FDA doesn't monitor supplements
Dietary supplements aren't approved and monitored by the FDA the same way medications are. You can't always be certain of what you're getting and whether it's safe. Also, because some herbal and other dietary supplements can interfere with prescription medications or cause dangerous interactions, talk to your health care provider before taking any supplements.
