Real Benefits. Backed by Research.

Carefully selected ingredients, clearly explained, for a simple daily wellness routine.

Deep, uninterrupted sleep Deep, uninterrupted sleepFall asleep faster. Stay asleep through the night.
Selerb uses the form that actually reaches your nervous system, where it calms the signals that keep your brain wired at night. Most people start falling asleep faster within the first week. By week 2-3, the 3am wake-ups get shorter or stop completely. You sleep through the night — not because you're drugged, but because your body finally has what it needs to rest.
Calm nervous system Calm nervous systemTakes the edge off stress and racing thoughts.
That wired-but-tired feeling — exhausted all day, but the moment your head hits the pillow your brain starts replaying every conversation you had — that's your nervous system stuck in overdrive. Magnesium is the mineral that tells it to slow down. It helps your brain produce GABA, the neurotransmitter that turns off racing thoughts. It lowers cortisol, the stress hormone that keeps you on edge.
No more leg cramps No more leg crampsStops nighttime cramps and calms restless legs.
Most customers report cramps fading within the first week. By week 2, they're usually gone. If you've been dosing up on potassium, drinking pickle juice, or stretching for hours trying to fix this — the real issue is almost always magnesium your body can't use. SPNutrition fixes that.
Wake up clear, not groggy Wake up clear, not groggyRested - not drugged, not foggy
This is where SPNutrition is different from sleep aids. Melatonin leaves most people groggy. Sleeping pills leave you foggy for hours. SPNutrition doesn't knock you out — it restores what your body was missing. You fall asleep naturally, sleep deeper, and wake up feeling like yourself again. Clear head. Steady energy. No hangover.

Great tasting w/ great benefits!

This is packed with amazing ingredients, magnesium glycinate, ashwaganda, L-theanine, and more all in one easy drink mix. I've noticed less body ache and stress since taking it daily. It dissolves well and tastes way better than most magnesium powders I've tried. I also appreciate that it uses magnesium glycinate, which is much gentler on the stomach than citrate. My only downside is the price for the amount you get, but overall, it's a great calming supplement that actually works.

It's an easy, tasty way to help manage stress naturally without feeling drowsy.

I've been looking for something to help me unwind in the evenings, and this has actually become part of my nightly routine. The raspberry lemon flavor is light and pleasant, not too sweet, which I appreciate since it's sugar-free. I can feel a noticeable sense of calm about 30 minutes after drinking it, and it seems to help me focus better when I'm feeling tense or mentally scattered. I like that it combines magnesium with ashwagandha and L-theanine, so it supports both relaxation and mood.

Not a fan of the flavor

This calming drink mix has great ingredients to support mood, nervous system and sleep. Easy to use. The powder dissolves easily. It comes in individual packets that makes it portable. The only issue I have is the taste. There are flavorings and a stevia leaf extract that I could do without. I prefer it to be flavorless instead. Otherwise, this combination does a good job of destressing my system in preparation for bed.

Tasty drink with zero sugar and supports focus

Stress is so much a part of life today and anything to keep me focused and calm is welcome. Apart from the tasty raspberry flavor, it is sugar free and contains ingredients like magnesium glycinate which is known to support calm and focus.

It is easy to use and portable. The package comes with 20 stick packets of powder that easily dissolve into 8-14 oz of water for a refreshing drink.

I love the fact that it is made in the USA. I have been taking this for a few days now, and I have noticed a better and restful sleep. Recommended.

Adds great flavor to water with extra calming benefits

I suffer with major stress and anxiety, including difficulty unwinding and sleeping at night. As such I have started trying a variety of supplements designed to help calm the mind. These flavor packs have an excellent raspberry lemonade flavor that tastes just right in a 20oz of water. It is not overbearing like some are, and the flavor can be subdued even more by mixing in more water or using smaller quantities per serving. I especially like that it uses natural raspberry and lemon flavoring, among other organic ingredients. Very simple ingredient list, with the heavy supplements being 22mg Vitamin B6, 25 mcg Vitamin D3, 350mg L-Theanine, 350mg KSM-66 extract, 150mg magnesium and 150mg lemon balm extract. You can research each of these to review their effectiveness on rest and anxiety, but there is a lot that supports their benefits. You are meant to take two a day, though I find even one in the afternoon-evening is enough to help me feel better through the night.

