About

StackGuard

Read full description

For people stacking 10+ supplements who worry about overlap and overdose risk. It's 2am. You're Googling 'magnesium + zinc absorption' for the third time this week. You take 11 supplements daily and you're not entirely sure they aren't canceling each other out. StackGuard is built for serious supplement users — biohackers, nootropic stackers, athletes managing recovery protocols. If you've ever opened a spreadsheet at midnight to figure out whether your B6 dose is too high, this app is for you. WHAT IT DOES - Track 10+ supplements with timing and dosage - Spot overlap before it happens (magnesium + zinc absorption conflicts, etc.) - Detect overdose risk against NIH DSLD upper limits - See effects over weeks — what's actually working - Color-coded daily schedule for morning/midday/evening stacks WHY IT EXISTS Built by a solo dev who stacks 11 supplements daily and got tired of opening 6 browser tabs every time he added a new one. Made with paranoia. For paranoid users. DATA SOURCES - US NIH Dietary Supplement Label Database (DSLD) - Korean MFDS supplement registry - Conflict detection based on published absorption interaction research PRIVACY Your supplement data stays on your device. No analytics tracking what you take. No selling data to vitamin companies. WHO IT'S NOT FOR If you take 1-3 supplements casually, you probably don't need this. StackGuard is for the person whose pill organizer has more than 7 compartments.

Verdict

The call

The clearest difference is ads: My세브란스 at none against StackGuard's shown. StackGuard's advantage is update cadence (every 5 days vs every 3 months). On price, in-app purchases, device support and iOS requirement there is nothing between them.
