The Details

Why you'll love it

NAD+ (nicotinamide adenine dinucleotide) might be the most important molecule you've never heard of. It's present in every cell of your body and is required for hundreds of metabolic processes, including converting food to energy, repairing damaged DNA, activating sirtuin longevity proteins, and maintaining cellular health.

The problem is that NAD+ levels decline dramatically with age — by roughly 50% between your 40s and 60s. This decline is now believed to be a key driver of aging at the cellular level, contributing to mitochondrial dysfunction, accumulated DNA damage, and the metabolic slowdown associated with getting older.

Nicotinamide Riboside is one of the most efficient precursors for raising NAD+ levels. Clinical trials in humans have confirmed that NR supplementation significantly increases NAD+ in blood and tissues within weeks. While the long-term longevity benefits are still being studied (the animal data is incredibly promising), the cellular mechanisms are well-established: higher NAD+ means better mitochondrial function, more efficient DNA repair, and activated sirtuin pathways. At 300mg, this is the dose used in the landmark human clinical trials.

What people say

Strong results after 6 weeks

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.

Rafael N.

Stack is AMAZING

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.

Hassan T.

Best decision I made this year — HANDS DOWN

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.

Isabella J.

A genuinely thoughtful supplement brand

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.

Noticed results within 3 weeks

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.
