Blood Pressure Medicine and Supplements: Ask First
Blood pressure medicine and supplements can interact, because some supplement ingredients lower pressure or change how the body handles a drug. Tell your doctor or pharmacist about every supplement before you start. L-arginine is one example, and Stallion Power lists it in its 82 mg blend.

The question01
Is it safe to mix blood pressure medicine and supplements?
It depends on the supplement and the medicine, so ask your doctor or pharmacist before you mix them.
FDA says supplements can change how a medicine works, and the change can go either way (FDA, Mixing medications and supplements). NIH adds that natural does not mean safe, and that supplements are not approved before they are sold (NIH ODS, Dietary Supplements: What You Need To Know).
A supplement is never a substitute for a prescription. Do not stop or change a dose on your own. Bring the question to the person who prescribed it.
The ingredients02
Which supplement ingredients can change blood pressure?
L-arginine is the best known. Mayo Clinic says blood pressure may drop when it is taken with nitrates, sildenafil or blood pressure drugs (Mayo Clinic, L-arginine).
Memorial Sloan Kettering also lists lower blood pressure and stomach upset as arginine effects (MSKCC, Arginine). Other lines in a male enhancement blend raise their own questions.
| Label line | Why it comes up | Source |
|---|---|---|
| L-arginine | Can lower blood pressure, mainly with nitrates, sildenafil or blood pressure medicine | (Mayo Clinic, L-arginine) |
| Horny goat weed extract | Advice to avoid with heart disease; rhythm case reports exist | (MSKCC, Epimedium (horny goat weed)) |
| Green tea extract | May lower the level of nadolol, a blood pressure drug | (NCCIH, Green Tea) |
| Caffeine (5 mg) | Small next to the 400 mg a day FDA gives for most healthy adults | (FDA, How much caffeine is too much?) |
The dose03
How much L-arginine is in one Stallion Power gummy?
The label does not say. It prints an 82 mg blend total and lists L-arginine seventh of nine lines.
Caffeine sits fifth and is printed as 5 mg. Lines are listed from most to least by weight (21 CFR 101.36 (proprietary blends)), so each line after caffeine weighs 5 mg or less. That is our arithmetic from the label order, not a lab test.
Trials of L-arginine for erectile problems used 1,500 to 5,000 mg a day (Rhim 2019, arginine and ED meta-analysis). One gummy is far below that.

What should you ask your doctor or pharmacist?
Ask three things: does any line interact with my medicines, does my heart or blood pressure history rule it out, and what should I watch for?
Bring the label
Photograph the Supplement Facts and the warning side. The label itself asks anyone taking medications to consult a doctor first.
Say what is unknown
FDA has found hidden drugs in some male enhancement products (FDA, Tainted sexual enhancement products). We have not tested this gummy and no lab report is published. Your pharmacist should hear that.
If you feel dizzy, faint or unwell after starting a supplement, stop it and call your doctor. The side effects page lists the warning signs, and who it is for covers who should skip it.
Next step05

FAQ06
Stallion Power questions people ask
Can I take L-arginine with blood pressure pills?
Ask your doctor first. Mayo Clinic says arginine may lower blood pressure further when combined with blood pressure medicines, nitrates or sildenafil (Mayo Clinic, L-arginine). Your doctor may want to check your readings or suggest another approach.
Does the caffeine in a gummy raise blood pressure?
Stallion Power prints 5 mg of caffeine per gummy. FDA gives 400 mg a day as a level most healthy adults tolerate (FDA, How much caffeine is too much?). If you are sensitive to caffeine or have a heart condition, still ask your doctor.
What if I feel dizzy after starting a supplement?
Stop the supplement and call your doctor. The Stallion Power label says to discontinue use and consult your doctor if any adverse reactions occur. Sit or lie down first, and get emergency help if you faint.
