HelloPharmacist Scorecard of NR6 by Xtendlife
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
NR6 contains 6 active ingredients. Trans-resveratrol is a polyphenol antioxidant derived from grapes and other plants; vitamin B12 is an essential nutrient that supports nerve function and red blood cell formation; nicotinamide riboside chloride is a form of B vitamin that plays a role in cellular energy.
The product also includes folate, dimethylglycine HCl, and piperine. Inactive ingredients (hydroxypropylmethyl cellulose and water) are there to form and fill the capsule.
Does it work?
Moderate evidence
Resveratrol shows possibly effective evidence for obesity and allergic rhinitis (hay fever), but it appears possibly ineffective for cardiovascular disease and high cholesterol. Vitamin B12 is effective for B12 deficiency and Imerslund-Grasbeck disease (a rare absorption disorder), and likely effective for cyanide poisoning; it's possibly effective for canker sores and postherpetic neuralgia (nerve pain after shingles).
For nicotinamide riboside, the evidence we hold does not establish effectiveness for the conditions listed — the data shows insufficient reliable evidence to rate it for age-related macular degeneration, Alzheimer's disease, athletic performance, liver disease, and heart failure.
How safe is it?
Well-documented data
Resveratrol is generally well tolerated at typical supplement doses; higher doses may cause diarrhea, loose stools, or gastrointestinal discomfort. Vitamin B12 is very safe — your body excretes excess B12 in urine, so there's no established upper limit.
Nicotinamide riboside appears well tolerated short-term, though long-term safety data are limited; reported side effects include bloating, nausea, muscle pain, and temporary changes in bowel habits. Regarding pregnancy: resveratrol concentrated supplements should be avoided (not enough safety data); vitamin B12 is needed and considered safe at normal recommended amounts, so follow your provider's guidance; nicotinamide riboside should be avoided in pregnancy and breastfeeding because we don't have adequate safety data.
Meds to double-check
Moderate interaction found
Before taking Xtendlife NR6, double-check the following with your pharmacist: blood thinners and antiplatelet drugs (resveratrol increases bleeding risk); drugs metabolized by liver enzyme CYP2C19, CYP1A2, CYP3A4, or CYP2E1 (resveratrol may increase their levels); metformin for diabetes (vitamin B12 may counter metformin's effect on B12 levels); and blood pressure medications (nicotinamide riboside may lower blood pressure further).
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.
NR6 may be right for you if you're interested in antioxidant and nutritional support, but it's not for everyone. If you take blood thinners, diabetes medication, or blood pressure medication, check with your pharmacist first.
The same goes for pregnancy and breastfeeding — talk to your doctor or pharmacist before starting.

NR6 by Xtendlife Drug Interactions
HelloPharmacist Interaction Report
Xtendlife NR6 contains ingredients with documented interactions affecting a substantial number of medications.
The most serious concern is resveratrol, which may increase bleeding risk if you take blood thinners or antiplatelet drugs (aspirin, clopidogrel, warfarin, dabigatran, and others) — a Moderate severity effect. Resveratrol can also theoretically increase blood levels of drugs metabolized by several liver enzymes (CYP2C19, CYP1A2, CYP3A4, and CYP2E1), though human evidence is limited; the CYP3A4 effect did not cause problems at high doses in one study, but theoretically higher concentrations could affect medications in this category.
Read the full breakdown — every affected drug type, severity by severity
Vitamin B12 carries a Minor interaction with metformin, a common diabetes medication — metformin can lower your B12 levels over time. Nicotinamide riboside may have additive blood-pressure-lowering effects if you're already on antihypertensive drugs (Minor severity).
We were not able to check folate, dimethylglycine HCl, or piperine — we hold no interaction data for them. Altogether, these interactions span 963 individual medications.
Before you start NR6, run your current medications through the interaction checker below, especially if you take blood thinners, diabetes medications, or blood pressure drugs.

Piperine
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.
Trans-Resveratrol
Anticoagulant/Antiplatelet Drugs
Resveratrol may have antiplatelet effects and may increase the risk of bleeding if used with anticoagulant or antiplatelet drugs.
Resveratrol seems to have antiplatelet effects.
Cytochrome P450 1A2 (Cyp1A2) Substrates
Theoretically, resveratrol might increase levels of drugs metabolized by CYP1A2.
In vitro research shows that resveratrol can inhibit CYP1A2 enzymes. However, this interaction has not been reported in humans.
Cytochrome P450 2C19 (Cyp2C19) Substrates
Theoretically, resveratrol might increase levels of drugs metabolized by CYP2C19.
In vitro research shows that resveratrol can inhibit CYP2C19 enzymes. However, this interaction has not been reported in humans.
Cytochrome P450 2E1 (Cyp2E1) Substrates
Resveratrol might increase levels of drugs metabolized by CYP2E1.
In vitro research suggests that resveratrol inhibits CYP2E1 isoenzyme. Also, a pharmacokinetic study shows that taking resveratrol 500 mg daily for 10 days prior to taking a single dose of chlorzoxazone 250 mg increases the maximum concentration of chlorzoxazone by about 54%, the area under the curve of chlorzoxazone by about 72%, and the half-life of chlorzoxazone by about 35%. Chlorzoxazone is used as a probe drug for CYP2E1.
Cytochrome P450 3A4 (Cyp3A4) Substrates
Theoretically, resveratrol might increase levels of drugs metabolized by CYP3A4.
In vitro research shows that resveratrol can inhibit the CYP3A4 enzyme. However, clinical research shows that taking resveratrol 3000 mg daily for 8 weeks does not necessitate dose adjustments to medications metabolized by CYP3A4.
Nicotinamide Riboside Chloride
Antihypertensive Drugs
Theoretically, nicotinamide riboside may have additive effects with antihypertensive drugs, potentially increasing the risk for hypotension.
One small clinical study suggests that nicotinamide riboside can modestly reduce blood pressure in hypertensive patients. However, other clinical research did not find a reduction in blood pressure when compared with control.
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.
