Every active ingredient lists its own amount on the label.

Why this rating?
  • The label discloses an exact amount for 5 of its 5 active ingredients.
  • No proprietary blends here — you can verify the dose of every single component.

MFX N.O. Tangerine Flavor contains 5 active ingredients.

Vitamin B3 (niacin) is included at a strength to support circulation and metabolic function. L-Alanine is an amino acid.

Arginine Alpha-Ketoglutarate and Betaine Nitrate are compounds meant to support muscle blood flow and performance. AgmaPure is a branded form of agmatine, an amino acid derivative.

The powder also contains inactive ingredients including citric acid, malic acid, cyclic dextrin, natural tangerine flavor, acesulfame potassium, sucralose, and beta carotene.

Does it work?

Insufficient 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
Insufficient

There isn't enough reliable clinical evidence to rate this product's ingredients for its stated purpose.

Why this rating?
  • The label markets this product for: increase nitric oxide for athletic performance.
  • We looked for evidence on: Athletic performance, Muscle strength, exercise endurance, blood flow, oxygen delivery.
  • The closest evidence on file: Niacin is rated "Insufficient Reliable Evidence To Rate" for Athletic performance (Natural Medicines).
  • Also on file: Agmatine is rated "Insufficient Reliable Evidence To Rate" for Athletic performance, Muscle strength.

In our data, Vitamin B3 is rated Likely Effective for pellagra (a niacin-deficiency disease) and Possibly Effective for HIV/AIDS-related cholesterol problems and metabolic syndrome. L-Alanine and AgmaPure both show Insufficient Reliable Evidence in the conditions we hold on file — meaning the science hasn't yet established whether they work for those purposes.

We don't have effectiveness ratings for Arginine Alpha-Ketoglutarate or Betaine Nitrate.

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 3 matched ingredients.
  • Pregnancy & breastfeeding safety ratings cover 3 of 3.
  • General safety write-ups exist for 3 of 3.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

Vitamin B3 is generally well tolerated in food amounts and prescription doses under medical supervision. Common side effects include flushing (up to 70% of patients at higher doses), gastrointestinal upset (nausea, heartburn, abdominal pain, diarrhea), and elevated liver enzymes.

Rare serious effects include liver damage, muscle damage, and blood clotting problems. High-dose niacin should be avoided in pregnancy unless prescribed by your doctor.

L-Alanine is rated Likely Safe in pregnancy and lactation, though supplement safety and benefits are not well studied. AgmaPure appears well tolerated short-term but has not been well studied long-term; it should be avoided during pregnancy and breastfeeding due to insufficient safety data.

AgmaPure's common side effects include diarrhea, indigestion, and nausea, which resolved when people stopped taking it in small studies.

Vitamin B315 drug types · 727 drugs

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.

Likelihood Probable Evidence D
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.

Likelihood Probable Evidence C
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.

Likelihood Possible Evidence D
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.

Likelihood Probable Evidence B
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.

Likelihood Possible Evidence B
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%.

Likelihood Possible Evidence D
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.

Likelihood Possible Evidence D
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.

Likelihood Possible Evidence D
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).

Likelihood Possible Evidence D
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.

Likelihood Probable Evidence C
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.

Likelihood Probable Evidence C
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.

Likelihood Probable Evidence D
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.

Likelihood Possible Evidence D
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.

Likelihood Possible Evidence D
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.

Likelihood Likely Evidence B
Vitamin B3 full monograph & interactions

AgmaPure2 drug types · 258 drugs

Antidiabetes Drugs

Theoretically, agmatine might increase the risk of hypoglycemia when taken with antidiabetes drugs.
Animal and in vitro research suggest that agmatine has mild hypoglycemic effects.

Likelihood Possible Evidence D
Antihypertensive Drugs

Theoretically, agmatine might increase the risk of hypotension when taken with antihypertensive drugs.
Animal research suggests that agmatine can modestly decrease heart rate and blood pressure.

MFX N.O. Tangerine Flavor by Muscle Feast: Common Questions

Does MFX N.O. Tangerine Flavor by Muscle Feast interact with any medications?
Yes. Based on its ingredients, MFX N.O. Tangerine Flavor has a known interaction with 727 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
MFX N.O. Tangerine Flavor contains 5 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.
Can I take this if I'm pregnant or nursing?
Vitamin B3 at normal doses is rated Likely Safe in pregnancy, but high-dose niacin should be avoided unless your doctor prescribes it. L-Alanine is Likely Safe. AgmaPure should be avoided during pregnancy and breastfeeding because there isn't enough safety data. Talk with your doctor or pharmacist about your personal situation before starting.
What does the niacin in this do?
Niacin (Vitamin B3) supports circulation and is rated Likely Effective for preventing pellagra, a niacin-deficiency disease, and Possibly Effective for cholesterol and metabolic issues in people with HIV/AIDS. In this workout product, it's included to help blood flow to muscles.
Why is there a warning about flushing?
Flushing — redness, warmth, and tingling of the face and upper body — is a very common side effect of niacin, especially at higher doses. Clinical studies show up to 70% of people taking niacin for health purposes experience it. It's usually harmless and goes away with time, though it can be uncomfortable.
What's AgmaPure and what's it supposed to do?
AgmaPure is agmatine, an amino acid compound meant to support muscle blood flow and athletic performance. However, we don't have reliable evidence yet that it works for those purposes. It appears well tolerated short-term but hasn't been studied long-term in humans.
Can I take this with my blood pressure medication?
Both niacin and agmatine in this product may increase the blood-pressure-lowering effects of your medication, potentially causing unsafe drops in blood pressure. Do not take this without checking with your doctor or pharmacist first — they can review your specific medication and advise you.
