That’s the real gap: not the pills, not your discipline, just missing data. Litmus logs your stack in a tap, shows the research behind every ingredient, and reads out what your own numbers say. All of it yours to keep.
Free. iOS, launching soon. No spam, ever.
Built on public, auditable data · NIH DSLD · PubMed · openFDA
So Litmus removes the homework. Point your camera at the shelf and it reads every label into your stack: product, form, dose. Scan a barcode for one bottle, or search 214,788 products for the rest. Reminders match your actual routine, and logging a whole morning is one tap. The lazy path and the correct path are the same path.
In Litmus, every summary opens. Tap a product for what’s actually inside it. Tap an ingredient for what the research measured. Tap the research for the paper itself. Tap your own history for what’s changed since you started. Depth is always one tap down and never in the way.

Blood Pressure
Magnesium supplementation only marginally lowers blood pressure by a few millimeters of mercury, though the FDA has approved a qualified health claim stating that consuming adequate magnesium may reduce hypertension risk.
Bone Density
Some studies have found that higher magnesium intakes are associated with increased bone mineral density, and limited evidence suggests magnesium supplementation may increase bone mineral density in postmenopausal women with osteoporosis.
Migraine Disorders
Three out of four small clinical trials found modest reductions in migraine frequency with magnesium supplementation up to 600 mg/day, and the American Academy of Neurology and American Headache Society concluded that magnesium is probably effective for migraine prevention.
