Who Is VSL Pharmaceuticals and Why Are They Being Sued for False Advertising?

VSL Pharmaceuticals, along with Leadiant Biosciences and Alfasigma USA, licensed, marketed, and sold VSL#3 — a high-potency probiotic used for conditions like ulcerative colitis, irritable bowel syndrome, and pouchitis. For years, the product’s marketing leaned on clinical studies tied to a specific bacterial blend. Buyers allege the companies kept using that reputation after the underlying formula changed.

What Did VSL Pharmaceuticals Do to Buyers Between 2016 and 2019?

Here’s the core claim. VSL#3 was originally built on what court records call the “De Simone Formulation,” a proprietary bacterial blend developed by Professor Claudio De Simone. Buyers say that around 2016, the defendants lost the rights to sell that formulation — and quietly started selling a different one under the same VSL#3 name. The lawsuit alleges they kept citing the old clinical studies and scientific backing without telling anyone the ingredients had switched.

That’s the legal hook for a RICO claim, a federal law usually reserved for organized fraud schemes. It also drives the breach of warranty and unjust enrichment counts: if you’re promised the tested formula and get something else, you arguably overpaid. This kind of ingredient-swap allegation shows up more than you’d think in supplement litigation — the Joint Juice $90 million false advertising settlement followed a similar pattern of health claims outrunning the science behind them.

Defendants deny all of it. They haven’t been found liable for anything — the case settled first. But if you bought VSL#3 in that window, this is about you either way.

Who Qualifies for the VSL#3 False Advertising Settlement?

Here’s exactly how to know if this case includes you.

• Anyone who purchased VSL#3 anywhere in the United States between June 1, 2016, and June 19, 2019
• Households that bought VSL#3 through a retailer, pharmacy, or online, with or without a receipt
• People who received a postcard or email notice from the settlement administrator
• Buyers who no longer have the product or packaging — you don’t need to have kept it

You do not qualify if you’re an officer, director, or employee of the defendant companies, bought VSL#3 only to resell it, or are part of the presiding judge’s staff or family.

VSL#3 Buyers Outside the U.S. — Are You Still Covered?

The Settlement Class is nationwide. It covers anyone who bought VSL#3 in the United States during the class period, regardless of which state they live in now. If you purchased outside the U.S., you’re not part of this settlement — similar supplement cases like the Balance of Nature $9.95 million settlement have also been limited to U.S. purchases.

That’s the whole test. No income limits, no health outcome to prove, no need to show you got sick — just a purchase in the window.

Not sure if you qualify for the VSL#3 false advertising settlement? A free consultation with a consumer fraud attorney can help before the October 20, 2026, deadline.

How Much Can VSL#3 Settlement Class Members Get? Up to $800 Per Person

You can receive $20 for every unit of VSL#3 you bought — a unit is one bottle or box, and multiple bottles in a multipack each count separately.

VSL#3 Payout With Proof of Purchase — Up to $800

If you have receipts, or your name shows up in retailer records tied to your Notice credentials, you can claim for up to 40 units. That caps out at $800 before any adjustment.

VSL#3 Payout Without Proof of Purchase — Up to $20

No receipts? You’re limited to one unit per household — a flat $20, again before adjustment.

What Pro-Rata Means for Your VSL#3 Check

More filers means smaller checks, and fewer filers means bigger ones. If total valid claims come in under the available fund, payouts increase — up to three times the stated amount. If claims exceed the fund, payouts shrink proportionally. You won’t know your exact number until claims close.

Payments go out roughly 60 days after the settlement becomes final. Payments over $600 may appear on a 1099. Check with a tax professional. Honestly, $20 a bottle looks modest — but if you bought VSL#3 regularly over three years, those units add up fast.

Should VSL#3 Class Members Opt Out or Object Before October 20, 2026?

What Opting Out of the VSL#3 Settlement Actually Means

Opting out means you get no payment from this settlement. In exchange, you keep your right to sue the defendants yourself over these same VSL#3 purchases. Most people should not opt out without talking to a lawyer first. The opt-out deadline is October 20, 2026.

How to Object to the VSL#3 Settlement

Objecting keeps you in the Class but tells the court you disagree with the terms. Written objections must go to the U.S. District Court for the District of Maryland, 6500 Cherrywood Lane, Greenbelt, MD 20770, with a copy to Class Counsel, and must include the case number and your grounds for objecting.

Talk to a class action lawsuit attorney before October 20, 2026, if you’re considering either option.

VSL#3 False Advertising — Frequently Asked Questions, No. 8:19-cv-02173

Do I need a lawyer to file a VSL#3 settlement claim? 

No. The claim form at vsl3lawsuit.com is designed for consumers to file a legal claim without an attorney. A consumer rights lawyer is only worth consulting if you’re weighing opting out.

Is the VSL#3 settlement legitimate? 

Yes. It’s a $20 million settlement approved on a preliminary basis by Judge Lydia Kay Griggsby in the U.S. District Court for the District of Maryland, administered by Angeion Group.

When will VSL#3 settlement payments be sent?

 The parties proposed paying claims within 60 days of the Effective Date, but that depends on the Final Approval Hearing on January 6, 2027, going forward without delay.

What if I missed the VSL#3 claim deadline? 

Claims postmarked or submitted after October 20, 2026, are typically rejected. Contact the administrator at 1-844-942-4216 to ask about your specific situation.

Will my VSL#3 settlement payment go on a 1099?

 Possibly. Payments over $600 may be reported. Check with a tax professional about your lawsuit settlement payout.

Do I need a receipt to file a VSL#3 claim?

 No, but it caps your payout at one unit. Proof of purchase — a receipt or your Notice credentials — unlocks claims for up to 40 units and a bigger check.

What happens if I do nothing? 

You get no payment, and you give up your right to sue the defendants later over these same claims. Filing is the only way to see any class action settlement payout from this case.

Who are the defendants in the VSL#3 lawsuit? 

VSL Pharmaceuticals, Inc.; Leadiant Biosciences, Inc. (formerly Sigma-Tau Pharmaceuticals); and Alfasigma USA, Inc. — the companies that licensed, marketed, and sold VSL#3 during the class period.
