Every stack, every deep-dive guide, every brand recommendation — organized by goal. Start with the Foundation, then layer what you need. Updated March 2026.
Every stack on this site follows a single logic: Foundation first, specialty second. The Foundation Stack addresses the deficiencies that undermine everything else. Once it's running consistently for 4–6 weeks, you add the specialty stack that matches your primary goal.
The stacks are designed to layer cleanly — a supplement in the Foundation Stack (like magnesium glycinate) doubles as a Sleep Stack ingredient. You don't rebuy it, you just note its role in both contexts.
Lion's Mane, Alpha-GPC, L-theanine + caffeine, bacopa monnieri, magnesium L-threonate. Designed for sustained cognitive performance and long-term neuroprotection.
Built on top of the Foundation Stack. Adds protein targets, beta-alanine, citrulline malate, and ashwagandha for recovery and testosterone support.
Targets sleep quality, not just onset. Magnesium glycinate (already in Foundation), L-theanine, apigenin, and glycine. No dependency, no hangover.
Builds on the Foundation's D3+K2 and omega-3. Adds NMN or NR (NAD+ precursors), resveratrol, CoQ10 ubiquinol, and rapamycin-adjacent compounds.
Ashwagandha KSM-66 (cortisol), rhodiola rosea (energy + resilience), saffron (SSRI-comparable mood support), and L-theanine for acute calm.
Collagen peptides, hyaluronic acid, astaxanthin, silica, and biotin (if deficient). Builds on Foundation's omega-3 and vitamin D for skin barrier function.
Builds on Foundation's vitamin D3. Adds zinc, vitamin C, elderberry, and beta-glucan mushrooms for innate and adaptive immune support.
Every brand we link to has been evaluated for third-party testing, label transparency, and quality of manufacturing. We use affiliate links — your price is never affected.
