Source Naturals Melatonin is the best!
My husband and I have been using Source Naturals Melatonin for almost 25 years. I have tried a few other brands, and I definitely think Source Naturals is the best! I once saw a program on Discovery channel about how Melatonin is an important heart antioxidant, and that after age 40 the Melatonin in our system goes way down. We had also just moved to a high altitude town, and I was having great difficulty sleeping because of the high altitude. We started taking Source Naturals Melatonin, and I was able to sleep like a baby. I really recommend the time release especially, and we also take a 1 mg sublingual lozenge to fall asleep more quickly.

surprised!
I actually didn't realize I had ordered "time released" version. I thought these were just normal melatonin. But now that I've tried these, I love them so much better than the regular version! Helps me sleep better through the night. No taste, love this brand of Source Naturals.
