Worked as advertised, but word of warning!!
If you take any SSRI medication, taking L-Theanine as well may increase your risk of seratonin syndrome, a rare but extremely serious condition. If you take any serotinergic medication like SSRIs (Lexapro, Prozac, etc.), MAOIs, or TCAs, make sure you understand the risk and know the symptoms of seratonin syndrome when taking any supplement with L-Theanine.
A lot of people taking SSRI's have trouble waking in the morning and would benefit immensely from this product, so I hope Zest Labs releases a secondary version without L-Theanine so we can feel safe and comfortable taking it every day. At the moment I am only taking one pill (40mg caffeine, 40 mg L-Theanine) out of caution, but I wish I could take a full 80mg caffeine.

“Waking up after 7 hours like clockwork”
From Day 1, Zest has consistently worked in 7 hours for me. I'm still figuring out the timing and if I want to be a morning exerciser before getting ready for work, but I'm waking up less groggy and more able to plan and make decisions. I used to wake up well before I needed to be up in order to have multiple alarms and a slow morning to let the coffee hit. Taking Zest is already a big improvement for a night owl with an early morning job. My only issue is sometimes I want more than 7 hours of sleep, but it will wake me up after 7 hours. So it's hard to take daily, though I know that is how it works best. I'm going to try to take it at 10PM even on weekends to wake up at 5AM and hope those habits become regular during the workweek. I've been waking up a few minutes before my alarm every day, so it's not a surprise.

“Got me off provigil”
so I have idiopathic hypersomnia, and it has been getting increasingly worse in the last year. I was taking Provigil 200 mg twice a day and I was still having issues staying awake. Unfortunately, the Provigil put me in afib so taking more wasn’t really an option. My provider found this for me, and I started taking it in place of the provigil. It was a rough transition at first because I was also on propranolol. But after about a week, it helped me tremendously. Now I take two of these at night and I actually feel awake enough to drive to work. It’s safer because I don’t go into AFib anymore.

Clever and Legit
This is has actually been a game-changer for me. I’m a coffee addict and the time between waking up and getting caffeine into my system is pretty miserable. This totally eliminates that and I’m drinking much less coffee overall. I also have a lot of anxiety about sleeping through alarms when I have something important. Taking these little puppies before bed is such peace of mind that by the time my alarm comes around, I will either already be awake, or have no problem waking up to it.

Zest is a total morning hack
I was skeptical about taking caffeine before bed, but the timed-release thing actually works the way they say it does. I’ve been on Zest for over a month now, and I’m waking up at a regular time on my own — and, the part I care most about, without the heavy grogginess I used to have. I used to need a solid 45 minutes and a coffee before I felt like a functioning person. Now I’m clear-headed pretty much from the moment I’m up.
The routine couldn’t be simpler: two capsules with a little water before bed, don’t chew them, done. My sleep itself hasn’t felt disrupted, and I haven’t had jitters or an afternoon crash.
If mornings are the part of your day you dread, this is worth trying.

Wow - they actually work!
I have only been taking this for about a week, but it's a game-changer! I take two capsules around 10pm, and when my alarm goes off at 6am I am able to get right up without the usual stumbling to the kitchen for a coffee or energy drink. I'm really impressed as how much less painful my mornings have been this week.

I don't write reviews.
Ok. First things first, I don't write reviews. This might be my first real review ever. But I want people to hear this. I've had an interesting journey with Zest. It started off poorly, waiting a month plus to receive my order which I was extremely excited for (with what I would consider insufficient communication about the delay, though it was around the holidays). When it finally came, my first night trying it I didn't really feel much. Some context: I am a daily caffeine drinker (1-3 cups per AM). I've been drinking coffee for decades so I believe I've built up a bit of a tolerance. After some research, I decided to up my dosage to three pills per night. That was it. Perfect. I suffer from sleep inertia in a big way. I've been working on a solution for years. I have sleep apnea and have been using a CPAP for three years. I thought that might cure me of waking up feeling like a lesser primate. But alas, no. That was not it. I definitely felt better throughout the day having slept more soundly with fewer wake ups overnight, but I still needed 1-2 hours in the morning to feel like myself. With three Zest pills prior to bedtime (11pm is when I take it), when my alarm goes off or my child crawls into bed and my eyes open, I am ... awake. Fully awake. Joyfully and excitedly awake. Cons: it's expensive and there are other delayed release caffeine pills out there. But the reason I decided to reup for another 3 month supply (which will admittedly not even last me three months as I am taking 3 pills instead of 2) is because of the addition of L-Theanine and B vitamins into the mix, plus the very tight window where the caffeine is released. Cheaper caffeine pills can not promise the same delayed release schedule. Ok Ted talk over. Get zest. You won't regret it.

