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 3 of its 3 active ingredients.
  • No proprietary blends here — you can verify the dose of every single component.

GNC Mega Men Circulatory Health contains three active ingredients: L-Arginine, L-Citrulline, and Trans-Resveratrol. L-Arginine and L-Citrulline are amino acids that your body uses to boost nitric oxide, a compound that helps relax blood vessels and improve blood flow.

Trans-Resveratrol is a plant compound from grapes and berries. The capsule also contains inactive ingredients—microcrystalline cellulose, gelatin, stearic acid, hydroxypropylcellulose, magnesium stearate, titanium dioxide, and silica—which serve as binders and fillers.

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
Not established

The graded evidence we hold for these ingredients covers different conditions than the ones this product is marketed for, so there's no established rating for its stated use.

Why this rating?
  • The label markets this product for: Circulatory health and blood flow.
  • We looked for evidence on: Cardiovascular disease (CVD), Hypertension, Hypercholesterolemia, Heart failure, Erectile dysfunction (ED), Metabolic syndrome — and 4 related terms.
  • The closest evidence on file: Resveratrol is rated "Possibly Ineffective" for Cardiovascular disease (CVD) (Natural Medicines).
  • Also on file: Resveratrol is rated "Possibly Ineffective" for Hypercholesterolemia, Metabolic syndrome.
  • Also on file: Resveratrol is rated "Insufficient Reliable Evidence To Rate" for Hypertension.

The evidence for these ingredients is mixed. L-Citrulline is possibly effective for athletic performance, but possibly ineffective for sarcopenia (age-related muscle loss).

For cardiovascular disease, heart failure, Reye syndrome, and diabetes, the data is too sparse to rate its benefit. Trans-Resveratrol is possibly effective for obesity and hay fever (allergic rhinitis), but possibly ineffective for cardiovascular disease and high cholesterol.

L-Arginine has no effectiveness ratings in our data, so we can't speak to how well it works for circulatory health based on the evidence we hold.

The evidence, ingredient by ingredient L-arginine L-citrulline Resveratrol

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 3 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.

L-Arginine is generally well tolerated in the short term, but it can lower blood pressure and isn't safe for everyone—use only under medical supervision. Common side effects include abdominal pain, bloating, nausea, diarrhea, headache, insomnia, and flushing.

L-Citrulline is generally well tolerated in healthy adults, though long-term safety hasn't been fully studied; the most common side effects are gastrointestinal discomfort and heartburn. Trans-Resveratrol is generally well tolerated at typical doses, but high doses may cause digestive upset (diarrhea, loose stools, gastrointestinal discomfort).

There isn't enough safety data for L-Citrulline or Trans-Resveratrol in pregnancy or breastfeeding, so they should be avoided during those times. There is no pregnancy or breastfeeding data on file for L-Arginine.

Meds to double-check

Moderate interaction found
Known Interaction Concern · database check
Moderate identified

The most serious documented interaction for these ingredients is Moderate. Check your medications for a personalized result.

Why this rating?
  • 3 of the 3 matched ingredients can interact with medications — Resveratrol, L-arginine, L-citrulline.
  • The most serious interaction on file is rated Moderate.
  • Some involve high-stakes drug classes: anticoagulant / antiplatelet drugs; diabetes medications.
  • For scale: 1,051 individual medications appear in the full list. A big number alone doesn't make a product dangerous — what matters is whether YOUR medication is on it, so run yours through the interaction checker on this page.

Double-check the following medication types before taking this product: antihypertensive drugs (blood pressure medications), ACE inhibitors and ARBs, potassium-sparing diuretics, blood thinners and antiplatelet drugs, diabetes medications, heart medications like isoproterenol, and erectile dysfunction drugs including sildenafil and other phosphodiesterase-5 inhibitors. Additionally, if you take any drug metabolized by liver enzymes CYP2C19, CYP1A2, CYP3A4, or CYP2E1—a broad category that includes many common medications—resveratrol may raise its level in your blood.

The bottom line

Scorecard at a glanceFully disclosed formula with no established evidence rating for its marketed use. Moderate medication interactions have been identified, and safety information is well characterized.

This product is designed to support circulation, but it's not for everyone. If you take any blood pressure medication, blood thinner, diabetes drug, or heart medication, you need to talk with your pharmacist or doctor before starting it.

The ingredient L-Arginine especially requires supervision. Even if you're not on medications, the safety data advises caution and medical oversight rather than self-treatment.

Trans-Resveratrol5 drug types · 822 drugs

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.

Likelihood Possible Evidence D
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.

Likelihood Possible Evidence D
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.

Likelihood Possible Evidence D
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.

Likelihood Probable Evidence B
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.

Likelihood Possible Evidence D
Trans-Resveratrol full monograph & interactions

L-Arginine9 drug types · 403 drugs

Ace Inhibitors (Aceis)

Theoretically, concomitant use of L-arginine and ACE inhibitors may increase the risk for hypotension and hyperkalemia.
Combining L-arginine with some antihypertensive drugs, especially ACE inhibitors, seems to have additive vasodilating and blood pressure-lowering effects.

Theoretically, concomitant use of ACE inhibitors with L-arginine may increases the risk of hyperkalemia.

Likelihood Probable Evidence D
Angiotensin Receptor Blockers (Arbs)

Theoretically, concomitant use of L-arginine and ARBs may increase the risk of hypotension and hyperkalemia.
L-arginine increases nitric oxide, which causes vasodilation. Combining L-arginine with ARBs seems to increase L-arginine-induced vasodilation. Furthermore, ARBs can increase potassium levels. Use of L-arginine has been associated with hyperkalemia in some patients. Theoretically, concomitant use of ARBs with L-arginine may increases the risk of hyperkalemia.