Good Product

I was looking forward because when nighttime comes, I really need to try and relax. First thing is, why 2 sticks? To me that seemed a little odd. The taste is okay, but they could have just added more magnesium to one stick. The plus side is that it has no sugar, the quality of sleep is better, so the effectiveness it there. Little pricey.

Calming Drink Powder

This Calmtrio powder packs all the right ingredients for calming the mind and the body. I wish, each packet included a bigger amount of Magnesium, it would have increased its effectiveness. It dissolves easily in cold water and tastes great with the right amount of sweetness. I have noticed one small issue with it, if you leave it in the glass for a while then it becomes stale. Therefore, I drink it quickly. I like that it contains no sugar or artificial colors or flavoring, a big plus for me. Overall, a decent supplement with key nutrients for its functionality. At its current sale price (19.99), it is a fair value.

Great products!!????

Works really well, and taste good drink before bed and it calms me down!! ????

Good supplements. Off taste due to artificial sweeteners.

While the taste wasn't bad it did have an off which I would attribute to artificial sweeteners. There is no sugar. The powder mixes easily in cold water.

The product didn't seem to effect my sleep quality but it didn't disturb it either. The supplements it contains should improve sleep if you are deficient in these nutrients.

I find the price a bit high but not out of line.

At Last! A Powdered Drink You Can Take on an Airplane!

Recently, I had a powdered drink in a zip lock bag and TSA had it all over the place, so these individual packets work great.
New flavors often need to grow on you.
In my second trial, I put it into mineral water (San Pellegrino), and it was a lovely nightcap.

Five stars for ingredients, three stars for taste

The ingredients are perfect to relax your system, these are ingredients I have successfully used before. I was interested in a drink that would combine them all for an evening beverage. The color was pretty bold, but that's fine with me. However, I'm sorry to report that I was really disappointed in the taste. I couldn't drink it. They need to put more flavoring in. Right now it's only 5 calories--I'd rather it was a little bit more and tasted a whole lot better.

Calmtrio

I decided to try this as a little sleepy girl mocktail. I like that each serving comes in an individual packet to be mixed with water. I typically don't like overally sweet drinks so I mixed it initially with about 12-14 oz of water. These packs don't really have much flavor to be honest- the drink mostly just tastes a little sweet with a hint of lemon on the back end. The initial powder had a very artificial lemonade scent so I was pleasantly surprised that the taste was not overwhelming
The powder mixed in well without any clumps or a powdery finish
I like that they are very transparent with their ingredients, telling the amounts for the important parts of the drink (as opposed to saying a "propietary blend"); as well as all the ingredients are natural (no artificial eyes)
The recommended serving is 2 sticks per day which I don't love, especially because thats still only 72% of recommended magnesium but over 200 % the vitamin d/b
I did not get any overwhelming sense of calm after taking this, however, I didn't NOT feel calm. So I'm not sure if that was just my normal emotion or if if it did help in some amount that was unnoticeable to me, however, I typically tend to have a higher tolerance for things like this to begin with.

Herbal Lemon - Helpful & Calming

Let's be honest...I've reached a point in my life where I could use a little bit of extra help falling asleep. I've tried all kinds of options, from "recreational" gummies to traditional supplements, even a nightcap or two. But I'm always looking for something that feels different and doesn't leave me feeling groggy, foggy or forgetful the next morning.

That's what I really like about these CalmTrios. It isn't just one ingredient doing the work, it's a carefully curated blend. Magnesium is already helpful on its own, but combined with lemon balm, L-theanine, and ashwagandha, it brings an added layer of relaxation and benefit.

One thing to note: the lemon balm does give it a bit of an herbal flavor. Personally, I found it easier to chug rather than sip slowly, but it wasn't unpleasant just something to be aware of.

The effects came on fairly quickly for me. I felt relaxed and calm without any heavy grogginess, just an overall sense of calm and well-being.

