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

Improved Sleep Inertia
So far it is helping a bit. I still struggle a little in the mornings, but before, I could sleep through my alarm for over an hour. Now I actually wake up to my alarm, but I still feel a little bit groggy and tired. I'm assuming this will get better over time, but honestly, just being able to wake up is a huge improvement to me. I do wish they had a little bit more oomph though. Caffeine is not as strong for me as it is for others, but the other ingredients are probably helping with that. I do still feel like I need to take my Adderall in the morning. I'm not AS tired throughout the day as I usually am. If there was a stronger version for people who aren't sensitive to caffeine, I would definitely buy it! Or maybe take three instead of 2 before bed? I won't do that before looking into if it is okay to do though. I'm hoping it just gets better as I continue to take them!

This pill is life changing - no need to drink caffeine all day & no more snoozing my alarm!
This pill has changed my life, I swear by it to everyone I talk to nowadays. I am the opposite of a morning person, usually sleeping until the last minute, snoozing at least 6 alarms, before finally being able to crawl out of bed & it would take at LEAST an hour or more to fully wake up/dispel

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.

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.
