WHY THISEXISTS.
The supplement industry runs on hype. SynergyStacks runs on citations. Every stack we publish is built the same way: read the studies, extract the mechanism, grade the evidence honestly, and tell you what we actually know — and what we don't.
The principle.
Most supplement reviews ask "does X work?" That's the wrong question. The interesting question is "does X work better with Y?" — because biology rarely operates through single compounds.
Caffeine stimulates muscle carnitine retention. Fenugreek mimics insulin. Berberine activates AMPK. Eurycoma inhibits aromatase. In each case, the combination does something neither compound can do alone.
We're not trying to sell you a miracle. We're trying to explain why certain pairs work — and give you the tools to evaluate new ones yourself.
The method.
Mechanism first
We don't start with "does it work?" We start with "how would it work?" If we can't explain the biological pathway in plain language, we don't have a stack yet.
Human data preferred
Every claim on this site traces back to a human RCT, meta-analysis, observational study, or — when human data is absent — a clearly labeled animal study or documented case report. We never present animal data as if it were human evidence.
Combination-specific
We look for studies where the combination was tested — not just the ingredients separately. If a stack is only supported by "X works and Y works," that's a Grade B at best.
Honest grading
Grade A = multiple RCTs or meta-analysis. Grade B = strong mechanism, limited human data. Grade C = emerging signal, inconsistent results. Mechanism Preview = animal data only, human RCT pending. We label all four clearly.
Reversible conclusions
If new data contradicts what we published, we update the page and note the change. Science moves. So should we. Every page carries a "last reviewed" date.
No shortcuts
No brand deals. No "sponsored by" posts. No claims we can't cite. No "proprietary blends" worship. No doctor-washing with fake credentials. No presenting animal data as human evidence without a clear label.
Full disclosure.
How we make money
Affiliate commissions. When you click a "VIEW" button and purchase a product, we may receive a small commission from the retailer. This costs you nothing extra. It's how the site stays online.
We only link to products we would personally consider using, and we don't accept payment to include a product in a stack. If we ever run a sponsored placement, it will be marked clearly and won't affect the grade we assign.
What we are not
Not a medical service. We don't diagnose, treat, or prescribe. Nothing on this site is medical advice. If you take prescription medication, are pregnant or breastfeeding, or have a chronic health condition, talk to a qualified healthcare provider before starting any supplement.
Not a supplement seller. We don't sell anything directly. We're an editorial reference, not a store.
