The reviews are in — and they've been loving the results.
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…
Enjoying Stack so far. I'm about 7 weeks in and energy has improved, sleep is more consistent. The personalization feels real and not just marketing. Minor thing — the quiz could ask a few more questions about dietary restrictions.
Solid product, real results. Just wish there was an app to track progress. Energy and sleep both improved noticeably.

Solid product that does what it promises. My sleep has noticeably improved and the daytime energy is more stable. Dropped one star only because I had a small shipping delay — but customer service sorted it quickly. Would still recommend.
Very happy with Stack overall. The packaging is clean, delivery was quick and the quiz was thorough. I just wish the website had a bit more education around each ingredient and why it was included in my pack. Results have been good though — energy and sleep both improved.
great product overall, the personalization definately works. i've noticed better sleep and more stable energy after about a month. only thing is i wish the website explained a bit more about each ingrediant in my pack. but the results have been good so i'll keep going.
Really solid supplements and the personalization aspect is legit. Shipping was super fast too. Only reason I'm not giving 5 stars is I wish there was an app to track how I'm feeling over time. Product itself is great though.
really good product and good concept, i like it alot. the quiz was alot more detailed than i expected and the packs are super convienent. been on it for about 6 weeks and definitly feeling better energy wise. would recomend to anyone looking for personalized supplements.
Happy with my Stack experience. The quiz was detailed, the packs arrived quickly and I've felt improvements in sleep and energy. My one suggestion would be a mobile app to go alongside the subscription. Otherwise great.
good product, nice packaging, the quiz was solid. been taking it for 5 weeks and definitely feeling more energy during the day. would give 5 stars if there was an app to go with it but that's a minor thing. overall recommend.
Three months in and genuinely pleased. The personalization through the quiz works well and I've felt real improvements in energy and focus. Minor feedback — it would be great to have an option to update my quiz answers as my lifestyle changes.
Solid product, real results. Just wish there was an app to track progress. Energy and sleep both improved noticeably.
