Valerian is often promoted as a sleep aid and to help with anxiety. But does it really work, and if so, which products are best? ConsumerLab.com purchased and tested popular brands and reviewed the latest clinical research to find out.
Compounds known as valerenic acids are thought to be responsible for valerian's effects on the nervous system. However, our tests found that many valerian supplements don't provide the amount of valerenic acids shown to be effective in some studies, and a few don't even contain levels expected from the amounts of valerian listed on their labels.
