zuPoo Review 2026: Misleading Claims
Skip this one. — Misleading
-
"You may be carrying pounds of trapped waste in your colon"
A healthy colon does not store weeks of old food. This is a debunked detox myth, not physiology.
Examine.com colon cleanse myths overview -
"Cascara Sagrada is a safe, gentle natural laxative"
The FDA removed cascara sagrada from its approved OTC laxative ingredient list in 2002 for lacking safety data.
FDA OTC laxative final rule, 2002 -
"Milk thistle supports liver detox in this formula"
Label lists only 10mg milk thistle. Clinical studies use 70-200mg of silymarin to see any liver enzyme effect.
-
"$35 for a natural, research-backed cleanse"
Main active ingredient is magnesium citrate, a laxative sold alone for a few dollars at any pharmacy.
Consumer advice
If you're constipated, a $5-8 bottle of magnesium citrate or a standard fiber supplement will do the same job as zuPOO's actual active ingredient, without the added cascara sagrada or aloe ferox — both anthraquinone laxatives with dependency and electrolyte-imbalance risks on repeated use. Don't buy into the "pounds of trapped waste" or "detox" framing — that's not how digestion works. If you use it, don't exceed the recommended 7-day cycle, stay hydrated, and skip it entirely if you have IBS, IBD, or take medications affected by electrolyte shifts. Talk to a doctor before repeated "cleanses" every 4-6 weeks — chronic stimulant laxative use can itself cause the sluggish bowel function it claims to fix.

Safety & side effects

Magnesium
Magnesium from food poses no health risk in healthy people, because the kidneys clear the excess. High doses from supplements or medications can cause diarrhea, nausea and abdominal cramping, and very high doses can lead to toxicity.
Possible side effects
- High doses from supplements or medications can cause diarrhea, nausea, and abdominal cramping.
- Magnesium carbonate, chloride, gluconate, and oxide are the forms most commonly reported to cause diarrhea.
Serious risks
- Very high doses can lead to magnesium toxicity, with low blood pressure, vomiting, difficulty breathing, irregular heartbeat, cardiac arrest and other signs.
- A few cases of fatal hypermagnesemia have been reported.
- Very large doses of magnesium-containing laxatives and antacids have been associated with magnesium toxicity.
- The risk of toxicity increases with impaired kidney function or kidney failure.
Avoid or ask a doctor first if
- People with impaired kidney function or kidney failure face higher risk of magnesium toxicity.
- People taking medications regularly should discuss their magnesium intake with their health care providers.
Medication interactions
- Magnesium may interact with oral bisphosphonates, tetracyclines, and quinolone antibiotics.
- Some medications, including diuretics and proton pump inhibitors, can affect magnesium status.
Upper limit: 350 mg a day for adults 19+. This label lists 200mg.

Ginger
NCCIH says ginger has been used safely in many research studies when taken by mouth as a supplement. It lists some side effects and advises talking with a health care provider if you take medicine or are pregnant.
Possible side effects
- Taken by mouth, ginger can cause abdominal discomfort, heartburn, diarrhea, and mouth and throat irritation.
Avoid or ask a doctor first if
- If you're considering ginger while pregnant, consult your health care provider, as with all herbal supplements.
- Little is known about whether ginger is safe while breastfeeding.
Medication interactions
- If you take any medicine, talk with your health care provider before using ginger or other herbal products, because some herbs and medicines interact in harmful ways.
Milk Thistle
NCCIH says milk thistle taken by mouth appears to be well tolerated, and the most common side effects are digestive. It also points to product quality problems, possible allergic reactions, and drug interactions, and says little is known about use in pregnancy or breastfeeding.
Possible side effects
- Milk thistle taken orally appears to be well tolerated. The most common side effects are digestive symptoms.
Serious risks
- Milk thistle may cause allergic reactions, especially in people allergic to related plants.
- Some supplements have silymarin amounts far from the label, or contain pesticides, microorganisms, or mycotoxins.
Avoid or ask a doctor first if
- People allergic to related plants such as ragweed, chrysanthemum, marigold, and daisy are named as more likely to react.
- Little is known about whether milk thistle is safe during pregnancy or breastfeeding.
Medication interactions
- People taking any medicine should talk with a health care provider before using milk thistle, since some herbs and medicines interact in harmful ways.
