At Formula30A we are committed to ongoing research along with provider and patient education. For these reasons, we felt it was essential to create the Formula30A Medical Advisory Board. Our board is comprised of medical professionals from around the nation from varying disciplines whose goal is to guide and direct our product development, conduct clinical trials, and help to develop provider and patient education.

Our advisors have conducted a three-armed clinical outcome study of cannabidiol (CBD) treatment on Anxiety, Insomnia, and Chronic Pain. Through these study, our medical advisors seek to further educate their peers and patients on the clinical applications for full-spectrum hemp extract and further the advancement of product development for Formula30A. We are continuously grateful for our advisors and appreciate their commitment to excellence in patient care.
