The system

What is 31VITAL?
A supplement subscription built around a single date. You choose which products you want, they arrive together in one box, and they renew together on one date every 31 days. One box, one date, one charge.

Why 31 days?
Because the alternative is what most people currently have: three or four products bought in different places, running out on different days, billed on different dates. Every bottle in your box holds at least 31 days at its stated serving, so nothing runs out ahead of the rest. One a day is 31 in the bottle, two a day is 62, three a day is 93.

Why not 30?
A 30 day bottle runs out on the morning your next box is still in transit. The extra day is the overlap that stops you having a gap.

Do I have to subscribe?
No. You can order any product once, without a subscription. The subscription is what the brand is built for, but it is a choice, not a condition.

Can I add something halfway through a cycle?
Yes. It ships immediately as a separate order and your existing renewal date does not move. If that means a few days of overlap on the new product, that is on us, not on you.

Can I change what is in my box?
Any time, from your account. Add, remove, swap. The change applies from your next renewal.

Your subscription

When am I charged?
On your renewal date, every 31 days. We email you before every single charge telling you what is about to ship and what it will cost, with a link to change or cancel it.

How do I skip a cycle?
In your account. One click. Your date stays where it is and the next box ships as normal.

How do I pause?
Also in your account, for up to three months. A pause holds everything until you restart it. Nothing is lost and nothing is charged.

How do I cancel?
In your account, in the same number of clicks it took to subscribe. No phone call, no chat, no offer you have to decline three times. If you would rather email, write to support@31vital.com and we will do it for you.

When does cancelling take effect?
Immediately. It stops every future charge from that moment. If we have already charged and shipped that cycle's box, tell us and you can send it back unopened for a full refund including your return postage.

What happens if my payment fails?
We email you and retry a few times over several days. If it still does not go through, we pause your subscription rather than cancelling it, so nothing is lost when you update the card.

Can I get my old stack back after cancelling?
Yes. Your stack stays saved on your account. Restarting takes one click.

Ordering and payment

How can I pay?
Card, Apple Pay and Google Pay. All prices are in US dollars.

Will I be charged import duties or taxes?
No. Orders outside the United States ship delivered duty paid, which means we settle the duties and taxes before your parcel reaches you. If a carrier ever asks you for money before handing over a 31VITAL parcel, do not pay it. Email us.

Can I change or cancel an order after placing it?
Within 24 hours, yes. Email support@31vital.com with your order number. After that it is usually with the carrier and we cannot redirect it.

Is there an age limit?
Yes. You must be 18 or older to order.

Shipping

Where do you ship?
The United States including Alaska and Hawaii, Canada, the United Kingdom, Australia and New Zealand.

Is every product available in every country?
No. Supplement rules differ by country and some ingredients sold freely in one market are restricted in another. Melatonin is the clearest example: prescription-only in the UK, regulated in Australia. Anything affected simply will not be available at checkout in that country, so you find out before you pay rather than after.

What does shipping cost?
Nothing. Free on every order, in every country, at any size. No minimum, no handling fee, no surcharge added later.

How long does it take?
1 to 3 business days to process, then 5 to 8 business days in transit. Roughly 6 to 11 business days in total. These are estimates, not guarantees, and customs is the part we control least.

What if it takes much longer than that?
We email you, and you can cancel for a full refund instead of waiting. You do not have to ask for that or argue for it.

How do I track it?
You get a tracking link by email as soon as your parcel is handed to the carrier. International parcels often go quiet for a few days while clearing customs. That is normal.

My tracking says delivered but nothing arrived.
Check with neighbours, your mailbox, and any parcel locker or pickup point first, since this resolves it most of the time. If it still has not turned up, email support@31vital.com. We open a case with the carrier and then replace or refund it. You are not left arguing with a delivery company on your own.

Will everything arrive together?
That is the point, and usually yes. Occasionally a stock issue splits a box. If that happens we tell you rather than letting you wonder, and you are never charged twice for shipping.

