Shilajit has a long history of use in traditional Ayurvedic medicine and other traditional systems, where it is considered a rasayana (rejuvenative) substance. In Ayurveda, it is believed to support overall vitality, including renal (kidney) health, by promoting detoxification and helping to balance the body’s doshas. The use of Shilajit for kidney support is primarily justified by these traditional texts and practices, where it is sometimes recommended for urinary tract health and as an adjunct in managing kidney stones and promoting diuresis.

Scientific research on Shilajit’s effects specifically on kidney health is limited and largely preclinical. Some animal studies suggest antioxidant and anti-inflammatory effects, which could theoretically be beneficial for protecting renal tissue or mitigating oxidative stress-related kidney damage. However, robust clinical studies in humans are lacking, and there is insufficient direct scientific evidence to validate its use for kidney health or kidney disease prevention. Most clinical research on Shilajit focuses on its effects on energy, fatigue, and male reproductive health rather than the renal system. Some concerns have also been raised about potential contamination of Shilajit supplements with heavy metals, which could pose a risk to kidney function.

In summary, Shilajit’s use for kidney support is primarily based on traditional use rather than scientific validation, and the quality of evidence is low.
