About Nutrient Ledger

Nutrient Ledger is a new educational publishing project for US readers who want clearer information about supplements. Our initial focus is creatine, oral collagen and amino-acid products.

We help readers understand supplement evidence, compare labels and consider costs. Read our editorial policy for how we develop our guides and describe their limitations.

Our aim is practical: connect a claim to its source, explain what a label tells you and show when a comparison cannot support a confident answer.
