    • Magnesium (as Magnesium Glycinate) — 275 mg elemental per serving

    90 capsules per bottle. At two per night, that is 45 nights — not 30. We could round it to a tidier number and quietly hope you did not check. We would rather you checked.

    The complete panel is printed on the bottle and shown in the product photos. No proprietary blends, nothing hidden.

    How to take it

    Two capsules in the evening, with or without food. Most men take it 30 to 60 minutes before bed.

    This is our bigger bottle — 90 capsules, which at two a night is 45 nights rather than the usual 30. That works out at about 89 cents a night.

    What does this do

    One mineral, taken in the evening, that supports normal sleep quality and muscle relaxation.*

    275 mg of elemental magnesium per serving, in the glycinate form. Elemental is the figure that matters — it is the magnesium itself, not the weight of the whole compound, and that distinction is most of the product. Glycinate rather than oxide, which is well absorbed and gentle on the stomach. Magnesium is involved in over 300 processes in the body, including muscle and nerve function.

    What it is not: it is not a sleeping pill and it will not knock you out. It supports the systems your body already uses to wind down. If you have a diagnosed sleep issue, that is a doctor conversation.

    Worth knowing before you buy. A small number of people find glycine stimulating rather than settling, and sleep worse on it. It is not common, but it is real, and we would rather you heard it from us than found out at 2am.

    Magnesium can affect absorption of certain medications, including some antibiotics. Space it out and ask your pharmacist — they answer this one all day. If you have kidney disease, ask your doctor first.

    How to tell if it's working

    Note how long it takes you to fall asleep, across seven nights, before you start. Write it down.

    Check again at week four — that is your refund decision, because the guarantee closes at day 30.

    Then check again at week eight. That is the fuller answer, and it lands after the window has closed. Both numbers are yours, not ours.

    The guarantee, and how it actually works

    30 days from delivery. Here is the machinery.

    One message through the Contact page with your order number. That's the whole process.

    No form. No photo. No reason required. No return shipping, no restocking fee. No retention call — there's no script, because we never wrote one.

    Empty bottles are honored. Refund to your original payment method, usually two to five business days after we confirm.

    What's inside

    One mineral. The form and the elemental dose, both on the label.

    Magnesium (as Magnesium Glycinate)275 mg elemental

    Magnesium bound to glycine, an amino acid. The form matters for two reasons: it is one of the more absorbable ones, and it is gentle on the stomach. The cheap stuff — magnesium oxide — is poorly absorbed and famously sends people sprinting to the bathroom. We skipped it.

    And the number matters more than the form. Magnesium is always bound to something, and glycinate is roughly 14% magnesium by weight, so 275 mg of elemental magnesium takes about 2 grams of the compound. Cheaper brands print the compound weight and let you assume it is the elemental weight. That is a six-to-sevenfold difference in the thing that actually does the work.*

    What it supports

    One mineral. Four things it supports.

    Supports normal sleep quality

    Most men take it 30 to 60 minutes before bed. Hence the name.

    Supports muscle relaxation

    Magnesium is involved in over 300 processes, including muscle and nerve function.

    Gentle on the stomach

    Glycinate, not oxide. Well absorbed, and it stays where you put it.

    Supports healthy magnesium levels

    Most men's diets fall short of the recommended intake. This is a gap-filler, not an exotic addition.

    What to expect

    This takes time. Here is roughly how long.

    Magnesium is a mineral, not a sedative. It supports the systems your body already uses to wind down — which for some people is noticeable inside a fortnight and for others is never obvious at all.

    2. Weeks 2–3

      Calmer evenings

      Some men report this early, and it is the most common thing they report. Some report nothing.

    3. Day 30

      The decision point

      The guarantee closes here — and you are only two thirds of the way through the bottle, because it holds 45 nights.

    4. Days 30–60

      The fuller picture

      If levels were low, this is where it settles. That lands after the refund window. We would rather say so than round the numbers together.

    1. Nicholas P.

      Exactly what I ordered

      Arrived as expected and the capsules are easy to take. I wanted magnesium glycinate and that's what I got.
    2. Ethan J.

      Exactly what I wanted

      I wanted something simple to add to my nighttime routine. REST does exactly that. No powder, no weird flavor, just capsules.
    3. Christopher L.

      The simplicity sold me

      I've bought too many supplements where the front of the bottle makes ten different promises. REST is much more straightforward, which I actually prefer.
    4. Caleb M.

      Pretty straightforward

      Pretty straightforward magnesium supplement. I specifically wanted glycinate and liked that the label was easy to understand.
    5. Zachary F.

      No unnecessary complexity

      Some supplement formulas seem like they're trying to win an ingredient-count competition. I much prefer this approach.
    6. Daniel T.

