What is Stack412?
A curated storefront for the functional-wellness crowd. We aggregate the best brands across non-alcoholic drinks, nootropics, adaptogens, sleep, recovery, performance, and gut health — so you can shop 500+ direct-to-consumer makers without bouncing between sites.
How do you pick what's listed?
A quality bar — 4.0★ minimum, real reviews, real product imagery, and a curation filter so only the functional stuff makes it through.
Where do I actually check out?
On the seller's site. We hand you off cleanly — your card, address, and order go directly to the brand. We never see your payment info.
Do prices stay current?
Yes. Our catalog refreshes daily across every brand we carry. Variants you see have been verified within the last 24 hours.
Can I build a custom protocol?
Yes — take the 60-second quiz or use the AI Protocol Builder. We compose a personalized stack and email you a shareable link.
Are these affiliate links?
Not today. We don't take a cut of what you spend with the brands. When industry-wide commission rails launch (Spring '26+), we'll be transparent if that changes.
