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. 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!!!

I Wanted to Love It, But Convenience Wins
I like the concept and, on the occasions I remembered to take it correctly, I noticed some genuinely good results. It gave me a nice boost and I woke up feeling more energized.
My biggest issue is the timing. I tend to eat late, and since you’re not supposed to take it with food, I often realize I’ve missed the window and end up skipping it altogether. That makes it difficult to build into my routine.
The other factor is convenience and value. Lately I’ve been using caffeine/energy pouches that I can simply pop in my mouth whenever I need them. They provide 100 mg of caffeine plus other focus and energy ingredients, work almost immediately, require zero planning, and cost significantly less.
I still think Zest is a good product and the idea behind it is solid, but for my lifestyle the extra planning and higher cost make it hard to justify over a more convenient alternative. If it were more affordable or easier to fit into a flexible schedule, I’d be much more likely to use it regularly.

Works well to wake up refreshed and less tired
On my 3rd day of using Zest. So far it’s working well for me. I’m sleeping well and waking up feeling less tired and with more energy. The only downside I’ve noticed is that I’m getting a little additional sweating in my armpits about 15 mins after waking up. Nothing too heavy , but more than usual.

Skeptical, at first
My wife and I were skeptical at first. Then we missed a day, and could tell a substantial difference in our energy in the morning. Great product.

Wow - they actually work!
I have only been taking this for about a week, but it's a game-changer! I take two capsules around 10pm, and when my alarm goes off at 6am I am able to get right up without the usual stumbling to the kitchen for a coffee or energy drink. I'm really impressed as how much less painful my mornings have been this week.

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!

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!
