HelloPharmacist Scorecard of BCAA 2:1:1 with BioPerine by Premium Certified
Our pharmacy team’s full take, with four database checks built into the cards below — a summary of what is known, not a grade of the product itself.
What’s inside
Full disclosure
This product has 4 active ingredients: three branched-chain amino acids (BCAAs) — L-leucine, L-isoleucine, and L-valine — plus BioPerine, which is a concentrated extract of black pepper. The amino acids are meant to support muscle recovery and performance, while BioPerine is included to enhance how your body absorbs the other ingredients.
The tablet also contains inactive ingredients: cellulose, dicalcium phosphate, microcrystalline cellulose, stearic acid, magnesium stearate, and silicon dioxide.
Does it work?
Couldn't assess
The evidence doesn't establish how well these BCAAs work. For the conditions listed in our data — hay fever, asthma, athletic performance, headache, depression, and diarrhea — the rating is insufficient reliable evidence for each one.
That means we don't have enough solid research to say whether this product is effective for those uses. Talk with your pharmacist or doctor about what the research actually shows for your specific goal.
How safe is it?
Well-documented data
Black pepper (BioPerine) is generally well tolerated when used in food amounts or as a single medicinal dose. The most common side effects are a burning aftertaste, indigestion (dyspepsia), and reduced taste perception.
Cough can occur if inhaled. Allergic reactions are rare but possible in people sensitive to black pepper or related spices.
For pregnancy, black pepper rates as likely safe — but the data also notes likely unsafe for pregnancy, so there's conflicting information here. For breastfeeding, it's rated likely safe.
Because the pregnancy data are mixed, talk with your doctor or pharmacist before using this during pregnancy. We hold no pregnancy or breastfeeding safety data for the three amino acids.
Meds to double-check
Moderate interaction found
If you take phenytoin (Dilantin) or any seizure medication, check with your pharmacist before starting — black pepper can significantly raise blood levels. Also double-check if you're on propranolol (Inderal), rifampin (Rifadin), nevirapine (Viramune), cyclosporine (Neoral, Sandimmune), atorvastatin (Lipitor), theophylline, or pentobarbital (Nembutal) — all are affected by the BioPerine in this product.
The bottom line
Scorecard at a glanceFully disclosed formula with no assessable stated purpose. Moderate medication interactions have been identified, and safety information is well characterized.
This product is mainly for people looking to support muscle recovery with BCAAs, but evidence for its effectiveness isn't established in our data. If you take seizure medications, heart medications, antibiotics, antivirals, immunosuppressants, statins, or asthma drugs, you need to check with your pharmacist first — black pepper extract can change how your body handles these.
Otherwise, it's generally well tolerated.

BioPerine
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
