This is not a personal attack. I’ve watched people suffer because of this.
I’ve been pitched (many times) to “join the movement,” promised freedom if I sell shakes.
I blocked people. I’ll never give clients something that could put their health at risk just to
make money.
Beyond the sales tactics, my biggest concern is the health risk.
8 Hidden Dangers of Herbalife with sources
1) Liver Problems
Multiple medical case series from Israel, Switzerland, Spain, Iceland/US link Herbalife use
with acute hepatitis and liver failure. Examples: Israel’s hospital-led series reported biopsy-
proven hepatitis and severe outcomes; Switzerland reported severe cases; Spain kept logging new cases nationally.
2) “Re-challenge” Risk
The Israeli Ministry of Health investigation documented patients who improved after
stopping Herbalife but became ill again after restarting a classic signal in causality assessment.
3) ☠Toxic Contamination
Independent analyses have reported bacterial contamination and other issues in certain
Herbalife products. A peer-reviewed report found Bacillus subtilis contamination; the
bacterial supernatant showed dose-dependent hepatotoxicity in HepG2 cells.
(Contamination can vary by batch.)
4) Kidney Stress (especially if you already have kidney disease)
Many shakes are high in protein, potassium, and phosphorus; some products add caffeine.
CKD patients are typically advised to limit protein, potassium, and phosphorus, and to watch stimulants/blood pressure. Good summary here on Herbalife & kidneys + CKD cautions.
5) Hormone & Metabolism Impact (nuanced)
Some botanicals (e.g., soy isoflavones) can act like weak phytoestrogens. Most modern
human data show little to no thyroid disruption in healthy, iodine-replete adults, but there
are caveats for those with thyroid disease/iodine deficiency or on thyroid meds. Bottom
line: effects are plausible in susceptible people and labels rarely help you personalize risk.
Also, guarana is a high-caffeine stimulant (often stronger than coffee by weight); excess can
raise blood pressure, jitteriness, dehydration not ideal for people prone to hypertension or
kidney issues. And when shakes replace real meals, clients often report fatigue, nutrient
gaps, and yo-yo dieting (behavioral/metabolic cost).
6) Not What’s on the Label
Some reports have found ingredients not listed and undisclosed compounds in certain
batches. This is exactly the kind of problem you see in a sector where products don’t require
pre-market proof of safety or efficacy issues are often caught after people get sick.
7) Mind & Money Trap
Beyond health, the MLM model can pressure people to sell and over-promise. The U.S. FTC
forced Herbalife to restructure and pay $200M in consumer redress over misleading
earnings claims illustrating how the business model itself can harm consumers.
8) Why this keeps happening: Supplements ≠ Medicines
In the U.S. and many markets, supplements are regulated more like foods. Under DSHEA,
the FDA does not approve supplements for safety or effectiveness before marketing. That
means problems often show up after wide use.
If something sounds too good to be true, it usually is. Real results come from balanced nutrition,
training, sleep, and habits not a miracle powder. There are no shortcuts.
