Detox products sell immunity, and a 2026 IV recall shows what can go wrong

Key takeaways

• In 2026, injectable glutathione made with a dietary-supplement-grade ingredient sickened more than 25 people in at least four states, and one needed intensive care for shock, the CDC reported¹.
• A Texas compounding pharmacy recalled vials that included a glutathione, vitamin C and zinc mix called “Tri-Immune Boost” in September 2026, after nine reports of reactions such as fever, chills and chest pain³.
• Your liver and lungs double as immune organs: in mouse studies, liver immune cells catch gut bacteria that slip into the blood, and lung cells sweep out and attack what you breathe in⁸⁹¹⁰.
• In 2020, the FTC charged that Teami sold its detox teas with unsupported claims that they could prevent colds and flu and fight cancer; the company paid $1 million of a $15.2 million judgment¹².
• Not smoking and drinking less have far better evidence for protecting your immune defenses than any cleanse, drip or tea¹⁰¹¹¹³.

This year’s alarm came from Texas. In July 2026, the state’s health department alerted the CDC to a cluster of patients from one wellness clinic, all sick after the same kind of drip¹. It held glutathione, an antioxidant that some wellness clinics infuse into a vein¹.

By late August, the FDA knew of at least 30 people with fever, chills, pain, dizziness or signs of shock after IV glutathione, some of them hospitalized². It traced the problem to one lot of supplement-grade glutathione powder from a supplier called Medisca, which compounding pharmacies (businesses that mix custom drugs) had used to make injections².

By mid-September, the CDC’s tally had passed 25 patients, spread across at least four states: Texas, Washington, Florida and New York¹. Three or more had been admitted to a hospital. One became critically ill, with shock and blood that clotted abnormally, and needed intensive care¹. When we checked in late October 2026, the CDC page still carried its mid-September update, and the FDA’s notice still said the agency was actively investigating¹².

Then came the product name that sums up the market. On September 9, a Texas compounding pharmacy, Centric Compounding, recalled six lots of vials, including one called “Tri-Immune Boost,” a blend of glutathione, vitamin C and zinc³. Some had gone straight to patients’ homes through delivery services, and the vials drew nine reports of reactions³. The CDC’s hospital counts describe IV glutathione cases overall, and its page doesn’t tie them to these vials¹.

The likely culprit was endotoxin, a toxin from bacteria¹³. Injected, it can cause fever, chills, a drop in blood pressure and, at worst, death, the FDA warns². Endotoxin does its damage by provoking the immune system³. Products sold to strengthen immunity had set off a dangerous immune alarm instead.

Worry about toxins is reasonable. Below, we cover how your body clears and defends at once, what “detox for immunity” products have shown, and what lowers real exposures.

Your cleanup organs are also immune organs

Detox ads treat your liver as a filter that clogs. Immunologists see more.

The liver gets blood straight from the gut, along with its own arterial supply. A 2013 review in Nature Immunology called it a “frontline immunological organ,” packed with immune cells that pluck germs out of passing blood⁸.

The liver also has to hold back. It sees a constant stream of harmless molecules from food, and it must avoid attacking them⁸.

A 2014 study in mice, published in Science Translational Medicine, showed why that matters⁹. Immune cells in the liver called Kupffer cells acted like a firewall, catching gut bacteria that leaked into the bloodstream⁹. When the mice’s livers were damaged, more bacteria got through, and immune reactions flared outside the gut⁹. People with a fatty liver disease called NASH showed signs of the same pattern⁹.

Your lungs work the same double shift. Tiny hairlike cilia sweep mucus and trapped particles out of the airways, and immune cells called alveolar macrophages serve as the lungs’ first cellular defense against germs¹⁰.

Kidneys, the lymphatic system and skin share the cleanup work¹⁴. Our articles on the body’s own detox, infrared saunas, circulation, and chelation and colonics cover those systems and the sweat sessions, foot baths and procedures sold to speed them up.

The point for immunity is simple. When you protect these organs, you protect your defenses.

Glutathione is real biology, but the drip is a different story

Glutathione deserves a fair hearing, because the science behind it is real. It’s an antioxidant found in your blood cells and in the cells lining your mouth and lungs⁶¹⁰. It helps cells cope with oxidative stress, a kind of chemical wear¹⁰.

In lungs exposed to heavy drinking, glutathione runs low, and alveolar macrophages work poorly¹⁰. In animal studies, restoring glutathione improved how those cells worked¹⁰. That’s the kernel of truth that marketing builds on.

Pills. In a six-month trial at Penn State, 54 nonsmoking adults took 250 or 1,000 milligrams of oral glutathione a day, or a placebo⁶. Blood levels rose in both dose groups. At the high dose, levels rose 30% to 35% in red blood cells, plasma and lymphocytes, a type of white blood cell⁶.