Returns and refunds

What if a product is not right for me?
You have 30 days from delivery to send it back, unopened and with the seal intact, for a full refund. Return shipping is paid by you.

Can I return an opened bottle?
Not if you have simply changed your mind. A supplement that has left our control and been opened cannot safely go to anyone else. If the product is faulty, wrong or damaged, that rule does not apply and you get a full refund whether it is opened or not.

Do you do exchanges?
Yes. Send the unopened bottle back within 30 days and we ship the replacement free. You cover the return, we cover the outbound. If we sent the wrong thing, we cover both.

Something arrived damaged, or something was missing.
Email support@31vital.com within 48 hours of delivery with photos of the outer parcel and the bottles. The window is short because carriers require damage claims quickly. We replace or refund in full and you do not send anything back.

I got the wrong product, or it is faulty.
You have 30 days. Same outcome: replacement or full refund, nothing to send back, and we pay any postage.

How long until I get my money?
We process approved refunds within 5 to 8 business days of receiving and checking your return. Your bank then takes its own time on top, usually a few days.

I forgot to cancel and got charged.
Tell us. If it has not shipped, we cancel and refund it in full. If it has, send it back unopened within 30 days and we refund it in full including your return postage. A forgotten renewal is not something we want to profit from.

What is in them

What is in the capsules?
Everything is on the label, and the label is the authoritative source. We publish the full ingredient panel on every product page too, including the inactive ingredients, which is the part most brands leave off.

How many capsules are in a bottle?
It depends on the daily serving, and it is on the product page and the label. One a day is 31, two a day is 62, three a day is 93.

Do you have allergen information?
On every label and every product page. Across the current range: fish appears in marine collagen, omega 3 and astaxanthin, dairy in colostrum, and shellfish in glucosamine. If you have a serious allergy, read the label on arrival as well as the product page, because that is the version that applies to the bottle in your hand.

What if I take two products with the same ingredient?
The amounts add up, and seven ingredients appear in more than one of our stacks. When you build a stack that doubles something, we show you the combined daily total before you check out. Biotin is the one worth naming: at higher daily amounts it can interfere with laboratory blood tests, including the troponin test used to assess chest pain. Tell any doctor or lab that you take it.

How should I store them?
Somewhere cool and dry, out of direct sunlight. If your box has been sitting in a hot mailbox in summer, bring it in when you can. Keep the product in its own bottle rather than decanting, so you always have the best before date and the lot number.

Taking them safely

Can I take these alongside my medication?
Ask your doctor or pharmacist. Supplements can interact with prescription medication, and we do not know your history, your dose or your condition. This is not us being cautious for legal reasons. It is the one question we genuinely cannot answer for you. What we can do is send you the full ingredient list and amounts for everything in your stack so you can hand it to them. Ask and you will have it the same day.

I am pregnant or breastfeeding.
Speak to your healthcare provider before taking anything from us.

What if I have a reaction?
Stop taking it and speak to a healthcare professional. Then tell us at support@31vital.com with the product name and the lot number from the bottle. We log every report and pass it on. You get a full refund in this situation whether the bottle is opened or not.

Do you ask me health questions to build my stack?
No. You choose from goals. We do not ask what is wrong with you and we do not build a health profile on you.

The part other brands bury

How long before I notice anything?
Longer than most marketing suggests. Sleep and digestion tend to show first, usually somewhere between weeks two and four. Skin, hair and nails are the slowest of all and need a full three months before there is anything to judge. Some people do not notice much at all, and that depends on where you were starting from.

Do these products work?
We are not permitted to tell you a supplement treats, prevents or cures anything, and we would not want to, because we would be guessing about your body. What we will tell you is exactly what is in each product, at what dose, and what it costs. What you do with that is yours.

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.

Still have a question?
Email support@31vital.com. We reply within one business day, every time.
