Key item features

  • SUPPORT YOUR SEROTONIN LEVELS – You’ve probably heard of serotonin. It’s a neurotransmitter that is deeply involved in both restful sleep and positive mood. But what you might not know is that your body needs adequate levels of the essential amino acid tryptophan to make it.
  • GET SOME SHUTEYE – Modern lifestyles seem to revolve around not getting enough rest—but that’s not healthy. To keep your body healthy, you have to let it rest. L-Tryptophan encourages serotonin production, which in turn promotes restful, restorative sleep patterns.
  • MOOD (AND MUNCHIES) – What else is tryptophan good for? Well, it promotes a healthy mood (that’s the serotonin again) and it also promotes satiety: the sensation of being full. Tryptophan also encourages your body’s healthy response to stress.
  • Ingredients matter – We use only pure, high-quality ingredients. The majority of our products are non-GMO and gluten-free—and a Certificate of Analysis is available for every one.
  • Live your healthiest life - For over 40 years, we’ve been developing advanced, effective formulas made with the highest standards and based on the latest scientific findings. We believe the answers to a healthier, richer life are within reach, and that rigorous scientific research is the path to get us there. That’s why so many of our nutritional formulas are designed using specific ingredients and amounts based on scientific studies.

Sweet Dreams

I have been able to fall asleep easily and I feel so much better when I wake up. This does not make me groggy at all! I will buy this again! [This review was collected as part of a promotion.]

formula for falling asleep

when i have a sleepless night from an overactive mind the combination of three supplements allows me to fall asleep: melatonin (3mg), tryptophan, and ashwaganda. i get so sleepy i sometimes oversleep by an hour or two! but that feels so much nicer than insomnia.
