Independent supplement reference
Decode what's on the label.
The Biology Code reads the fine print so you do not have to: the actual ingredients and doses, what the research does and does not show, who is really selling it, and whether anyone independent has tested it.
- 1Serving size sets the scale for every number below it.
- 2% Daily Value is per serving, and it can run far past 100%.
- 3A blend lists a total, not what each ingredient contributes.
Illustrative label, not a real product.

The four checks
Same test, every entry
Actives
What is in it and how much. Whether the label shows each dose or hides them inside a blend.
Claims
Whether the promises on the box and the sales page line up with what human studies actually found.
Guarantees
Price, refund terms, and who is really behind the product, in plain view or not.
Testing
Whether an independent lab or certification program has verified the product, or only the seller says so.
Field Notes
Short explainers on how to read the category
How to Read a Supplement Facts Panel
Work out what one serving actually contains, and what the label leaves unsaid.
What Third-Party Testing Seals Actually Mean
Tell an independent check from a marketing line, and look a seal up in the certifier’s own directory.
Why the Form of a Nutrient Matters (and When It Does Not)
Separate the amount of a compound from the amount of the nutrient, and judge a premium form before paying extra.