      Simple and easy

      Simple, clean, and easy to take. That's what I wanted.
    7. Patrick N.

      The supplement I actually remember taking

      Sometimes the best supplement is the one you actually remember to take. REST has been that for me.
    8. Ryan T.

      I like the magnesium choice

      I specifically wanted magnesium glycinate and found the formula here pretty straightforward. That's what made me give it a try.
    9. Thomas K.

      Good quality feel

      The bottle and packaging feel much nicer than the generic supplements I've bought in the past. The formula is simple too.
    10. Marcus R.

      A nighttime routine I can stick with

      I've tried a few different magnesium products and most of them either upset my stomach or were just another bottle sitting in the cabinet. REST has been easy to make part of my nighttime routine. I take it after dinner and that's about it. The biggest thing I've noticed is that I don't feel like I'm carrying the whole day into bed with me.
    11. Chris D.

      Actually stuck with it

      Three weeks in and I'm keeping it in the cabinet. That's saying something because I usually quit supplements after a week.
    12. Joshua N.

      Good for travel

      I've been traveling more lately and this is much easier to pack than a tub of powder. Small bottle, capsules, done.
    13. Nathan V.

      Has become part of my routine

      I started taking REST after realizing I was terrible about having any sort of consistent nighttime routine. I'm not going to say a supplement magically fixed everything, because it didn't. But taking REST has become the signal for me that it's time to stop working and wind down. I like that.
    14. Brandon K.

      Fits right into my evening

      I keep REST beside my bathroom sink, so I see it every night. It's one of those little habits that's become automatic.
    15. Jason K.

      No powders or complicated routine

      Exactly what I was looking for. No giant scoop, no drink mix, just capsules.
    16. Daniel V.

      I wanted glycinate

      I had already decided I wanted magnesium glycinate before I started shopping. REST was one of the cleaner formulas I came across.
    17. Kevin B.

      No weird aftertaste

      Good addition to my evening routine. No weird taste or aftertaste.
    18. Jeffrey T.

      Easy capsules

      Nothing to mix and nothing to measure. That's exactly what I wanted.
    19. Derek A.

      Easy to take

      Easy to take and doesn't have that gross vitamin smell some bottles have.
    20. Jason M.

      No giant ingredient list

      One thing I liked immediately was the fact that I could understand the label. There isn't a massive list of ingredients competing for attention.
    21. Anthony J.

      Very straightforward

      There's something nice about a supplement where you don't need to study the label for ten minutes. REST is very straightforward.
    22. James W.

      A simple addition to my evenings

      I wasn't expecting anything dramatic, which is probably why I ended up liking it. I take two capsules as part of my evening routine and after a few weeks I realized I was actually looking forward to shutting everything down at night instead of staying on my phone until midnight. Can't say the supplement did all of that by itself, but REST has become part of the routine.
    23. Tyler R.

      Much easier than powders

      I've bought magnesium powder before and eventually stopped using it because I got tired of mixing it. Capsules work much better for me.
    24. William B.

      I did my homework

      I compared several magnesium products before choosing REST. The form of magnesium, straightforward labeling and lack of unnecessary extras were what stood out to me.
    25. Brian E.

      A convenient option

      I prefer capsules over drinks and powders, so this checked that box immediately.
    26. Brandon C.

      Good formula

      I've compared quite a few magnesium products and liked the ingredient profile here. I've been taking it consistently for a few weeks.
    27. Thomas H.

      Exactly the kind of supplement I wanted

      I've never been the guy with a 12 step supplement routine. I wanted one or two things that made sense and REST was an easy choice. The capsules are straightforward and I like that magnesium glycinate was specifically listed rather than just magnesium.
    28. Andrew C.

      Clean and uncomplicated

      Clean-looking bottle, simple formula and easy capsules. I don't need anything more complicated than that.
    29. Gregory M.

      Finally keeping it simple

      I used to have a ridiculous supplement routine. Different powders, different times, different bottles. I've cut most of that out and REST is one of the few things I've kept.
    30. Steven A.

      Fits my evening habits

      I've been trying to make my evenings less chaotic. Having a consistent supplement routine is a small part of that, and REST has been easy to keep up with.
    31. Justin F.

      Finally found one I remember

      My biggest problem with supplements is remembering to take them. Keeping REST on my nightstand has actually helped.
    32. Stephen R.

      Convenient every night

      I leave the bottle in the same place and take it every evening. Very little effort involved.
    33. Adam R.

      No flavor to deal with

      This is one of those situations where capsules are better. I don't want my magnesium tasting like something I'm supposed to enjoy.
    34. Robert M.

