Shilajit and Blood Pressure Medications (Ramipril, Enalapril, Lisinopril)
Leila WehrhahnUpdated:Key points at a glance:
Shilajit may influence blood pressure and could potentially enhance the blood pressure–lowering effects of ACE inhibitors such as ramipril, enalapril and lisinopril. Possible mechanisms discussed in the scientific literature include effects involving nitric oxide (NO) and vascular endothelial function, although the available evidence is limited. Reported issues in this context may include dizziness, feeling faint on standing (orthostatic symptoms) and, less commonly, low blood pressure. The likelihood of such effects may be higher with higher doses, the use of several blood pressure medicines at the same time, and dehydration. Anyone considering taking shilajit alongside prescription blood pressure medication should discuss this with a doctor in advance, start with a low dose, separate the timing of intake, and monitor blood pressure closely during the first two weeks. Shilajit should only be used in the form of products that have been appropriately quality-checked.
Shilajit is a mineral-rich, resin-like substance from the Himalayas that has been used for centuries in Ayurvedic practice. In Europe, shilajit is available as a food supplement and is mainly discussed in relation to its antioxidant and adaptogenic properties. At the same time, ACE inhibitors such as ramipril, enalapril and lisinopril are among the most commonly prescribed blood pressure medicines. This article outlines how shilajit could potentially interact with ACE inhibitors, what evidence is available, how the level of risk might be viewed, and how to approach use as safely as possible.

Shilajit could theoretically enhance the blood pressure‑lowering effects of ACE inhibitors. Evidence is limited; therefore, cautious dosing and close blood pressure monitoring are advisable.
Warum ist diese Kombination relevant?
ACE inhibitors lower blood pressure partly by inhibiting angiotensin II and increasing bradykinin, which leads to vasodilation. Typical adverse effects include dizziness, postural (orthostatic) symptoms and, in some cases, low blood pressure – particularly at the start of treatment or when combined with other substances that may lower blood pressure (4, 5).
Mechanism of the potential interaction
Shilajit contains, among other components, fulvic acids and dibenzo‑α‑pyrone derivatives. Small clinical studies have reported effects on vascular and inflammatory markers, including an apparent improvement in endothelial function and an increase in nitric oxide (NO) markers (2). NO is an important mediator of vasodilation; higher NO activity is generally associated with lower vascular resistance. ACE inhibitors likewise increase NO‑mediated vasodilation via bradykinin. Together, this suggests a biologically plausible additive blood pressure‑lowering effect (4, 5).
At the same time, an older human study using 2 g shilajit per day for 45 days reported no significant change in blood pressure in healthy volunteers, although lipid and antioxidant markers appeared to improve (1). This indicates that shilajit on its own does not necessarily lower blood pressure, but that, in theory, combining it with ACE inhibitors might be more likely to be associated with circulatory symptoms – particularly at the start or at higher doses.

Question 1 of 8
Shilajit may have NO‑related vascular effects; ACE inhibitors also influence NO signalling. Additive vasodilation is biologically plausible, but not firmly established in clinical studies.

