HelloPharmacist Scorecard of Warrior Endurance by WarriorForce

Our pharmacy team’s full take, with four database checks built into the cards below — a summary of what is known, not a grade of the product itself.

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 1 of its 1 active ingredient.
  • No proprietary blends here — you can verify the dose of every single component.

Warrior Endurance contains one active ingredient: nopal cactus (also called prickly pear cactus), a traditional plant used in some cultures for blood sugar support and other purposes. The capsule itself is made from VeganCap(TM), a plant-based capsule material.

Does it work?

Moderate evidence
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
Moderate

Some clinical evidence supports this product's ingredients for its stated purpose, but it isn't conclusive.

Why this rating?
  • The label markets this product for: blood sugar control and endurance support.
  • We looked for evidence on: Diabetes, Hangover, Hypercholesterolemia, Metabolic syndrome, Glycemic control, Athletic performance — and 1 related terms.
  • The strongest evidence on file: Prickly Pear Cactus is rated "Possibly Effective" for Diabetes (Natural Medicines).
  • Also on file: Prickly Pear Cactus is rated "Insufficient Reliable Evidence To Rate" for Familial hypercholesterolemia, Hypercholesterolemia, Hangover, Metabolic syndrome.

Nopal cactus is rated possibly effective for diabetes based on the evidence we hold. For age-related cognitive decline, benign prostatic hyperplasia (enlarged prostate), indigestion, and high cholesterol (including familial hypercholesterolemia), the evidence is insufficient to rate whether it works.

If you're considering this product for one of those other uses, talk with your pharmacist about what the science actually shows.

The evidence, ingredient by ingredient Prickly Pear Cactus

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 1 of the 1 matched ingredient.
  • Pregnancy & breastfeeding safety ratings cover 1 of 1.
  • General safety write-ups exist for 1 of 1.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

Nopal cactus is generally well tolerated when taken by mouth. The most common side effects are mild: abdominal fullness, indigestion, diarrhea, and nausea.

Rare side effects include headache, insomnia, and dizziness—a clinical study of 41 people saw two with headache, one with dizziness, and one with insomnia. Cases of obstruction in the colon and rectal injury have been reported, but only in people who ate a very large number of prickly pear fruits; these are extremely rare.

Because the dried cactus swells when it absorbs water, it can increase stool volume and frequency. There isn't enough safety data to know whether nopal cactus is safe in supplement amounts during pregnancy or while breastfeeding.

Talk with your doctor or pharmacist before using it if you're pregnant or nursing.

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

Why this rating?
  • 1 of the 1 matched ingredient can interact with medications — Prickly Pear Cactus.
  • The most serious interaction on file is rated Moderate.
  • Some involve high-stakes drug classes: diabetes medications.
  • For scale: 86 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 taking Warrior Endurance, double-check any antidiabetes drugs you use with the medication search tool on this page. Nopal cactus can increase the risk of low blood sugar when combined with these medications.

The bottom line

Scorecard at a glanceFully disclosed formula with some supporting evidence for its stated purpose. Moderate medication interactions have been identified, and safety information is well characterized.

Warrior Endurance may be worth considering if you have type 2 diabetes and want to explore nopal cactus as an add-on—the evidence suggests it might help. But if you take any antidiabetes medication, check your specific drugs with our tool first and monitor your blood sugar closely.

Those who are pregnant, breastfeeding, or have a history of bowel obstruction should talk with their pharmacist before starting.

General Statements

What is a True Warrior(TM)? It is easy to be an aggressive, selfish, mean, assh%&e. Just combine a bad attitude with some "roids" or take legal substances/chemicals that imbalance your body and hormones. Then you are just a Barbarian. A True Warrior(TM) is kind, unselfish, caring, and lives consciously by a code of ethics/honor such as bushido (Samurai), or Chivalry (Knights), yet at the same time is completely willing to stand up for those who need it, & unleash a fury of appropriate force, should battle be required. A True Warrior(TM) is conscious of all the choices made in life, and is open-minded. The world needs more True Warriors(TM). Are you are True Warrior(TM)? - Dr. Jameth Sheridan (D.H.M.) Doctor of Holistic Medicine

Nopal is so powerful and versatile it has even been shown to greatly lessen the effects of a hangover when taken before, during, and after alcohol consumption. Does NOT make you less drunk (don't drink and drive or do anything else stupid, reckless and deadly!). Don't use this as an excuse to drink.

10/2017 12290 VR

Background Information: Nopal Cactus has been used for thousands of years by natives of Mexico and the American southwest as a food and powerful medicine.

Heat Shock Proteins (HSPs) are proteins synthesized by the body in response to physical stress and heat. They allow the body to better adapt to physical extremes. HSPs usually form in about 2-3 hours from physical stress. Nopal can reduce this time to 10-15 minutes, allowing for much greater resistance to stress, more endurance, more stamina, and faster recovery.

Additional benefits include nutritional support of: Blood Sugar - Insulin - Cholesterol - Bowel - Liver & Im mune System Functions; - Timed Release of Nutrients - Extended Hydration (when consumed with sufficient fluids)

Promotes Heat Shock Proteins for: Endurance - Stamina - Hangover Recovery
