Immunity relies on the balance between cellular energy , antioxidant defense , and micronutrient availability . Shilajit, rich in fulvic acid, DBPs/DCPs, and minerals, is being studied as an indirect immune system support . This guide discusses the evidence, its limitations, and practical implications.
Note: Shilajit is a phytocomplex : its activity results from a synergy (humic/fulvic acids, DBPs/DCPs, minerals), not from a single isolated molecule.
1) Shilajit, oxidative stress and immunity
1.1 Chronic oxidative stress impairs immune signaling (cytokine imbalance, mitochondrial dysfunction). Shilajit compounds act on several levels: free radical scavenging , redox modulation, and maintenance of energy homeostasis.
1.2 Fulvic acid: immuno-redox
Fulvic acid can modulate immunity and cellular oxidative status; the 2018 review summarizes these effects (immunomodulation, gastrointestinal barrier, redox). Mainly preclinical and observational evidence; dedicated trials are still needed.
Scientific point: Fulvic acid acts as an electron donor/acceptor depending on the cellular redox context, which may explain sometimes divergent results in the literature.
1.3 DBPs/DCPs: mito-protectors
Dibenzo-α-pyrones (DBPs/DCPs) present in shilajit are described as cellular bioenergy supports and major components of the phytocomplex.
2) Minerals and immune support
2.1 Shilajit contains multiple minerals and trace elements (zinc, iron, selenium, etc.) involved in immune function: antioxidant enzymes (GPx), lymphocyte proliferation, healing.
Tip: Favor
standardized and purified extracts publishing a batch
COA : mineral profiles + contaminant screening.
3) Preclinical studies on immunity
3.1 “Chronic fatigue” animal model
In rats, shilajit normalized the HPA response and preserved mitochondrial function with impact on fatigue-related behaviors—mechanisms relevant to immune resilience under stress.
3.2 CHD-FA (fulvic derivative) and infected wounds
In an infected wound model (MRSA / P. aeruginosa), the application of CHD-FA reduces the bacterial load and accelerates healing (antimicrobial + anti-inflammatory effects). Human transferability: to be confirmed.
4) Indirect human data
4.1 To date, there have been no clinical trials directly measuring “immunity” under shilajit (e.g., incidence of infections). However, useful signals exist:
-
Muscle recovery/performance (8 weeks, 500 mg/day, trained subjects): better strength retention after fatigue protocol, reduction of collagen degradation markers.
Critical reading: These results support overall bioenergetic support (mitochondria, connective tissue) that may improve general resistance , but do not constitute evidence of an anti-infectious effect.
5) Comparison with other adaptogens
5.1 Ginseng (Panax ginseng) : abundant literature showing immunomodulatory effects (innate/adaptive) and better resistance to infections; recent reviews confirm this position.
5.2 Rhodiola : indirect effects via reduction of stress and fatigue, beneficial for the neuro-immuno-endocrine axis.
5.3 Shilajit positioning : indirect support — mainly through antioxidants (fulvic acid, phenolics), mitochondria (DBPs) and minerals .
6) Security and regulatory framework
6.1 Purity : Choose purified and certified products (COA) to avoid contamination; surveys on Ayurvedic products have found heavy metals (Pb, Hg, As) beyond tolerable thresholds.
6.2 European Union : strict compliance with Regulation (EU) 2023/915 (maximum levels of contaminants); no “immunity” health claim is authorized for shilajit.
Caution: Avoid untraceable products without recent batch analyses. For people undergoing treatment, pregnant/breastfeeding women, or those with kidney failure: seek prior medical advice.
7) Practical advice
7.1 Forms & Use
Powder, capsules, resin, standardized liquids. Take with water/meal. Start low, increase gradually. Follow the label.
7.2 Purchasing criteria
- Gentle extraction, documented purification (absence of residual solvents/PAH).
- Batch COA: heavy metals, pesticides, mycotoxins, microbiology.
- Standardization (fulvic acid/DBPs) + transparency of methods.
Tip: Request a COA explicitly mentioning the limits of Regulation (EU) 2023/915 for Pb, Cd, Hg, As and mycotoxins (if applicable).

9) FAQ
No, strictly speaking. Direct evidence (infection prevention) is lacking. Shilajit acts rather indirectly : antioxidants , mitochondrial support , mineral intake , which can improve general resilience .
Reviews: Proposed immunomodulatory and redox effects, especially in preclinical settings. Need for dedicated clinical trials to conclude on anti-infectious defense.
Requires a lot COA (heavy metals, solvents, pesticides, mycotoxins, microbiology), a clear purification process, and standardization (fulvic acid/DBPs). Avoids products without traceability.
Yes, typically with ginseng (better documented immunomodulation) or rhodiola (stress/fatigue). Check the interactions and adapt according to your context.
No "immunity" health claims allowed for shilajit. Contaminant controls according to Regulation (EU) 2023/915 . Follows label doses.
Pregnancy/breastfeeding, kidney disease, polymedication (anticoagulants, immunosuppressants), autoimmune conditions: medical advice recommended before taking any medication.
10) Conclusion
Shilajit is not a direct immune stimulant. However, its biochemical properties— immuno-redox (fulvic acid), mitochondrial bioenergetics (DBPs/DCPs), and essential minerals —support overall resilience useful for maintaining defenses. Current evidence is mostly preclinical or indirect (recovery/performance). Recommended positioning: bioenergetic support in an integrative approach, with purity requirements and compliance with the European regulatory framework .
