Know What Is in Your Supplement Cabinet, and Why
Supplement lists grow one bottle at a time and are almost never reviewed. This e-book takes the cabinet apart: an inventory that adds up what you spend, a directory of thirty-three common supplements with the evidence graded A to D, a tally that adds every source of twelve nutrients against the upper limit, an interaction screen, a daily timing plan and a one-sheet for your clinician. It does not tell you what to take. Delivered instantly as a 46-page fillable PDF e-book, with a free bonus: an online edition of the same e-book for any phone or computer.

Why Most Advice Leaves You More Confused
What’s Inside the Complete System
Every section is authored to provide concrete, fillable tools rather than theoretical filler.
The Audit and the Label
Why cabinets need auditing, the three questions every bottle must answer, a 20-product inventory that adds up the monthly and yearly cost, how to read a Supplement Facts panel, and label math that converts compounds to elemental doses and IU to mcg.
Thirty-Three Supplements, Graded
From the multivitamin and vitamin D to berberine, ashwagandha and red yeast rice: forms, usual doses, upper limits, what the trials found, safety, what each stacks with and the test that goes with it, graded A to D.
Is It What It Says?
USP, NSF, ConsumerLab, BSCG and Informed Sport compared; which seal for which need; six label claims that test nothing; how to read a certificate of analysis; and the recalls that shaped the rules.
Adding It Up
Sixteen upper limits and where the extra comes from, a tally that adds every source of twelve nutrients and labels each one under, near or over the limit, and six real cabinets worked through.
Interactions and Timing
Twenty supplement interactions with prescriptions and lab tests by level, twelve conditions that change the rules, questions by medicine type, a day in six slots, and what helps or blocks absorption.
The Clinician One-Sheet and Stop-Trial
A one-sheet to photograph and hand over, ten prompts, a decision log, side effects and where to report them, a four-week stop-trial that calculates, and nine checks before the next purchase.
Three Steps, a Few Minutes a Day
Empty the cabinet
Every bottle, powder and gummy goes on the inventory, including the multivitamin. Look each one up in the directory and give it a grade.
Verify, add up and time
Check each seal online, add every source of each nutrient on the tally, screen for interactions and give each product a slot in the day.
Hand over the one-sheet
Bring the one-sheet and three prompts to your clinician or pharmacist, record what was decided, and repeat the audit once a year.

Is This System Right for You?
- Adults taking three or more supplements, or a multivitamin plus single nutrients.
- Anyone on prescription medicines who wants a clear list to check with a pharmacist.
- Caregivers keeping track of a parent's or partner's cabinet.
- People who want to spend less on supplements without guessing which to drop.
- It does not tell you to start, stop or change a supplement or medicine; those decisions belong with your clinician or pharmacist.
- It is not a substitute for a pharmacist's interaction check, especially with blood thinners, thyroid medicine, transplant or cancer drugs.
- If you have new symptoms after starting a product, contact your clinician first; Chapter 9 lists the signs that need same-day help.
Clinical Evidence & Scientific Grounding
Doses and upper limits follow the NIH Office of Dietary Supplements fact sheets and the Dietary Reference Intakes. Regulation follows DSHEA (1994) and 21 CFR Part 111. Prevalence follows Mishra (NCHS Data Brief 399, 2021) and emergency visits Geller (N Engl J Med 2015). Evidence grades draw on the primary trials and Cochrane reviews named in the e-book, including VITAL (Manson 2019), REDUCE-IT (Bhatt 2019), STRENGTH (Nicholls 2020) and SELECT (Klein 2011); fish oil and atrial fibrillation on Gencer (Circulation 2021); liver injury on the US DILIN registry (Navarro, Hepatology 2017) and EFSA (2018); melatonin content on Cohen (JAMA 2023). Certification programs are described from USP, NSF, ConsumerLab, BSCG and Informed Sport.
