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 4 of its 4 active ingredients.
  • No proprietary blends here — you can verify the dose of every single component.

Ibuta Lean contains four active ingredients. L-Arginine is an amino acid that increases nitric oxide in the body, which affects blood vessel dilation and blood pressure.

Maca Powder is a root extract traditionally used in supplements, though evidence for specific effects is limited. Mucuna pruriens seed extract is a legume seed that naturally contains levodopa, an active compound similar to medication used in Parkinson's disease treatment.

Hawthorn Extract comes from the hawthorn plant and is used in supplements for heart-related purposes. The capsules also contain inactive ingredients: hypromellose, cellulose, silica, and magnesium stearate (common fillers and binders).

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 assessable

The label doesn't state a purpose we can grade — see each ingredient's own graded uses on its monograph instead.

Why this rating?
  • We looked at the product name, claims, and label statements and couldn't find a stated purpose to grade.

The evidence base for these ingredients is limited. L-Arginine, Maca Powder, Mucuna pruriens seed extract, and Hawthorn Extract all have insufficient reliable evidence in our data to establish effectiveness for any specific condition.

Because the product claims relate to athletic performance and body composition, and we hold no effectiveness ratings supporting those uses, the scientific foundation for this product's intended purpose isn't established in the data we maintain.

The evidence, ingredient by ingredient L-arginine Maca Cowhage Hawthorn

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 4 of the 4 matched ingredients.
  • Pregnancy & breastfeeding safety ratings cover 4 of 4.
  • General safety write-ups exist for 4 of 4.
  • 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, though it can lower blood pressure and isn't safe for everyone — use only under medical supervision, as safety for self-treatment isn't well established. Common side effects include abdominal pain, bloating, nausea, diarrhea, headache, insomnia, and flushing.

When inhaled, it can inflame airways, but oral use in asthma studies has not shown airway problems. Mucuna pruriens contains levodopa and should be used carefully with professional guidance; a thorough safety evaluation hasn't been done, but reported oral effects are rare and include diarrhea, flatulence, mucosal irritation, nausea, abdominal distention, vomiting, headaches, and insomnia (about 3% in one trial).

Maca is generally well tolerated as a food but lacks long-term supplement safety data; fresh uncooked maca may cause stomach pain. Hawthorn is generally well tolerated in studies, though rare serious effects like multiorgan hypersensitivity reactions and renal failure have been reported; palpitations and tachycardia have occurred in cardiac patients.

Pregnancy and lactation data are not on file for L-Arginine, Maca safety data advises against use in pregnancy and breastfeeding, Mucuna pruriens should be avoided in pregnancy due to levodopa's dopamine effects and should be avoided while breastfeeding because levodopa can lower milk supply, and Hawthorn data advises against use in pregnancy and breastfeeding.

Major interaction found
Known Interaction Concern · database check
Major identified

At least one ingredient has a documented Major-severity interaction. Check your medications for a personalized result.

Why this rating?
  • 3 of the 4 matched ingredients can interact with medications — Hawthorn, L-arginine, Cowhage.
  • The most serious interaction on file is rated Major.
  • Some involve high-stakes drug classes: anticoagulant / antiplatelet drugs; diabetes medications; heart-rhythm medications; Parkinson's medications.
  • For scale: 522 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.

Before you take this product, double-check any blood pressure medicines you're on — especially methyldopa, ACE inhibitors, ARBs, beta-blockers, calcium channel blockers, nitrates, or other antihypertensives — because Ibuta Lean may lower blood pressure further. If you take any antidepressant, check it first: MAOIs (a serious concern with this product's levodopa content), tricyclic antidepressants, and other types all interact.

Also check blood thinners or antiplatelet drugs, diabetes medications, digoxin or other heart medicines, phosphodiesterase-5 inhibitors like sildenafil, antipsychotic drugs, and potassium-sparing diuretics. Use the medication checker on this page to confirm your exact medications.

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. Furthermore, ACE inhibitors can increase potassium levels. Use of L-arginine has been associated with hyperkalemia in some patients. 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

Mucuna pruriens seed extract8 drug types · 193 drugs

Levodopa

Concomitant use can increase the risk of levodopa-related adverse effects.
Cowhage contains levodopa. Some cowhage products have been standardized to contain 75-400 mg of levodopa per dose.

Likelihood Likely Evidence D
Methyldopa (Aldomet)

Theoretically, concomitant use of cowhage and methyldopa might increase the risk of hypotension.
Cowhage contains levodopa. Use of levodopa with methyldopa might cause additive hypotension. In addition, methyldopa may inhibit peripheral decarboxylation of levodopa and increase levodopa levels in the central nervous system; avoid using.

Likelihood Probable Evidence D
Monoamine Oxidase Inhibitors (Maois)

Theoretically, concomitant use of cowhage and non-selective MAOIs might increase the risk of hypertensive crisis.
Cowhage contains levodopa. Use of levodopa with non-selective MAOIs might cause hypertensive crisis. However, this interaction has not been reported with MAO-B selective inhibitors such as selegiline.

Likelihood Probable Evidence D
Anesthesia

Theoretically, concomitant use of cowhage and anesthesia might increase the risk of arrhythmias.
Cowhage contains levodopa. Use of levodopa with cyclopropane or halogenated hydrocarbon anesthesia has led to arrhythmias. Other anesthetics have not been implicated. Use other anesthetics in patients taking cowhage or tell patients to stop taking cowhage at least 2 weeks before surgery.

