Contains ingredients important for sleep, regulating the stress response, and reducing anxiousness*

  • Calming Neuro-Adrenal Support - Decreases norepinephrine and contains ingredients important for regulating the stress response, sleep, and reducing anxiousness.*
  • The Most Active Rhodiola - When comparing Rhodiola supplements, what matters most is the amount of rosavins, its active ingredient. An analysis of public formulas showed Calm PRT contains more than triple the amount of active rosavins (112.5mg) from Rhodiola to the closest competitor.*
  • Minimize Sleep Disruptors - Support calm thoughts and a comfortable body temperature to help you sleep through the night. Glycine binds to receptors that regulate temperature during sleep.* Phosphatidylserine is thought to interact with cell membranes to dampen hypothalamic signaling and regulate stress response.*
  • Decrease Norepinephrine - Elevated levels of norepinephrine, produced by an adrenal stress response, can disrupt sleep patterns and perpetuate stress, anxiousness, and fatigue. A data analysis demonstrated a significant decrease in norepinephrine following the use of Calm PRT.*
  • Practitioner Trusted, Professional Grade - Trusted by thousands of healthcare professionals, NeuroScience formulates products exclusively on peer reviewed studies. All products are USA manufactured in a cGMP compliant facility.

Key ingredients:

  • Rhodiola rosea root extract (15% rosavins): Adaptogen shown to reduce anxiousness and stress-related effects (1,2).*
  • Phosphatidylserine: Component of cell membranes important for receptor-mediated interactions (3).* Phosphatidylserine is thought to interact with cell membranes in order to dampen hypothalamic signaling and regulate the stress response (4).*
  • Glycine: Major inhibitory neurotransmitter that crosses the blood-brain barrier (5).* Binds receptors that regulate temperature during sleep (6).*
  • Taurine: Neuroprotective amino acid that provides antioxidant protection and demonstrates GABA-A agonist activity (7-9).* GABA is the primary inhibitory neurotransmitter in the brain important for calm and sleep (10-12).
