L-Arginine in Stallion Power: What the ED Trials Used and What One Gummy Holds
L-arginine is an amino acid the body uses to make nitric oxide, and it sits seventh in the Stallion Power blend. Trials in men with mild to moderate erectile dysfunction used 1,500 to 5,000 mg a day. By our label arithmetic, one gummy holds 5 mg or less, so the studies do not describe this product.

The basics01
What is L-arginine, and why is it in Stallion Power?
L-arginine is an amino acid, a building block of protein. Your body also uses it to make nitric oxide, a gas that helps blood vessels relax (MSKCC, Arginine).
That link to blood flow is why supplement makers add it to "male enhancement" products. An erection depends on blood flow, so the idea sounds tidy on paper.
Stallion Power lists L-Arginine seventh of nine lines in its 82 mg proprietary blend. The label prints no amount for it.
| Name on the label | L-Arginine |
|---|---|
| What it is | An amino acid the body uses to make nitric oxide |
| Where it appears | Place 7 of 9 in the 82 mg proprietary blend |
| Amount per gummy | Not listed; place 7 of 9, 5 mg or less |
| Amount used in research | 1,500-5,000 mg a day in ED trials |
| Strength of evidence | Trials in mild to moderate ED at gram doses; one gummy holds 5 mg or less |
| Marketed or traditional use | Amino acid the body uses to make nitric oxide, a blood-vessel relaxer. |
| Main caution | Can lower blood pressure; avoid with nitrates and ask first with sildenafil-type or blood-pressure medicines. |
The three-bottle picture is the brand's render of the pack. No photo of L-arginine itself was supplied.
The math02
How much L-arginine is in one Stallion Power gummy?
At most 5 mg, by our arithmetic. The label does not print the amount, so this is a ceiling worked out from the order of the lines, not a lab result.
A blend lists its parts from most to least by weight (21 CFR 101.36 (proprietary blends)). Caffeine is printed as 5 mg and sits fifth. L-arginine sits seventh, so it cannot weigh more than the caffeine.
Caffeine: 5 mg
The one printed amount in the blend, listed fifth.
L-arginine: place 7
Listed after caffeine, so no heavier than 5 mg.
Whole blend: 82 mg
The nine lines together. L-arginine is one small slice.

Dose vs research03
How does one gummy compare with the L-arginine doses in studies?
The gap is large. Trials in men with mild to moderate erectile dysfunction used 1,500 to 5,000 mg a day (Rhim 2019, arginine and ED meta-analysis). One gummy holds 5 mg or less.
Take the top of the gummy range, 5 mg, and the bottom of the trial range, 1,500 mg. The gummy is about one three-hundredth of the lowest studied dose.
The brass bar for L-arginine is the research range. The red bar is the ceiling for one gummy. Caffeine, tribulus and ashwagandha are on the same chart for comparison.
The evidence04
Does L-arginine help erectile dysfunction?
It may help some men with mild to moderate erectile dysfunction when taken at gram doses. A meta-analysis of arginine trials supports that narrow finding (Rhim 2019, arginine and ED meta-analysis). Mayo Clinic says arginine may help when the cause is physical (Mayo Clinic, L-arginine).
That is a statement about daily doses of 1,500 mg and up, usually in capsules or powder. It is not a statement about a gummy, and nobody has tested Stallion Power.
Reviews of supplement blends make the same point: most ED blends use amounts too small to match the research (Petre 2023, ED supplements review).
| Item | Amount | Source |
|---|---|---|
| Daily dose in ED trials | 1,500 to 5,000 mg | Meta-analysis (Rhim 2019, arginine and ED meta-analysis) |
| Stallion Power, per gummy | 5 mg or less (our arithmetic) | Label order (21 CFR 101.36 (proprietary blends)) |
| Printed amount on the label | Not printed | Supplement Facts |
| Gummies a day on the label | 1 | Suggested use |
Safety05
Is L-arginine safe with blood pressure medicine or nitrates?
Not automatically. L-arginine can lower blood pressure, and the effect can stack with nitrates, sildenafil and blood-pressure medicines (Mayo Clinic, L-arginine).
Nitrates and nitroglycerin matter most. Prescription sildenafil and tadalafil must not be combined with nitrates, because blood pressure can fall too far (MedlinePlus, Sildenafil) (MedlinePlus, Tadalafil). A supplement that acts on nitric oxide is a reason to ask first.
At 5 mg or less per gummy, the risk from this one ingredient is likely small. But the label asks anyone taking medications or with a medical condition to consult a doctor first, and we follow that line.
Do not stop, skip or reduce a prescribed medicine because you started a gummy. Tell your doctor or pharmacist about everything you take (FDA, Mixing medications and supplements).

When should erection trouble go to a doctor instead of a supplement?
Early, and before you rely on any supplement. Erectile dysfunction can be an early sign of heart disease or diabetes (NIDDK, ED symptoms and causes) (Mayo Clinic, Erectile dysfunction).
A clinician can check blood pressure, blood sugar and medicines, and can say whether L-arginine is a sensible thing to try at all. Lifestyle changes such as exercise and smoking cessation matter too (NIDDK, ED treatment).
- Trouble that lasts for weeks, or comes with chest pain or breathlessness
- Diabetes, heart disease or blood pressure on treatment
- Any nitrate or PDE5 prescription
- An erection lasting more than four hours: go to the emergency room now (NHS, Priapism)
Next08
Where does L-arginine fit among the nine Stallion Power ingredients?
It is the best-studied of the three late-blend herbs and amino acids, and still it sits at a tiny dose. Tribulus and horny goat weed follow it, each at 5 mg or less.
Compare it with horny goat weed and tribulus, or see the whole label on the supplement facts page.
FAQ09
L-arginine in Stallion Power: common questions
How much L-arginine is in Stallion Power?
The label does not print it. Because L-arginine is listed after the 5 mg caffeine, it can weigh 5 mg at most per gummy, by our arithmetic from the label order. That is a ceiling, not a measured amount.
Is the L-arginine in Stallion Power enough to matter?
Probably not by the standard of the studies. Trials in mild to moderate erectile dysfunction used 1,500 to 5,000 mg a day (Rhim 2019, arginine and ED meta-analysis), and one gummy holds 5 mg or less. No trial has tested the product itself.
Does L-arginine work for erectile dysfunction?
It may help some men with mild to moderate erectile dysfunction at gram doses, according to a meta-analysis (Rhim 2019, arginine and ED meta-analysis). Evidence for lower doses is not established. It is not a replacement for medical care or prescribed medicine.
Can I take L-arginine with sildenafil or nitroglycerin?
Ask a doctor first. Arginine can lower blood pressure, and the effect can add up with nitrates, sildenafil and blood-pressure medicines (Mayo Clinic, L-arginine). Nitrates and PDE5 drugs must not be combined (MedlinePlus, Sildenafil).
What are the side effects of L-arginine?
Stomach upset is the most common, and blood pressure can drop. People who have had a heart attack are advised to avoid it (MSKCC, Arginine). If you have a reaction, stop and call your doctor, as the label says.
Why does the label list L-arginine seventh?
A proprietary blend lists its parts from most to least by weight (21 CFR 101.36 (proprietary blends)). Seventh place, after 5 mg of caffeine, caps L-arginine at 5 mg. The order is the only clue the label gives.
