HelloPharmacist Scorecard of Citrus Bergamot Complex 1,000 mg by eleva NUTRITION
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 formula has four ingredients: Citrus Bioflavonoid Complex, Black Pepper Powder, Citrus Bergamot Powder, and Citrus Bergamot Fruit Extract, plus methylcellulose as an inactive capsule ingredient. Black pepper contains piperine, which is the compound responsible for most of the documented interactions.
The two bergamot components—the powder and the fruit extract—come from the same plant and carry the same safety and interaction profile. We couldn't check the bioflavonoid complex for interactions.
Does it work?
Moderate evidence
The bergamot components (both the powder and the fruit extract) are rated Possibly Effective for high cholesterol (hyperlipidemia). They're rated Possibly Ineffective for mental alertness.
For nonalcoholic fatty liver disease and autism spectrum disorder, there isn't enough evidence in our data to rate them. The evidence for black pepper's effectiveness for headache, depression, hay fever (allergic rhinitis), asthma, or athletic performance is insufficient to rate.
How safe is it?
Well-documented data
Black pepper from food or in medicine-strength single doses is generally well tolerated. Most side effects are mild: burning aftertaste, indigestion, and reduced taste perception.
Allergic reactions are rare but possible. Cough has been reported when inhaled.
Bergamot extract taken orally appears well tolerated short-term, though one case of heartburn was reported in clinical trials. The safety data advises against bergamot supplements during pregnancy and breastfeeding because there isn't enough safety information.
Don't rely on bergamot essential oil—it can be toxic if swallowed and causes sun-related skin reactions when applied to skin.
Meds to double-check
Moderate interaction found
Check with your pharmacist or doctor before taking this if you're on propranolol or other heart medications, seizure drugs like phenytoin, antibiotics such as rifampin, theophylline (for breathing), antidiabetes medications, or any photosensitizing drugs. Black pepper may raise blood levels of these drugs, and bergamot may increase low-blood-sugar risk.
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.
If you take heart, seizure, antibiotic, asthma, or diabetes medications, you should check this product with your pharmacist or doctor before starting. Bergamot isn't recommended in pregnancy or while breastfeeding.
Black pepper at food amounts is generally fine, but concentrated supplements warrant caution.

Citrus Bergamot Complex 1,000 mg by eleva NUTRITION Drug Interactions
HelloPharmacist Interaction Report
Citrus Bergamot Complex by eleva NUTRITION contains black pepper and two forms of bergamot, both of which have documented interactions with medications.
The most serious concern is black pepper: it may increase blood levels of several drugs, including the heart medication propranolol (Inderal), the seizure drug phenytoin (Dilantin), the antibiotic rifampin (Rifadin), theophylline (used for breathing), and others. These are all Moderate-severity interactions.
A single gram of black pepper with phenytoin may double the drug's level in your bloodstream.
Read the full breakdown — every affected drug type, severity by severity
Bergamot (in two forms here) also interacts with antidiabetes drugs—animal research suggests it may lower blood sugar, raising the risk of low blood sugar (hypoglycemia) if you're already taking diabetes medication. Bergamot also theoretically increases risk with photosensitizing drugs (medications that make your skin more sun-sensitive).
Both of these bergamot interactions are Moderate in severity.
We could not check the Citrus Bioflavonoid Complex ingredient. Altogether, these interactions span 1,174 individual medications.

For each ingredient in Citrus Bergamot Complex 1,000 mg with known interactions, here are the types of medications they can affect. Open any type for the detail — or search your exact drug in the checker above.
Citrus Bioflavonoid Complex
Antidiabetes Drugs
Theoretically, concomitant use of quercetin and antidiabetes drugs might increase the risk of hypoglycemia.
Clinical research suggests that a combination of quercetin, myricetin, and chlorogenic acid reduce levels of fasting glucose in patients with type 2 diabetes, including those already taking antidiabetes agents. The effect of quercetin alone is unknown.
Antihypertensive Drugs
Theoretically, taking quercetin with antihypertensive drugs might increase the risk of hypotension.
Quercetin can modestly decrease blood pressure in people with mild hypertension. Theoretically, it might have additive blood pressure lowering effects when used with antihypertensive drugs.
Cyclosporine (Neoral, Sandimmune)
Theoretically, concomitant use might increase the levels and adverse effects of cyclosporine.
A small study in healthy volunteers shows that pretreatment with quercetin increases plasma levels and prolongs the half-life of a single dose of cyclosporine, possibly due to inhibition of p-glycoprotein or cytochrome P450 3A4 (CYP3A4), which metabolizes cyclosporin.
