Safety

Stallion Power Side Effects: Caffeine, Sugar, Herbs and Medicines

Quick answer

The label does not list any side effects and says to stop use and consult your doctor if any adverse reaction occurs. We found no trial of the gummy, so no known rate exists. The concerns come from the parts: 5 mg of caffeine, 3 g of added sugar, sorbitol, and rare liver reports for green tea extract and ashwagandha.

What the label says01

The label's only safety wording

It is short, and it leaves the rest to you and your doctor.

The Stallion Power label does not list any side effects. It prints one warning and a few handling notes.

The warning, as printed

If pregnant or nursing, taking medications or with a medical condition, consult your doctor before using. Discontinue use and consult your doctor if any adverse reactions occur. Keep out of the reach of children.

A label with none listed does not mean there are none. The sales page goes further and calls the product “totally safe” in its own words. We quote that line to check it, not to repeat it. Safety for a supplement is not tested before sale. The FDA does not approve supplements before they are marketed (FDA, Q&A on dietary supplements).

We found no study of this gummy, so no adverse-event rate exists for us to report. What we can do is look at the parts. The table below sets each concern next to the number on the label.

Where side effect concerns could come from
SourceAmount per gummyPossible concern
Caffeine5 mg printedJitters or poor sleep in sensitive people (FDA, Caffeine)
Green tea extractNot printed; at most 19.25 mg by label arithmeticNausea; rare liver injury reported with extracts (NCCIH, Green tea) (NIH LiverTox, Green tea extract)
AshwagandhaNot printed; at most 5 mgRare liver injury reported with products (NIH LiverTox, Ashwagandha)
Added sugar3 g (6% DV)Teeth, blood sugar (ADA MouthHealthy, Diet and dental health)
SorbitolNot printedLoose stools in large amounts (21 CFR 184.1835, Sorbitol)
Whole blend82 mgMedicine interactions: ask a pharmacist

Ceilings come from the descending-order rule for proprietary blends (21 CFR 101.36, Supplement Facts). They are arithmetic on a printed label, not a lab test.

Caffeine02

Caffeine: small on paper, one unknown

The label puts caffeine at 5 mg a gummy. For scale, a 12 oz green tea has about 37 mg, and the FDA cites 400 mg a day as an amount not generally associated with negative effects for most healthy adults (FDA, Caffeine). A 5 mg dose is well below both.

The unknown is green tea extract. It sits in line four, and green tea carries caffeine. The label does not say whether the extract is decaffeinated or how much caffeine it adds. So the true total could be higher than 5 mg. If you react to a cup of tea, take this seriously.

  • Count your coffee, tea, energy drinks and pre-workout powders first.
  • If you feel shaky, have a racing heartbeat or sleep badly, stop and talk to your doctor.
  • If you have a heart rhythm condition, ask before starting.

Timing matters for some people. Our how to use page covers whether to take it earlier in the day.

Liver03

Green tea extract and ashwagandha: the liver reports

Rare, serious, and worth knowing about before you start.

NIH LiverTox says green tea extract is linked to clinically apparent acute liver injury, including cases of acute liver failure (NIH LiverTox, Green tea extract). Those cases involved large amounts, about 800 mg to 1.86 g of extract a day. A Stallion Power gummy can hold at most 19.25 mg of green tea extract by label arithmetic, so it sits far below those amounts. Far below is not the same as safe for everyone, and the label does not print the real figure.

For ashwagandha, LiverTox says it has not been implicated in enzyme elevations in clinical trials, but liver injury has been reported with products (NIH LiverTox, Ashwagandha). Typical product doses run 150 to 600 mg, and the gummy can hold at most 5 mg of it.

Stop and call a doctor

Yellow skin or eyes, dark urine, pale stools, strong stomach pain on the upper right side, or deep tiredness are signs to stop use and get checked. Tell the doctor which supplements you use.

If you already have liver disease, drink heavily or take medicines that tax the liver, talk to your doctor before any new herbal product. Our guide to supplements and medications explains what to bring to that talk, and the ashwagandha page covers its sources in more detail.

Sugar and sorbitol04

Sugar, teeth and sorbitol

A gummy has 3 g of total sugar, all of it added (6% of the Daily Value). The other ingredients start with corn syrup and cane sugar. Over a 30-day bottle that is 90 g of added sugar. The Dietary Guidelines advise keeping added sugars under 10 percent of calories, about 50 g on a 2,000-calorie diet (Dietary Guidelines, Added sugars). The AHA suggests no more than 150 calories of added sugar a day for men (AHA, Added sugars). One gummy is a small share of that. It adds up if you also drink sweet drinks.

