Supplement Stacks
Goal-based combinations of supplements that work together — picked from Formulate's ingredient encyclopedia by evidence grade, mechanism, and known safety. Each stack includes doses, timing, and any interaction warnings you need to know about.
Sleep Stack
Four evidence-backed supplements that improve sleep quality without sedating you the next morning.
Cognitive Stack
Four ingredients with human-trial evidence for memory, focus, or processing speed — not the kitchen-sink nootropic shopping list.
Immunity Stack
The foundational immune stack — vitamin D year-round, zinc + quercetin + vitamin C for acute illness, not daily mega-dosing.
Longevity Stack
Five supplements with either strong aging-biomarker evidence or strong all-cause mortality / disease-prevention evidence.
Recovery Stack
Four compounds that reduce post-training inflammation and support the adaptation your workout was trying to produce.
Gut Health Stack
Four evidence-backed supplements for microbiome support, regularity, and gut-barrier integrity — not another kombucha fad.
Men's Testosterone Stack
Evidence-based supplements for low-normal testosterone — micronutrient basics first, then the herbs with real RCT data.
Mood Support Stack
Supplements with RCT-level evidence for mild-to-moderate depressive symptoms — adjunct to, not replacement for, clinical care.
Cardiovascular Stack
Four compounds with large-trial evidence on heart disease endpoints — not biomarker-only pixie dust.
Metabolic Stack
Four supplements with RCT evidence on blood sugar, triglycerides, or insulin sensitivity — the real metabolic risk markers.
Every ingredient in every stack links to a full evidence-graded profile in the ingredients encyclopedia. Before combining any stack with prescription medication, run it through the interaction checker.
