like to have.
You finally get into bed. Then remember the thing you did not finish. Check the time. Start working out how much sleep is still possible before the alarm.
It is frustrating because tomorrow will arrive either way. The things you need to do will still be there. So will the things you wanted to do, if you have something left for them.
You would like a better night for more than the hours you spend in bed. You would like to be interested in the conversation. To look forward to a plan that is yours. To reach the end of the day without feeling that the obligations took everything.
Nightspan is the evening powder in this pair. Its starting ingredient has been studied for the night itself and the day that followed.
Three grams of glycine, with a study that looked beyond bedtime.
In a small study of people dissatisfied with their sleep, researchers tested 3 grams of glycine before bed. Participants reported better sleep quality, and measurements showed faster sleep onset. Daytime sleepiness and performance on a memory-recognition task also favored glycine. The pattern of sleep stages did not change. Read the glycine study.
This small, short trial studied glycine. Several authors were affiliated with an amino-acid manufacturer; the next-day performance result concerns the measured memory-recognition task.
A separate 2012 study examined 3 grams during short-term sleep restriction. Seven healthy men were analyzed: fatigue improved on day one, not day three, while reaction times on a sustained-attention test improved on both measured days. Participants and several authors were affiliated with Ajinomoto. These early findings concern glycine alone. Read the next-day study.
Nightspan contains 3,000 mg of free-form glycine per serving—the full 3 grams used in that study. It is a separate ingredient, alongside the magnesium, theanine, saffron and zinc.
That separate amount matters if magnesium bisglycinate is a name you already know. Magnesium bisglycinate includes glycine bound to the mineral. Nightspan's stated 3 grams of free-form glycine are additional to that ingredient, not a number inferred from its name.
Magnesium and theanine come with the glycine.
Maybe your search started with magnesium. Then you read about glycine, and wondered where that left the ingredient you had been considering first.
Nightspan includes both. The full 3 grams of free-form glycine remain in place with 250 mg of elemental magnesium and 200 mg of L-theanine beside them. Each has its own declared amount; the additions do not stand in for part of the glycine.
A four-week study of 155 adults with poor sleep tested magnesium bisglycinate supplying 250 mg of elemental magnesium daily. It found a small improvement in insomnia-symptom scores compared with placebo; other questionnaire results did not differ significantly. The tested supplement also supplied glycine, so the findings concern that combined intervention. Magnesium study.
Nightspan supplies 250 mg of elemental magnesium as fully reacted bisglycinate. Magnesium also supports normal muscle and nerve function†. NIH magnesium information.
L-theanine has been examined in sleep research, too. A 2025 review covered 19 articles and 897 participants, with 18 articles pooled in meta-analyses. Selected self-rated sleep-quality, sleep-onset and daytime-functioning measures improved across theanine-containing interventions. Preparations varied and some combined ingredients; pooled objective sleep measures did not improve significantly. L-theanine review.
Nightspan contains 200 mg of free-form L-theanine, bringing this amino acid into the same evening powder as glycine and magnesium.
You care about how the night felt, too.
Getting into bed is one part of the evening. Waking up pleased with the sleep you had is another.
In a 28-day study of 120 adults with unsatisfactory sleep, the standardized saffron extract used in Nightspan improved sleep-quality ratings compared with placebo. Researchers tested 14 mg and 28 mg, with similar improvements at either amount. Several other measures did not differ between groups. The study was funded by the extract manufacturer. Saffron study.
Nightspan contains 28 mg of saffron extract, standardized to at least 3.5% Lepticrosalides. It is the botanical component of the formula, with the extract research described above.
Zinc completes the active formula. Each serving supplies 15 mg of elemental zinc as bisglycinate. Zinc supports normal immune function and protein production†, an established nutritional role alongside the ingredients selected with sleep research in mind. NIH zinc information.
The complete evening formula in your Nightspan bag.
| Nightspan active | Amount per serving | Form |
|---|---|---|
| Glycine | 3,000 mg | Free-form |
| Magnesium | 250 mg elemental | Fully reacted bisglycinate |
| L-theanine | 200 mg | Free-form |
| Saffron extract | 28 mg | Standardized to at least 3.5% Lepticrosalides |
| Zinc | 15 mg elemental | Bisglycinate |
Nightspan contains no melatonin. If you have been looking for an evening powder without it, this formula brings glycine, magnesium, theanine, saffron and zinc together, with every active amount disclosed.
You can read the full Nightspan offer for more about the research and its individual packages. The AM/PM pair includes one 30-serving bag of this same evening formula. Nightspan ingredients and research.
The formulas you came to consider, kept in their own bags.
Keep the Essentials bag with the things you reach for during the day. Find a place for Nightspan in the evening you look forward to. Two familiar moments become places to begin.
