What’s inside

Full disclosure
Ingredient Transparency · database check
Full

Every active ingredient lists its own amount on the label.

Why this rating?
  • The label discloses an exact amount for 7 of its 7 active ingredients.
  • “Cordyceps Mycelium Extract” is listed as a grouped ingredient — the label gives one combined amount (200 mg) without saying how much of each component you get.

Renagen DTX contains 7 active ingredients. Vitamin B6 supports nerve function and metabolism; vitamin B12 helps with energy and nervous system health; N-acetyl cysteine is an amino acid that aids detoxification; Chinese salvia is an herbal extract traditionally used in Chinese medicine; adenosine is a nucleoside involved in energy and cell signaling; plus two others—Cordyceps Mycelium Extract and Cordycepic Acid—for which we have limited data.

The product also contains inactive ingredients like the capsule material and microcrystalline cellulose.

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
Strong

Clinical evidence supports at least one of this product's ingredients for its stated purpose.

Why this rating?
  • The label markets this product for: support healthy kidney detoxification and protect against free radical damage.
  • We looked for evidence on: Chronic kidney disease (CKD), Acetaminophen poisoning, Cyanide poisoning, kidney function, renal support, antioxidant protection — and 1 related terms.
  • The strongest evidence on file: N-acetyl Cysteine (nac) is rated "Effective" for Acetaminophen poisoning (Natural Medicines).
  • Also on file: Vitamin B12 is rated "Likely Effective" for Cyanide poisoning.
  • Also on file: N-acetyl Cysteine (nac) is rated "Insufficient Reliable Evidence To Rate" for Chronic kidney disease (CKD).

The data we hold shows vitamin B6 is effective for sideroblastic anemia and B6 deficiency, likely effective for high homocysteine, and possibly effective for pregnancy-related nausea. Vitamin B12 is effective for B12 deficiency and certain rare conditions, and possibly effective for canker sores and nerve pain.

N-acetyl cysteine is effective for acetaminophen poisoning and certain lung conditions, and possibly effective for bronchitis. For the others—Chinese salvia, adenosine, Cordyceps Mycelium Extract, and cordycepic acid—either the evidence isn't established in our data or we hold insufficient reliable evidence to rate them for the conditions this product may be marketed toward.

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 5 of the 5 matched ingredients.
  • Pregnancy & breastfeeding safety ratings cover 5 of 5.
  • General safety write-ups exist for 5 of 5.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

Vitamin B6 is generally well tolerated at doses under 100 mg daily, but high doses over time can harm nerves (sensory neuropathy); common side effects at any dose include headache, nausea, and vomiting. Vitamin B12 is very safe with no established upper limit and is generally well tolerated; injection-site reactions may occur with injections.

N-acetyl cysteine is generally well tolerated at typical doses but can cause nausea, diarrhea, and dry mouth; joint pain has been reported in some users. Chinese salvia may affect blood clotting and is best avoided in pregnancy and while breastfeeding.

Adenosine safety data are limited for oral supplements; the prescription injectable form carries serious cardiovascular risks. For pregnancy and lactation: vitamin B6 is rated Likely Safe but also Possibly Unsafe (guidance varies), vitamin B12 is Likely Safe, N-acetyl cysteine is Possibly Safe, Chinese salvia should be avoided, and adenosine safety is not established—talk with your doctor or pharmacist before use in pregnancy or while breastfeeding.

Chinese Salvia16 drug types · 1,059 drugs

Anticoagulant/Antiplatelet Drugs

Theoretically, danshen may increase the risk of bleeding if used with anticoagulant or antiplatelet drugs.
Danshen has been reported to have antithrombotic effects. Animal research also suggests that taking a danshen combination formula with clopidogrel exhibits a synergistic increase in antiplatelet aggregation and prolongation of coagulation time when compared with either taken alone.

Likelihood Probable Evidence D
Digoxin (Lanoxin)

Theoretically, using danshen with digoxin might increase the risk of adverse effects.
Danshen has structural and pharmacological similarities to cardiac glycosides.

Likelihood Probable Evidence D
Amlodipine (Norvasc)

Theoretically, taking danshen in combination with amlodipine may decrease the clinical effects of amlodipine.
In animal research, taking danshen orally in combination with amlodipine reduced blood levels of amlodipine by about 52%. This may have been due to induction of cytochrome P450 3A4 (CYP3A4) by danshen, which has been demonstrated in vitro. So far, this interaction has not been reported in humans.

Likelihood Possible Evidence D
Antihypertensive Drugs

Theoretically, taking danshen with antihypertensive drugs might increase the risk of hypotension.
Animal research suggests that danshen can produce dose-dependent hypotensive effects. Furthermore, concomitant use with captopril appears to potentiate this effect.

