Shilajit (mumijo) C
The only study is open-label, without a comparison group: the effect is not proven
Citable fact
«Shilajit (mumijo)» — evidence level C. Dosage: 500 mg/day (250 mg twice a day) — the dose of the only 28-day open-label study in 25 men. There is no independently confirmed dose. Source: PMID 41613504, permanent link to the source in the list below.
How it works
A resinous exudate containing fulvic acids and trace elements. Effects on mitochondrial function and energy metabolism are discussed, but in humans this was tested only in an open-label study without control.
Dosage and intake
500 mg/day (250 mg twice a day) — the dose of the only 28-day open-label study in 25 men. There is no independently confirmed dose.
In the study — two doses of 250 mg per day. There are no other data on the time of intake.
Forms
Resin, powder or capsules. There is no standardization, and the composition depends heavily on the raw material and purification.
What is confirmed
- In an open-label 28-day study, leg press strength, muscle endurance, grip strength and VO2max increased
- The same study noted a reduction in C-reactive protein and a small gain in lean body mass
Adverse effects and limitations
- There are no controlled human studies with placebo and a comparison group: the improvements may be explained by expectancy effects and natural dynamics
- The raw material is often contaminated with heavy metals (lead, arsenic, mercury) — a product with independent testing is needed
- The open-label study was conducted with the participation of the product manufacturer
- Reviews of plant supplements for body composition do not confirm the claimed effects
Interactions
- There are no data on drug interactions; fulvic acids could theoretically affect drug absorption
Who must not use it
- Under 18 years: Not recommended: there are no safety data.
- Pregnancy and lactation: Not recommended: there are no data, and possible heavy metal impurities are especially dangerous.
- kidney disease
- iron deficiency and anemia
- gout
- participation in competitions under doping control