More, better, constant energy
I feel so much more energy now throughout the day! And it's not in peaks like with coffee, it's constant instead. It's also got rid of my grogginess when I wake up, which feels really good. Definitely recommend!

I was skeptical
I'm naturally skeptical but an avid believer in science. So after reading about the development process and the conducted scientific studies, I was on board to try these magical capsules. I was not disappointment, Zest works wonderfully for this mom. I typically take 1 capsule before bed as 2 capsules had me waking up a little too early. The release is smooth, no drop off. I still have my sacred cup of coffee in the late morning or early afternoon but that's because I want it, not because I need it for the caffiene. Also, I have been told that I am more tolerable in the mornings too since starting Zest per my family's review.

Great for Mornings, Even Better for Travel
I’ve been using Zest Wake Up Pills for a while now, and the best way I can describe them is that they make it feel like I’ve already had a cup of coffee before I even leave bed. I’m not suddenly bouncing off the walls, just awake, alert, and much less tempted to hit snooze five more times.
They’ve also been a lifesaver for travel. I go to India fairly often, and jet lag on those trips can be rough, but these have helped tremendously with getting onto a new schedule and feeling functional a lot faster. Anything that helps you remember what day it is after a long-haul flight is doing something right.
One practical note: timing and what you’ve eaten does seem to matter a bit. I’ve noticed they tend to dissolve faster when I’ve eaten junk or a heavier meal, and a bit more slowly when I take them on a lighter stomach, so it’s worth paying attention to what works best for you.
Overall, they’ve become a regular part of my routine both at home and on the road. Simple, effective, and they make mornings feel a little less like a battle. Thank you for making this product!

Gives me an extra 1.5 hour of productivity in the morning!
Definitely helps with more productivity in the morning. Previously, I'd wake up at 7, groggily make my coffee, and be just about functional by about 9:30AM. I now take two tablets of Zest at midnight, wake up at 7, and am ready to hit the ground with work by about 8AM.

Zest = LIFE CHANGING
Zest has been life changing for me. I struggle so badly with waking up in the mornings that I’ve been on seriously thin ice at work. Zest changed that for me. I wake up feeling refreshed, recharged, and ready to go when I take Zest. For me personally I’ve found the best time to take it is at 9:30 PM. Sometimes I even take 3 instead of 2 for that extra boost. Think natures adderall - without the crash. Specifically formulated for morning wake ups. I can still have coffee with my zest and feel fine. Zest does more than just put pep in my step. It allows me to be a better human being. I’m thriving with Zest and highly recommend it to anyone else who struggles with severe morning grogginess and/or sleep disorders!

Surprisingly Effective — A Game Changer for My Mornings
I decided to try Zest Wake Up Pills because I’ve been trying to manage my caffeine intake while pregnant, and I was really hoping to find something that could help me wake up feeling more alert without reaching for coffee first thing in the morning. I wasn’t sure what to expect, but these have genuinely impressed me.
You take two pills before bed, and by the next morning I feel noticeably more refreshed and clear-headed. It’s not a jittery or artificial feeling—just a smoother, more natural start to the day. I love that it helps me feel awake without immediately relying on caffeine.
The product is easy to use, gentle on my system, and the routine fits seamlessly into my nighttime habits. I also appreciate that the company is a startup; the packaging is clean, the instructions are simple, and it feels like a thoughtful, well-designed product.
Overall, I’m really happy I gave these a try. They’ve made my mornings easier, and I feel more in control of my energy levels. Definitely worth considering if you’re looking for an alternative way to support your morning wake-up routine.
(As always, especially during pregnancy, it’s important to check with your doctor about any supplements—but for me, this has been a great addition.)
