Guarantee
Renew31 guarantee: 60 days, and the 30-day band in it
The material supplied with this stock states two things about the guarantee. 60-day window from purchase. And: Sales also asks for at least 30 days of use. Confirm live checkout. Both are published here verbatim, because a 60-day window with a 30-day use expectation beside it leaves a 30-day band in which a buyer has satisfied one condition and not the other. At one gummy a day a bottle is exactly 30 days, so two bottles is 60 days against a 60-day window and the two close on the same day, leaving 0 bottles sealed. Three bottles leaves 30 days of product outside the window and one bottle sealed; six leaves 120 days outside and 4 bottles sealed, which is $196 at the pack price. Whether a sealed bottle can be sent back is not published.

The guarantee, in under a minute
Read time under a minute- Two sentences were supplied, and they are both published on this page verbatim. One sets a 60-day window from purchase. The other asks for at least 30 days of use.
- The two leave a 30-day band. Decide before day 30 and the use expectation is unmet; decide after day 60 and the window has closed.
- Two bottles leaves nothing sealed. 60 days of product against a 60-day window, so 0 unopened bottles on the day it closes.
- One route to claim it: the order desk on +1 (302) 200-3480. The website desk cannot credit a card.
What the promise actually is, in its own words
Two sentences arrived with this stock, and they are published here exactly as supplied, because the gap between them is the thing a buyer needs.
The guarantee, as supplied, and the second condition inside it
60-day window from purchase. And: Sales also asks for at least 30 days of use. Confirm live checkout.
Both are published verbatim. A 60-day window with a 30-day use expectation leaves a 30-day band in which a buyer has satisfied one condition and not the other.
60 days, from purchase
The window published with this stock. It starts on the day you buy.
At least 30 days of use
Asked for in the same material, beside the window, with no link drawn between them.
One route to claim it
The order desk on +1 (302) 200-3480. The website desk at [email protected] cannot credit a card.
The first sets a window and says when it starts: at purchase, not at delivery. The second sets an expectation about use. Neither mentions the other, and nothing supplied says what happens to a claim that meets one and not the other.
What a guarantee is not is evidence. It is a promise about money, made by the party selling the product. NCCIH, on this category: “We also don’t know how much of the probiotic people would have to take or who would be most likely to benefit.” NCCIH
The supply against the window, pack by pack
Two bottles is 60 days of product against a 60-day window, so the supply and the window close on the same day. Three bottles is 90 days, which leaves 30 days of product outside it. Six is 180 days, which leaves 120 outside.
| Pack | Days of product | Outside the window | Still sealed | At the pack price |
|---|---|---|---|---|
| 2 Bottles | 60 days | 0 days | 0 bottles | Nothing |
| 3 Bottles | 90 days | 30 days | 1 bottle | $69 |
| 6 Bottles | 180 days | 120 days | 4 bottles | $196 |
At one gummy a day the two-bottle pack empties on day 60, and day 60 is the day the window shuts. So on that pack there is no unopened bottle left to send back: 0 sealed bottles, not one. On three bottles 1 is still sealed and on six, 4.
The two-bottle row is worth sitting with. A buyer who takes the small pack to keep the risk small has the least to send back: the last gummy and the last day arrive together. On six bottles 4 are still sealed when the window shuts, $196 at the pack price.
Renew31, from $49 a bottle. 30 gummies at 1 gummy a day, so a bottle is 30 days.
- 60-day money-back guarantee
- Free US shipping on 3 and 6 bottles
- 30 gummies a bottle, 1 gummy a day
The 30-day band between the two sentences
A 60-day window with a 30-day use expectation inside it divides the calendar into three, and only the middle stretch satisfies both.
| When you decide | Window | 30 days of use | What that leaves |
|---|---|---|---|
| Day 1 to day 29 | Open | No | Inside the window, short of the use expectation |
| Day 30 to day 60 | Open | Yes | Both satisfied: the 30-day band |
| Day 61 onwards | Closed | Yes | Use expectation met, window gone |
The middle row is the only one in which both conditions hold, and it is 30 days wide rather than 60. Nothing supplied says what happens to a claim made in the first row, which is the row most buyers who want their money back will be standing in.
Both sentences came from the seller, side by side, and neither qualifies the other, so this page publishes both and resolves neither. Confirm live checkout. The two places that can say which terms your order was placed under are the live checkout and the order desk on +1 (302) 200-3480.
On the two-bottle pack the use expectation is met on day 30 and the window closes on day 60, so the band is the second half of the pack. On six bottles the band is the same 30 days, and 120 days of product sit beyond it.
Is 60 days enough for this product?
The honest answer depends on answers only you have, so here are the five questions rather than a verdict.
Five questions about the 60-day window
Nothing is sent anywhere and nothing is stored. The questions are the ones the two supplied sentences make necessary.
Do you expect to decide inside 60 days of buying?
Can you take it for at least 30 days before you decide?
Are you buying more than two bottles?
Do you need an unopened bottle to be refundable?
Have you read the guarantee on the live checkout yourself?
Settle that one before you pay, not after
Two things on this page are not published: whether a sealed bottle can be sent back, and whether anything is deducted. Confirm live checkout. The answer you need is the one on the live checkout on the day you buy, and the order desk on +1 (302) 200-3480 is where to get it.
The window fits, with one figure to check
A pack that lasts longer than 60 days means the last stretch of it is outside the window by the time you reach it: 120 days of the 180 on six bottles. Worth knowing before you choose the pack.
The arithmetic is straightforward on your answers
Two bottles is 60 days against a 60-day window, so the two close together and 0 bottles are left sealed.
Two of the five are stops. If your plan depends on sending an unopened bottle back, nothing supplied tells you whether that is allowed. And the guarantee on the live checkout governs your order, not the wording reproduced here.
The seller supplies a figure for how long buyers wait before a view forms, 3 to 6 weeks. It is reproduced on the reviews page as the seller’s and nowhere as a fact, because “We also don’t know how much of the probiotic people would have to take or who would be most likely to benefit.” NCCIH
How a refund is actually claimed
One route, one telephone number, and three details to have in front of you.
Call the order desk on +1 (302) 200-3480
Order support - tracking, changes and refunds. It is the only contact that can credit a card.
Have the order email open
Full name, email address and order ID.
Ask what the desk wants sent back
No sealed-bottle rule and no deduction is published in anything supplied with this stock, so the desk is the only authority on it.
Send what the desk asks for, with tracking
The buyer pays return shipping, and should use a tracked service.
Expect two stages, not one
3 to 5 business days after they credit the return, then 5 to 10 days for the card to show it.
The website desk cannot see orders. There is no order screen at that address, no tracking view and no way to issue a refund. Anything involving money, a parcel or a change to an order goes to the order desk on +1 (302) 200-3480. The hours the order desk keeps are not published. The Monday to Friday, 9:00am - 5:00pm ET window published with this stock belongs to the website desk, which cannot see an order, so this site prints the order number and leaves its opening times blank rather than borrowing somebody else’s working day.
The refund page sets the sequence out in full, including the returns address and the two-stage timing: 3 to 5 business days after they credit the return, then 5 to 10 days for the card to show it. The contact page sets the two published addresses side by side.
60 days to change your mind, on every pack
Two bottles is $158, three is $207 and six is $294, with the same window on all three. The order desk on +1 (302) 200-3480 is the route.