The high dose also more than doubled the activity of natural killer cells, a type of immune cell, at three months compared with placebo⁶. A month after people stopped, levels had mostly fallen back to where they started⁶.

Two cautions apply. The trial measured immune markers, not colds or infections. And it was supported by Kyowa Hakko, the company that makes the glutathione ingredient tested⁷. It’s a promising early signal from one company-funded study, not proof of fewer illnesses.

Drips. IV glutathione skips the gut and goes straight into a vein. We found no evidence in the federal and research sources we checked that it improves immune function in healthy people.

The FTC has already acted against one IV seller. In 2018, it brought its first case over IV vitamin “cocktails,” against a Texas company called iV Bars that charged $100 to $250 a session⁵. The FTC said the company claimed the drips could treat serious diseases such as cancer, multiple sclerosis and congestive heart failure⁵. As part of the case, iV Bars emailed customers that studies hadn’t shown its Myers Cocktail to treat any disease⁵.

The 2026 recalls repeated a 2019 warning

None of this is new to the FDA. In June 2019, it warned compounders about glutathione powder labeled “Caution: Dietary Supplement” from a repackager in Alabama⁴.

Seven clinic patients had received 1,400 milligrams each by IV⁴. Within minutes, they had nausea, vomiting, dizziness, chills and body aches, and one went to the hospital with low blood pressure and trouble breathing⁴. FDA testing found too much endotoxin in every sample, some up to five times the limit⁴.

Seven years later, the same kind of ingredient caused the same kind of harm. In August 2026, the FDA repeated that supplement-grade glutathione doesn’t belong in injections, because it may carry contaminants such as endotoxin².

The lesson goes beyond one compound. A wellness clinic, a med spa or a home delivery service may not tell you which grade of ingredient went into your vial. “The Same Vitamin Comes in Many Forms. Only Some Differences Matter” explains why that matters.

Detox teas promise flu protection, but the FTC disagreed

Detox teas are cheaper and easier to find than IV clinics. One major federal case involved Teami, a Florida company that sold a “30 Day Detox Pack” and other teas¹².

In 2020, the FTC charged that Teami’s marketing promised far more than tea can deliver: fast weight loss, fewer migraines, unclogged arteries, a fight against cancer cells and protection from colds and flu¹². Paid influencers helped spread those messages, a story told in “How to judge a cup of herbal tea, which is gentle but not automatically harmless.”

Teami and its owners settled. They faced a $15.2 million judgment, suspended after they paid $1 million for consumer refunds¹².

Some detox teas contain laxative herbs, as our colon cleanse article explains, along with who should avoid them. NIH’s National Center for Complementary and Integrative Health (NCCIH) warns that laxatives can cause diarrhea, dehydration and poor absorption of nutrients¹³. Losing fluids won’t help you fight a cold.

Charcoal and juice cleanses can bind or block the wrong things

Activated charcoal earns its place in emergency medicine. It grabs certain chemicals inside the gut, which is why it’s used for some poisonings, and even then only as a big dose given fast¹⁴.

A black lemonade or a detox capsule has a smaller reach. Charcoal works only inside your digestive tract, so it can’t clean your blood. That’s the liver’s job¹⁴.

What it can grab includes your medicines and nutrients. OhioHealth, an Ohio hospital system, suggests checking with your doctor before using it if you take blood pressure pills or birth control, and spacing charcoal at least an hour from any medicine or supplement¹⁴. Overdo it, and you risk vomiting, constipation or even a blocked bowel¹⁴.

Store-bought charcoal is not a home poisoning kit. If you think someone has been poisoned, call Poison Help at 1-800-222-1222 or head to the closest emergency room¹⁴.

Juice cleanses are often sold as an immune reset. NCCIH’s fact sheet on detoxes, last updated in March 2025, lists no study showing that one improves immune function¹³. Its summary of the research is blunt: few studies, mostly low quality, and none on long-term effects¹³.

The fact sheet does list risks, and one of them targets the very people most worried about immunity. Juice that hasn’t been pasteurized can make people seriously ill, and the risk is highest for children, older adults and anyone whose immune system is weakened¹³. Juices heavy in oxalate, from leafy greens or beets, can be risky for people prone to kidney stones¹³. Our article on what detox really means describes kidney failure cases tied to juice cleanses.

Going without food brings its own effects. NCCIH lists headaches, fainting, weakness and dehydration from fasting, and dangerous salt imbalances from days of only water or herbal tea¹³. If cleanses, fasting or laxatives have become a way to control your weight, the National Alliance for Eating Disorders helpline can help at 1-866-662-1235, staffed weekdays from 9 a.m. to 7 p.m. Eastern¹⁵.

