What I really like about this product is that it has the sleep time herbs such as chamomile, hops, skullcap and passionflower as well as the 2mg of melatonin. I find that this combination of melatonin and herbs works wonderfully when I am having a hard time getting to sleep. It is gentle and effective. Because it doesn't contain Valerian it doesn't give you a groggy feeling the next day. I don't recommend using it every night because that can lead to some side effects like grogginess. I have tried alot of sleep remedies and I have found that overall this supplement is one of the best I've found so far.
