- Subscription
- 10% off; auto-renews at the then-current price until you cancel; discount codes first charge only
Details
Subscribe & Save takes 10% off each delivery on a schedule you choose, and the company says you can pause, cancel or change at any time. The subscription policy (last updated 1 July 2024) is the part to read: the plan renews automatically and your card is charged at the then-current rate until you cancel; discount codes apply only to the first charge unless stated otherwise; and a price rise is notified at least 30 days before the next charge. Changes must be made before an order is charged, through your account on the site or by emailing support@vsl3usa.com. HSA/FSA funds cannot be used for subscriptions — one-time orders only.

- Returns
- No returns at all; report damaged, wrong or incomplete orders within 7 days with photos
Details
The store does not accept returns: the policy says products “cannot be reused or resold once they leave our facility”, which for a refrigerated product is the expected position. Protection is limited to orders that arrive incorrect, incomplete or damaged — email support@vsl3usa.com within seven days of receipt with a description and photos and say whether you want a refund or a replacement. A parcel the carrier marks as delivered cannot be treated as lost. Refund timing is not stated and there is no restocking fee because there is nothing to restock. In practice: open the box the day it arrives, photograph anything wrong, and do not wait for the weekend.

- Delivery
- US only, no PO boxes; VSL#3 ships cold-packed Mon–Thu, about 2 business days by ground
Details
Shipping is within the United States only and not to APO, FPO, DPO or PO Box addresses. VSL#3 (refrigerated) orders are processed Monday to Thursday; an order placed before 1:00 pm ET ships the same business day in cold-pack packaging by FedEx Ground or OnTrac Ground, with delivery typically within two business days, Tuesday to Saturday; Alaska and Hawaii go by FedEx 2Day. Shelf-stable VSL4 ships in 1–2 business days by DHL or UPS and arrives in about three business days (five to Alaska and Hawaii). Shipping is free on multipacks, powders and orders over $101 in the contiguous US; other shipping charges appear at checkout rather than on the policy page.

- Payment
- Card at checkout; HSA/FSA via Truemed on one-time orders after an online health survey
Details
The site does not publish a list of accepted card schemes; the terms only require accurate billing details and let the company cancel orders placed at a mistaken price. For HSA/FSA, choose Truemed at checkout: an asynchronous health survey decides eligibility, after which you pay with an HSA/FSA card or a personal card and Truemed provides reimbursement instructions. Everything in the basket must be a one-time purchase — HSA/FSA is not accepted for subscriptions. Prices seen on 8 September 2026 ran from about $29 for VSL4 capsules to $65.95 for a single box of VSL#3 capsules and up to about $225 for multipacks; powders were $113–$214.

- Support
- Phone and email seven days a week; replies within about one business day
Details
Support is by phone on 866-438-8753 (866-GET-VSL3) or email at support@vsl3usa.com; the returns page lists hours of Monday 7 am–4 pm ET and Tuesday to Sunday 9 am–6 pm ET, and the contact page says the team generally responds within one business day. There is no live chat. The operating company is Actial Nutrition, Inc., 808 S. Public Rd, Suite 202, Lafayette, CO 80026. We found no Trustpilot reviews for vsl3.com on 8 September 2026 (the profile is unclaimed and empty) and did not locate a Better Business Bureau profile for the current operator, so there is no complaint sample to report — which is not the same as a clean record.

- Safety
- Company statements: medical food “under medical supervision”; FDA disclaimer; 2018 false-advertising verdict against former sellers
Details
Two statements from the company itself: VSL#3 “is a medical food intended to be used under medical supervision”, and “These statements have not been evaluated by the Food and Drug Administration. This product is not intended to diagnose, treat, cure, or prevent any disease.” One matter of public record: in 2018 a federal jury in Maryland found the then US sellers of VSL#3 (Alfasigma USA and Leadiant Biosciences) liable for false advertising for claiming the post-2016 product was the same formulation as the original; the Fourth Circuit upheld the verdict on 17 February 2021, and a permanent injunction bars that claim. We make no claim about the current product either way.

Refrigerated VSL#3
Worth it
- The product a clinician named: capsules, powder sachets or double-strength powder, single or multipack
- Order early in the week so the cold pack travels over business days
- Multipacks and powders ship free, but the no-returns rule applies to every box
Skip
- Ordering on a Thursday afternoon or Friday: nothing refrigerated leaves until Monday
- Subscriptions if you want to pay with HSA/FSA funds, accepted on one-time orders only
- Choosing between VSL#3 and VSL4 on marketing copy rather than a clinician’s advice
Check first
- The Monday–Thursday 1 pm ET cut-off, and someone to refrigerate the parcel
- A US street address: PO boxes and military addresses are refused
- The subscription toggle at checkout if you meant to order once
VSL4 shelf-stable supplements
Worth it
- VSL4 is the company’s shelf-stable supplement line, priced at about $29–$55
- No refrigeration or weekday constraint: DHL or UPS, a few business days
- Still a supplement: the same FDA statement and no-returns policy apply
Skip
- VSL4 if you were told to use VSL#3: different products at different strengths
- Multi-box orders on a first purchase: an unopened box cannot be returned
- Treat any effect described on the product page as marketing, not a checked result
Check first
- The listing says VSL4, not VSL#3: the names are easy to confuse
- Free shipping: multipacks, powders and orders over $101, not a single box
- The seven-day window for reporting a wrong or damaged delivery
Questions
Is VSL#3 a supplement or a medicine?
The company calls it a medical food “intended to be used under medical supervision”; its statements “have not been evaluated by the Food and Drug Administration”. It is not a drug, and we do not describe what it does: product choice belongs with your clinician.
Can I return VSL#3 if I change my mind?
No. The store accepts no returns, opened or sealed, because products cannot be resold once shipped. Only orders arriving incorrect, incomplete or damaged qualify: email support@vsl3usa.com within seven days of receipt with photos. A parcel marked delivered is not treated as lost.
What if the cold pack has thawed when the box arrives?
The policy sets no acceptable arrival temperature; it covers damaged orders reported within seven days with photos. Photograph the pack and box on opening and email support that day if anything looks wrong. The product page asks you to refrigerate VSL#3 at 36–46°F on arrival.
What was the VSL#3 court case about?
In 2018 a Maryland jury found the then US sellers, Alfasigma USA and Leadiant Biosciences, liable for false advertising over claiming the post-2016 VSL#3 kept the original formulation. The Fourth Circuit upheld it on 17 February 2021. We make no claim about the current product.
How does the Subscribe & Save plan work?
You pick a delivery schedule and get 10% off each order. It auto-renews at the then-current price until you cancel; price rises are notified 30 days ahead, and promotional codes apply to the first charge only. Cancel before the next charge. No HSA/FSA on subscriptions.