Overall, I really appreciated this product and would recommend it.

It does just what it says and both calms and clears your system. It desolves quickly, and the taste is great. I recommend it 100%

Great Tasting Magnesium Drink Mix

I am usually hesitant to try powders like this because they usually have sugar or sugar replacement.
I was thrilled to find that this Magnesium Glycinate Powder does not have any sugar or sugar substitutes.

I mixed up a pack with 8oz of water, and the powder all dissolved within moments of shaking.
The taste was fantastic! It was more Raspberry forward than Lemonade, which is fine with me.
It was a very mild taste, not punch you in the tastebuds strong, which is also good for me.
There was no gritty aftertaste, and it was very easy to drink.
The packets make it very convenient to toss in my car or my pocket so that I have some available on the go.

I didn't notice any instant effects, but I have a lovely evening after drinking after a stressful day.
Overall, I am very pleased with this drink mix and would recommend to others.

Easy and delicious

I have been trying to increase my magnesium intake and was excited to find this powder. It comes as individual packets inside a large bag, which makes it super convenient and easy to take on the go without needing to measure. The powder mixes smoothly and the flavor is mild, a light raspberry lemonade flavor that isn��t too strong. For the amount you get, it feels like a great value.

Great evening supplement

I like that I can sip on this in the evening while winding down and cleaning up around the house. It tastes good and doesn��t give me any funny burps. I like that there is no melatonin in it.

Calmed the mental chatter

Flavor is mild, I used little water (5oz) as I didn't want to have a full bladder before bed so for me it tasted earthy, I tasted the beets and didn't mind that at all. Another household member mixed it with a full sized glass (12oz) and also said the flavor is very mild. Both of us can report that it relaxed our frenzied minds and we both slept well. And one more household member took it when she was feeling overwhelmed with workload and deadlines, she felt more focused and less hurried after drinking CalmTrio. It gets a thumbs up from our household!

My Secret Weapon for Deep Sleep: CalmTrio Powder

I've added the CalmTrio Magnesium Glycinate Powder to my nightly routine, and it's truly made a fantastic difference for me. I got the Raspberry Lemon flavor, and I have to say, it tastes great.it's actually a pleasure to drink! The convenience is a huge plus because it comes in these nice individual packets that are easy to use. I just mix one packet in water, and it mixes cleanly without any clumps or residue, which makes it an effortless and simple step in winding down before bed.

I can honestly say that this stuff really works. I take it every night, and it helps me immediately feel calmer and more relaxed. The biggest benefit has been the quality of my sleep; I am sleeping deeply throughout the entire night and not waking up constantly. As a result, I wake up the next morning feeling great and genuinely well-rested. If you're looking for an effective, tasty, and easy-to-use supplement to improve your calm and rest, this has been an excellent addition to my life.

Nice blend, tastes good

I was pleasantly surprised at the "drinkability" of this mixture. I'm not usually a fan of powdered drink mixes, but the ingredients in this one were exactly what I was looking for, so I decided to give it a try.

While I won't go so far as to say I thoroughly enjoy it and crave it for the flavor, it is pleasant enough that I don't feel like I have to down it quickly or gag to get it down. For me, that's really saying something :) It tastes a lot like a typical raspberry lemonade beverage should - and without an unpleasant after taste.

This particular blend, also, is extremely good at helping me to unwind at the end of the day and sleep soundly.

Nice drink for bed

This calm trio supplement is so nice to take the anxiety edge off for me. I drank this before bed and I felt so much better. It didn��t knock me out or make me feel weird just a nice calm. It taste pretty good too. Like a raspberry lemonade. It is sugar free made with great ingredients and lab tested. You get a 20 day supply.

CalmTrio Magnesium Glycinate Powder = works for me

CalmTrio Magnesium Glycinate Powder has a nice flavor and is pleasant to drink. I mixed one tube a standard water bottle that was room temperature but it does mix thoroughly in cold water. I have taken all of the ingredients individually with excellent results and I like the convenience of a drink mix. This is nice and calming and I didn't have any stomach issues. I like that this is made in the USA
