Title: Shilajit: A Humic Matter Panacea for Cancer

Type of Document: Peer-reviewed journal article

Takeaway: Shilajit has been used for the treatment of hypersensitivity, diabetes, digestive disorder, nervous ailment, tuberculosis, chronic bronchitis, asthma, anemia,eczema, bone fractures, genitourinary ailment and many other diseases. Fulvic acid is the main constituent of Shilajit and along with FA and HA it also contains minerals in ionic form. These minerals are transported to cells and tissues by fulvic acid, which maintains the electric potential of the cells of the body and thus possibly prevents its death, provides longevity and might act as a rejuvenator. It helps in metabolism and energy production in the body. It can also act as a detoxifying agent in the body and can function as an immunomodulator and helps in haematopoiesis.

                      Takeaway: Fulvic acid may help maintain gut health and microbiota.

                      Summary: This study investigated the effects of fulvic acid (FA) on the growth performance, intestinal function, and fecal ammonia excretion of broilers. 0.5% FA addition increased the serum IgA content, amylase, and lipase activities in the jejunum, as well as the lipase activity and mucin 2 content in the ileum. Feeding broilers with 0.15% FA increased the occludin and zonula occluden-1 content in the ileum, elevated intestinal permeability markers such as diamine oxidase, lipopolysaccharide, and D-lactate dehydrogenase, and further enriched functional pathways including nitrogen metabolism and riboflavin metabolism. Also, FA addition (0.15, 0.3, or 0.5%) increased the jejunum mucin 2 content and maintained the relative stability of the cecal microbiota without detrimental changes to the microbiota composition. Importantly, FA addition decreased the fecal ammonia yield on 2, 4, and 5 d of the fecal ammonia determination in a dose-dependent manner and also lowered the urease activity on 1 and 3 d. Therefore, the addition of 0.15% FA was considered the most effective in maintaining the intestinal health and microbial composition of broilers.
