VSL Pharmaceuticals, Leadiant Biosciences and Alfasigma USA have agreed to pay $20 million to settle claims that buyers of the VSL#3 probiotic were told the formulation on the shelf had been proven effective in clinical testing when the clinical evidence did not apply to it. The benefit is $20 per unit — one unit per household with no proof at all, up to 40 units ($800) with receipts. Claims close October 20, 2026. The defendants deny the allegations.

What the case alleged
VSL#3 is a consumer probiotic sold in bottles and boxes through retailers and online. The defendants are the companies that licensed, marketed and sold it during the class period.
The plaintiffs alleged that the defendants falsely represented that the formulation of VSL#3 sold during the class period had been proven effective in clinical testing — the substance of the claim being that the clinical evidence buyers were pointed to did not apply to the version actually on the shelf during that window, and that purchasers therefore overpaid.
The defendants dispute those allegations. The court has certified the case to proceed as a class action under Rule 23, but it has not decided whether the plaintiffs’ claims are correct, and the notice states plainly that the settlement does not mean any law was broken or that the defendants did anything wrong.
This is a pricing and labeling case, not an injury case — a distinction that carries through to what the settlement releases.
Who qualifies?
You are a class member if you purchased VSL#3 in the United States between June 1, 2016 and June 19, 2019. There is no requirement that you be a repeat buyer or have any ongoing purchase history — a single qualifying purchase in that window is enough.
You are excluded if you are an officer or director of Alfasigma, Leadiant or VSL, or of their parents, subsidiaries or affiliates, or of any entity in which the defendants hold a controlling interest; if you purchased VSL#3 exclusively for resale to a consumer; or if you are a judge assigned to any part of this litigation, that judge’s staff or immediate family, or class counsel, their staff or their immediate family.
Receiving a postcard or email notice means sales records suggest you may have purchased VSL#3 during the class period. It is not a determination that you are a class member or that you will be paid.
How much can you get?
The benefit is $20 per unit of VSL#3 purchased. A unit is a bottle or box — and in a multipack, each bottle counts as its own unit, so a three-bottle pack is three units rather than one. That detail is easy to miss and it changes the math on a typical purchase.
| Route | What you can claim |
|---|---|
| No proof of purchase and no notice | One unit per household, or $20. You certify you bought at least one unit in the class period. |
| With proof of purchase | The greater of three units or the total number of units you can document — so any receipt at all is worth at least $60 rather than $20. |
| Maximum | 40 units, or $800, per the notice. |
Notice credentials count as proof. If you received a notice containing a notice ID and confirmation code, that means class counsel obtained records of your purchases from the defendants and certain retailers, and filing with those credentials credits you for the units in those records. If your own receipts show more units than the records do, you can submit the receipts instead and claim the larger number.
The $20 is a starting figure, not a guarantee. If the total value of valid claims comes in under the money available, per-unit payments increase pro rata — but the notice caps that increase at three times the stated amounts. If valid claims exceed the money available, per-unit payments are reduced pro rata.
The $20 million fund is reduced before any of it reaches class members: court-approved notice costs, administration costs, attorneys’ fees and expenses, and service awards all come off the top. Class counsel will seek up to one third of the fund — up to $6,666,666.67 — plus reasonable expenses, and up to $10,000 for each class representative. The fee request is due to be filed by September 21, 2026, before the October 20 objection deadline, so anyone who wants to see the actual numbers before deciding whether to object can check the settlement website after that date.
What proof do you need?
None, for the minimum claim. This settlement has a genuine no-proof tier: with no notice credentials and no receipts, you may claim one unit per household by certifying that you purchased at least one unit of VSL#3 between June 1, 2016 and June 19, 2019.
Proof is what raises the ceiling. The claim form offers three routes:
- Notice credentials. Enter the notice ID from your personalized email or postcard notice and claim the units reflected in the records already obtained.
- Your own records. Attach proof of purchase such as receipts and write in the total number of units documented. If you received a notice and also have receipts, you may claim under whichever option yields more units.
