Shilajit

Key Research Papers and Clinical Trials

Current research on shilajit spans several areas, though much of the available evidence comes from animal studies, analytical research, and small clinical trials rather than large-scale human studies.

Analytical and Composition Studies

Recent research has focused heavily on characterizing shilajit's chemical composition. A 2026 study examined the metal composition and molecular weight distribution in shilajit samples, while another analyzed plant-derived phenolic acids across five different regional sources using advanced HPLC-MS/MS techniques. These compositional studies are important for standardization but don't establish clinical effects.

Animal Studies

The most substantial recent animal research involved Awassi lambs, examining how different shilajit concentrations affected productive traits, blood parameters, and biochemical measurements. However, animal studies have significant limitations when extrapolating to human health outcomes.

Preclinical Cancer Research

A systematic review published in 2026 evaluated preclinical evidence for shilajit in cancer treatment. While this represents an attempt to synthesize existing research, systematic reviews of preclinical studies cannot establish clinical efficacy in humans.

Human Clinical Trials

Several small clinical trials have been completed, though detailed results are not provided in the available evidence:

• NCT02026414: Investigated the effects of PrimaVie (a purified shilajit extract) combined with exercise training on human skeletal muscle
• NCT06641596: Examined shilajit's impact on cardiovascular health, fitness, and weight loss during exercise and diet programs
• NCT02794454: Evaluated shilajit-containing products on male sexual health
• Multiple glucose control studies: At least two trials (NCT05887050, NCT05573607) tested shilajit-containing supplements on glucose control markers

Research Limitations

The available evidence has several important limitations. Most studies are either animal research, analytical/compositional work, or small clinical trials without published results readily available. The clinical trials appear to focus on combination products rather than shilajit alone, making it difficult to isolate shilajit's specific effects. Sample sizes and study designs are not detailed in the available evidence.
