This book provides general education, not individual medical advice; consult a qualified professional before using a supplement.
The method, in plain view
How to read the grades
The book includes an A–E grading key. Chapter verdicts explain the evidence, value and safety in words, without displaying individual letter grades.
Look for the claim, the form studied, what the research measured and where the evidence stops.
- Grade A: Strong and directly relevant
- Grade B: Supportive with meaningful limits
- Grade C: Uncertain, mixed or modest
- Grade D: Little reliable support
- Grade E: No meaningful benefit, or an unfavorable proposition
Missing research is not the same as evidence of no benefit. E does not mean “we do not know.”
Research and its limits stay together, including what has not been established. A grade is not a treatment recommendation or a guarantee of personal benefit.
Questions, answered with context.
Does a supplement that works always offer good value?
No. A real effect may be too small, expensive or dependent on specific circumstances to justify a purchase. The book separates evidence of benefit from value for money.

Does Supplements Decoded recommend every supplement?
No. The book weighs evidence, cost and relevance, including situations where food, sleep or a conversation with a clinician may be more useful.

Does Supplements Decoded include an A–E grading key?
Yes. The front matter includes an A–E key. Chapter verdicts explain their assessments in words rather than displaying individual letter grades.
