Over-the-Counter Supplements

Capsules, powders and 'fat burners' sold without a prescription — where we find the widest gap between marketing and evidence.

Dietary supplements are not approved by the FDA before they go on sale. Manufacturers are responsible for their own safety and labelling, and enforcement is largely after the fact. That structural reality shapes how we score this category: we weight third-party testing and ingredient transparency heavily, and we treat any product making a specific pound-loss promise as a red flag rather than a feature.
