The Details
Green tea has been studied more extensively than almost any other natural compound, and the results are remarkably consistent. The star player is EGCG, a catechin antioxidant that appears to benefit nearly every system in the body.
For metabolism, EGCG supports thermogenesis — the process of generating heat by burning calories. It does this by inhibiting the enzyme that breaks down norepinephrine, allowing this fat-burning hormone to remain active longer. Combined with the natural caffeine in green tea, this creates a modest but measurable increase in metabolic rate and fat oxidation.
The cardiovascular benefits are equally well-documented. Meta-analyses of large population studies consistently show that green tea consumption is associated with lower LDL cholesterol, better blood vessel function, and reduced cardiovascular risk. EGCG also crosses the blood-brain barrier, where it supports cognitive function and may protect brain cells from age-related oxidative damage. At 300mg of extract, you're getting the equivalent antioxidant power of several cups of green tea in a single capsule.

What people say
Really good supplement brand. The daily pack format is so convenient and I've been 100% consistent because of it. The quiz was genuinely thorough. Knocked one star off because I'd love the option to add or remove individual supplements as I learn more about my body.
I've tried so many supplements and honestly nothing has worked like this. The quiz is actually thorough and the results show it. Energy is UP, recovery is UP, sleep is SO much better. Can't believe it took me this long to find this brand.
Three weeks in and I already feel the difference. My morning energy is COMPLETELY different. No more dragging myself out of bed. The personalization through the quiz is what makes it work — it's not just a generic multivitamin. Stack actually thought about what MY body needs.
I've been on a health optimization journey for about three years and have tried what feels like every supplement brand on the market. Most of them are either generic multivitamins dressed up in pretty packaging, or they're so specific that you need to be a nutritionist to understand what you're actually taking. Stack sits in a completely different category. The quiz is the first thing that impressed me. It asks genuinely intelligent questions — not just 'how old are you and what's your gender' but questions about your diet, your sleep patterns, your stress levels, your exercise frequency. It felt like a real consultation rather than a data collection exercise. The pack that arrived was clearly personalized to my answers. After six weeks, the improvements have been consistent and measurable: better sleep quality, more stable energy throughout the day, and noticeably faster recovery after my runs. My partner commented that I seemed more 'on' in the evenings rather than crashing after dinner. The daily pack format is brilliant for compliance — I've been 100% consistent because the habit is so frictionless. One pack, done, every morning. No bottles, no measuring, no forgetting half of them. Genuinely one of the best health investments I've made.
My focus at work has been sharper and I'm waking up without that groggy feeling I used to have every morning. Told two friends about Stack already. Customer support was also really helpful when I had a question about one of the ingredients.
honestly wasn't sure about it at first but three weeks in and i'm so glad i tried it. energy is way better, i'm sleeping properly for the first time in months. the quiz was really detailed which gave me confidence it was actually personalized. would 100% recommend.
