06 Nov 2023 --- In a four-week clinical trial, study participants consuming MDBio’s sleep supplement observed significantly improved sleep quality — as they reported fewer sleep disturbances — anxiety, stress and well-being compared to a placebo group. The supplement, MDsleep + hemp, contains a mix of cannabinoids, herbs and botanicals. “MDsleep contains cannabidiol (CBD), cannabinol (CBN), delta-9 tetrahydrocannabinol (THC), valerian, chamomile, hops, gamma-aminobutyric acid (GABA) and L-theanine, which work synergistically to support sleep,” Brenden Dougherty, CEO at MDBio, tells Nutrition Insight.