Likelihood Possible Evidence D
Antidiabetes Drugs

Theoretically, concomitant use of cowhage and antidiabetes drugs might increase the risk of hypoglycemia.
Animal research shows that cowhage might have hypoglycemic effects.

Likelihood Possible Evidence D
Antipsychotic Drugs

Theoretically, use of cowhage might decrease the clinical effects of antipsychotic drugs.
Cowhage contains levodopa. Use of levodopa might counteract the antidopaminergic effects of antipsychotic medications.

Likelihood Possible Evidence D
Guanethidine (Ismelin)

Theoretically, concomitant use of cowhage and guanethidine might increase the risk of hypotension.
Cowhage contains levodopa. Use of levodopa with guanethidine might cause additive hypotension; avoid using.

Likelihood Probable Evidence D
Tricyclic Antidepressants (Tcas)

Theoretically, use of TCAs might reduce the levels and clinical effects of cowhage.
Cowhage contains levodopa. Use of TCAs might reduce the absorption of levodopa. Some case reports describe patients that developed hypertension and dyskinesia when taking both levodopa and TCAs.

Likelihood Possible Evidence D
Mucuna pruriens seed extract full monograph & interactions

Hawthorn Extract6 drug types · 191 drugs

Nitrates

Theoretically, concomitant use might cause additive coronary vasodilatory effects.
Some evidence shows that hawthorn might lower blood pressure due to vasodilatory effects.

Likelihood Probable Evidence D
Phosphodiesterase-5 Inhibitors

Theoretically, concomitant use might result in additive vasodilation and hypotension.
Hawthorn might inhibit PDE-5 and cause vasodilation.

Likelihood Probable Evidence D
Anticoagulant/Antiplatelet Drugs

Theoretically, hawthorn may increase the risk of bleeding if used with anticoagulant or antiplatelet drugs.
In vitro and animal research shows that hawthorn can inhibit platelet aggregation. However, its effect in humans is unclear. One observational study shows that patients taking hawthorn shortly before undergoing coronary artery bypass graft (CABG) surgery or valve replacement surgery have a 10% incidence of postoperative bleeding, compared with 1% in those who never consumed hawthorn extract. However, clinical research shows that taking a specific preparation of dried hawthorn leaves and flowers (Crataesor, Soria Natural Lab) 800 mg three times daily for 15 days does not affect platelet aggregation or levels of thromboxane B2, the metabolite of thromboxane A2, in healthy humans.

Likelihood Possible Evidence D
Beta-Blockers

Theoretically, concomitant use might cause additive effects on blood pressure and heart rate.
Some evidence shows that hawthorn might lower blood pressure and heart rate.

Likelihood Possible Evidence D
Calcium Channel Blockers

Theoretically, concomitant use might cause additive coronary vasodilation and hypotensive effects.
Some evidence shows that hawthorn might lower blood pressure due to vasodilatory effects.

Likelihood Possible Evidence D
Digoxin (Lanoxin)

Theoretically, hawthorn might potentiate the effects and adverse effects of digoxin.
Hawthorn appears to improve cardiac output; however, hawthorn does not appear to affect digoxin pharmacokinetics. Case reports suggest that at least one species of hawthorn root extract (Crataegus mexicana) may produce adverse effects similar to digoxin and can cross-react with digoxin assays, leading to falsely elevated plasma digoxin levels.

Ibuta Lean by Brutal Force: Common Questions

Does Ibuta Lean by Brutal Force interact with any medications?
Yes. Based on its ingredients, Ibuta Lean has a known interaction with 522 medications, including 31 rated major. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Ibuta Lean contains 4 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.
What is Mucuna pruriens and why should I be careful with it?
Mucuna pruriens is a seed extract that naturally contains levodopa, an active compound similar to medication used for Parkinson's disease. Because levodopa is a drug-like substance, it interacts with several medications — especially antidepressants, blood pressure drugs, and anesthetics. This is why the product advises careful use under professional guidance.
Can I take Ibuta Lean if I'm on blood pressure medicine?
L-Arginine and Hawthorn in this product may lower blood pressure, so combining them with blood pressure drugs could cause your pressure to drop too far. Don't start this product without checking your specific medication against the tool on this page and talking to your pharmacist or doctor first.
Is it safe to take during pregnancy or while breastfeeding?
No. Maca should be avoided in pregnancy and while breastfeeding due to insufficient safety data. Mucuna pruriens should also be avoided in pregnancy; while breastfeeding, its levodopa content can lower milk supply. L-Arginine and Hawthorn safety data for pregnancy and lactation are not on file — talk to your doctor or pharmacist for personalized advice.
What does this product actually do?
The scientific evidence for these ingredients is insufficient to establish what Ibuta Lean actually does. Our data shows no proven effectiveness ratings for any of the four active ingredients for any specific condition.
What side effects might I experience?
L-Arginine commonly causes abdominal pain, bloating, nausea, diarrhea, headache, insomnia, and flushing. Mucuna pruriens may cause diarrhea, flatulence, nausea, abdominal distention, vomiting, headaches, and insomnia. Maca may cause stomach pain. Hawthorn is generally well tolerated, though palpitations and tachycardia have occurred in some patients.
How many medications does this product interact with?
Altogether, these interactions span 519 individual medications — a substantial number. This is why it's critical to check your exact prescriptions with the tool on this page before you start.
