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

Literally, a game-changer for...
Literally, a game-changer for me. The grogginess and "ughhhh fog" that I usually wake with..gone. To be clear, I don't wake up "energized" but I wake up feeling like okay, I can think clearly and clearly, its time to get up. This might sound or seem simple to alot of people but its life changing for me and my day.

Works like a charm.
Works like a charm. I've always struggled with being an energetic morning person. Zest woke me up on the right side of the bed earlier than ever, ready to tackle the day. Couldn't be happier. Customer for life. THANK YOU!!!

A year on Zest
I’ve been taking Zest for about a year now and I have to say it has truly made an impact to my life. I’ve been a very good sleeper my entire life, to put it simply. It’s always been difficult for me to wake up in the morning and I’ve never been a morning person. Now, I wouldn’t say this has turned me into a 5am person but my energy levels and ability to wake up to my first alarm have been improved drastically. I do not experience any negative affects from the caffeine when taken at nighttime either. Absolutely love Zest and it is part of my daily regimen!

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!

Skeptical at first but definitely a believer in Zest!
I was skeptical but it actually works! I feel more awake in the morning and automatically wake up with energy that I don’t typically have until later in the morning.

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.

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!

Works, sort of
I really like this concept, but the pills only work so-so for me. The timing can be variable, once I was awake just 4-5 hours after taking a pill, another time I slept over 9 hours. I do feel a difference (usually) after waking up, but it's more subtle than I expected - it's certainly not boundless energy. I will probably keep trying the product for at least another month, perhaps it just takes some getting used to.

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!
