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

No more sleeping through alarms
I'm a very deep sleeper and am slow to wake up, even after getting plenty of sleep. I've missed plenty of alarms and overslept, and the first hour or more of the day has always been wasted in a mental fog. Zest has made an incredible difference in my morning routine. Now when the alarm goes off it's like my mental gears are already turning, which makes it so much easier to take the first step of simply getting out of bed. The time-delayed release works very well; I haven't noticed any effects before bedtime, even if I stay up for a bit after taking Zest. It also doesn't seem to prevent me from getting deep, restful sleep. The recommended dosage of two capsules sometimes leaves me feel a little jittery shortly upon waking, so I started taking one capsule instead, which has turned out to be the sweet spot. For me it's worth every cent and then some.

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.

The solution to morning grogginess!
Just the right amount of caffeine and l-theanine for energy to wake up without worrying about a crash later. No more negotiating with the snooze button in the morning - I just wake up every morning feeling great!

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.)

Game changer
Zest has been a total game changer for me. I take it before bed, and I actually wake up feeling alert (sometimes even before my alarm) which I love. No grogginess, no jitters, just clean, steady energy that makes mornings effortless.

Someone wake up Green Day
Novel approach to a common problem. Delayed release caffeine has been a game changer for me. I've gotten a night time centric rhythm thats caused me to be very groggy and sleep in during the mornings, though this isn't conducive to my job. Zest gives me a boost for the morning and with their new version including L-theanine, fights off jitters and anxiety, so I wake up with a calm burst of energy. You can control the dosage as well if you only need a small boost. They are on V2 a month in to my subscription and there is no increase in price which I appreciate. This is a company who is experimenting to find their final product and I'm hear for it.

It's kinda weird. ...
It's kinda weird. You think "caffeine" and you think jittery, wired... With Zest, i wake up suddenly and alert. not at all shaky or tense. Just "up." And because of that, I don't have that anxiety about "am I late? what do I need to do?" I just get up. That is the goal. It offsets a lot of morning stress to wake up feeling like that.
