Supplement labels and evidence across markets
Global Supplement Review focuses on supplement ingredients, product labels and evidence questions for readers in different markets. A brand name alone does not establish the same formulation, price, seller terms or availability in every country.
What to check before comparing products
- Identify the exact product, formulation, serving size and country on the current label.
- Separate research on an ingredient from evidence about the finished product, and check study population and limitations.
- Confirm the seller, storage conditions, returns and local rules with current primary sources before buying.
