Every active ingredient lists its own amount on the label.

Why this rating?
  • The label discloses an exact amount for 2 of its 2 active ingredients.
  • No proprietary blends here — you can verify the dose of every single component.

This product has 2 active ingredients. Alpha-GPC (600 mg per capsule) is a compound that may support brain function and memory, particularly for Alzheimer disease, though evidence for other cognitive benefits is still being established.

Bioperine is a concentrated extract from black pepper that's added to supplements to boost how your body absorbs nutrients. The capsule also contains inactive ingredients—hypromellose, rice flour, microcrystalline cellulose, and magnesium stearate—which are standard binders and fillers.

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: Cognitive function and athletic performance support.
  • We looked for evidence on: Alzheimer disease, Athletic performance, Cognitive function, Vascular dementia, Memory, Learning — and 1 related terms.
  • The strongest evidence on file: Alpha-gpc is rated "Possibly Effective" for Alzheimer disease (Natural Medicines).
  • Also on file: Black Pepper is rated "Insufficient Reliable Evidence To Rate" for Athletic performance.
  • Also on file: Alpha-gpc is rated "Insufficient Reliable Evidence To Rate" for Cognitive function, Vascular dementia.

Alpha-GPC is possibly effective for Alzheimer disease based on the evidence we hold. For other brain-related uses—including general cognitive function, vascular dementia (reduced blood flow to the brain), and stroke recovery—the evidence isn't established yet.

Bioperine itself doesn't have established effectiveness ratings in our data for any condition; it's included primarily to enhance absorption of other ingredients.

The evidence, ingredient by ingredient Black Pepper Alpha-gpc

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.

Alpha-GPC is generally well tolerated in studies, but long-term safety isn't fully established. Rarely, it's been linked to dizziness, headache, insomnia, and in people who've used it for 2 months or longer, an elevated risk of stroke compared to non-users—talk with your pharmacist or doctor if you're considering longer-term use.

Black pepper (Bioperine) is safe in the amounts found in food, but concentrated piperine supplements should be used cautiously. In studies, it mainly caused mild effects like a burning aftertaste, upset stomach, or reduced taste perception.

Rarely, people sensitive to black pepper or cayenne have had allergic reactions including hives, facial swelling, and difficulty breathing. The data on pregnancy and breastfeeding safety for Alpha-GPC is incomplete; for Bioperine, pregnancy use is considered likely safe, but lactation data are limited.

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 — Black Pepper, Alpha-gpc.
  • 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: 1,030 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 your exact medications before starting, especially: seizure drugs like phenytoin (Dilantin)—blood levels could spike significantly; heart and blood pressure medications like propranolol; HIV drugs such as nevirapine; tuberculosis medications like rifampin; and theophylline for asthma or breathing. Also mention if you use a scopolamine patch (Transderm Scop) for motion sickness, since Alpha-GPC may reduce its effectiveness.

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're exploring support for Alzheimer disease, Alpha-GPC may be worth discussing with your doctor—the evidence is most solid there. Before you start, make absolutely sure you don't take phenytoin, propranolol, an HIV medication, a tuberculosis drug, theophylline, or a scopolamine patch, since Bioperine can change how your body handles these.

If you're on any other medications, check them with a pharmacist first.

Bioperine17 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
Bioperine full monograph & interactions

Alpha-GPC1 drug type · 16 drugs

Scopolamine (Transderm Scop)

Theoretically, alpha-GPC might decrease the effects of scopolamine.
A small clinical study shows that alpha-GPC can partially counteract the attention and memory impairment effects caused by scopolamine given intramuscularly. Whether alpha-GPC can decrease the beneficial anti-motion sickness effects of the scopolamine patch (Transderm Scop) is unclear.

Hyper Absorb Alpha-GPC 600 mg by REVSCI: Common Questions

Does Hyper Absorb Alpha-GPC 600 mg by REVSCI interact with any medications?
Yes. Based on its ingredients, Hyper Absorb Alpha-GPC 600 mg has a known interaction with 1,029 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Hyper Absorb Alpha-GPC 600 mg contains 2 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.
Is Bioperine safe to take every day?
In food amounts, yes—black pepper is safe as a spice. But concentrated Bioperine supplements haven't been studied long-term, so the data we hold suggests using them cautiously and ideally with your doctor's guidance rather than taking them on your own indefinitely.
What is Alpha-GPC supposed to do?
Alpha-GPC is studied mainly for Alzheimer disease, where evidence suggests it may help—that's the one condition where it's rated possibly effective. For other brain functions like general memory or thinking, the evidence isn't established yet in our data.
Can I take this if I'm pregnant or breastfeeding?
Bioperine (black pepper) is considered likely safe in pregnancy and likely safe while breastfeeding based on the data we hold. But we don't have enough safety information about Alpha-GPC to say either way—talk with your doctor or pharmacist for personalized advice.
What side effects might I notice?
Most people don't report problems. When they do, it's usually mild—a burning aftertaste, upset stomach, or a slight change in taste from the Bioperine. Very rarely, someone sensitive to black pepper could have an allergic reaction. Alpha-GPC rarely causes dizziness, headache, or insomnia.
Does this really boost absorption of other supplements?
Bioperine is added to many products because research shows piperine can increase absorption of certain nutrients, but the evidence we hold doesn't specify how much it helps with Alpha-GPC itself.
Can I take this long-term?
The long-term safety of Alpha-GPC isn't fully established in our data. One note: people who've used Alpha-GPC for 2 months or longer have shown an elevated stroke risk compared to non-users, so that's something to discuss with your doctor if you're thinking about extended use.
