This is such a great product, a great blend that really works & the value on Swanson site is fabulous----I pray they continue this offering in this quantity--Is stopping my trips to a competitive "V Shoppe" for the value & convenience of offering this quantity... August 8, 2012
Great, effective product My mom and I both love this product. Helps you get a restful sleep. One awesome add on benefit is if you forget to take it or think you don't need it and then 4am rolls around and you can't sleep, it's fine to take it, you'll at least get a few solid hours and it won't make you drowsy in the morning.