What weakens immune defenses, and what you can change

If detox products don’t strengthen immunity, what weakens it? Two common exposures have far stronger evidence than any “toxin” a cleanse claims to remove.

Smoking. The U.S. Surgeon General’s 2014 report concluded that smoking compromises the immune system¹¹. Smoke harms immune cells, so they fight viruses and bacteria less well¹¹. Our guide to quitting tobacco covers the methods with the best track record.

Heavy drinking. A review in NIAAA’s journal, Alcohol Research: Current Reviews, describes what long-term drinking does to the lungs¹⁰. Cilia lose their ability to speed up when germs are inhaled, and alveolar macrophages get worse at eating invaders¹⁰. People with alcohol use disorder develop acute respiratory distress syndrome, a life-threatening lung failure, two to four times as often as other people¹⁰.

That review also explains the glutathione link. Long-term drinking drains glutathione in the lungs¹⁰. By our reading, protecting that supply starts with drinking less, not with a drip.

Dirty air. Wildfire smoke, gas burners and indoor flames reach the same lung defenses. Our companion article on air quality explains how to read the Air Quality Index and clean the air at home.

Lead and other metals. These are real toxins, and labs can measure them. Our article on children’s blood lead shows how cutting exposure at the source did what no detox product has.

The detox claim check

Use this table when a product promises to detox you into better immunity. Compare what’s claimed with what your body already does.

The claim	What your body already does	What testing shows	Risk to weigh
“This IV drip boosts your immunity”	Liver and lung immune cells catch germs every day810	One IV seller’s own notice said studies hadn’t shown benefit for any disease5	Endotoxin reactions from supplement-grade ingredients124
“Glutathione detoxes you”	Glutathione is already in your cells; heavy drinking drains it in the lungs610	Oral pills raised levels and one immune marker in a company-funded trial67	Injected versions caused fever, chills and shock-like illness12
“This tea flushes toxins and prevents flu”	Liver and kidneys clear waste around the clock14	FTC charged that Teami’s flu, cancer and artery claims lacked support12	Laxative effects: diarrhea and dehydration13
“Charcoal pulls toxins out”	Charcoal acts only inside the gut14	Used in hospitals for some poisonings, in large, fast doses14	Can block medicines, including birth control, and nutrients14
“A juice cleanse resets your immune system”	The liver acts as a firewall for gut bacteria9	Few, low-quality detox studies; none on immune outcomes in NCCIH’s summary13	Unpasteurized juice is risky with a weak immune system13

How the evidence rates

IV “immune” or glutathione drips help healthy people	Not enough evidence	No supporting trials found; an IV seller told customers studies hadn’t shown benefit5
Injections made with supplement-grade glutathione are safe	Evidence says no, or unsafe	Endotoxin reactions in 2019 and 2026124
Activated charcoal detoxes the body outside a poisoning	Not enough evidence	It acts only inside the gut and can’t clean the blood14
Smoking weakens immune defenses	Strong evidence	The Surgeon General’s 2014 conclusion11
Heavy drinking weakens lung defenses	Strong evidence	Human and animal research on cilia, macrophages and lung failure10

The urge to cleanse is sound, and point it at the source

Natural health has long held that what goes into the body matters, and that less of the wrong things is better. That instinct fits the science. Your liver and lungs are busy every minute, sorting what to clear, what to tolerate and what to attack⁸⁹¹⁰.

Where the market goes wrong is the direction of effort. Detox products add something: a tea, a powder, an infusion. The changes with the best evidence take something away: smoke, heavy drinking, polluted air, lead.

That’s also the gentler path. It asks your organs to do less, instead of asking a product to do more.

When to get help. After any wellness injection, call a provider promptly for fever, chills, severe body aches, nausea or dizziness, and get emergency care for trouble breathing, fainting or signs of shock¹. Call Poison Help at 1-800-222-1222 about a possible poisoning¹⁴. Report reactions to wellness drugs or supplements through FDA’s MedWatch program². Before starting charcoal, a cleanse or a laxative tea, ask your clinician or pharmacist how it fits with your medicines¹⁴.

Questions readers ask

The bottom line

“Detox for immunity” combines two ideas that sell well: purity and protection. Your body already delivers both. The liver catches gut bacteria that reach the blood, the lungs sweep out and attack what you breathe, and these organs clear waste without help from a bottle.

The products sold in that space have little evidence, and some have caused harm, most recently contaminated IV glutathione that sent people to the hospital. The steps that protect your defenses are less exciting and better tested: don’t smoke, drink less, breathe cleaner air and keep known toxins out at the source.
