Health journals built on real research, not hype.
Understand your health. Make room for better questions.
I'm An Thanh Tùng, the author behind Your Body, Decoded.
My work begins with everyday health questions: Is this supplement worth taking? Why am I still tired? Which advice deserves my attention, and which claims need a closer look?
Through my books, I explore what research can tell us, where the evidence is uncertain, and how to explain it in plain language. This shop brings that same approach to practical journals, trackers and printable worksheets.
The idea is simple: useful information deserves a place in everyday life. A place to write down what you take, record what you notice, and keep the questions you want to ask at your next appointment.
The collection now includes three journals: the 12-Week Skin Diary, the 31-Day Dry January Tracker and the Supplement & Medication Log. Each one is drawn from a book in the series, labels every science claim by the strength of its evidence, and works on its own; no companion book is required. Printable and fillable PDF versions let you choose between writing by hand and typing into a compatible PDF reader.
I aim to make each resource clear, approachable and useful enough to return to, not another complicated system to keep up with.
Please check each listing for the included files, paper sizes and software requirements. Digital downloads do not include a physical product.
These resources support personal record-keeping and health education. They do not replace advice, diagnosis or treatment from a qualified healthcare professional.
Trustworthy science. Usable advice. Honest limits.
Thank you for making Your Body, Decoded part of your routine.