The powders stay separate, so each has its own place in your routine. Follow each product's preparation and serving directions; the AM/PM name does not prescribe a dosing schedule.
Make room for both without overlooking what is already there.
Your multivitamin may already supply vitamin C, magnesium or zinc. A separate carotenoid supplement may contain lutein and zeaxanthin. Those ingredients are also included across Essentials and Nightspan, so the intake from products you keep taking comes together.
An ingredient in the pair does not automatically replace every separate product that contains it. That product may have other ingredients or amounts you need to retain, especially if you take it on professional advice. A clinician or pharmacist can review the complete labels with you before changes involving medicines, medical conditions or overlapping intake.
Use appropriate clinical guidance for pregnancy, breastfeeding or medical conditions. Nightspan is not for children, and kidney conditions require particular care when considering supplemental magnesium.
Both powders have fixed formulas. You cannot leave out one active while keeping the rest of a serving unchanged. Follow each product's directions rather than changing the powder amount to adjust one ingredient.
One Essentials. One Nightspan. The whole package.
| Your AM/PM package | Included |
|---|---|
| Collagen Essentials | One 30-serving bag |
| Nightspan | One 30-serving bag |
Two complete formulas. A one-month supply of Essentials and a one-month supply of Nightspan. One 30-serving bag of each, with nothing else to assemble.
Begin with both formulas you came to explore, at a smaller starting quantity than a three- or six-bag stock-up order of either.
Follow each product's own preparation and serving directions. Find out where each fits in your day before choosing a larger supply. You can replenish either product independently.
The pair price is awaiting approval. The equivalent separate one-time order currently has a $126 product subtotal: $53 for one Essentials and $73 for one Nightspan. That is a comparison basis, not the pair's price or an established saving. If the pair is priced below the separate subtotal, compare the same two bags and the same one-time terms before treating the difference as a saving.
The approved pair price and complete terms will be published before purchasing opens.
Package price: awaiting approval. One-time purchase and subscription options are under review; package shipping, delivery and returns terms remain pending. Purchases are not open.
Start with one of each. Plan another delivery when you want one.
Your first order can be about getting to know the formulas. Replenishment is a decision you can make with that experience behind you.
A one-time purchase would have no automatic renewal. A subscription would have its own price, delivery interval and cancellation terms. The pair's recurring price and schedule are still awaiting approval.
Selecting a preview option creates no order, payment, reservation or subscription. Any future enrollment requires your explicit choice after the full terms are published.
A few things you may still be wondering.
Can I choose only one formula?
Yes. You can explore Essentials on its own or read the Nightspan offer. Each has its own complete composition and individual purchase options.
Each individual bag contains the same complete formula included in the pair.
Does using both produce a greater benefit?
The research described on this page concerns ingredients and study preparations, rather than trials of the finished Dayspan powders or the pair. It does not establish an extra skin or sleep benefit from using both. Choose the pair when you want both complete formulas; either product can also be considered on its own.
Does the collagen count as the glycine in Nightspan?
No. Collagen contains glycine within its protein structure, while Nightspan's 3 grams are a separate free-form glycine ingredient. The full weight of collagen is not a measurement of free-form glycine.
Nightspan's separately declared 3,000 mg identifies its free-form glycine amount. The collagen weight and magnesium amount cannot be added to it to calculate a total free-form glycine dose.
Will both bags run out together?
The pair gives you a 1-month supply of Essentials and a 1-month supply of Nightspan. Follow each product's own preparation and serving directions.
You can decide about later orders separately. The one-of-each package does not require you to keep buying both at the same time.
Is the pair a discount on buying separately?
No pair saving is established while its price remains unapproved. The $126 figure above is the current subtotal for one of each bought separately on a one-time basis.
A subscription price for one product, or a per-bag price that requires buying several bags, is not the price of this one-of-each package. The full pair terms are needed before a like-for-like saving can be calculated.
Can I place the order now?
Not yet. This is a prelaunch preview. You can review the formulas and package options; selecting one does not create an order, charge or stock reservation.
Purchasing and subscription enrollment remain closed. The full approved price, applicable shipping and returns information must be available before an order can proceed.
One for your skin-care routine. One for your evening.
You have seen what is in each formula. You know why the collagen comes with carotenoids, and why Nightspan starts with the full 3 grams of free-form glycine. Now picture where you would keep them.
Essentials beside the things you reach for during the day. Nightspan ready for the evening you have been looking forward to. One 30-serving bag of each to start, with the size of any future order left to you.
Choose both complete formulas: one Collagen Essentials bag and one Nightspan bag.
Package price awaiting approval; purchases are not open.
