HelloPharmacist Scorecard of RNA-DNA Plus by Nutri-West
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
Partial disclosure
RNA-DNA Plus contains 13 ingredients, including the amino acid L-glutamine, the B vitamins niacin and vitamin B6, choline (a nutrient related to B vitamins), manganese (a trace mineral), and DL-methionine (another amino acid). It also includes tissue concentrates derived from parotid gland, adrenal, and trachea, plus RNA and DNA as actives.
The product contains no inactive fillers or binders listed.
Does it work?
Strong evidence
The evidence for this product's ingredients is mixed. L-glutamine is effective for sickle cell disease and possibly effective for recovery after surgery and for wasting related to HIV/AIDS.
Niacin is effective for pellagra (a deficiency disease) and possibly effective for dyslipidemia in HIV/AIDS and metabolic syndrome. Vitamin B6 is effective for certain anemias and B6 deficiency itself, and possibly effective for pregnancy-related nausea.
Choline, manganese, and the tissue concentrates have insufficient evidence or have not been established for most claimed uses in the data we hold. The RNA and DNA components have no effectiveness ratings on file.
How safe is it?
Well-documented data
L-glutamine is likely safe during pregnancy and lactation, though high supplement doses should be taken only under doctor supervision, and people with kidney or liver disease should use it only with medical oversight. It commonly causes belching, bloating, constipation, nausea, and diarrhea; at very high doses (10–30 grams daily), gastrointestinal effects are more frequent.
Niacin in normal dietary amounts is well tolerated, but high-dose supplements cause flushing in up to 70% of users and can harm the liver—especially sustained-release forms. Niacin is likely safe in pregnancy when used as prescribed, but high-dose supplements should be avoided.
Vitamin B6 is safe at normal levels but can cause nerve damage (sensory neuropathy) at very high daily doses or over long periods; it is likely safe in pregnancy at recommended doses but possibly unsafe at high levels. Choline is likely safe during pregnancy and lactation but can cause fishy body odor, nausea, vomiting, diarrhea, and other GI effects at doses above 3.5 grams daily.
Manganese is safe in food amounts but poses a rare risk of Parkinson-like symptoms and liver damage at high doses; the lactation data shows mixed ratings. We have no safety information on file for DL-methionine, vitamin B1, parotid, adrenal concentrate, RNA, DNA, or trachea concentrate.
Meds to double-check
Moderate interaction found
Before taking RNA-DNA Plus, double-check these medication types with your pharmacist or doctor: diabetes drugs (niacin raises blood sugar), antihypertensive medications (niacin and vitamin B6 may lower blood pressure further), seizure medications like phenobarbital and phenytoin (vitamin B6 at high doses may reduce their effect), blood thinners and antiplatelet drugs (niacin may increase bleeding risk), cholesterol-lowering statins (rare risk of muscle breakdown with niacin), antipsychotic drugs (manganese and vitamin B6 may interact), quinolone and tetracycline antibiotics (manganese may reduce their absorption), gout drugs like allopurinol and probenecid (niacin may interfere), bile acid sequestrants (space doses 4–6 hours apart from niacin), liver-toxic drugs (niacin adds risk), amiodarone (vitamin B6 may worsen photosensitivity), and levodopa (unless you also take carbidopa). No interactions are documented for the ingredients we could not check.
The bottom line
Scorecard at a glancePartially disclosed formula with strong clinical evidence behind its ingredients' uses. Moderate medication interactions have been identified, and safety information is well characterized.
RNA-DNA Plus is a multi-ingredient supplement with some ingredients backed by evidence (L-glutamine for sickle cell, niacin for deficiency) and others with unclear efficacy. If you take diabetes medications, blood pressure drugs, seizure medications, antipsychotics, statins, blood thinners, gout treatments, or antibiotics, you'll want to check your specific medications before starting this.

RNA-DNA Plus by Nutri-West Drug Interactions
HelloPharmacist Interaction Report
RNA-DNA Plus by Nutri-West contains several ingredients with documented interactions: L-glutamine, niacin, vitamin B6, choline, and manganese.
The most serious interaction is niacin's Moderate-severity effect on blood sugar control—niacin can raise blood glucose levels and may reduce how well diabetes medications work, a concern for anyone managing blood sugar.
