MoodStack scans any supplement and breaks down every ingredient with its real dose

The problem

Most labels are marketing.
The signal is buried.

Forms

Same name. Different molecule.

Magnesium glycinate absorbs 4× better than oxide. The bottle doesn't tell you which one you're holding.

Doses

Below the clinical threshold.

“Proprietary blends” hide per-ingredient doses, often below the level studies actually used.

Evidence

Cited, not claimed.

Every product graded on form, dose, lab testing, brand transparency. Sources go to PubMed.
