Ingredient story:

Valeriana officinalis, commonly known as valerian, is an herb native to Europe and Asia whose roots have been used since ancient Greek and Roman times as a sleep promoter. It plays a role prior to and during N1 (first sleep stage), when the body needs to feel calm, relaxed, and drowsy in order to move to N2 (second sleep stage). By working synergistically with a natural amino acid known as GABA, valerian root extract ensures a more relaxed, calm state.

  • Works synergistically with GABA to ensure a less stimulated response
  • Together, the two promote a more relaxed, calm mind and body
  • Promotes restful sleep

Core Sleep contains 300 mg of valerian standardized to a clinically beneficial dosage of 0.8%.
