    Transcript of @therealsummermason's video: When it's time to head to bed, I reach for my Zest. Take Zest before you go to bed when energy levels are low. It dissolves while you sleep so that the caffeine is released shortly before you wake up. This means energized mornings, reduced grogginess, improved sleep-wake cycles, enhanced productivity, and steady energy. Shop Zest today.

    Transcript of @shervinshares's video: The Wake Up Pill. This is Zest, from one of my good friends, actually, where you take caffeine before you go to bed, and when you wake up, the caffeine just hits you, so you’re instantly awake. This is what the Zest box looks like. You get a little bag of their supplements that goes inside of here. “Wake up with energy. Take before bed.” I’m excited to try this out, the Wake Up Pill. Time-release caffeine supplement. I think after 7 hours, the Zest caffeine will hit your blood system right as soon as you wake up. “Say hello to morning energy.” “Better for you and the planet.” There’s a refill system that comes in a pouch. “What to expect”: day one, and 3 to 7. You take Zest right before you go to bed and you wake up with energy at 6 AM. Take one capsule with water nightly. I’m excited to try Zest out. Thank you for sending us over. Follow for more.

    Transcript of @oliviaalboher's video: Zest. These are life-changing. Life-changing. We just started taking them. We take one every single night, 30 minutes before we go to bed, and we wake up energized than ever, literally feeling like the Energizer Bunny. Don’t even need a coffee.

    Transcript of @itsethankeiser's video: Does anyone else spend hours on social media when they wake up? Because I wake up and I first go to Instagram, then I go to TikTok. Then I check the stock market, then I go to crypto, and then I repeat the cycle. It’s like a fucking loop. And I do this over and over again. And I wanted to find a way to break this cycle. I found this product. It’s called Zest. It’s like a caffeine pill on an 8-hour timer. So I take it before I go to bed, and then when I wake up, the caffeine hits me or it wakes me up, and it forces me out of bed because I have all this energy. I literally cannot stay in bed. So this is a solution that’s been working for me. It’s called takezest.com. Um, pretty interesting stuff. So if you want to try it for yourself, if you have a hard time getting out of bed, try it for yourself. Put a link here and let me know what you think.
