Full

Every active ingredient lists its own amount on the label.

Why this rating?
  • The label discloses an exact amount for 6 of its 6 active ingredients.
  • No proprietary blends here — you can verify the dose of every single component.

This product contains 6 active ingredients: black pepper extract, maca root extract, ginseng root extract, tongkat ali extract, shilajit extract, and safed musli extract. Black pepper provides piperine to support absorption; ginseng and tongkat ali are herbal adaptogens traditionally used for vitality and sexual function; shilajit is a mineral-rich compound from plant matter; maca root and safed musli are plant extracts with traditional uses.

The product also contains cellulose as an inactive ingredient (a capsule filler).

Does it work?

Not established
Evidence for Intended Use · database check
By FDA rules, dietary supplements can’t claim to treat, cure, or prevent disease — so labels speak in careful marketing language. We discern each product’s intended use from its name, label claims, and label statements, then grade the clinical evidence for that use. How these ratings are computed
Not established

The graded evidence we hold for these ingredients covers different conditions than the ones this product is marketed for, so there's no established rating for its stated use.

Why this rating?
  • The label markets this product for: Promotes energy production.
  • We looked for evidence on: Fatigue, Athletic performance, Chronic fatigue syndrome (CFS), Cancer-related fatigue, Stamina, Endurance — and 1 related terms.
  • The closest evidence on file: Eurycoma Longifolia is rated "Possibly Ineffective" for Athletic performance (Natural Medicines).
  • Also on file: Maca is rated "Insufficient Reliable Evidence To Rate" for Athletic performance, Chronic fatigue syndrome (CFS), Fatigue.
  • Also on file: Black Pepper is rated "Insufficient Reliable Evidence To Rate" for Athletic performance, Fatigue.

The evidence for most of these ingredients is insufficient or not yet established. Ginseng shows possibly effective evidence for upper respiratory tract infections (colds, flu-like illnesses).

Tongkat ali is possibly effective for sexual desire. For the other uses studied—maca for anemia, ginseng for anemia and breast cancer, shilajit for Alzheimer's and sexual dysfunction, and safed musli for athletic performance and muscle strength—the data we hold does not support them.

Black pepper's effectiveness for headache, asthma, depression, and other conditions also lacks reliable evidence at present.

The evidence, ingredient by ingredient Black Pepper Maca American Ginseng Eurycoma Longifolia Shilajit Safed Musli

How safe is it?

Well-documented data
Safety Information · database check
Well characterized

Adverse-effect, pregnancy, and general safety data are on file for most of these ingredients.

Why this rating?
  • We hold adverse-effect (side-effect) data for 5 of the 6 matched ingredients.
  • Pregnancy & breastfeeding safety ratings cover 6 of 6.
  • General safety write-ups exist for 6 of 6.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

Black pepper is generally well tolerated in food amounts and single doses; common side effects are minor (burning aftertaste, upset stomach, altered taste). Concentrated piperine supplements warrant caution without medical advice.

Rare allergic reactions are possible. Maca is generally well tolerated as a food but has not been studied long-term in supplement amounts.

Ginseng is generally well tolerated short-term in healthy adults, though headache has been reported; long-term safety and product quality variation are concerns. Tongkat ali is tolerated short-term in studies, but long-term safety is uncertain and it may raise testosterone levels, carrying a risk of acne, insulin resistance, and liver stress if levels rise too high.

Shilajit must be purified and tested to avoid heavy metal contamination; allergy and rare anaphylaxis are documented, as are rare headache and one case of high blood pressure. Safed musli is considered well tolerated in traditional use, but high-quality human safety data are limited.

Major identified

At least one ingredient has a documented Major-severity interaction. Check your medications for a personalized result.

Why this rating?
  • 4 of the 6 matched ingredients can interact with medications — Black Pepper, American Ginseng, Eurycoma Longifolia, Shilajit.
  • The most serious interaction on file is rated Major.
  • Some involve high-stakes drug classes: anticoagulant / antiplatelet drugs; immunosuppressants / transplant drugs; diabetes medications; lithium.
  • For scale: 1,122 individual medications appear in the full list. A big number alone doesn't make a product dangerous — what matters is whether YOUR medication is on it, so run yours through the interaction checker on this page.

