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.

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!

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.)
