Why we exist

Looking after yourself shouldn't take a leap of faith.

vivanmn started with a frustration most of our customers share. Shelves full of bottles, and no way to know what was in the capsule, where it was made, or whether the number on the label was true. You were asked to take it on trust.

So we do the opposite. One product, made in the UK. Every batch sent to an independent lab. The results published, not summarised. And 100 days to decide, because we'd rather you tried it properly than bought on a promise.

Most of the people who buy from us are in midlife. They've tried things, they've been sold to, and they turn up sceptical. Hundreds of our reviews open with 'I was sceptical'. We take that as a compliment.

How we work

What we do, so you don't have to take our word for it.

Show, don't claim.

We publish the lab results for every batch and use real numbers only.

Straight about time.

It isn't instant, and nothing we say should make you expect it to be. Give it a fair run. That's why you get 100 days, not 30.

Built to stick.

One capsule, every morning, is the whole routine. The viva app tracks it and reminds you. Your subscription is timed to when you run out, and it's easy to pause or skip.

Real people only.

The reviews are from verified orders, unedited. The photos are our customers'. The team is real, and you can email them.

Fair by default.

Pause, skip or cancel in a couple of taps from your account.

Quality and testing

Nothing to hide.

Every batch follows the same three steps before it reaches you.

  1. Made in the UK. Manufactured here, to UK production standards.
  2. Sent to an independent lab. We send our batches to an independent lab, accredited for heavy metals, to check the NMN content and test for lead, arsenic, cadmium and mercury.
  3. Only passing batches get bottled. If a batch doesn't match the label, it doesn't ship.