Before taking this product, double-check with your doctor or pharmacist if you take any of the following: warfarin or other blood thinners (major risk of reduced effectiveness); propranolol or other beta-blockers; seizure medications like phenytoin; infection treatments such as rifampin or nevirapine; immunosuppressant drugs; antidiabetes medications; monoamine oxidase inhibitors (MAOIs) for depression; or atorvastatin and other statins. No interactions are documented for maca root extract or safed musli extract in our data, but other ingredients carry significant risks with common medications.

The bottom line

Scorecard at a glanceFully disclosed formula with no established evidence rating for its marketed use. Major medication interactions have been identified, and safety information is well characterized.

This product may appeal to someone looking for traditional herbal support for vitality and sexual function, but the evidence for most claims is insufficient. It's not suitable if you take warfarin or other blood thinners, heart medications like propranolol, seizure drugs, certain infections treatments, immune suppressants, antidiabetes medications, or MAOIs—and those are just the most serious interactions.

If you're pregnant or breastfeeding, the safety data for most of these ingredients advise against it. Talk with your own doctor or pharmacist before starting this product, especially if you take any regular medications.

Black Pepper extract17 drug types · 1,019 drugs

Anticoagulant/Antiplatelet Drugs

Theoretically, black pepper might increase the risk of bleeding when taken with antiplatelet or anticoagulant drugs.
In vitro research shows that piperine, a constituent of black pepper, seems to inhibit platelet aggregation. This has not been reported in humans.

Likelihood Possible Evidence D
Antidiabetes Drugs

Theoretically, black pepper might increase the risk of hypoglycemia when taken with antidiabetes drugs.
Animal research shows that piperine, a constituent of black pepper, can reduce blood glucose levels. Monitor blood glucose levels closely. Dose adjustments might be necessary.

Likelihood Possible Evidence D
Atorvastatin (Lipitor)

Theoretically, black pepper might increase blood levels of atorvastatin.
Animal research shows that taking piperine, a constituent of black pepper, 35 mg/kg can increase the maximum serum concentration of atorvastatin three-fold. This has not been reported in humans.

Likelihood Possible Evidence D
Cyclosporine (Neoral, Sandimmune)

Theoretically, black pepper might increase the effects and side effects of cyclosporine.
In vitro research shows that piperine, a constituent of black pepper, increases the bioavailability of cyclosporine. This has not been reported in humans.

Likelihood Possible Evidence D
Cytochrome P450 2D6 (Cyp2D6) Substrates

Theoretically, black pepper might increase levels of drugs metabolized by CYP2D6.
In vitro research suggests that some constituents of black pepper inhibit CYP2D6. This has not been reported in humans.

Likelihood Possible Evidence D
Cytochrome P450 3A4 (Cyp3A4) Substrates

Theoretically, black pepper might increase levels of drugs metabolized by CYP3A4.
In vitro research and pharmacokinetic simulation data suggest that piperine, a constituent of black pepper, as well as the pepper fruit seem to inhibit CYP3A4. This has not been reported in humans.

Likelihood Possible Evidence D
Lithium

Theoretically, black pepper might increase blood levels of lithium due to its diuretic effects. The dose of lithium might need to be reduced.
Black pepper is thought to have diuretic properties.

Likelihood Probable Evidence D
Nevirapine (Viramune)

Black pepper might increase blood levels of nevirapine.
Clinical research shows that piperine, a constituent of black pepper, increases the plasma concentration of nevirapine. However, no adverse effects were observed in this study.

Likelihood Probable Evidence D
P-Glycoprotein Substrates

Theoretically, black pepper might increase levels of P-glycoprotein substrates.
In vitro research shows that piperine, a constituent of black pepper, seems to inhibit P-glycoprotein.

Likelihood Possible Evidence D
Pentobarbital (Nembutal)

Theoretically, black pepper might increase the sedative effects of pentobarbital.
Animal research shows that piperine, a constituent of black pepper, increases pentobarbital-induced sleeping time.

Likelihood Possible Evidence D
Phenytoin (Dilantin)

Black pepper might increase blood levels of phenytoin.
Clinical research shows that piperine, a constituent of black pepper, seems to increase absorption, slow elimination, and increase levels of phenytoin. Taking a single dose of black pepper 1 gram along with phenytoin seems to double the serum concentration of phenytoin. Consuming a soup with black pepper providing piperine 44 mg/200 mL of soup along with phenytoin also seems to increase phenytoin levels when compared with consuming the same soup without black pepper.