Read the full breakdown — every affected drug type, severity by severity
Niacin also carries Moderate interactions with blood pressure medications (it can lower blood pressure further), liver-toxic drugs (niacin itself can harm the liver at high doses), blood thinners (some cases of clotting problems have been reported), cholesterol-lowering statins (rare risk of muscle breakdown), gout medications like allopurinol and probenecid (niacin may interfere with their ability to lower uric acid), and bile acid sequestrants (these binders can trap niacin and reduce how much your body absorbs—space doses 4–6 hours apart if you take both).
Vitamin B6 at high doses may interact with seizure medications like phenobarbital and phenytoin (possibly reducing their levels), antipsychotic drugs, blood pressure medications, amiodarone (a heart rhythm drug—vitamin B6 may worsen photosensitivity), and levodopa for Parkinson's disease (though this doesn't happen if you also take carbidopa). Manganese may reduce absorption of quinolone and tetracycline antibiotics and interact with antipsychotic drugs.
L-glutamine theoretically may antagonize seizure medications, and choline may decrease atropine's effects—both are Minor to Moderate concerns.
We could not check DL-methionine, vitamin B1, parotid, adrenal concentrate, RNA, DNA, or trachea concentrate for interactions. Altogether, these interactions span 863 individual medications.

For each ingredient in RNA-DNA Plus 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.
Niacin
Alcohol (Ethanol)
Concomitant use of alcohol and niacin might increase the risk of flushing and hepatotoxicity.
Alcohol can exacerbate the flushing and pruritus associated with niacin. Large doses of niacin might also exacerbate liver dysfunction associated with chronic alcohol use. A case report describes delirium and lactic acidosis in a patient taking niacin 3 grams daily who ingested 1 liter of wine. Advise patients to avoid large amounts of alcohol while taking niacin.
Allopurinol (Zyloprim)
Theoretically, niacin might antagonize the therapeutic effects of uricosurics such as allopurinol.
Large doses of niacin can reduce urinary excretion of uric acid, potentially resulting in hyperuricemia. Doses of uricosurics such as allopurinol might need to be increased to maintain control of gout in patients who start taking niacin. People who have frequent attacks of gout despite uricosuric therapy should avoid niacin.
Anticoagulant/Antiplatelet Drugs
Theoretically, niacin may have additive effects when used with anticoagulant or antiplatelet drugs.
Several cases of clotting factor synthesis deficiency and coagulopathy have been reported in patients taking sustained-release niacin. Also, thrombocytopenia has been reported in patients treated with niacin or niacin plus lovastatin.
Antidiabetes Drugs
Niacin can increase blood glucose levels and may diminish the effects of antidiabetes drugs.
Niacin impairs glucose tolerance in a dose-dependent manner, probably by causing or aggravating insulin resistance and increasing hepatic production of glucose. In diabetes patients, niacin 4.5 grams daily for 5 weeks can increase plasma glucose by an average of 16% and glycated hemoglobin (HbA1c) by 21%. However, lower doses of 1.5 grams daily or less appear to have minimal effects on blood glucose. In some patients, glucose levels increase when niacin is started, but then return to baseline when a stable dose is reached. Up to 35% of patients with diabetes may need adjustments in hypoglycemic therapy when niacin is added.
Antihypertensive Drugs
Theoretically, niacin may increase the risk of hypotension when used with antihypertensive drugs.
The vasodilating effects of niacin can cause hypotension. Furthermore, some clinical evidence suggests that a one-hour infusion of niacin can reduce systolic, diastolic, and mean blood pressure in hypertensive patients. This effect is not observed in normotensive patients.
Bile Acid Sequestrants
Bile acid sequestrants can bind niacin and decrease absorption. Separate administration by 4-6 hours to avoid an interaction.
In vitro studies show that colestipol (Colestid) binds about 98% of available niacin and cholestyramine (Questran) binds 10% to 30%.
Gemfibrozil (Lopid)
Theoretically, concomitant use of niacin and gemfibrozil might increase the risk of myopathy in some patients.
A case of myopathy from concomitant use of niacin and gemfibrozil has been reported. Niacin alone has also been associated with cases of myopathy. Using gemfibrozil with niacin might further increase the risk of developing myopathy.
Hepatotoxic Drugs
Theoretically, concomitant use of niacin and hepatotoxic drugs might increase the risk of hepatotoxicity.