- Certification only. No notice, no receipts, one unit per household.
Claims may be subject to audit, verification and court review, and the form is signed under an affirmation that the statements are true and accurate.
What are the deadlines?
October 20, 2026 is the operative date for all three choices, which is unusual — on many settlements the opt-out deadline falls earlier than the claim deadline. Here they coincide.
- Submit a claim — postmarked or submitted online by October 20, 2026.
- Exclude yourself — a written exclusion request must be mailed by October 20, 2026. A sample exclusion form is on the settlement website. Opting out means no payment, but you keep any right to sue the defendants separately over your VSL#3 purchases.
- Object — objections must be filed with the court, with copies to class counsel, by October 20, 2026, and must meet the content requirements in the notice, including the case name and number, your contact details, signature, the specific grounds, and whether you intend to appear at the hearing.
Doing nothing means no payment and no preserved right to sue — you stay in the class and are bound by the release.
How to file a claim
Claims are submitted through the official settlement website, VSL3Lawsuit.com, administered by Angeion Group, or by mailing the completed and signed paper claim form attached to the notice.
The payment method depends on how you file. Filing the paper form is treated as electing payment by check. PayPal, Venmo, Zelle and virtual prepaid card are offered only on the online claim form. If you want an electronic payment, file online.
The online portal asks first whether you have a notice ID and confirmation code. If you do, you log in with them. If you did not receive a notice, the portal lets you enter an email address to receive a code and proceed to the full claim form, so a missing notice is not a barrier to filing.
What you give up
Filing a claim, or simply doing nothing and remaining in the class, releases your claims against the defendants relating to the purchase or use of VSL#3 products, the marketing representations about them — including statements or omissions about clinical studies, ingredients, efficacy, and where VSL#3 is manufactured — and any claims that were raised or could have been raised within the scope of the facts asserted in the litigation. The release reaches known and unknown claims.
One carve-out is worth stating plainly: the released claims do not include legal claims for personal injury. This settlement is about having overpaid for the product, not about harm to health. Anyone who believes they were physically harmed and is weighing what this release does and does not cover should talk to a lawyer about their own situation rather than rely on a summary.
What happens next?
Class counsel’s application for attorneys’ fees, costs, administration expenses and service awards is due to be filed by September 21, 2026, and will be available through the settlement website. The final approval hearing is set for January 6, 2027 at 2:30 p.m. at the U.S. District Court for the District of Maryland in Greenbelt.
The notice warns that the hearing may be moved to a different date or time without further notice and that the settlement website will be updated with any change. Class members do not need to attend to receive a payment.
If the court grants final approval, the parties have proposed that benefits be paid within 60 days after the effective date. No payment date has been announced, and the notice is explicit that the timing of final approval is not known and that distribution could be delayed.
Frequently Asked Questions
What counts as a unit of VSL#3?
A unit is a single bottle or box. In a multipack, each bottle counts separately — three bottles packaged together count as three units, not one. That matters because the benefit is calculated per unit, so a multipack purchase is worth more than the number of transactions on a receipt would suggest.
Could my payment be more or less than $20 per unit?
Both are possible. If the total value of valid claims comes in below the money available, per-unit payments increase pro rata, but the notice caps that increase at three times the stated amounts. If claims exceed the available money, per-unit payments are reduced pro rata.
I got a notice but I also kept my receipts. Which should I use?
Use whichever shows more units. Notice credentials reflect the purchase records class counsel obtained from the defendants and certain retailers, and they count as proof of purchase for the units in those records. If your own receipts show more purchases, submit that proof instead.
Why can’t I get an electronic payment on the paper claim form?
The paper form is check-only by design — filling it out is treated as electing payment by check. PayPal, Venmo, Zelle and virtual prepaid card are offered only through the online claim form on the official settlement website.
Does this settlement release a personal injury claim?
No. The release is broad and covers claims relating to the purchase, use and marketing of VSL#3 products, but it states expressly that released claims do not include legal claims for personal injury. Anyone weighing that distinction should speak with a lawyer.
