Product Overview


  • Promotes Relaxation & A Healthy Sleep Cycle
  • Dietary Supplement
  • Potent Formula to be Taken Only at Bedtime

Jarrow Formulas Sleep Optimizer combines herbs and amino acids that work together to facilitate falling asleep and maintaining a regular sleep cycle. Gamma-aminobutyric acid (GABA), lemon balm and L-tryptophan promote relaxation. The combination of valerian and hops flower has been studied for its effect on reducing latency (the delay before entry into sleep). Melatonin is a hormone, secreted by the pineal gland that controls the biological clock and signals the entry into sleep. Our biological clock can be disturbed by stress, crossing time zones and changing work shifts.

Suggested Use

Take 2 capsules 20 to 30 minutes prior to bedtime, or as directed by your qualified healthcare professional.

Other Ingredients

Silicon dioxide and magnesium stearate (vegetable source). Capsule consists of gelatin.

No wheat, no gluten, no soybeans, no dairy, no egg, no fish/shellfish, no peanuts/tree nuts.

Didn't help with insomnia at all

No effect

My mother took these and she felt nothing. She sleeps so much better with Silent Night from Nature's Way.

Thanks for your feedback!

Bad experience

Posted by iHerb Customer on Mar 08, 2014 | Verified Purchase

I did not like this at all. Yes, I fell asleep easily, but during the night I woke a dozen times in bursts of restlessness. Very shallow sleep, felt almost tired in the morning.

Thanks for your feedback!
