Cost and Quality of Dietary Supplements -- supplement bottles on store shelves


You certainly don't need to pay the highest prices to get good quality supplements and cost is not an accurate predicter of quality. ConsumerLab tests have found some of the most economical products, costing pennies a day, are of better quality than premium-priced supplements costing more than a dollar a day.

Here are some examples of how much (or little!) you need to spend to get top-quality supplements based on the products we have tested. Use the links to go to the reports and see the products and learn more about them.
