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.

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

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.

Just get it now! You won't regret it.
I can not say enough how this has improved my life. As someone with POTS mornings are hard. This has changed everything and I wake up before my alarm for the first time in years finally!

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!

Great but 10h release time would be better
I wish it released more than 8h later. This way you could have more flexibility of when you take it vs bedtime vs wake up time.

Zest is the real deal!!! If you haven’t ordered, get on the subscription before this goes mainstream and becomes hard to get. I take mine at 9PM every night and wake up at about 5:30 ready to attack the day!!! Great product and incredible experience with no side effects!

Highly satisfied!
Life Changing!
I was skeptical at first, but this product truly lives up to its promises. Since I started using it, I wake up feeling focused, energized, and ready to take on the day. It’s made a noticeable difference in my daily routine—I feel better than I have in years. Highly recommend to anyone looking for a real boost!

I'm a lifelong customer...
It took a couple weeks for me to really feel the effects, but now Zest has completely changed my mornings. I wake up almost every morning, no alarm clock, after 7-7.5 hours of sleep. I'm a lifelong customer.