The ADA notes that bacteria in plaque make acids after you eat or drink sugar, and the acids attack enamel (ADA MouthHealthy, Diet and dental health). A sticky gummy stays on teeth. Brushing after it is a sensible habit, and it is not a label direction.

If you have diabetes, 3 g is small but not zero. Count it, and tell your doctor. Sorbitol also appears on the label. US rules require a laxative warning on foods that could lead to 50 g of sorbitol a day (21 CFR 184.1835, Sorbitol). One gummy likely holds far less, yet the label gives no amount, so loose stools would be the first thing to watch for.

Medicines05

Medicines and conditions: ask before you start

Keep taking every prescribed medicine. Do not stop one to try a supplement.

Nitrates, such as nitroglycerin, and erectile dysfunction drugs, such as sildenafil, both lower blood pressure. MedlinePlus says not to take sildenafil with nitrates (MedlinePlus, Sildenafil). A supplement is not a drug, but the label also lists L-arginine, and a pharmacist needs to see the label before you add it to either kind of medicine.

The same ask-first rule applies to blood thinners, blood pressure and heart medicines, diabetes drugs, sedatives and thyroid drugs. We found no interaction study for this gummy, so we cannot say which combinations are safe. A pharmacist can check each of the nine lines against your list in minutes. Our medicines guide has a short list of questions to ask.

Seek emergency care for chest pain, fainting, an erection lasting longer than four hours, or sudden vision or hearing loss.

The category risk06

Hidden drugs in enhancement products

This is a risk of the category, not a finding about Stallion Power. The FDA has found sildenafil and tadalafil, not listed on the label, in products sold for sexual enhancement (FDA, X10 hidden-drug notice) (FDA, Wild Sexx hidden-drug notice). The NCCIH also warns that products sold for sexual enhancement may contain prescription drugs not listed (NCCIH, Using Dietary Supplements Wisely).

We have no lab result for Stallion Power, and the label names no testing lab. So we cannot say it is free of hidden drugs, and we have no evidence that it has any. What we can say is to buy only through the official order route, check the seal under the cap, and report any odd reaction. Read more in tainted enhancement products and the lot check page.

If something happens07

What to do if you have a reaction

  1. Stop taking it

    The label says to discontinue use and consult your doctor if any adverse reactions occur.

  2. Get help if it is serious

    Emergency care for chest pain, fainting, trouble breathing or an erection lasting more than four hours.

  3. Write down the details

    Note the date you started, the symptoms, the lot number, and everything else you take.

  4. Report it

    Tell your doctor, report it to the FDA through MedWatch, and contact the order desk at +1 (302) 200-3480 or [email protected].

If you want your money back, the sales page offers a “60-Day Money-Back Guarantee”. You must send back all bottles within the window and pay return shipping. The guarantee page has the steps.

FAQ08

Stallion Power questions people ask

What are the possible side effects of Stallion Power?

The label lists none. It says to discontinue use and consult your doctor if any adverse reaction occurs. No trial of the gummy exists, so no rate is known. The concerns we can name come from the parts: caffeine, sugar, sorbitol, and liver reports linked to green tea extract and ashwagandha products.

Can Stallion Power cause headaches or jitters?

It may in people who are sensitive to caffeine. The label prints 5 mg per gummy, which is small (FDA, Caffeine). The green tea extract line may add caffeine, but no amount is printed. If you get headaches, jitters or poor sleep, stop and ask a doctor or pharmacist.

Can Stallion Power upset the stomach?

Possibly. The NCCIH says green tea extract supplements can cause nausea (NCCIH, Green tea), and the gummy also contains sorbitol, which in large amounts can act as a laxative. A single gummy likely holds far less than that, but the label gives no figure. Stop if you have ongoing stomach trouble.

Can Stallion Power raise heart rate or blood pressure?

The label does not say. Caffeine at 400 mg a day is not generally linked to harm in most healthy adults (FDA, Caffeine), and one gummy holds 5 mg. But the blend has several herbs, and no trial tested the mix. If you have heart disease or high blood pressure, ask a doctor before you start.

What should I do if I have a bad reaction?

Stop taking it and contact your doctor, as the label directs. For chest pain, fainting, trouble breathing, a lasting erection of more than four hours, or sudden vision or hearing loss, get emergency care. Hold on to the bottle and write down the lot number. Then tell the seller at +1 (302) 200-3480.

How do I report a supplement reaction to the FDA?

Use the FDA's MedWatch program, online or by phone. Have the product name, the lot number from the bottle, the date you started, your symptoms and any medicines you take. Reports help the FDA spot patterns, because it does not approve supplements before they are sold (FDA, Q&A on dietary supplements).
