Tryptophan
This essential amino acid – famous for inducing post-Thanksgiving drowsiness – serves as a precursor to melatonin. It has been shown to play a crucial role in regulating both mood and sleep, supporting a more peaceful slumber.
GABA
With its unique properties, GABA may actively reduce the time it takes to fall asleep. By calming your body's nerve responses to the brain, GABA may help support a state of relaxation, allowing your mind to disconnect and unwind.
Magneium
As an essential mineral, magnesium may help boost melatonin levels, which may improve the quality and duration of your precious sleep.
Rutaecarpine
This remarkable natural compound may boost the breakdown and excretion of caffeine, supporting an efficient detoxification process.
Chamomile
Embrace the soothing effects of chamomile – the gentle flower often known for its presence in many "sleepy-time" teas. Acting as a natural sedative, chamomile aids in relaxation which may lead to improved quality and length of sleep.
Hops
Hops may be considered a natural sedative that may help you achieve a longer and more restful sleep.
Passion Flower
Passion Flower is known for its calming effects and may help promote restful sleep.
Valerian Root
Valerian Root may ease restlessness which may help reduce the amount of time it takes to fall asleep.
Experience the secret to a night of blissful rest – and a stronger immune system. Say goodbye to sleepless nights and embrace a rejuvenating slumber that leaves you refreshed and ready to conquer each day with vitality and vigor.
