Ingredient Transparency · database check
Full

Every active ingredient lists its own amount on the label.

Why this rating?
  • The label discloses an exact amount for 3 of its 3 active ingredients.
  • No proprietary blends here — you can verify the dose of every single component.

Boswellia Extract by SuperiorLabs contains 3 active ingredients. Indian Frankincense extract (Boswellia serrata) is the main component — this is a traditional resin used to support joint and inflammatory response.

Black Pepper fruit extract is added to the formula; its active compound piperine is often used to help the body absorb other botanicals. L-Leucine is an amino acid also present in the capsule.

The product also contains inactive ingredients: organic rice concentrate and plant cellulose (the capsule material itself).

Does it work?

Moderate evidence
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
Moderate

Some clinical evidence supports this product's ingredients for its stated purpose, but it isn't conclusive.

Why this rating?
  • The label markets this product for: supports healthy joint function and mobility.
  • We looked for evidence on: Knee pain, Osteoarthritis, Rheumatoid arthritis (RA), Pain (chronic), Joint inflammation, Musculoskeletal pain.
  • The strongest evidence on file: Boswellia Serrata is rated "Possibly Effective" for Osteoarthritis (Natural Medicines).
  • Also on file: Boswellia Serrata is rated "Insufficient Reliable Evidence To Rate" for Rheumatoid arthritis (RA), Knee pain.
  • Also on file: Black Pepper is rated "Insufficient Reliable Evidence To Rate" for Pain (chronic), Rheumatoid arthritis (RA).

Boswellia serrata is rated as possibly effective for osteoarthritis — there is some clinical evidence it may help with joint symptoms. For other uses listed on the label — allergic rhinitis (hay fever), Alzheimer disease, asthma, and cluster headache — the evidence is insufficient to rate either way.

Black Pepper and L-Leucine effectiveness ratings are not on file in our data.

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 2 of the 2 matched ingredients.
  • Pregnancy & breastfeeding safety ratings cover 2 of 2.
  • General safety write-ups exist for 2 of 2.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

Boswellia serrata is generally well tolerated in the short term when taken orally, though quality and dose vary widely between products. The most common side effects are abdominal pain, diarrhea, headache, heartburn, itching, and nausea.

In rare cases, large amounts have caused bezoar formation (a blockage in the digestive tract). Black Pepper is generally well tolerated in food amounts or as a single dose, with common side effects being a burning aftertaste, indigestion, and reduced taste perception.

A rare allergic reaction is possible in sensitive people. For pregnancy: the data on Boswellia serrata advises against use — there isn't enough safety information.

For breastfeeding, the data advises against it as well. Black Pepper is rated as likely safe in pregnancy and likely safe during breastfeeding.

Safety data is not on file for L-Leucine.

The most serious documented interaction for these ingredients is Moderate. Check your medications for a personalized result.

Why this rating?
  • 2 of the 2 matched ingredients can interact with medications — Boswellia Serrata, Black Pepper.
  • The most serious interaction on file is rated Moderate.
  • Some involve high-stakes drug classes: anticoagulant / antiplatelet drugs; immunosuppressants / transplant drugs; diabetes medications; lithium.
  • For scale: 1,139 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.

Check these medication types before using this product, worst severity first: seizure medications (phenytoin), heart and blood pressure drugs (propranolol), antibiotics (rifampin), HIV medications (nevirapine), asthma medications (theophylline), cholesterol medications (atorvastatin), immunosuppressants, sedatives (pentobarbital), and any medication processed by your liver enzymes (CYP2D6, CYP2C19, CYP1A2, CYP2C9, or CYP3A4). If you're uncertain whether your drugs fall into these categories, ask your pharmacist.

The bottom line

Scorecard at a glanceFully disclosed formula with some supporting evidence for its stated purpose. Moderate medication interactions have been identified, and safety information is well characterized.

This product is most studied for osteoarthritis, though the evidence is modest. If you take any seizure medication, heart drug, blood thinner, immunosuppressant, or any medication broken down by your liver, you need to check your exact prescriptions with your pharmacist before starting — the interaction risk is real.

Pregnant or breastfeeding? Boswellia isn't recommended.

Talk with your pharmacist if you're on any regular medication.

Black Pepper fruit 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.

Theoretically, Boswellia serrata might increase the levels of CYP2C9 substrates.
In vitro research shows that Boswellia serrata gum resin inhibits CYP2C9 enzymes.

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

Theoretically, Boswellia serrata might increase the levels of CYP2D6 substrates.
In vitro research shows that Boswellia serrata gum resin inhibits CYP2D6 enzymes.

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

Theoretically, Boswellia serrata might increase or decrease the levels and clinical effects of CYP3A4 substrates.
In vitro research shows that Boswellia serrata gum resin inhibits CYP3A4 enzymes. Other in vitro research shows that Boswellia serrata extract inhibits CYP3A4 enzymes at most concentrations, although it may modestly induce enzyme activity at low concentrations.

Likelihood Possible Evidence D
Immunosuppressants

Theoretically, Boswellia serrata might alter the effects of immunosuppressive drugs.
Some in vitro research suggests that Boswellia serrata extracts might inhibit mediators of autoimmune disorders such as leukotrienes and reduce production of antibodies and cell-mediated immunity. However, other in vitro research suggests that, when coupled with calcium ions, boswellic acids containing the keto group have immunostimulant properties within specific cell signaling pathways.