      I liked knowing exactly what I was taking

      Magnesium glycinate was recommended to me by a friend. I liked that REST actually tells you how much elemental magnesium you're getting instead of hiding behind a giant proprietary blend. That transparency was probably what convinced me to try it.
    35. Michael D.

      I appreciate the transparency

      I've become much more particular about supplements. I want to know the actual form of an ingredient rather than just seeing a generic name on the front of the bottle. The magnesium glycinate was a big selling point for me.
    36. Aaron L.

      No unnecessary ingredients

      I appreciate that this isn't loaded with 15 different ingredients. Magnesium glycinate, clear label, simple bottle. That's what I was looking for.
    37. Patrick C.

      Thoughtful formula

      I like that the formula is centered around magnesium instead of trying to turn itself into a full multivitamin. It feels intentional.
    38. Justin W.

      One bottle instead of several

      I was looking for magnesium without adding another complicated supplement stack. REST keeps things simple.
    39. Benjamin C.

      I like the overall approach

      The product feels intentionally designed rather than overloaded. Magnesium is the focus, the directions are simple and the bottle doesn't make a bunch of outrageous promises.
    40. Jonathan M.

      Simple enough for me to stick with

      I've always struggled with routines that have too many steps. REST takes almost no effort, which is probably why I've been able to stay consistent with it.
    41. Tyler B.

      Solid

      Solid magnesium supplement. Nothing complicated about it.
    42. Eric F.

      Good everyday option

      Good option for anyone who wants a basic magnesium supplement without a lot of extra ingredients.
    43. Matthew G.

      Much easier than powdered magnesium

      Easy to take and easy to remember. I've been much more consistent with this than powdered magnesium products I've bought before.
    44. Charles N.

      Makes sense in my routine

      I'm trying to be more consistent with the basics—food, exercise, hydration and getting enough downtime. REST fits into that without requiring much thought.
    45. Steven D.

      The label convinced me

      Bought it after comparing several magnesium products. The elemental magnesium number being clearly stated was a big plus for me.
    46. Cameron D.

      The label is actually readable

      Small thing, but I appreciate a label that isn't covered in marketing language. I can quickly see what I'm taking and move on with my day.
    47. Edward J.

      Exactly my kind of supplement

      Simple ingredients, easy capsules and a clear purpose. That's basically my checklist for a supplement, and REST hits all three.
    48. Nathan S.

      Easy to remember

      I take REST after I brush my teeth. Tying it to something I already do has made it really easy to remember.
    49. Cameron R.

      I like the evening routine

      I bought this mostly because I wanted to get more disciplined about my evenings. I take REST after dinner, put my phone away and try to actually relax for a little while. It's become one of those small habits that I don't really think about anymore.
    50. Dylan S.

      Much better than powder

      I've tried magnesium powder before and just got tired of mixing it every night. Capsules are way more convenient for me.

    Questions

    Questions men actually ask.

    Including the awkward ones. If yours is not here, ask us on the Contact page and we will answer it plainly or tell you we don't know.

    Why glycinate and not the cheaper forms?

    Absorption and stomach comfort. Oxide is cheap because it mostly passes through you. Citrate is decent but can loosen things up. Glycinate is what you pay a couple of dollars more for and then never think about again.

    What does “275 mg elemental” actually mean?

    Magnesium is always bound to something, and what it is bound to changes the number on the label. Glycinate is roughly 14% magnesium by weight, so 275 mg of elemental magnesium takes about 2 grams of the compound.

    Cheaper brands print the compound weight and let you assume it is the elemental weight. That is a six-to-sevenfold overstatement of the thing that does the work. We print the elemental figure and name the form, because those are the two numbers you would need to compare us against anyone else.

    How many nights is a bottle?

    Forty-five, not thirty. Ninety capsules at two a night. About 89 cents a night.

    We could have called it a one-month supply and hoped you did not do the arithmetic. We would rather you did it.

    Will it interact with my medications?

    Magnesium can affect absorption of certain medications — some antibiotics, for example. Space it out and ask your pharmacist; they answer this one all day.

    If you have kidney disease, ask your doctor before starting. Impaired kidneys do not clear excess magnesium well.

    Is there a subscription?

    Yes, and it's opt-in. This page defaults to a one-time purchase — if you want Subscribe & Save you have to choose it. 25% off, shipped monthly, cancel any time from your account or by messaging us.

    What if it doesn't work for me?

    You message us and get your money back. 30 days from delivery, empty bottle honored, no form and no return shipping.

    Worth knowing: a bottle is 45 nights, so at day 30 you will still have a third of it left. The guarantee honors an empty bottle and a two-thirds-empty one just the same.
