Know what is in your supplement cabinet, what it costs, and what to ask your doctor or pharmacist about it.

What you get, instantly after checkout:

• A 20-product inventory: adds up your monthly and yearly cost.
• 33 supplements graded A to D: forms, usual doses, upper limits and what the studies found.
• An upper-limit tally: adds every source of 12 nutrients and flags under, near or over the limit.
• An interaction screen and a daily schedule: questions to ask by medicine type, and when to take what.
• Seals decoded: USP, NSF, ConsumerLab and more, and how to read a certificate of analysis.
• A clinician one-sheet: one page to photograph and hand over at your next appointment.
• 46-page fillable PDF e-book: print it, or type into it on screen; the calculations work in Adobe Acrobat Reader, Chrome, Edge, Firefox and Foxit.
• Free bonus: an online edition of the same e-book for any phone, tablet or computer.

Digital product: a fillable PDF download plus online access. Nothing is shipped. One payment, no subscription. 60-day money-back guarantee. An educational and organizational tool, not medical advice.
