Acidic Phytocannabinoids as Potential ECS Vitamers: A Formal Nutritional Hypothesis Requiring Clinical Validation

This manuscript advances a formal nutritional hypothesis proposing that acidic phytocannabinoids (e.g., THCA, CBDA, CBGA) may function as conditional endocannabinoid system (ECS)–supportive micronutrients, provisionally termed “ECS vitamers.” The endocannabinoid system plays a central role in maintaining physiological homeostasis, and age- and stress-associated declines in ECS tone have been reported. Acidic phytocannabinoids exhibit structural relatedness, lipophilicity, metabolic transformation, antioxidant capacity, and biological activity in ECS-related pathways—characteristics that parallel certain properties of established vitamin families. These similarities do not establish essentiality. Rather, they provide a rationale for structured investigation. This manuscript formalizes a testable framework outlining the criteria, experimental designs, and clinical validation steps required to determine whether acidic phytocannabinoids meet accepted definitions of micronutrients or vitamers.
