The Details
Magnesium deficiency is the silent epidemic you probably have. Experts estimate that up to 75% of Americans don't meet the recommended daily intake, and standard blood tests miss most deficiency because only 1% of your body's magnesium is in the blood (the rest is in bones and tissues).
Magnesium is involved in over 300 enzymatic reactions in your body, including energy production, protein synthesis, muscle and nerve function, blood sugar regulation, and blood pressure control. When levels are low, the effects ripple everywhere: muscle cramps, poor sleep, anxiety, headaches, and impaired recovery.
We specifically chose the glycinate form because it's the gold standard for relaxation and sleep. Unlike magnesium citrate (which can cause loose stools) or magnesium oxide (which has terrible absorption), glycinate is highly bioavailable and exceptionally gentle on the stomach. The glycine component adds its own calming benefits — it's an inhibitory neurotransmitter that supports relaxation and sleep quality. It's the perfect form for evening use, helping you unwind, sleep deeply, and wake up with muscles that feel recovered rather than locked up.

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.