Likelihood Possible Evidence B
Propranolol (Inderal)

Black pepper might increase blood levels of propranolol.
Clinical research shows that piperine, a constituent of black pepper, seems to increase absorption and slow elimination of propranolol.

Likelihood Possible Evidence B
Rifampin (Rifadin)

Black pepper might increase blood levels of rifampin.
Clinical research shows that piperine, a constituent of black pepper, seems to increase absorption and serum levels of rifampin.

Likelihood Possible Evidence B
Theophylline

Black pepper might increase blood levels of theophylline.
Clinical research shows that piperine, a constituent of black pepper, seems to increase absorption and slow elimination of theophylline.

Likelihood Possible Evidence D
Amoxicillin (Amoxil, Trimox)

Theoretically, black pepper might increase the effects and side effects of amoxicillin.
Animal research shows that taking piperine, a constituent of black pepper, with amoxicillin increases plasma levels of amoxicillin. This has not been reported in humans.

Likelihood Possible Evidence D
Carbamazepine (Tegretol)

Theoretically, black pepper might increase blood levels of carbamazepine, potentially increasing the effects and side effects of carbamazepine.
One clinical study in patients taking carbamazepine 300 mg or 500 mg twice daily shows that taking a single 20 mg dose of purified piperine, a constituent of black pepper, increases carbamazepine levels. Piperine may increase carbamazepine absorption by increasing blood flow to the GI tract, increasing the surface area of the small intestine, or inhibiting cytochrome P450 3A4 (CYP3A4) in the gut wall. Absorption was significantly increased by 7-10 mcg/mL/hour. The time to eliminate carbamazepine was also increased by 4-8 hours. Although carbamazepine levels were increased, this did not appear to increase side effects. In vitro research also shows that piperine can increase carbamazepine levels by 11% in a time-dependent manner.

Likelihood Possible Evidence B
Cytochrome P450 1A2 (Cyp1A2) Substrates

Theoretically, black pepper might decrease levels and clinical effects of drugs metabolized by CYP1A2.
In vitro research suggests that black pepper induces CYP1A2. This has not been reported in humans.

Likelihood Possible Evidence D
Black Pepper extract full monograph & interactions

Tongkat Ali extract5 drug types · 248 drugs

Propranolol (Inderal)

Eurycoma longifolia can reduce the levels and clinical effects of propranolol.
A small clinical study in healthy persons shows that taking a single dose of a water-based Eurycoma longifolia extract 200 mg, in combination with a single dose of propranolol 80 mg, reduces the propranolol area under the curve (AUC) by 29%, reduces the peak concentration by 42%, and increases time to peak concentration by 86% when compared with control. Since the elimination half-life of propranolol did not change, it seems that Eurycoma longifolia alters the kinetics of propranolol by decreasing its absorption in the gut, and not by altering its metabolism. It is not known if separating administration will prevent this interaction.

Likelihood Probable Evidence A
Cytochrome P450 1A2 (Cyp1A2) Substrates

Theoretically, Eurycoma longifolia might increase levels CYP1A2 substrates.
In vitro research suggests that methanolic Eurycoma longifolia root extract weakly inhibits CYP1A2 enzymes. This effect has not been reported in humans.

Likelihood Possible Evidence D
Cytochrome P450 2A6 (Cyp2A6) Substrates

Theoretically, Eurycoma longifolia might increase levels of CYP2A6 substrates.
In vitro research suggests that methanolic Eurycoma longifolia root extract weakly inhibits CYP2A6 enzymes. This effect has not been reported in humans.

Likelihood Possible Evidence D
Cytochrome P450 2C19 (Cyp2C19) Substrates

Theoretically, Eurycoma longifolia might increase levels of CYP2C19 substrates.
In vitro research suggests that methanolic Eurycoma longifolia root extract weakly inhibits CYP2C19 enzymes. This effect has not been reported in humans.

Likelihood Possible Evidence D
Testosterone

Theoretically, Eurycoma longifolia may further increase levels of testosterone.
A clinical study in aging males with testosterone levels below 300 ng/dL shows that taking a specific water extract of Eurycoma longifolia roots (Physta; Biotropics Malaysia) 100-200 mg daily with breakfast for 12 weeks increases total testosterone levels by 8% to 11% when compared with placebo. It is unclear whether this increase would occur in individuals with normal testosterone levels.