Clinical evidence: What is known?
- Small RCT in type 2 diabetes: 12 weeks of shilajit (2×250 mg/day) were associated with improved markers of endothelial function and higher NO biomarkers compared with placebo; blood pressure data were not a primary endpoint (2).
- Study in healthy subjects: 45 days of shilajit (2 g/day) did not show changes in blood pressure; lipid profile and antioxidant status appeared to improve (1).
- ACE inhibitors: Low blood pressure and dizziness are recognised adverse effects, especially when ACE inhibitors are used together with other vasodilatory agents (4, 5).
- Safety aspects: Authorities have warned about potential heavy metal contamination in some Ayurvedic products; using purified, tested products is important (6).
There are no direct studies on the combination “shilajit + ACE inhibitor”. The assessment therefore relies on mechanisms, indirect evidence and known safety profiles.
Risk assessment
- Severity: Moderate – mainly orthostatic symptoms (dizziness on standing), tiredness; symptomatic low blood pressure is considered possible but not well documented (4, 5).
- Likelihood: Low to moderate – depending on individual sensitivity, dose, hydration status and the number of other antihypertensive medicines taken. Individual studies with shilajit alone do not show consistent blood pressure‑lowering effects (1, 2).
- Higher‑risk groups: older people; individuals with already borderline low blood pressure; those on multiple medicines (for example ACE inhibitor + diuretic); people with dehydration; those with autonomic dysfunction.
- Product quality: Insufficiently purified shilajit products may contain heavy metals; this may increase the potential risk of kidney burden – relevant because kidney function and potassium are usually monitored in people taking ACE inhibitors (6).
Main potential risks are dizziness and orthostatic symptoms. Overall likelihood appears low to moderate, but may increase with higher doses, multiple antihypertensives and poor hydration.
Practical recommendations for concurrent use
- Discuss with a doctor: Talk to your prescribing doctor if you are considering taking shilajit while using ramipril, enalapril or lisinopril.
- Start low: If your doctor agrees, begin with the lowest available dose (for example 250 mg/day) and do not increase without medical advice. Pay attention to your individual tolerance (1, 2).
- Separate the timing: Take shilajit at a different time of day from your ACE inhibitor (for example ACE inhibitor in the morning, shilajit in the early afternoon). This can make it easier to attribute any effects and may help to avoid sudden changes in blood pressure.
-
Monitoring in the first 2 weeks:
- Measure blood pressure daily, both seated and 1–3 minutes after standing up.
- Contact your doctor promptly if you notice persistently low readings (for example systolic BP below 100 mmHg), fainting, marked dizziness, palpitations or confusion.
- Hydration and standing up: Stay well hydrated, stand up slowly, and consider compression stockings if you are prone to orthostatic symptoms.
- Check kidney function/potassium: Keep to your routine blood tests while on ACE inhibitors (creatinine, eGFR, potassium). If new symptoms occur, speak to your doctor about whether earlier checks are needed (4).
- Ensure product quality: Choose purified, certified and tested shilajit products (for example with a certificate of analysis or third‑party testing); avoid unclear sources because of the risk of heavy metals (6). More on side effects: Shilajit side effects.
- When to avoid? If your blood pressure control is unstable, you experience pronounced orthostatic symptoms, have advanced kidney impairment, are pregnant or breastfeeding, or are taking several blood pressure‑lowering medicines, shilajit should not be started without medical assessment.
Before starting, seek medical advice, use low doses, separate intake times, monitor blood pressure closely for 1–2 weeks and choose only tested products.
Tabular overview: Possible interactions and measures
| Aspect | Possible effect | Mechanism/basis | Practical measure |
|---|---|---|---|
| Blood pressure | Increased lowering, orthostatic symptoms | NO/endothelial effects of shilajit; ACE inhibitors increase bradykinin/NO (2, 4) | Start with a low dose, separate intake, monitor BP closely for 1–2 weeks |
| Kidney/potassium | Additional strain possible (indirect) | Product quality (heavy metals) relevant; ACE inhibitors already require laboratory monitoring (4, 6) | Use only tested products; attend blood tests as advised by your doctor |
| Side effects | Dizziness, tiredness, gastrointestinal complaints | Vasodilation/orthostatic effects; individual tolerance | If symptoms occur, do not increase the dose, consider stopping and consult a doctor |
Conclusion
The combination of shilajit and ACE inhibitors is theoretically associated with risk, mainly in terms of potentially additive blood pressure‑lowering effects and orthostatic symptoms. Robust clinical data on the combination are lacking; individual studies suggest vascular and NO‑related effects of shilajit but do not show consistent blood pressure changes. Anyone who, after medical consultation, chooses to use shilajit alongside an ACE inhibitor should use a low dose, separate the timing of intake, monitor blood pressure closely and rely exclusively on tested products. This approach may help to balance potential risks and perceived benefits as carefully as possible.
