A reporter for the New York Post tries out the $75 NuCalm system experience at ReCOVER studio in Midtown.

My session begins in a leather recliner chair. Drogoszewski has me rub a gel on my neck that he says will “block adrenaline.” The gel contains GABA, a neurotransmitter, and L-Theanine, an amino acid. They work together to open up the GABA receptors in your brain so that the body can relax, claims Solace Lifesciences, the 16-year-old company behind the NuCalm system. These ingredients are generally recognized as safe by the FDA — but are not cleared for use as a sleep therapy.