Likelihood Possible Evidence D
Tongkat Ali extract full monograph & interactions

Ginseng root extract4 drug types · 217 drugs

Warfarin (Coumadin)

American ginseng seems to decrease the effectiveness of warfarin therapy.
Healthy patients receiving warfarin 5 mg daily, who also take American ginseng 1 gram twice daily, seem to have a significantly reduced international normalized ratio (INR).

Likelihood Likely Evidence B
Antidiabetes Drugs

Theoretically, taking American ginseng with antidiabetes drugs might increase the risk of hypoglycemia.
American ginseng seems to lower postprandial blood glucose. Theoretically, concomitant use with antidiabetes drugs might enhance blood glucose lowering effects and possibly cause hypoglycemia.

Likelihood Probable Evidence B
Immunosuppressants

Theoretically, American ginseng use might interfere with immunosuppressive therapy.
American ginseng seems to stimulate immune function. Theoretically, American ginseng might decrease the effectiveness of immunosuppressant drugs.

Likelihood Possible Evidence D
Monoamine Oxidase Inhibitors (Maois)

Theoretically, American ginseng can interfere with MAOI therapy.
There is one case report of insomnia, headache, and tremors when an unspecified ginseng product was used with phenelzine (Nardil), an MAOI. There is also one case report of hypomania when an unspecified ginseng product was used with phenelzine. Theoretically, American ginseng may interfere with MAOI therapy.

Likelihood Possible Evidence D

Shilajit Extract1 drug type · 86 drugs

Antidiabetes Drugs

Taking shilajit with antidiabetes drugs might increase the risk of hypoglycemia.
Most human and animal research shows that shilajit can decrease fasting plasma glucose levels. In an animal model, shilajit 100 mg per kg daily enhanced the glucose-lowering ability of both glibenclamide and metformin when given in combination over a 4 week period. Monitor blood glucose levels closely. Dose adjustments might be necessary.

Shilajit Complex 1420 mg by Vitamatic: Common Questions

Does Shilajit Complex 1420 mg by Vitamatic interact with any medications?
Yes. Based on its ingredients, Shilajit Complex 1420 mg has a known interaction with 1,121 medications, including 2 rated major. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Shilajit Complex 1420 mg contains 6 active ingredients, and an interaction can come from any of them. We check every ingredient, combine the results into one list per medication, and show which ingredient and mechanism is responsible.
Where does this information come from?
The product label data comes from the NIH Dietary Supplement Label Database (DSLD); the interaction data is built on the Natural Medicines database and reviewed by HelloPharmacist pharmacists.
Does this product contain anything besides shilajit?
Yes—this is a blend of six active ingredients: shilajit, black pepper, maca root, ginseng, tongkat ali, and safed musli extract. The combination is designed to work synergistically, though each has its own traditional uses and studied effects.
Is it safe to take this if I'm pregnant?
No. Black pepper is likely safe in pregnancy, but maca, ginseng, tongkat ali, and shilajit all lack sufficient safety data and are advised against during pregnancy. Talk with your doctor or pharmacist before considering it.
Can I take this while breastfeeding?
It's not recommended. Black pepper is likely safe while breastfeeding, but maca, ginseng, tongkat ali, shilajit, and safed musli all have either unknown or insufficient safety information while nursing. Discuss with your doctor or pharmacist for personalized advice.
Does shilajit in this product contain heavy metals?
We can't guarantee it—that depends on the brand's purification and testing. Our data notes that unpurified shilajit products may contain heavy metals or contaminants, so only use tested, purified brands from reputable makers.
What does ginseng in this product actually do?
Ginseng is possibly effective for upper respiratory infections like colds. For the other uses studied—anemia, breast cancer, sexual dysfunction, and others—we don't yet have reliable evidence in our data that it works.
Is tongkat ali safe to take long-term?
Short-term use in clinical studies is generally tolerated, but long-term safety hasn't been well studied. Also, tongkat ali may raise testosterone levels, which could cause acne, insulin resistance, and liver stress if levels go too high—discuss with your doctor if you plan to take it beyond the short term.
