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.
