Nuvana is a perfect stocking stuffer. Nuvana’s Shut Eye was created by an LA-based neurologist and biochemist to improve sleep with a natural sleep aid. Shut Eye packs a one-two punch of the amino acid L-Theanine and the neurotransmitter GABA. Together they help the brain to down-regulate feelings of worry, stress and anxiety to create a state of relaxation which makes it easier to fall asleep and extend the duration of deep sleep. Also available on Amazon.