Likelihood Possible Evidence D
Aspirin

Theoretically, danshen may increase the levels of aspirin and the risk of bleeding.
Research in healthy adult males shows that taking a combination of danshen and kudzu with aspirin increases plasma aspirin area under the curve by approximately 3.4-fold. Animal research also shows that taking a combination of danshen and kudzu (danshen-gegen formula) with aspirin increases maximal blood levels of aspirin and salicylic acid by approximately 4-fold and 3.7-fold, respectively, without impacting blood loss. Taking danshen increases the antiplatelet activity of aspirin and might increase the side effects of aspirin.

Likelihood Probable Evidence B
Clopidogrel (Plavix)

Theoretically, danshen may increase the risk of bleeding if taken with clopidogrel.
Clopidogrel is an antiplatelet prodrug that is metabolized by carboxyl esterase 1 (CES1) to an inactive metabolite. Animal research shows that a danshen combination formula decreases the activity of CES1, decreasing levels of the inactive metabolite in the blood and possibly increasing levels of the active metabolite. Animal research also suggests that taking a danshen combination formula with clopidogrel exhibits a synergistic increase in antiplatelet aggregation and prolongation of coagulation time when compared with either taken alone.

Likelihood Possible Evidence D
Cytochrome P450 1A2 (Cyp1A2) Substrates

Theoretically, danshen may increase the levels and clinical effects of drugs metabolized by CYP1A2.
In vitro research shows that danshen tincture and various constituents of danshen inhibit the activity of CYP1A2. However, this activity has not been shown in humans when theophylline, a CYP1A2 substrate, was used as a target drug.

Likelihood Possible Evidence D
Cytochrome P450 2C9 (Cyp2C9) Substrates

Theoretically, danshen may increase the levels and clinical effects of drugs metabolized by CYP2C9.
In vitro research shows that various constituents of danshen inhibit the activity of CYP2C9. So far, this interaction has not been reported in humans.

Likelihood Possible Evidence D
Cytochrome P450 2E1 (Cyp2E1) Substrates

Theoretically, danshen may increase the levels and clinical effects of drugs metabolized by CYP2E1.
In vitro research shows that various constituents of danshen inhibit the activity of CYP2E1. So far, this interaction has not been reported in humans.

Likelihood Possible Evidence D
Cytochrome P450 3A4 (Cyp3A4) Substrates

Danshen might alter the levels and clinical effects of drugs metabolized by CYP3A4.
Preliminary clinical research in healthy males shows that the administration of danshen for 10-14 days induces intestinal CYP3A4 and increases the clearance of midazolam, a CYP3A4 substrate. The maximum concentration of midazolam was decreased by 31% to 67%, and drug levels were decreased by 27% to 80%. However, a single dose of danshen has the opposite effect, increasing maximum concentrations of midazolam by 87%.

Likelihood Possible Evidence B
Fexofenadine (Allegra)

Danshen might increase the levels and clinical effects of fexofenadine.
Pharmacokinetic research in healthy volunteers shows that taking danshen extract 1 gram three times daily for 10 days prior to receiving fexofenadine 60 mg increases peak levels of fexofenadine, a p-glycoprotein substrate, by 27.4% and area under the curve (AUC) by 37.2%.

Likelihood Probable Evidence B
Glucuronidated Drugs

Theoretically, danshen might affect the levels and clinical effects of drugs requiring glucuronidation.
In vitro research shows that danshen induces the expression of glucuronosyltransferases. However, it also inhibits the activity of glucuronosyltransferases, including various members of the 1A and 2B families. The extent of inhibition of a specific glucuronosyltransferase seems to be dependent on whether or not the danshen is processed via 'sweating'. This type of processing may affect the levels of constituents in danshen that alter glucuronosyltransferase activity. So far, this interaction has not been reported in humans.

Likelihood Possible Evidence D
Midazolam (Versed)

Danshen might alter the levels and clinical effects of midazolam.
Preliminary clinical research in healthy males shows that the administration of danshen for 10-14 days induces intestinal CYP3A4 and increases midazolam clearance. The maximum concentration was decreased by 31% to 67%, and drug levels were decreased by 27% to 80%. However, a single dose of danshen has the opposite effect, increasing maximum concentrations of midazolam by 87%.

