Unveiling Fulvic Acid: A Review of Its Pharmacological Properties and Health Implications

Fulvic acid (FA), a naturally occurring humic chemical, has a wide range of pharmacological and physiological properties that have uses in human health, animal nutrition, agriculture, and environmental management. Preclinical and clinical studies show that it has antioxidant, anti-inflammatory, antimicrobial, anti-obesity, and immunemodulating properties, as well as the potential to treat chronic inflammatory disorders, type 2 diabetes, and neurodegenerative ailments like Alzheimer's disease. FA has been demonstrated to slow the progression of breast cancer in MCF-7 cell line models, improve skin health beyond lubricants alone, and give antidiarrheal properties. In animal husbandry, FA promotes growth, digestion, egg quality, and immunological responses in chicken, increases disease resistance in shrimp and fish aquaculture, and supports gut micro biome alteration. FA improves soil fertility in agriculture by chelating, transporting nutrients, and regulating pH, and it has the potential to be a long-term weed management technique in rice cultivation. Toxicological studies, including a 90-day oral trial in Wistar rats, have confirmed a high safety margin with a NOAEL of 2,000 mg/kg/day. Collectively, our data emphasize FA's multifunctional potential as a natural, sustainable agent for health promotion, productivity increase, and environmental stewardship, while emphasizing the importance of standardized preparations and additional clinical validation.