Niacin has been associated with cases of liver toxicity, especially when used in pharmacologic doses. Sustained-release niacin preparations appear to be associated with a higher risk of hepatotoxicity than immediate-release niacin.
Hmg-Coa Reductase Inhibitors ("Statins")
Theoretically, concomitant use of niacin and statins might increase the risk of myopathy and rhabdomyolysis in some patients.
Some case reports have raised concerns that niacin might increase the risk of myopathy and rhabdomyolysis when combined with statins. However, a significantly increased risk of myopathy has not been demonstrated in clinical trials, including those using an FDA-approved combination of lovastatin and niacin (Advicor).
Probenecid (Benemid)
Theoretically, niacin might antagonize the therapeutic effects of uricosurics such as probenecid.
Large doses of niacin reduce urinary excretion of uric acid, potentially causing hyperuricemia. Doses of uricosurics such as probenecid might need to be increased to maintain control of gout in patients who start taking niacin. People who have frequent attacks of gout despite uricosuric therapy should avoid niacin.
Sulfinpyrazone (Anturane)
Theoretically, niacin might antagonize the therapeutic effects of uricosurics such as sulfinpyrazone.
Large doses of niacin reduce urinary excretion of uric acid, potentially causing hyperuricemia. Doses of uricosurics such as sulfinpyrazone might need to be increased to maintain control of gout in patients who start taking niacin. People who have frequent attacks of gout despite uricosuric therapy should avoid niacin.
Thyroid Hormone
Theoretically, niacin might antagonize the therapeutic effects of thyroid hormones.
Clinical research and case reports suggests that taking niacin can reduce serum levels of thyroxine-binding globulin by up to 25% and moderately reduce levels of thyroxine (T4). Patients taking thyroid hormone for hypothyroidism might need dose adjustments when using niacin.
Transdermal Nicotine (Nicoderm)
Theoretically, concomitant use of niacin and transdermal nicotine might increase the risk of flushing and dizziness.
Niacin and nicotine can both cause flushing and dizziness.
Warfarin (Coumadin)
There is limited evidence that niacin may increase the anticoagulant effects of warfarin.
In a case report, a patient on warfarin developed an elevated international normalized ratio (INR) of 3.9 after taking niacin for two weeks. The patient's INR was previously stable, ranging between 2 and 3 in recent months, and no other medication changes were identified. The elevated INR returned to therapeutic range within 4 days following the discontinuation of niacin.
Aspirin
Large doses of aspirin might alter the clearance of niacin.
Aspirin is often used with niacin to reduce niacin-induced flushing. Doses of 80-975 mg aspirin have been used, but 325 mg appears to be optimal. Aspirin also seems to reduce the clearance of niacin by competing for glycine conjugation. Taking aspirin 1 gram seems to reduce niacin clearance by 45%. This is probably a dose-related effect and not clinically significant with the more common aspirin dose of 325 mg.
Vitamin B6
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.
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.
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.
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.
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.
Manganese
Antipsychotic Drugs
Theoretically, the risk for manganese toxicity might increase when taken with antipsychotic drugs.
Hallucinations and behavioral changes have been reported in a patient with liver disease who was taking haloperidol and manganese. Researchers speculate that taking manganese along with haloperidol, phenothiazine-derivatives, or other antipsychotic medications might increase the risk of manganese toxicity in some patients.
Quinolone Antibiotics
Theoretically, manganese might reduce the absorption of quinolone antibiotics.
Manganese is a multivalent cation. Interactions resulting in reduced quinolone absorption have been reported between quinolones and other multivalent cations, such as calcium and iron.
Tetracycline Antibiotics
Theoretically, manganese might reduce the absorption of tetracycline antibiotics.
Manganese is a multivalent cation. Interactions resulting in reduced tetracycline absorption have been reported between tetracyclines and other multivalent cations, such as calcium and iron.
L-Glutamine
Anticonvulsants
Theoretically, glutamine might antagonize the effects of anticonvulsant medications.
Glutamine is metabolized to the excitatory neurotransmitter glutamate. Glutamate might have antagonistic effects with anticonvulsant drugs. However, this interaction has not yet been reported in humans.
Choline
Atropine
Theoretically, choline might decrease the effects of atropine in the brain.
Animal research shows that administering choline one hour before administering atropine can attenuate atropine-induced decreases in brain levels of acetylcholine. Theoretically, concomitant use of choline and atropine may decrease the effects of atropine.