Cytochrome P450 2C8 (Cyp2C8) Substrates
Theoretically, concomitant use might increase the levels and adverse effects of CYP2C8 substrates.
In vitro research shows that quercetin inhibits CYP2C8. Inhibition of paclitaxel (Taxol) metabolism via CYP2C8 has been reported in vitro. However, a small study in humans found no effect of quercetin on rosiglitazone (Avandia), which is also a CYP2C8 substrate.
Cytochrome P450 2C9 (Cyp2C9) Substrates
Theoretically, concomitant use might increase the levels and adverse effects of CYP2C9 substrates.
A small clinical study in healthy volunteers shows that taking quercetin 500 mg twice daily for 10 days prior to taking diclofenac, a CYP2C9 substrate, increases diclofenac plasma levels by 75% and prolongs the half-life by 32.5%. Animal research also shows that pretreatment with quercetin increases plasma levels and prolongs the half-life of losartan (Cozaar), a substrate of CYP2C9. Furthermore, laboratory research shows that quercetin inhibits CYP2C9.
Cytochrome P450 2D6 (Cyp2D6) Substrates
Theoretically, concomitant use might increase the levels and adverse effects of CYP2D6 substrates.
In vitro research show that quercetin inhibits CYP2D6. This effect has not been reported in humans.
Cytochrome P450 3A4 (Cyp3A4) Substrates
Theoretically, concomitant use might alter the effects and adverse effects of CYP3A4 substrates.
A small clinical study in healthy volunteers shows that pretreatment with quercetin increases plasma levels and prolongs the half-life of a single dose of cyclosporine (Neoral, Sandimmune), a substrate of CYP3A4. Animal research also shows that pretreatment with quercetin increases plasma levels and prolongs the half-life of losartan (Cozaar) and quetiapine (Seroquel), substrates of CYP3A4. Other laboratory research also shows that quercetin inhibits CYP3A4. However, one clinical study shows that quercetin can increase the metabolism of midazolam, a substrate of CYP3A4, and decrease serum concentrations of midazolam by about 24% in some healthy individuals, suggesting possible induction of CYP3A4.
Diclofenac (Voltaren, Others)
Theoretically, concomitant use might increase the levels and adverse effects of diclofenac.
A small clinical study in healthy volunteers shows that taking quercetin 500 mg twice daily for 10 days prior to taking diclofenac increases diclofenac plasma levels by 75% and prolongs the half-life by 32.5%. This is thought to be due to inhibition of CYP2C9 by quercetin.
Losartan (Cozaar)
Theoretically, concomitant use might increase the effects and adverse effects of losartan and decrease the effects of its active metabolite.
Animal research shows that pretreatment with quercetin increases plasma levels and prolongs the half-life of losartan (Cozaar) while decreasing plasma levels of losartan's active metabolite. This metabolite, which is around 10-fold more potent than losartan, is the result of cytochrome P450 (CYP) 2C9- and CYP3A4-mediated transformation of losartan. Additionally, in vitro research shows that quercetin may inhibit P-glycoprotein-mediated efflux of losartan from the intestines, resulting in increased absorption of losartan. These results suggest that concomitant use of quercetin and losartan might increase systemic exposure to losartan while also decreasing plasma concentrations of losartan's active and more potent metabolite.
Midazolam (Versed)
Theoretically, concomitant use might decrease the levels and effects of midazolam.
A small clinical study in healthy volunteers shows that quercetin can increase the metabolism of midazolam, with a decrease in AUC of about 24%.
Mitoxantrone
Theoretically, quercetin might increase the effects and adverse effects of mitoxantrone.
In vitro research shows that quercetin increases the intracellular accumulation and cytotoxicity of mitoxantrone, possibly through inhibition of breast cancer resistance protein (BCRP), of which mitoxantrone is a substrate. So far, this interaction has not been reported in humans.
Organic Anion Transporter 1 (Oat1) Substrates
Theoretically, concomitant use might increase the effects and adverse effects of OAT1 substrates.
In vitro research shows that quercetin is a strong non-competitive inhibitor of OAT1, with half-maximal inhibitory concentration (IC50) values less than 10 mcM. So far, this interaction has not been reported in humans.
Organic Anion Transporter 3 (Oat3) Substrates
Theoretically, concomitant use might increase the effects and adverse effects of OAT3 substrates.
In vitro research shows that quercetin is a strong non-competitive inhibitor of OAT3, with half-maximal inhibitory concentration (IC50) values as low as 0.75 mcM. So far, this interaction has not been reported in humans.
Organic Anion-Transporting Polypeptide Substrates (Oatp)
Theoretically, concomitant use might increase the effects and adverse effects of OATP substrates.
