HelloPharmacist Scorecard of GO2 Max by HTLT
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
GO2 Max contains 6 active ingredients. Vitamin B12 supports nerve health and energy; black pepper fruit extract provides piperine, a compound that may enhance nutrient absorption; and sodium nitrate contributes electrolyte balance.
The product also includes nicotinamide mononucleotide, vitamin B9, and ElevATP, each playing a role in cellular energy and metabolism. Three inactive ingredients—hypromellose, silicon dioxide, and magnesium stearate—are excipients that help form and stabilize the capsule.
Does it work?
Leans against
The evidence for GO2 Max's ingredients is mixed. Vitamin B12 is effective for B12 deficiency and certain neurological conditions, and likely effective for cyanide poisoning; it's possibly effective for canker sores and nerve pain after shingles.
For black pepper fruit extract, the evidence isn't established—claims about hay fever, asthma, athletic performance, headache, depression, and diarrhea lack reliable data to rate. Sodium nitrate is likely effective for cystic fibrosis and possibly effective for amphotericin B-related kidney damage, but evidence for heart failure and bipolar disorder is insufficient.
We hold no effectiveness data for nicotinamide mononucleotide, vitamin B9, or ElevATP in this product.
How safe is it?
Well-documented data
Vitamin B12 is generally very safe and well tolerated—excess is removed in the urine. Allergic reactions are rare but possible, and severe low potassium (hypokalemia) has been rarely linked to B12 correction of certain anemias.
Black pepper is well tolerated in food amounts and as a single dose; the most common side effects are burning aftertaste, upset stomach, and reduced taste perception. Allergic reactions are rare but can occur in sensitive people.
Sodium nitrate is well tolerated in moderate amounts, but too much can worsen heart disease, high blood pressure, and kidney disease. We hold no pregnancy or breastfeeding data for nicotinamide mononucleotide, vitamin B9, or ElevATP.
Vitamin B12 is likely safe in pregnancy and during breastfeeding at normal recommended amounts—follow your provider's guidance. Black pepper is likely safe in pregnancy and breastfeeding at dietary amounts, though there is one safety rating listing it as possibly unsafe in pregnancy; stick with food amounts and talk to your doctor.
Sodium's safety in pregnancy and breastfeeding is likely safe at normal dietary intake, but possibly unsafe if overconsumed.
Meds to double-check
Moderate interaction found
Before taking GO2 Max, check with your doctor or pharmacist if you take seizure medications (especially phenytoin), blood pressure drugs, heart rhythm medications, diabetic medications like metformin, lithium, corticosteroids, blood thinners, or medications for infections, immunosuppression, cholesterol, or breathing problems. The black pepper in this product may raise blood levels of several of these, and the sodium content can interfere with blood pressure control and electrolyte balance.
The bottom line
Scorecard at a glanceFully disclosed formula with graded evidence leaning against its stated purpose. Moderate medication interactions have been identified, and safety information is well characterized.
GO2 Max may appeal to people looking to support energy and B12 levels, but it's not right for everyone. If you take medication for seizures, heart rhythm, blood pressure, infections, immunosuppression, cholesterol, breathing problems, diabetes, or mood disorders, or if you use lithium or corticosteroids, check with your own doctor or pharmacist before starting—this product could change how those drugs work.
Anyone on blood pressure or seizure medication should be especially cautious.

GO2 Max by HTLT Drug Interactions
HelloPharmacist Interaction Report
GO2 Max by HTLT contains several ingredients with documented medication interactions.
The most serious concern comes through its black pepper fruit extract, which may increase blood levels of seizure medications like phenytoin (Dilantin)—a moderate-severity interaction that could affect how well seizures are controlled. Through its vitamin B12, black pepper fruit extract, and sodium nitrate content, this product interacts with a range of medications across multiple categories.