Likelihood Probable Evidence D
Anticoagulant/Antiplatelet Drugs

Theoretically, concomitant use of L-arginine with anticoagulant and antiplatelet drugs might have additive effects and increase the risk of bleeding.
Preliminary research suggests that L-arginine infusions reduce platelet aggregation in humans. The clinical significance of this effect is unclear.

Likelihood Possible Evidence D
Antidiabetes Drugs

Theoretically, concomitant use of L-arginine might have additive effects with antidiabetes drugs.
Preliminary clinical research shows that L-arginine decreases blood glucose levels in patients with type 2 diabetes.

Likelihood Possible Evidence D
Antihypertensive Drugs

Theoretically, concomitant use of L-arginine and antihypertensive drugs may increase the risk of hypotension.
L-arginine increases nitric oxide, which causes vasodilation. Clinical evidence shows that L-arginine can reduce blood pressure in some individuals with hypertension. Furthermore, combining L-arginine with some antihypertensive drugs seems to have additive vasodilating and blood pressure-lowering effects.

Likelihood Probable Evidence D
Isoproterenol (Isuprel)

Theoretically, concurrent use of isoproterenol and L-arginine might result in additive effects and hypotension.
Preliminary clinical evidence suggests that L-arginine enhances isoproterenol-induced vasodilation in patients with essential hypertension or a family history of essential hypertension.

Likelihood Probable Evidence D
Potassium-Sparing Diuretics

Theoretically concomitant use of potassium-sparing diuretics with L-arginine may increases the risk of hyperkalemia.
Potassium-sparing diuretics can increase potassium levels. Use of L-arginine has been associated with hyperkalemia in some patients.

Likelihood Possible Evidence D
Sildenafil (Viagra)

Theoretically, concurrent use of sildenafil and L-arginine might increase the risk for hypotension.
In vivo, concurrent use of L-arginine and sildenafil has resulted in increased vasodilation. Theoretically, concurrent use might have additive vasodilatory and hypotensive effects. However, in studies evaluating the combined use of L-arginine and sildenafil for erectile dysfunction, hypotension was not reported.

Likelihood Possible Evidence D
Testosterone

Theoretically, concomitant use of L-arginine and testosterone might have additive effects.
In clinical research, L-arginine increases the level of testosterone in male patients with erectile dysfunction. The clinical significance of this finding is unclear.

Likelihood Possible Evidence D
L-Arginine full monograph & interactions

L-Citrulline2 drug types · 178 drugs

Antihypertensive Drugs

Theoretically, concomitant use of L-citrulline with antihypertensive drugs might have additive effects and increase the chance of hypotension.
L-citrulline is converted to L-arginine, which can increase nitric oxide and cause vasodilation. However, a meta-analysis of 5 small clinical studies suggests that taking L-citrulline 3-6 grams daily for 1-8 weeks does not lower blood pressure when compared with control.

Likelihood Possible Evidence B
Phosphodiesterase-5 Inhibitors

Theoretically, concurrent use of phosphodiesterase-5 (PDE-5) inhibitors and L-citrulline might result in additive vasodilation.
L-citrulline is converted to L-arginine, which can increase nitric oxide and cause vasodilation. Theoretically, taking L-arginine with PDE-5 inhibitors might have additive vasodilatory and hypotensive effects. However, in studies evaluating the combined use of L-arginine and sildenafil for erectile dysfunction, hypotension was not reported.

Circulatory Health by GNC Mega Men: Common Questions

Does Circulatory Health by GNC Mega Men interact with any medications?
Yes. Based on its ingredients, Circulatory Health has a known interaction with 1,050 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Circulatory Health contains 3 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 breastfeeding?
No. The safety data advises against L-Citrulline and Trans-Resveratrol in pregnancy and breastfeeding. There's no pregnancy or breastfeeding data on file for L-Arginine either. Talk with your doctor or pharmacist for guidance.
What are the most common side effects?
L-Arginine may cause abdominal pain, bloating, nausea, diarrhea, headache, insomnia, or flushing. L-Citrulline and Trans-Resveratrol most commonly cause gastrointestinal discomfort, heartburn, or diarrhea. These are generally mild, but if they're bothersome, stop and talk to us.
Does this product actually help circulation?
The evidence on L-Arginine for circulation isn't rated in our data. L-Citrulline has possibly effective evidence for athletic performance but insufficient evidence for cardiovascular disease. Trans-Resveratrol is possibly ineffective for cardiovascular disease. The evidence is limited.
What is L-Citrulline and why is it in this product?
L-Citrulline is an amino acid your body converts to L-Arginine to help increase nitric oxide, which relaxes blood vessels and may improve blood flow. It's included to support circulatory health, though the evidence for that benefit is sparse.
Why is there a warning about blood pressure medication?
L-Arginine and L-Citrulline can lower blood pressure by relaxing your blood vessels. If you're already taking a blood pressure medication, combining them could drop your pressure too low. That's why you need to check with your pharmacist or doctor first.
Can this increase my risk of bleeding?
Yes, theoretically. Both L-Arginine and Trans-Resveratrol may have effects that increase bleeding risk when combined with blood thinners or antiplatelet drugs like aspirin. If you take any of these, don't use this product without checking with your pharmacist.
