Rating (out of 5): 2

Fulvic acid has a long history of use in traditional medicine systems, such as Ayurveda, where it is a key component of shilajit—a natural substance believed to boost overall immunity and resilience against infections. Its use for colds and viral infections is primarily based on these traditional practices rather than robust scientific validation. Historically, fulvic acid is valued for its purported ability to enhance nutrient absorption and support detoxification, which are thought to strengthen the body’s natural defenses.

Modern scientific research on fulvic acid is limited but growing. Some in vitro (test tube) and animal studies have indicated that fulvic acid may possess antiviral properties, possibly by inhibiting viral replication or enhancing immune activity. For example, a few small studies have demonstrated that fulvic acid can interfere with the replication of certain viruses, such as herpes simplex and influenza, but these findings have not been widely replicated or confirmed in human clinical trials. There are currently no large, well-controlled studies demonstrating that fulvic acid supplementation can effectively prevent or treat the common cold or other viral respiratory infections in humans.

In summary, while there is a traditional basis for the use of fulvic acid to support immune function and fight viral infections like colds, current scientific evidence is preliminary and insufficient to fully validate its efficacy for this purpose. Thus, fulvic acid’s use for colds is primarily supported by tradition, with limited and low-quality scientific backing.