Read the full breakdown — every affected drug type, severity by severity
Black pepper's active compound, piperine, may raise blood levels of several drugs used for heart rhythm (propranolol), blood pressure, infections (nevirapine, rifampin), immunosuppression (cyclosporine), sleep (pentobarbital), cholesterol (atorvastatin), and breathing problems (theophylline)—all moderate interactions. Vitamin B12 has one minor interaction: metformin, a diabetes medication, may lower B12 levels over time.
Sodium nitrate interacts with blood pressure drugs, corticosteroids, lithium, and several other sodium-related medications, raising the risk of imbalanced sodium levels (hypernatremia).
We could not check three of this product's ingredients—nicotinamide mononucleotide, vitamin B9, and ElevATP—because we hold no interaction data for them. Altogether, these interactions span 1,151 individual medications.

For each ingredient in GO2 Max 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.
Black Pepper Fruit Extract
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.
Sodium
Antihypertensive Drugs
Theoretically, a high intake of dietary sodium might reduce the effectiveness of antihypertensive drugs.
High intake of dietary sodium can increase systolic and diastolic blood pressure. Also, high intake of sodium may necessitate increased use of antihypertensive medications to achieve blood pressure control in some patients, such as those with chronic kidney disease.
Corticosteroids
Concomitant use of mineralocorticoids and some glucocorticoids with sodium supplements might increase the risk of hypernatremia.
Mineralocorticoids and some glucocorticoids (corticosteroids) cause sodium retention. This effect is dose-related and depends on mineralocorticoid potency. It is most common with hydrocortisone, cortisone, and fludrocortisone, followed by prednisone and prednisolone.
Didanosine (Videx)
Concomitant use of didanosine with additional sodium from dietary or supplemental sources may increase the risk of hypernatremia.
Didanosine formulations contain a significant amount of sodium.
Lithium
Altering dietary intake of sodium might alter the levels and clinical effects of lithium.
High sodium intake can reduce plasma concentrations of lithium by increasing lithium excretion. Reducing sodium intake can significantly increase plasma concentrations of lithium and cause lithium toxicity in patients being treated with lithium carbonate. Stabilizing sodium intake is shown to reduce the percentage of patients with lithium level fluctuations above 0.8 mEq/L. Patients taking lithium should avoid significant alterations in their dietary intake of sodium.
Sodium Phosphates
Theoretically, concomitant use of sodium phosphate with sodium supplements might increase the risk of hypernatremia.
Use of high doses (> 45 mL in 24 hours) of sodium phosphate, such as those used for bowel cleansing before surgery, can lead to serious electrolyte disturbances, including hypernatremia. The risk of hypernatremia is highest in the elderly and people with other risk factors for electrolyte disturbances.
Sodium-Containing Drugs
Concomitant use of sodium-containing drugs with additional sodium from dietary or supplemental sources may increase the risk of hypernatremia and long-term sodium-related complications.
The Chronic Disease Risk Reduction (CDRR) intake level of 2.3 grams of sodium daily indicates the intake at which it is believed that chronic disease risk increases for the apparently healthy population. Some medications contain high quantities of sodium. When used in conjunction with sodium supplements or high-sodium diets, the CDRR may be exceeded. Additionally, concomitant use may increase the risk for hypernatremia; this risk is highest in the elderly and people with other risk factors for electrolyte disturbances.
Tolvaptan (Samsca)
Theoretically, concomitant use of tolvaptan with sodium might increase the risk of hypernatremia.
Tolvaptan is a vasopressin receptor 2 antagonist that is used to increase sodium levels in patients with hyponatremia. Patients taking tolvaptan should use caution with the use of sodium salts such as sodium chloride.
Vitamin B12
Metformin (Glucophage)
Metformin, a common medication used to manage type 2 diabetes, has been associated with lower vitamin B12 levels in some individuals. Prolonged use of metformin can interfere with the absorption of B12 in the digestive system, potentially leading to a deficiency in this essential vitamin.
