The Truth About Debloat and Detox Products

And Why They May Be Harming You

You’ve probably seen them—those viral ads claiming you’re carrying “up to 3 or 5kg of poo” and that a miracle detox or debloat tea or powder, or capsules or pills can fix it. As a health scientist and clinical nutritionist, I want to address these claims head-on.

Because the truth is: many of these so-called “detox” or “debloat” products are not only misleading—they can be dangerous.

🚫 The Myth: You’re Holding on to “5kg of Waste”

This figure is thrown around to shock and shame people into thinking they’re somehow unclean or in need of a purge. While yes, the digestive system can carry food waste as it’s processed through the colon, this amount varies constantly and is a normal part of digestion—not something that needs to be “flushed out.”

In fact, your body has incredibly efficient natural detoxification systems: your liver, kidneys, digestive system, and lymphatic system work around the clock to eliminate waste and toxins—no ‘fancy or viral product’ required.

🔬 Science check: The liver detoxifies harmful compounds via phase I and II metabolic pathways, converting fat-soluble toxins into water-soluble ones for excretion by the kidneys or bile .

🧪 What’s Really in These Products?

Many debloat and detox products contain herbal laxatives such as senna, cascara sagrada, or magnesium citrate. These ingredients stimulate the bowel and cause increased excretion—essentially, they make you poop. Fast.

This may create the illusion of weight loss—but it’s just water and waste, not fat. Worse, repeated use can lead to:

• Electrolyte imbalance

• Dehydration

• Digestive dependence

• Potential liver and kidney stress

🔬 One study found that chronic laxative use may alter the gut’s neuromuscular function, leading to long-term colonic inertia (slowed bowel movement) .

⚠️ Risks for Women—Especially If You’re Pregnant or Trying to Conceive

What worries me most is that many of these ads specifically target women—often in their reproductive years.

Stimulant laxatives may trigger uterine contractions or interfere with the absorption of essential nutrients like folate, iron, and calcium—nutrients that are crucial during pregnancy. In early pregnancy, before a woman may even realise she is pregnant, the embryo is rapidly developing and particularly vulnerable to nutrient deficiencies and toxic exposures.

For women trying to conceive, taking these products regularly may compromise overall nutritional status, gut health, and hormonal balance—all factors that affect fertility.

🔬 A study published in Birth Defects Research highlighted concerns over unregulated herbal laxatives and their potential teratogenic effects during early pregnancy.

💔 The Ethics of Fear-Based Marketing

These brands know exactly what they’re doing: they weaponise body image anxiety.

They prey on bloating—a normal, temporary sensation that can be influenced by food, hormones, stress, and gut health—and frame it as a sign you’re “toxic” or “blocked.” Then, they sell you the cure.

This kind of messaging is deeply unethical. It undermines people’s confidence in their bodies and encourages disordered eating and supplement overuse.

✅ What You Can Do Instead

If you feel bloated or sluggish, the solution isn’t to purge your system—it’s to support your body naturally. It is one thing to relieve bloating and to aid digestion, quite another to DE-bloat and DE-tox. These are what you can do to support your system:

• Increase dietary fibre (from fruits, vegetables, whole grains)

• Stay well hydrated

• Move your body regularly

• Prioritise gut-friendly foods like fermented vegetables, yoghurt, and prebiotic fibre

• Manage stress, which can greatly affect gut motility and bloating

And most importantly, give your body grace. You’re not a machine. You’re not “backed up” because you had a big meal. You don’t need a purge—you need nourishment.

💬 Your body isn’t broken—and you don’t need to be “detoxed.”

Instead of falling for fear-based fads, let’s focus on education, evidence-based nutrition, and kindness. Because true health isn’t about extreme cleanses—it’s about sustainable, supportive choices that work with your body, not against it.
