Stop Blinding Your Biology.
Master 89,000+ Supplement Interactions.

Generic apps miss nutrient blocking and toxicity. Stochi analyzes your stack against PubMed-backed data to optimize ratios like Zn:Cu and prevent serotonergic risks in real-time.

Manual tracking failed you.

You tracked the dosage. You missed the pharmacokinetics. Your spreadsheet doesn't know that Magnesium competes with Zinc for the same transporter. We do.

Your Spreadsheet is Missing These Lethal Errors.

These pharmacokinetic patterns exist in most stacks. Your spreadsheet cannot detect them. Stochi scans for all of them in real-time.

The Absorption Block[PMID:9701160]

Zinc depleting Copper stores

High-dose Zinc (30mg+) without Copper causes gradual depletion. Symptoms appear after months: fatigue, anemia, neurological issues.

CRITICALZn:Cu ratio exceeds 15:1
Add 2mg Copper per 30mg Zinc
The Toxicity Threshold[PMID:25441954]

Cumulative Upper Limit breach

Vitamin A and Selenium from multiple sources can silently reach the Upper Limit (UL). Liver toxicity and selenosis develop without warning.

CRITICALCombined sources exceed UL
Audit all Vitamin A / Selenium sources
The Half-Life Conflict[PMID:2507689]

Fat-soluble vitamin without fat

Vitamin D, K, E, A require dietary fat for absorption. Taking on empty stomach reduces bioavailability by up to 50%.

WARNINGD3/K2 logged without meal flag
Take with fatty meal
Pharmacodynamic Risk[PMID:32818573]

Serotonergic compound stacking

Ashwagandha, 5-HTP, St. John's Wort enhance serotonin. Combined with SSRIs, risk of serotonin syndrome increases.

Outcome

"I thought the fatigue was just aging. Stochi found the Zinc/Copper imbalance on day one. Added 5mg Copper, split my mineral timing. Energy returned within 3 weeks. Four years of spreadsheets missed what Stochi caught instantly."

Stop guessing.

Your stack might be fine. Or it might be working against you. Only a diagnostic will tell.
