Take one of these at dusk every day and it helps my loss of melatonin production at age 65...works for me and Dr. Sandra Cabot's products are all noteworthy!<br /><br />(As we age, our own natural production of melatonin decreases so I supplement with a natural product...the key is to take it at dusk when the normal body puts off it's supply of melatonin preparing the body for night's rest)

Been taking this for about six weeks. Energy is more consistent and I feel less sluggish in the afternoons. Happy with the purchase.

Works well. Deducting a star because the bottle is hard to open with one hand, but the product itself is solid.

Third-party tested, clean label. That's what I look for first. Actually works too, which is a bonus.

Switched from a more expensive brand and honestly can't tell the difference in results. Saves money.

Good quality supplement. About three weeks in and noticing a difference, mostly in energy levels.