Likelihood Probable Evidence B
P-Glycoprotein Substrates

Danshen might alter the levels of drugs cleared by p-glycoprotein.
Pharmacokinetic research in healthy volunteers suggests that danshen might affect p-glycoprotein activity. Taking danshen extract 1 gram three times daily for 10 days prior to receiving fexofenadine 60 mg increases peak levels of fexofenadine, a p-glycoprotein substrate, by 27.4% and area under the curve (AUC) by 37.2%.

Likelihood Possible Evidence B
Rosuvastatin (Crestor)

Theoretically, danshen might increase the levels and clinical effects of rosuvastatin.
Animal research shows that a single dose of danshen increases levels of rosuvastatin at least 2-fold, possibly by increasing absorption and/or decreasing elimination. So far, this interaction has not been reported in humans.

Likelihood Possible Evidence D
Warfarin (Coumadin)

Theoretically, danshen may increase the risk of bleeding if used with warfarin.
There have been several case reports of increased international normalized ratio (INR) after concomitant use of danshen and warfarin. Elevations in INR have occurred as early as 3-5 days after start of danshen. However, a clinical trial in adults taking warfarin with stable INR found that the addition of compound danshen dripping pills, containing danshen extract, Panax notoginseng, and borneol, 270 mg three times daily for 4 weeks did not alter INR levels or the average required warfarin dose when compared to baseline. These findings are consistent with animal research, which found no change in warfarin pharmacokinetics with the use of danshen. Other research in healthy adult males also shows that taking a combination of danshen and kudzu with warfarin does not increases plasma warfarin area under the curve, but may reduce plasma soluble thrombomodulin levels. However, other research shows that danshen might increase the rate of absorption and decrease the elimination rate of warfarin. Also, research in healthy adult males shows that taking a combination of danshen and kudzu with warfarin increases plasma area under the curve of danshensu, a constituent of danshen, by approximately 29.5-fold. Danshen should be used cautiously in patients taking warfarin.

Likelihood Possible Evidence B
Chinese Salvia full monograph & interactions

N-Acetylcysteine5 drug types · 294 drugs

Nitroglycerin

N-acetyl cysteine can increase the risk for hypotension and headaches when taken with intravenous or transdermal nitroglycerin.
Clinical research shows that concomitant administration of N-acetyl cysteine and intravenous or transdermal nitroglycerin can cause severe hypotension and intolerable headaches. Furthermore, in vitro research suggests that N-acetyl cysteine increases the anticoagulant activity of nitroglycerin.

Likelihood Probable Evidence B
Activated Charcoal

N-acetyl cysteine might reduce the effects of activated charcoal, while activated charcoal might reduce the absorption of N-acetyl cysteine.
N-acetyl cysteine appears to reduce the capacity of activated charcoal to adsorb acetaminophen and salicylic acid. Conversely, although clinical research suggests that although activated charcoal can reduce the absorption of N-acetyl cysteine by up to 40%, it does not seem to reduce its clinical effects. Other clinical evidence suggests that activated charcoal does not affect the absorption of N-acetyl cysteine.

Likelihood Possible Evidence D
Anticoagulant/Antiplatelet Drugs

Theoretically, N-acetyl cysteine might increase the risk of bleeding when taken with anticoagulant or antiplatelet drugs.
Clinical research suggests that intravenous N-acetyl cysteine decreases prothrombin time, prolongs coagulation time, decreases platelet aggregation, and increases blood loss in surgical patients. Furthermore, in vitro research suggests that N-acetyl cysteine increases the anticoagulant activity of nitroglycerin.

Likelihood Possible Evidence D
Antihypertensive Drugs

Theoretically, N-acetyl cysteine might increase the risk of hypotension when taken with antihypertensive drugs.
Animal research suggests that N-acetyl cysteine potentiates the hypotensive effects of the angiotensin-converting enzyme inhibitors (ACEIs) captopril and enalaprilat. Theoretically, combining N-acetyl cysteine with other antihypertensive drugs might increase the risk of hypotension.

Likelihood Possible Evidence D
Chloroquine (Aralen)

Theoretically, N-acetyl cysteine might interfere with the antimalarial effects of chloroquine.
Animal research suggests that N-acetyl cysteine might reduce the antimalarial effects of chloroquine by increasing cellular levels of glutathione.

Likelihood Possible Evidence D
N-Acetylcysteine full monograph & interactions

Cordyceps Mycelium Extract3 drug types · 249 drugs

Anticoagulant/Antiplatelet Drugs

Theoretically, cordyceps may increase the risk of bleeding when used with antiplatelet or anticoagulant drugs.
In vitro and animal research suggests that cordyceps extract inhibits platelet aggregation and function. However, this interaction has not been reported in humans.

