Your first and best source of information is your medical provider. Products in the CBD market that are currently available vary greatly in their formulations, extraction processes, delivery methods, additional ingredients, and potency testing. Further complicating matters, different "classes" of cannabinoid formulations - isolate, broad spectrum, and full spectrum - have been demonstrated differences in overall product efficacy.
Formula30A CBD contains 25mg of solvent-free, full spectrum cannabinoid extract with organic coconut oil in vegan capsules. Based on anecdotal reports from medical providers recommending Formula30A in the practices, as well as Formula30A's recently completed observational studies, one (1) daily 25mg capsule of Formula30A CBD is the suggested starting dosage for most patients. However, as the endocannabinoid system affects interactions throughout the body, it is strongly recommended that you consult your physician before taking CBD supplements.
