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.

Perfectly Balanced
It works perfectly! I took it around 1030pm. Roughly 2hrs after eating. I shot straight up at 6am ready to rock and roll! Didn't even need the alarm. Then I had steady energy the rest of the day. No crash. 100% recommend

This Actually Replaced My Morning Caffeine Hack
I don’t write reviews often, but this earned one.
I’ve spent years trying to hack mornings. Energy mints. Leaving a Ghost on my nightstand so I could slam it the second I woke up. I’d literally drink it and then fall back asleep until the caffeine hit.
Zest is the first thing that’s actually made me stop doing that.
I still have mornings where I crawl back into bed for a few minutes because, well…I’m human. But getting up is noticeably easier, and I don’t feel like I need to shotgun caffeine just to start my day.
It’s one of the few products where I genuinely notice when I’m taking it versus when I’m not.
Great product. Great team. Easy 5 stars

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!

Works like a charm!
I bought these for my boyfriend because he’s been feeling sluggish and exhausted when he gets up for work. He says there’s a noticeable difference when he takes them and waking up is a lot easier. He feels more energized throughout the day than he used to, and he doesn’t experience a crash when they wear off.

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.)

I can’t believe how…
I can’t believe how well this works and how it has changed my life! I’m serious, I would wake up in such a funk and felt horrible. I couldn’t think straight, I felt hungover, I was irritable, and I just couldn’t wake up and get going. I was always waking up from either a deep sleep or REM sleep. I read about how this works, the science, and it really makes sense and obviously works. I wake up feeling normal, like I’m supposed to, and even better with some actual energy and cognition! I don’t dread waking up anymore at 6:30 for work. I can actually use my mornings for things I want to do instead of sitting there like a zombie. Real customer here, not paid, and definitely recommend!

A noticeable difference!
I 100% notice a difference in my morning energy when I do take it. However, sometimes I still sleep in, despite taking two pills. Definitely try to take it on an empty stomach, as I notice that it’s more effective that way.

30 days in, and I’m waking up ready—Zest Wake‑Up Pill is delivering
I've been using the Zest Wake‑Up Pill for about 30 days—and it works exactly as promised.
Take one capsule before bed (preferably on an empty stomach), and around 7–8 hours later, the caffeine releases—right when you’re waking up. No groggy snooze cycles. Just clean energy delivered at the perfect time