Likelihood Possible Evidence D
Immunosuppressants

Theoretically, concurrent use of cordyceps might interfere with immunosuppressive therapy.
Animal and in vitro research suggests that cordyceps stimulates the immune system. However, limited clinical research suggests that taking cordyceps may lower the necessary therapeutic dose of the immunosuppressant cyclosporine, which suggests that cordyceps may have an immunosuppressive effect.

Likelihood Possible Evidence B
Testosterone

Theoretically, concurrent use of cordyceps and testosterone might have additive effects.
Animal research suggests that cordyceps can increase testosterone levels. The clinical significance of this finding is unclear.

Likelihood Possible Evidence D
Cordyceps Mycelium Extract full monograph & interactions

Vitamin B65 drug types · 210 drugs

Amiodarone (Cordarone)

Theoretically, vitamin B6 might increase the photosensitivity caused by amiodarone.
Despite initial case reports suggesting that pyridoxine may have a protective effect against amiodarone-induced photosensitivity, preliminary clinical research suggests that pyridoxine may actually exacerbate this adverse effect.

Likelihood Possible Evidence B
Antihypertensive Drugs

Theoretically, vitamin B6 may have additive effects when used with antihypertensive drugs.
Research in hypertensive rats shows that vitamin B6 can decrease systolic blood pressure. Similarly, clinical research in patients with hypertension shows that taking high doses of vitamin B6 may reduce systolic and diastolic blood pressure, possibly by reducing plasma levels of epinephrine and norepinephrine.

Likelihood Possible Evidence B
Phenobarbital (Luminal)

High doses of vitamin B6 may reduce the levels and clinical effects of phenobarbital.
Preliminary clinical evidence suggests that vitamin B6 200 mg daily can reduce plasma levels of phenobarbital, possibly by increasing metabolism. It is not known whether lower doses have any effect. Advise people taking phenobarbital to avoid high doses of vitamin B6.

Likelihood Possible Evidence D
Phenytoin (Dilantin)

High doses of vitamin B6 may reduce the levels and clinical effects of phenytoin.
Preliminary clinical evidence suggests that vitamin B6 200 mg daily can reduce plasma levels of phenytoin, possibly by increasing metabolism. It is not known whether lower doses have any effect. Advise people taking phenytoin to avoid high doses of vitamin B6.

Likelihood Possible Evidence D
Levodopa

Vitamin B6 may increase the metabolism of levodopa when taken alone, but not when taken in conjunction with carbidopa.
Vitamin B6 (pyridoxine) enhances the metabolism of levodopa, reducing its clinical effects. However, this interaction does not occur when carbidopa is used concurrently with levodopa (Sinemet). Therefore, it is not likely to be a problem in most people.

Likelihood Unlikely Evidence D

Vitamin B121 drug type · 20 drugs

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.

Renagen DTX by Metagenics: Common Questions

Does Renagen DTX by Metagenics interact with any medications?
Yes. Based on its ingredients, Renagen DTX has a known interaction with 1,195 medications, including 124 rated major. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Renagen DTX contains 6 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 this safe to take if I'm pregnant?
The data is mixed and incomplete. Vitamin B6 is rated both Likely Safe and Possibly Unsafe—the discrepancy reflects genuine uncertainty. Vitamin B12 is Likely Safe. N-acetyl cysteine is Possibly Safe but hasn't been well studied. Chinese salvia and adenosine should be avoided. Don't take this without talking to your doctor or pharmacist first, since they know your full history.
What is N-acetyl cysteine for?
N-acetyl cysteine (NAC) is an amino acid that helps your body with detoxification and antioxidant defenses. It's proven effective for acetaminophen poisoning and certain lung conditions, and possibly helpful for bronchitis.
Can this product interact with blood thinners?
Yes. Both N-acetyl cysteine and Chinese salvia in this product can increase bleeding risk with blood thinners and antiplatelet drugs—that's a Major interaction. If you take any blood thinner or antiplatelet medication, check with your doctor or pharmacist before starting this product.
What does Chinese salvia do?
Chinese salvia (danshen) is an herbal extract used in traditional Chinese medicine. The evidence we hold isn't strong enough to rate it for the conditions it's commonly marketed for, so we can't say what it's proven to do. It does interact significantly with several medications.
Is vitamin B6 safe at high doses?
No. High doses over time can damage nerves (sensory neuropathy). The safety data advises against high doses unless a clinician advises it. At normal dietary amounts and standard supplement doses under 100 mg daily, it's well tolerated.
What is adenosine in this product for?
Adenosine is a nucleoside involved in energy production and cell signaling. It's proven effective as a prescription injectable for certain heart rhythm problems and heart imaging tests, but the evidence for oral supplement use is limited.