In vitro evidence shows that quercetin can inhibit organic anion-transporting peptide (OATP) 1B1-mediated uptake of estrone-3-sulfate and pravastatin. Furthermore, clinical research in healthy males shows that intake of quercetin along with pravastatin increases the AUC of pravastatin by 24%, prolongs its half-life by 14%, and decreases its apparent clearance by 18%, suggesting that quercetin modestly inhibits the uptake of pravastatin in hepatic cells.
P-Glycoprotein Substrates
Theoretically, concomitant use might alter the effects and adverse effects of P-glycoprotein substrates.
There is preliminary evidence that quercetin inhibits the gastrointestinal P-glycoprotein efflux pump, which might increase the bioavailability and serum levels of drugs transported by the pump. A small study in healthy volunteers reported that pretreatment with quercetin increased bioavailability and plasma levels after a single dose of cyclosporine (Neoral, Sandimmune). Also, two small studies have shown that quercetin might decrease the absorption of talinolol, a substrate transported by the gastrointestinal P-glycoprotein efflux pump. However, in another small study, several days of quercetin treatment did not significantly affect the pharmacokinetics of saquinavir (Invirase). The reason for these discrepancies is not entirely clear. Until more is known, use quercetin cautiously in combination with P-glycoprotein substrates.
Pravastatin (Pravachol)
Theoretically, concomitant use might increase the effects and adverse effects of pravastatin.
In vitro evidence shows that quercetin can inhibit OATP 1B1-mediated uptake of pravastatin. Also, preliminary clinical research in healthy males shows that intake of quercetin along with pravastatin increases the maximum concentration of pravastatin by 24%, prolongs its half-life by 14%, and decreases its apparent clearance by 18%, suggesting that quercetin modestly inhibits the uptake of pravastatin in hepatic cells.
Prazosin (Minipress)
Theoretically, quercetin might increase the effects and adverse effects of prazosin.
In vitro research shows that quercetin inhibits the transcellular efflux of prazosin, possibly through inhibition of breast cancer resistance protein (BCRP), of which prazosin is a substrate. BCRP is an ATP-binding cassette efflux transporter in the intestines, kidneys, and liver. So far, this interaction has not been reported in humans.
Quetiapine (Seroquel)
Theoretically, concomitant use might increase the effects and adverse effects of quetiapine.
Animal research shows that pretreatment with quercetin can increase plasma levels of quetiapine and prolong its clearance, possibly due to inhibition of cytochrome P450 3A4 (CYP3A4) by quercetin. Additionally, the brain-to-plasma ratio of quetiapine concentrations increased, possibly due to inhibition of P-glycoprotein at the blood-brain barrier. This interaction has not been reported in humans.
Quinolone Antibiotics
Theoretically, concomitant use might inhibit the effects of quinolone antibiotics.
In vitro, quercetin binds to the DNA gyrase site on bacteria, which may interfere with the activity of quinolone antibiotics.
Sulfasalazine (Azulfidine)
Theoretically, quercetin might increase the effects and adverse effects of sulfasalazine.
Animal research shows that quercetin increases the maximum serum concentration (Cmax) and area under the curve (AUC) of sulfasalazine, possibly through inhibition of breast cancer resistance protein (BCRP), of which sulfasalazine is a substrate. So far, this interaction has not been reported in humans.
Warfarin (Coumadin)
Theoretically, quercetin may increase the risk of bleeding if used with warfarin.
Animal and in vitro studies show that quercetin might increase serum levels of warfarin. Quercetin and warfarin have the same human serum albumin (HSA) binding site, and in vitro research shows that quercetin has stronger affinity for the HSA binding site and can theoretically displace warfarin, causing higher serum levels of warfarin. Animal research shows that taking quercetin for 2 weeks before initiating warfarin increases the maximum serum level of warfarin by 30%, the half-life by 10%, and the overall exposure by 63% when compared with control. Concomitant administration of quercetin and warfarin, without quercetin pre-treatment, also increased these measures, but to a lesser degree. Researchers theorize that inhibition of CYP3A4 by quercetin may explain these effects. So far, this interaction has not been reported in humans.
Black Pepper, Powder
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.
Citrus Bergamot, Powder
Antidiabetes Drugs
Theoretically, taking bergamot with antidiabetes drugs might increase the risk of hypoglycemia.
Animal research suggests that bergamot juice has hypoglycemic effects.
Photosensitizing Drugs
Theoretically, topical bergamot essential oil might increase the risk of side effects when used along with photosensitizing drugs.
Bergamot contains bergapten, which has photosensitizing effects.
